harpes; lateral element of uncus with distal margin concave just 

 before upper distal angle, which is greatly produced in lateral view, 

 almost spurlike, and with lower margin nearly straight, or only slightly 

 concave; lower distal angle of imcus only slightly rounded; arm of 

 gnathos with a small ridgelike carina on inner surface; apices of 

 harpes in lateral view slightly pointed and in ventral vievv^ close 

 together. Eighth tergite (fig. 216) most Hke C. bactra in shape with 

 posterior concavity very shallow. 



Female (figs. 123, 124).— Wings above dark brown with a shght 

 dull purplish-blue sheen in base of hindwing. Wings below Uke the 

 male except that the ground color is lighter. 



Length of fore wing 12 mm. 



Female genitaUa, as illustrated by figure 33, with combined length 

 of ductus bursae and bursa copulatrix less than two and one-half times 

 the width of ostium bursae and with a pair of prominent spurlike teeth 

 on posterior ostium bursae lobes; ductus seminalis near middle of 

 combined ductus bursae and bursa copulatrix. 



Type-locality.— "Chapada Campo," = Plain near Serra da Chapa- 

 da, "Brazil." 



Additional type data. — ^Originally described from a single male, 

 the holotype (locality as given above; H. H. Smith; British Museum 

 (Natural History) type No. Rh. 901; genitalia preparation number 

 NHB 1951-485). This holotype was compared by Mr. D. S. Fletcher 

 with a specimen from Mato Grosso, Brazil and found to be conspecific. 

 This compared specimen is the basis for the identification of the name 

 indigo in this paper and is the one illustrated in figures 16, 216, 105, 

 and 106. 



Distribution. — ^Brazil and Argentina. 



Brazil: State of Mato Grosso, Serra da Chapada (January); State ?, Amazon* 

 Argentina: Territory of Misiones, Puerto Aquirre. 



Material studied. — 'Two males and two females, including their 

 genitalia.

Male (figs. 101, 102). — Wings above with dark border sHghtly 

 broader than in indigo but not nearly as broad as in C. partunda.
