Antennal arista pectinate; bases of the antennae separated by a flattened carina.
Antennal arista short or long-plumose; neither sex with distinct orbital bristles.
Oral margin produced snout-like; vibrissa placed high above the oral margin; antennal arista either pectinate or more or less plumose.
It is related to Culicoides but differs in the number of antennal segments and in its wing venation (fig.
Sections of the third antennal segment not branched.
First two antennal segments very short, last two long, pilose, third thickened at the base; ocelli present, veins of the hemelytra forming cells.
Last antennal segment clavate or fusiform; win membrane with the veins often forked and anastomosing; scutellum large; tarsi each with two segments; fore legs strong.
The distal of the four antennalsegments is slightly club-shaped.
In the higher forms, as already mentioned, the antennal ganglia have become shifted forwards and coalesced with the brain.
In the Decapoda the antennal gland is largely developed and is known as the "green gland.
The centres for the antennal nerves form ganglionic swellings on the oesophageal connectives.
In the Decapoda, where the antennal gland alone is well-developed in the adult, the maxillary gland sometimes precedes it in the larva.
Behind the antennal (or deutocerebral) segment an "intercalary" or tritocerebral segment has been demonstrated by W.
It grows to a length of over 4 inches, and has a long serrated rostrum extending beyond theantennal scales and curving upwards at the point.
The antennal tube keeps open a channel leading from the buried Crab to the water above.
In Cryptolithus they appear to be beside the anterior lobe of the glabella under what have long been known as the antennal pits.
There may or may not be a slight ridge running lengthwise of the naked part of the antennal club.
The Common Skippers are smaller, and have very large heads with theantennal clubs drawn out and recurved.
In Nebalia, feeding experiments with alizarin blue and carmine stained the antennal glands, and showed the existence of glands at the base of the eight thoracic feet.
The downwardly directed head is covered by the pronotum, and the three terminal antennal segments form a distinct club.
The number of antennal segments varies from eleven to two.
In this family there is often a marked divergence between the sexes; the terminal antennal segments are larger in the male than in the female, and the males may carry large spinous processes on the head or prothorax, or both.
Deutocerebrum: the middle portion of the brain, formed by the ganglion of the 2d primary segment; also termed antennal or olfactory lobes from the parts it innervates.
Facialium -ia: Diptera; that portion of the face between the lower part of the frontal fissure and the antennal fovea.
Mostly large, convex and short bodied Beetles with large thorax, broad head, lamellated antennal clubs, spinose tibiæ and pentameral tarsi.
In the higher insects it is accomplished by antennal contacts, in man by speech.
Their antennal language is capable of manifold expression; it suits the interior of the nest, where all is dark.
Above the antennae are expanded antennal scales, which, together with the long bases of the antennules and very prominent eye-stalks, make the head a broad and conspicuous feature.
The antennal scales are oblong and fringed with hair.
As in all shrimps, the antennae are long and have plate-like antennal scales at the base, which are fringed with hairs.
In many genera of springtails a curious post-antennal organ, consisting of sensory structures (often complex in form) surrounded by a firm ring, is to be noticed on the cuticle of the head between the eyes and the feelers.
Other sensory organs occur on the third and fourth antennal segments in the Achorutidae and Entomobryidae (fig.
Spence Bate writes to me: "Apseudes, as far as I know, is the ONLY Isopod in which the antennal scale so common in the Macrura is present on the lower antenna.
The optic was large, the tegmental a little smaller and the first antennal about as large as this last.
Male: The characteristic genitalia and antennal joint are figured.
But the latter undoubtedly draw similar inferences from the data derived from their topochemical antennal sense.
For of such a nature is the position of the olfactory sense on the antennal club of the ant.
The topochemical antennal sense also furnishes splendid proofs of memory in ants, bees, etc.
A genuine topochemical antennal sense is, therefore, probably best developed in all arthropods, whose antennæ are not only movable in the atmosphere, but adapted to feeling of objects.
But I will here assume these questions to be known and answered, nor will I indulge in polemics with Bethe and his associates concerning the propriety of designating the chemical antennal sense as “smell.
Now all the workers of the African species of Dorylus and of many of the species of Eciton are totally blind, so that they must orient themselves exclusively by means of their antennal sense.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "antennal" in a variety of sentences. We hope that you will now be able to make sentences using this word.
