The body is long, thick and fusiform. The head large, prominent and broad; 

 front nearly vertical, flattened, and smooth ; eyes large and salient ; palpi smooth, 

 stout and closely applied to the front ; tongue extends to the end of the third abdo- 

 minal segment ; antennae rather short, not as long as the thorax, minutely ciliferous, 

 fusiform and ending in an angular hook with seta. The thorax is crested in front, 

 long from the base of anterior wings to the head, and rounded in front. The abdomen 

 is oblanceolate, slightly more than twice longer than the thorax, and sparingly tufted 

 at the apex. The legs are slender, the anterior and middle smooth, the posterior 

 with femora and tibiae pilose, with two short and two moderately long spurs. The 

 anterior wings are very oblique, length much less than that of the body, and some- 

 what more than twice longer than broad across the inner angle ; the posterior margin 

 truncate at the tip, obtusely angulated opposite medio-superior nervule, excavated 

 from post-apical to superior, and thence excavated and slightly wavy to the inner 

 angle, which is hooked ; inner margin deeply concave. Posterior wings rounded at 

 tip ; hind margin doubly excavated from the medio-central to inner angle, which is 

 acute. 



Larva. — Head rather small ; body tapers anteriorly, and is wrinkled transversely, 

 with a long, straight, caudal horn. Pupa rather slender ; head case obtuse ; tongue- 

 case not apparent. The larval transformation is subterranean.

 Head, palpi, thorax and abdomen brown, with an obscure purplish or reddish hue; palpi beneath pale 

 reddish brown. Abdomen with an indistinct double row of dorsal, dark brownish spots; beneath as well as 

 the thorax, pale rufescent brown, with a tawny line in the middle of ventral surface; yellow lateral dots on the 

 hind portions of the segments, and a small lateral, pale yellow pencil of hairs at the base of the first 

 segment. Anterior wings brown, with a rufous tinge in the middle and toward the tip ; an oblique, pale 

 brown line before discal spot, beginning near the origin of subcosto-inferior vein, margined on each side 

 with darker brown; discal spot blackish, edged with pale brown ; a broad, dark brown, subterminal shade, 

 extending from post-apical vein to the hind margin, and bordered anteriorly by a curved, pale brown line ; 

 a ferruginous brown spot in apical interspace, with its basal portion and the middle of the next interspace 

 pale reddish hue and three indistinct brownish lines crossing the nervules. Posterior wings brownish, 

 deepening toward terminal margin, with indistinct lines above the inner angle, and dark brown marginal 

 spots at the inner angle and on the ends of medio-posterior and central veins.
