CROP PEST COMMISSION OP 



Dorsal and ventral areas striate, striae entire, distinct, and not 

 very fine; lateral striation a little finer, that of the prothorax verj 

 fine, with a small smooth spot adjoining the smoother surface of its 

 ventral area; latter shorter than dorsal, not including anterior 

 pair of setae, medium sulcus scarcely dull pubescent. Meso- and 

 metathorax with lateral impressed lines, and dull pubescent pale 

 annuli, but the lateral lines almost without pubescence. Fleshy false 

 feet of abdominals rather prominent, dorsal pair united into one, 

 there being no narrowing near the median line; annuli very pale, 

 except on the last two or three segments; last segment white basally, 

 remainder covered with a dull blackish microscopic pubescence reach- 

 ing forward to the aaal prominence, a triangular extension each side 

 of middle above, often a small spot accompanying each; respiratory 

 tube whitish, spine sometimes projecting. 



Length of pupa 9-10 millimeters, diameter 2 millimeters. Light 

 brown ferruginous, obsoletely transversely wrinkled, head and thorax 

 shining, abdomen duller. 



Antennal sheaths not very thick ,at the base, surpassing the margi- 

 nal angulation above them; carinated tubercles not prominent, lateral 

 notches broad and shallow, palpal sheaths indefinite, rather distant; 

 setiferous tubercles scarcely darker; ocellar tubercles replaced by 

 pale dots. Rima of thoracic spiracles strongly elevated from the inner 

 side, so that the top of the prominence is nearly vertical, the upper 



edge of the rimal border forming a sharp 

 carina and its anterior extremity ending 

 at the tip of the marginal extension in an 

 acute angle; the free lower edge is crossed 

 by sharp ridges, giving it a separate pro- 

 file; rima less curved at middle, more 

 strongly at each end, scarcely hooked; 

 inner notch with radiating striations. 



The abdominal fringes consist of a single 

 row of pale spines on each segment, rather 



long except dorsally on the second, where 

 



rittuitut). male, on- they are shorter and thicker. The abdomi- 

 larged to tim- diameters. nal S p iracu i ar tubercles arise from a single 

 elevation, tapering from a comparatively small base as far as the 

 middle, thence nearly cylindrical to the apex, which bears a sub- 

 circular rima; tubercle about as high as its basal diameter. Last 

 segment with six nearly equal terminal teeth, their points marking 

 the aagles of a hexagon; slender, even constricted at the base, twice 

 as long as their din meter near the base. Lateral spines almost want- 

 ing; ventral fringe in front of anal tubercle in the male; a tuft of 

 about five spines on each side in place of this in the female."
