PSYCHE. 



[July 1S93. 



transverse lines on the primaries are ar- 

 ranged as in M. collaris. Expanse, 60 mm. 

 I have two specimens which agree thor- 

 oughly and differ in the respects mentioned 

 from the insect described and figured by 

 Moeschler. This may be merely a varietal 

 form of his species. 



Stacropus, Germ. 



155. 5. sqiiamipennis, sp. nov. £. 

 Antennae heavily pectinated, except at the 

 tip of the culmen. Front and collar very 

 dark brown ; upper side of thorax and abdo- 

 men dark brown ; lower side of body and 

 legs paler brown. Primaries dark brown 

 with a broad sooty shade crossing the wings 

 beyond the base. A narrow pale line runs 

 from the costa before the apex to the middle 

 of the outer margin. The wing is orna- 

 mented by numerous patches of raised 

 velvety scales of dark brown, margined 

 inwardly and outwardly with pale ferrugin- 

 ous. The fringes are dark brown interrupted 

 with minute white tufts at the ends of the 

 nervules. The secondaries are brown with 

 the costal area marked by three heavy trans- 

 verse bands of very dark brown. The under 

 side of the primaries and secondaries are 

 pale wood-brown with obscure and diffuse 

 transverse median bands of paler brown. 

 £xpanse 38 mm. 



LASIOCAMPIDAE. 



Stibolepis, Butl. 



156. 5. subiridescens, sp. nov. £ ■ 

 Front dark brown; collar and pectus pale 

 creamy; upper side of thorax and abdomen 

 pale fulvous ; under side of body creamy ; legs 

 creamy with the anterior pair margined inter- 

 nally with dark brown. Primaries on the 

 upper side pale fulvous crossed by waved 

 transverse basal, transverse median, trans- 

 verse limbal, and submarginal lines, which 

 are produced upon the secondaries. The trans- 

 verse limbal line is accentuated externallv 



on both wings by a series of small elongated 

 whitish spots, the most conspicuous being 

 the one nearest the apex, and those nearer 

 the inner margins of the wings. The under 

 side of the wings is uniformly very pale 

 yellowish-brown, lightest at the base. The 

 wings are semi-diaphanous. 



? . The female is much larger than the 

 male. The wings are darker reddish and the 

 median surface on the under side, which is 

 not nearly as heavily clothed with hair as in 

 the male, is most beautifully iridescent, 

 changing in different lights from pale green 

 of brilliant purple. Expanse, J , 34 mm. ; $ , 

 54 mm. 



Estigena, Moore. 



157. E. Africana, sp. nov. J. Palpi 

 dark brown ; front and upper side of body pale 

 fawn; lower side of abdomen darker brown; 

 the legs pale fawn. The primaries fawn with 

 some paler markings near the base and about 

 the middle of the wing beyond the cell. The 

 end of the cell is marked by a minute discal 

 dot. The secondaries are pale fawn on the 

 inner margin with the costa and the outer 

 margin as far as the middle darker brown. 

 There are three hyaline spots, one at the end 

 of the cell, and two just beyond it at the origin 

 of vein 7. Immediately above these spots 

 toward the costa are four pale yellowish spots 

 with dark brown nuclei. The under side of 

 both wings is marked very much as the upper 

 side. Expanse, 58 mm. 



Hypotrabala, gen. nov. 



$. Palpi minute, last joint exceedingly 

 small. Antennae relatively small with 

 minute setae. Legs short, hairy. Body 

 stout. Primaries produced at apex, the costa 

 strongly curved beyond the middle; outer 

 margin slightly crenulate, inner margin 

 curved; veins 6 and 7 stalked; vein 8 spring- 

 ing from upper angle of cell. Secondaries 

 suboval, somewhat elongated, with the outer 

 margin slightly crenulate; veins 5 and 6
