Much like the following genus. Ocelli obsolete ; palpi moderate, slender, 

 obHque in our species. Primaries cleft from three-fifths (from middle accord- 

 ing to Meyrick, but not in our species) ; M^ and Cu^ stalked, connate with Cu,_, ; 

 R and R,^ stalked (very variable in bclfragci), connate or stalked with R.^; R3 

 absent; R, free in our species. Secondaries trifid, without dark scales in fringes 

 of third feather; Cu., from middle of cell, Cu^ absent. (See pi. XLVIII, fig. 4.) 



Judging by Meyrick's characterization of the genus and the struc- 

 tures of the species which we know, Psclnophorus is a very poorly 

 defined genus, intermediate between Oidaematoplionis and Aciplilia 

 and about equivalent to Adaina in the degree of its development. All 

 the species agree in having R-, stalked with one or more of the other 

 branches of the radius, wliile this vein is free in Adaina and the anas- 

 tomosis concerns R4. The venation is very variable in bclfragei. We 

 have specimens in which R.,, R^ and R5 are short stalked, others in 

 which R, and R„ are long stalked and R. separate, and still others in 

 which Ri and R, are short stalked and connate with R..

This species is so variable that no accurate description can be given, so 

 we merely call attention to the various features and point out the extent to 

 which they vary. 



The palpi are brown on the sides, white above and below. Head with 

 some white between antennae. Legs white with or without brown shading; fore 

 and middle femora and tibiae striped with dark brown. The abdomen is most 

 distinctive. It varies from pale ochreous to dark gray brown, due to a variable 

 mixture of dark scales. In the most heavily marked specimens it bears two 

 conspicuous silky white lines above, margined more or less with black dashes. 

 There are similar lines on the sides and a pair below, all less conspicuous, and 

 many black scales, especially on the sides in the posterior half of the abdomen. 

 In the paler specimens some black scales remain and the dorsal stripes are usually 

 faintly marked. 



The primaries vary from white with scattered brown and gray scales to 

 dark gray-brown with some whitish scales. The marks are very variable, anil
