AMERICAN ENTOMOLOGY. 125 



A)inidus, a ring; the circumference of the (/ula 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. 



Antennse, two articulated organs of sensation, situated on the 

 head ; in the Hymenoptera particularly, they are divided into 

 radicida, scapus, 2^cdicedi(s, and (q)c.i- ; they are monillformj 

 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 banc to the a^icx ; the costal margin; 

 opposite to the jxjsterior margin. 



Anterior palpi, the labial paljji. 



Anterior wings, the superior tcings. 



Antipemdtimate, 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 ^m- 

 hria, 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 ; (maxillas) that 

 portion which is above the paJpus. 



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

 cose. 



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

 geometrse. 



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

 trochanter and Jloccidus. 



Approaching, converging. 



Approxiinate, near to, near together ; (antcnnge) 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. 



Arachnoidcous, cobweb-like ; resembling a cobweb.
