132 AMERICAN ENTOMOLOGY. 



Cubital-cellule, 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 sulmarginal 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. 



Cuspidate, prickly-pointed ; ending in a sharp point ; an acu- 

 minated point ending in a bristle. See mucronate. 



Cursory, formed for running. See natatory. 



Cyathiform, wineglass-shaped ; more or less obconical and con- 

 cave. See calatliiform, acetabuliforrn. 



Gyaneus, dark-blue, like prussian-blue. 



Cydariform, globose, but truncated at two opposite sides. 



Cymbiform, boat-shaped; navicular. 



D. 



Deciduous, falling off easily. See caducus. 



Decrepitant, crackling. 



Decumbent, bending down ; upright at base, and bending down 

 at tip. See procumbent. 



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



Decurved, bowed downwards. See cxcurved. 



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. 



Dehiscent, gaping; open or standing open; deeply ernarginate. 



Deltoid, triangular spear-shaped; trowel-shaped; having the 

 general appearance of a triangle, with the terminal angle much 

 further from the base than the lateral ones.
