132 AMERICAN ENTOMOLOGY. 



Cubitalrcellule, a portion of the superior wing, included be- 

 tween the nervure of the radial cellule and a nervure which 

 originates near the extremity of the cubitus, and runs in a 

 curvilinear direction towards the extremity of the wing; it is 

 complete if this nervure reaches the posterior edge, and incom- 

 plete if the nervure is abbreviated ; it is often divided into two 

 or three parts by transverse nervures ; when one of these parts 

 or small cellules appears to be supported by a petiole it is 

 termed a petiolated cellule ; it is called submarginal cellule by 

 some authors. 



Cubitus, the second nervure of the exterior margin of the wing, 

 extending from the base to the carpus ; it is separated from 

 the radius by an intermediate membrane. 



Cucullate, cone-shaped ; hooded. 



Cultrate, shaped like a pruning-knife. 



Cuneiform, wedge-shaped ; broad and truncated at one end, and 

 attenuated to the other. 



Cupreous, coppery ; the color of copper. 



Cwspit/a^e, prickly-pointed ; ending in a sharp point; an acu- 

 minated point ending in a bristle. See mucronate.

Deciduous, falling off easily. See caducus. 



Decrepitant, crackling.

 at tip. See procumbent. 



Decurrent, closely attached to, and running down another body. 



Decurved, bowed downwards. See excurved. 



Decussated, in cross-pairs; pairs alternately crossing each other. 



Deflected, bent downwards; (wings) incumbent but not hori- 

 zontally, the outer edges declining towards the sides.
