NORTH AMERrCAN LEPIDOPTI^RA. 87 



niarginul spots in lytrea are smaller, fainter and internally edged 

 with black, while in Dominica they are plain. The transverse line 

 on the superiors o^ Dominica starts from the costa, and in lytrea from 

 the white band. The principal differences on the inferiors are the 

 longer and very much narrower white band in Dominica, and the 

 heavy black inner lining of the crescents and the darker black of 

 lytrea. The hind wings of lytrea have distinct pointed tails. The 

 two species also vary considerably beneath, but the differences given 

 are all sufficient to separate them. 



Described from five specimens, four males and one female. Two 

 wei-e caught at Samana Bay, by Dr. W. L. Abbott, and are in the 

 collection of the Am. Ent. Soc. Two were presented to me by my 

 friend, Mr. E. M. Aaron, and one received from Mr. A. G. Weeks, 

 Jr. ; all are from Hayti. 



Myscelia Streckeri nov. sp. 



The male expands two and one-eighth inches and the female two 

 and a half inches. The superior wings are of a rich black with a 

 purplish cast, a broken line of bluish purple marginal dots run very 

 close to the exterior margin. There are three white apical spots 

 surrounded by the same heliotrope color ; running from the base for 

 about one-quarter inch into the discoidal cell are two of heliotrope 

 or purple-blue ; starting from the base is a large blotch of the same 

 color extending into the wing for nearly one-half inch. The inferior 

 wings are emarginate and of the same ct)lor as the superiors only 

 somewhat lighter, and have the same marginal spots with a faint 

 indication of a submai'ginal band. There is a heliotrope blotch on 

 the inferiors similar to that on the superiors ; the underside of the 

 inferiors and the apices of the superiors on the underside look very 

 much like the underside of the inferiors of Pyrameis atalanta, and I 

 think cannot be described in words. 



The 9 is larger, lighter in color, and in addition to the three apical 

 spots has two on the wing near the centre of the costa, and three 

 which are submarginal. The three apical spots are not surrounded 

 by heliotrope color as in the male, and the others are plain white. 

 The underside is the same as in the male. 



Described from five specimens from Lower California through the 

 kindness of Mr. A. G. Weeks, Jr. 



I take pleasure in dedicating this species to my friend. Dr. Herman 

 rttrecker.
