AMERICAN ENTOMOLOGY. 125 



Annidus, a ring; the circumference of the gula in which the 

 lora terminates ; a term applied to colored rings upon the body 

 or members, differing from a band, by being continued quite 

 round. 



Antennae, two articulated organs of sensation, situated on the 

 head ; in the Hymenoptera particularly, they are divided into 

 radicida, sea/pus, pedicellus, and apex; they are monili/orm, 

 setaceous, clavate, &c. 



Anterior angle, of the thorax, is the lateral angle near the head 

 on each side. 



Anterior margin, the margin on the anterior side of the wings, 

 extending from the base to the apex; the costal margin; 

 opposite to the posterior margin. 



Anterior palpi, the labial palpi. 



Anterior icings, the superior wings. 



Antipoivltimate, the last but two. 



Anus, the apex of the abdomen, in which the organs of genera- 

 tion in most insects are attached or concealed; including fim- 

 bria, aculeus, and penis. 



Apex, in general indicates the terminal portion of any organ or 

 part of the body ; (of the wing) it is that part or angle which 

 is opposed to, or at the greatest distance from, the base ; (ligula) 

 the portion which is not included in the tubus; (maxillae) that 

 portion which is above the palpus. 



Apicxdate, covered with fleshy, erect, short points. See vcrru- 

 cose. 



Apodal, (larvae) with simple tubercles instead of feet. See 

 geometrse. 



Apophysis, the coxse ; the two small basal joints of the feet. See 

 trochanter and flocculus. 



Approaching, converging. 



Approximate, near to, near together ; (antenna)) close together 

 at base. 



Aptera, insects without wings ; many of the Coleoptera are des- 

 titute of wings, and in most of such species the elytra are 

 inseparable : the females of several species of the Lepidoptera 

 are also destitute of wings ; as are also some of the Hymenop- 

 tera. 



Arachnoideous, cobweb-like ; resembling a cobweb.
