PSYCHE. 



[May 1893. 



disposition of the light spaces just before the 

 apex between the spot at the end of the cell 

 and the submarginal line is such as to rudely 

 indicate the outline of a St. Andrew's cross. 

 In some specimens this is more distinct than 

 in others. The secondaries are uniformly 

 testaceous, the fringes checkered as on the 

 primaries. The under side is obscure testa- 

 ceous with faint suggestions of discal dots 

 and submarginal lines on both wings. The 

 fringes are as on the upper side. 



§ . The female is much larger than the 

 male, and on the under side with the discal 

 dots and transverse lines quite distinct. Ex- 

 panse, $ , 40 mm. ; $ , 55 mm. 



107. O. (?) ocelli/era, sp. nov. $. An- 

 tennae, palpi, front, collar, and upper side of 

 thorax rich brown. Under side of thorax 

 and abdomen lighter. Legs brown, mar- 

 gined internally with lighter. Tarsi black- 

 ish. On the dorsal line of the abdomen 

 there are four high tufts of dark brown hair. 

 The primaries are rich brown for one-third of 

 the distance from the base, then bluish gray; 

 this bluish-gray area is separated from the 

 outer half of the wings by a curved white 

 line, running from before the apex on the 

 costa with a semi-circular sweep to the outer 

 angle, denned externally by a narrow 

 brown line, succeeded by a narrow light 

 brown line, the space beyond these lines be- 

 ing of the same color as the base and inter- 

 rupted by a zigzag limbal and submarginal 

 line of dark brown. The apex is marked by 

 a zigzag white line, shaded internally with 

 darker brown. The fringes are brown, 

 broadly checkered with blackish. The sec- 

 ondaries are uniformly pale brown. The 

 fringes uniformly pale fawn. On the under 

 side, the wings are fawn with the primaries 

 clouded with fuliginous near the base and at 

 the apex, and the secondaries have obscure 

 transverse limbal and submarginal brown 

 lines. 



$ . The female is much as the male, but 

 larger. The antennae not quite so heavily 

 pectinated. Expanse, $ , 30 mm. ; $ , 40 mm. 



108. O. (?) tkersites, sp. nov. £ . Body 

 uniformly blackish-brown. Primaries obscure 

 brown with blackish shades at the base and 

 beyond the end of the cell. At the end of the 

 cell there is a dark brown spot. There is an 

 irregular submarginal narrow line, and also 

 a dark marginal line. The fringes are pale 

 brown checkered with darker brown. The 

 secondaries are uniformly sooty. The fringes 

 are as on the primaries. The under side of 

 both wings is pale brown clouded with fuli- 

 ginous in the region of the cell on the prim- 

 aries. On the secondaries there is an obscure 

 discal dot. Expanse, 38 mm. 



Note. — I refer these three species to my 

 genus Oecura without any knowledge of their 

 larval habits. Structurally they agree thor- 

 oughly with O. goodit, mihi, save that the 

 tufts of hairs upon the dorsal line of the abdo- 

 men are more conspicuous than in that 

 species. 



Thamnocera,* gen. nov. 



Allied to the foregoing genera, from which 

 it is not distinguishable so far as the neura- 

 tion is concerned, but from which it is dis- 

 tinguished by the structure of the antennae, 

 which in the male are relatively much longer 

 than in Oecura and Notohyba, and in the 

 female are not nearly so strongly pectinated, 

 as in those genera, the pectinations being 

 quite minute in the latter sex. Furthermore, 

 the tufts, which appear on the dorsal line of 

 the abdomen in Notohyba and Oecura, in 

 Thamnocera are lacking, or obsolescent. 

 The legs have the tibiae at their extremities 

 evenly enlarged, but not tumid as in Noto- 

 hyba. They are sparsely clothed with hair 

 and are armed as in Notohyba with two pairs 

 of spurs upon the hind legs. The primaries 

 are subtriangular, somewhat more elongate 

 than in Notohyba, but otherwise very much 

 the same. Type T. albilinea, Holl.
