is paler, almost entirely pale yellowish testaceous with slender 

 black line along i)araclypeal suture where cnnlgera has quite a 

 wide blackish mark. The cervical shield is also paler than that 

 of crlnigera. 



Pnjia. Similar to that of crlnigera; length, 20 mm. 



Sphingidae. 

 Celerio perkinsi n. sp. 



Head and thorax olive brown, a lateral stripe on head and margins 

 of patagia whitish to ochreous. Antennae dark fuscous, apex whitish 

 except the very tip, which is fuscous. Palpi concolorous with the head, 

 paler at base. Legs greyish brown. Abdomen nearly black above, with 

 a median streak of the same color as the thorax, the posterior margins 

 of segments with fringe of white scales except in region of the median 

 streak. Thorax and abdomen below ochreous, with faint pinkish tinge. 

 Forewings dark brown, much suffused with greyish and ochreous scales 

 and hairs; lines fuscous brown, first line indistinct except near costa. 

 preceded by a triangular very dark fuscous dorsal patch ; median line 

 curved inwardly towards costa and outwardly towards dorsum ; second 

 line nearly parallel with median but closer to it dorsally, with outward 

 crenulations between the veins ; dark fuscous marks at terminations of 

 the veins ; an inwardly oblique short blackish bar at apex ; a discal 

 brownish fuscous mark and another at end of cell ; a large somewhat 

 triangular brownish patch with its base on dorsum between second line 

 and tornus ; cilia dark fuscous at ends of veins, paler between, ochreous 

 towards tornus. Hindwings very dark fuscous or nearly black, with a 

 median band of pink which is nearly obsolete towards costa, wide at 

 anal angle ; cilia ochreous. Under side of wings with a pinkish tinge, 

 most intense towards dorsum of each wing. Expanse of wings, 57-65 mm. 



Somewhat resembles zvilsoni in the pattern of the forewings, but dif- 

 fers from that species particularly in the white segmental marks on the 

 abdomen, instead of orange as in wilsoni, and the pink band on the 

 hindwing where it is orange in wilsoni. It is also of smaller size.
