20 Mr. T. D. A. Cockerell — Descriptions and 



face narrower, not excavated ; clypeus light except a broad 

 black stripe down each side, and linear apical margin; supra- 

 clypeal light mark emarginate above, shaped rather like the 

 hoof of a deer ; lateral marks long and narrow, ending in a 

 point above, at about level of lower side of middle ocellus ; 

 labrum with a large light patch and a dot on each side of it ; 

 mandibles dark ; scape black, rather thick but not swollen ; 

 flagellum obscurely brownish beneath toward the end ; as in 

 percrassa, the prothorax has two light marks above (but they 

 are shorter), the tubercles are largely light (the light area, 

 however, notched behind), and the tegulse have a light spot, 

 but there is no light spot behind tubercles ; ocelli much 

 smaller and in a triangle (large and in a curved line in per- 

 crassa) ; mesothorax shining, with well separated punctures 

 (more densely punctured in percrassa) ; axillae and post- 

 scutellum wholly black, but scutellum with a broad median 

 creamy-white band, narrowing posteriorly ; area of meta- 

 thorax larger than in percrassa, with a very prominent trans- 

 verse ridge. Apical half of wings distinctly smoky ; nervures 

 strong and dark ; b. n. meeting t.-m. (tailing short of it in 

 percrassa); first r. n. entering second s.m. very near base (at 

 least twice as far from base in percrassa) ; second r. n. going 

 beyond end of second s.m. (entering it near end in percrassa). 

 Hind spurs strongly curved (longer and little curved in per- 

 crassa). Second abdominal segment very sparsely punctured 

 on disk, its extreme base with appressed white hair ; ventral 

 surface of thorax with much white hair; second ventral 

 segment of abdomen covered with white hair, the following 

 ones with dark fuscous or black. The type specimen carries 

 several pollen-bodies of an Asclepiad attached to its mouth. 

 ? . — Similar to the male, with the same peculiar venation 

 face broader, the markings reduced to three linear stripes, 

 the supraclypear mark broader than upper part of clypeal 

 stripe ; prothorax with a pair of cuneiform white marks 

 above ; tubercles black, with a variable small light spot ; 

 tegulas with a hardly perceptible spot ; scutellar mark reduced 

 to a small triangle on anterior middle. The legs are black 

 without light markings, whereas in the male the anterior and 

 middle femora have large light marks, the anterior tibiae are 

 light in front, and the other tibiae carry apical and basal spots.
