tribution, occupying a range between those of the splendens-lelae and 

 the paraguayensis-robertae segregates. 



Remarks : There are several reasons for questioning the determina- 

 tion that the species treated is actually extensa. First, the type is 

 officially imavailable to me and no illustration of it exists. Second, 

 I have not seen any examples of this genus from Peru and I do not 

 know of the existence of other museum specimens. Peruvian ento- 

 mologists were unable to supply examples. Third, there is a question 

 about the type locality. There are at least three populated places 

 named Huaj^abamba in Peru. Two are in the northern part of San 

 Martin and Cajamarca. The other is in the southern part of Cusco. 

 In the original description the abbreviation "or." follows the type lo- 

 cality. I presume it refers to the Spanish word, oriente, meaning east. 

 All three Peruvian localities named Huayabamba are on the eastern 

 side of the Andes, but the one in Cusco is at least 5° east of the other two 

 and it is much nearer to the known range of the species I am identifying 

 as extensa in this paper. An examination of the genitalia of the type 

 would verify whether the name extensa is correctly applied. 



Method of determination: This species has been determined as 

 extensa by comparison with the original description, especially the re- 

 marks on the maculation of the hindwing. It is true that the macula- 

 tion of that wing does vary to some extent in the other species of the 

 complex and therefore, the character alone is not completely reliable; 

 but considering our total knowledge of the complex, I believe the name 

 is correctly applied. 



Eusceptis robertae, new species 



Figures 9, 10, 31, 32 

 Structure, vestiture, and coloration of head, thorax, and abdomen as 

 in splendens. Coloration of legs also similar except base of tibia of 

 foreleg as dark as apical part, other two pah-s of legs with dark areas 

 reduced, femora nearly completely white, tibia of middle leg with 

 smaller tufts. Pattern of maculation of forewing differing from that 

 of splendens in that the basal parts of the two ocellate spots form a 

 sinuous line, the two basal transverse lines are darker than the broad 

 costal spot and the oblique subterminal bar, the oblique subterminal 

 bar usually obsolescent in the middle, and the fringe uniformly dark. 

 Ventral surface of forewing of male mostly yellowish orange with two 

 black costal spots, basal part only of oblique subterminal bar usually 

 present, entirely absent in some specimens. Ventral surface of fore- 

 wing of female with more dark markings than male, oblique subter- 

 minal bar divided into two spots or with apex and basal parts darker 

 than median area. Hindwings of male yellowish orange, lacking dark 

 marks on both surfaces. Position and shape of dark marks on dorsal
