<jorgonidia mirabilior, sp. nov. 



Primaries vermilion red, crossed from the costal margin nearly to the middle by 

 three yellow bands, narrowing inferiorly and edged with black except below ; an 

 elongated slate colored patch beyond the cell reaching the margin, sharply truncate 

 basally, its lower inner angle produced to join a large rounded similatly colored patch 

 which rests on the anal angle separated from the edge by a narrow red line and reach- 

 ing above to vein 2 and basally to near the middle of the wing. Secondaries pink- 

 ish red, vermilion on costa and internal margin. Body vermilion, ocherous tinted on 

 head and front of thorax ; posterior edge of collar pink in the middle. Posterior 

 edges of abdominal segments below narrowly white. Femora, tibiae and tarsi black, 

 lined and powdered with white. 



1 $ , Piches & Perene Vs., 2,000-3,000 feet, Peru. (Soc. Geog. 

 de Lima). Type No. 3791, U. S. Nat. Mus. 



Closely allied to Zatrephes buckleyi Druce from Ecuador, and Z. 

 garleppi Druce from Bolivia, which will also come in this genus. 



Trichromia neretina, sp. nov. 



Head dark ochre yellow on vertex, front purplish brown. Thorax purple brown; 

 abdomen bright red dorsally, pale yellov below; legs pale yellow, fore femora 

 bright red in tront, tibiae and tarsi outwardly ocherous. Fore wings purplish brown, 

 a yellow band from middle of costa to middle of outer margin, very narrow and dis- 

 located (at vein 4 ) centrally, wide on the margins and running very narrowly along 

 costa, more widely along outer margin to apex, cutting off the apical portion of the 

 ground color into a rounded spot. The ground color is darkened where it joins the 

 yellow. Secondaries straw yellow, tinted with ochre on the margins. Below as 

 above, but the dark marks fainter, the basal patch pale and diluted with pink, the 

 apical one more uniformly slaty. Expanse, 27 mm. 



i $ , Piches & Perene Vs., Peru, 2,000-3,000 feet. (Soc. Geog. 

 de Lima.) Type No. 3792, U. S. Nat. Mus. 



Very similar to Neritos repanda Walk., but entirely without the sex 

 mark. 



Trichromia and Neritos may probably be separated by the sex 

 •mark, if not otherwise ; but at present the species are mixed and I list 

 them together below. Six of the species listed by Kirby seem not con- 

 generic. I have not examined specimens, but think that amastris and 

 asana Druce, as well as cutheans Druce (described since the catalogue) 

 will fall near, if not in Bertholdia Schaus.
