 brane; the latter bearing an opposing pair of long, dense, very dark 

 spine combs; spines numerous and moderately stout; lateral margins 

 of ventral plate concave. Aedeagus slender, very slightly tapering; 

 fused manica sclerotized for a short distance; otherwise simple.

I am indebted to Mr. Tarns for the identification of this species. 

 He sent me a description and a photograph of the genitalia of 

 Walker's type (a female) and compared a slide and a specimen I 

 submitted. jNIoschler's species we know only from his description, 

 but that leaves little doubt as to what he had before him. He says 

 that the fore wing is "gelblich angehauctes Weiss." This (since 

 his type is a female) could apply only to the female of fhicteUa. 

 Hampson's JwlophaealL'^ I associate on the evidence of distribution 

 and a female of tinctellu in the National Museum collection, which 

 matches in color the paler fu.scous males of Iwlophaeolis. Dyar 

 established the synonymy of holophaealis and miicolor. I have 

 examined the genitalia of the Barnes and McDunnough type. 



The species is extremely variable in color and venation and nor- 

 mally the males and females are sharply contrasted, the nuiles being 

 brownish ocherous and the females white. But this dimorphism 

 is not constant. I have before me two males from Argentina 

 (British Museum collection) that are almost pure white and not to 

 be distinguished from the other wdiite species except l)y genitalia. 

 We have also one pale brown female from French Guiana. The 

 genital characters are constant.
