new Species of American Rhopalocera. 265 



Wc have long had specimens of this species from Mr. Bart- 

 lett's collection in our possession ; the receipt of additional 

 examples, including the female, from the Rio Napo, sent to 

 Mr. Whitely by a correspondent, induces us to describe it. 



21. Adelpha sophax. 



6. Exp. 2'1 inch. Above dark brown; primaries with 

 obsolete darker bands across the cell ; the secondaries have 

 three lighter bands parallel to the margin, and a fourth 

 straight, passing across the wing through the cell to the anal 

 angle ; a fulvous band crosses the primaries from the anal angle 

 to the costa beyond the cell. Beneath fulvous : the primaries 

 with a band corresponding to that on the upper surface silvery 

 white ; four spots in the apex and two in the cell, the basal 

 one triangular, the outer one oval ; both the latter margined 

 with black : secondaries have a dark, nearly straight band 

 crossing the wing beyond the cell to the anal angle ; the mar- 

 gins of this line are lighter ; an irregular band of silvery 

 white crosses the cell near its base, another crosses the wing 

 through the end of the cell ; there is also a submarginal row of 

 seven spots of the same colour. 



Hah. Costa Rica [H. Rogers) ; New Granada. 



Mus. nostr. 



Ohs, In the coloration of the upper surface this species 

 resembles A. tizona (Feld.). On the underside it resembles 

 A. ejnonCj Godt., from which it differs chiefly in having a 

 submarginal row of white spots on the hind wings and in the 

 coloration of the bands. 



Papilionidse. 



PlEBINM. 



22. Lejptalis Rihhei. 



$ . Exp. 1*95 in. Above dark brown ; nearly the whole 

 of the cell, and the area below the median nervure from the 

 origin of the third branch nearly to the subcostal nervure, and 

 the posterior wings except the margin diaphanous ; the 

 nervures dark ; an apical spot and a band divided in two, 

 running from the costa to the anal angle of the primaries, 

 white. Beneath — the dark markings paler ; a submarginal 

 band inside a row of six white spots on the secondaries, a 

 submarginal row of obsolete white spots on the primaries.
