description (Gacde, 1936). As shown in the photograph of the male 

 (fig. 37), the head and the right hindwing are now missing. 



This species obviously is related closely to the other three members 

 of Animula. Certain important divergences, however, have made it 

 necessary to erect a new subgenus for this insect. The more impor- 

 tant of these differences, demonstrated by A. seitzi, is the absence 

 of tibial spurs and certain venation al characters in the forewings 

 (e.g., relative position of M2+3) and perhaps also in the secondaries, 

 but a cleared preparation of the latter will have to be examined 

 before a conclusion can be drawn.

Type of genus.^ — Thanatopsyche apicalis Hampson, 1904. Orig- 

 inal designation and monobasic. 



Male. — Antennae (fig. 381) broadly bipectinate at lower half, 

 tapering gradually outward, becoming serrate for outer third or 

 fourth of length; segments numerous (over 30), very short, pectina- 

 tions arising for most part mesad, becoming apical for distal third 

 of antenna. Thorax clothed with dense, wooly hair. Epiphysis 

 (fig. 183) present on foretibia, K or more length of tibia. Meso- and 

 mctathoracic tibiae each with single apical spur. 



Wings (fig. 166) mostly transparent with greater or lesser concen- 

 tration of scales along costal and hind margins of wings, frequently 

 along veins. Primaries elongate, 12-veincd; II3 and 4 variously 

 stalked, rarely completely fused; intercalary cell absent from both 

 wings; base of lA usually atrophied, curving abruptly down, connec- 

 ting with 2A halfway out along hindmargin, usually sending short, 

 faint spur toward outer margin; 2 A and 3 A separate at base with 3A 

 joining 2A, separating as short spur toward hindmargin. Secondaries 

 approximately half size of primaries, triangular, either 7- or 8-veined 

 because of variation in union of M2 and 3; Sc+Ri and Rs converging 

 at point beyond apex of cell, immediately separatmg again; M2 

 and M3 stalked or fused throughout length. 



Male genitalia. — Tegumen with shallow apical notch. Valves 

 with pulvilli slightly developed, sparsely spinulose; apex of sacculus 

 minutely toothed. Vinculum abruptly narrowing to elongate saccus. 

 Aedeagus with membranous, bulbous basal expansion. Eighth
