N0 - 3611 CALYSTRYMA — FIELD 13 



the same species as the lectotype and, through the courtesy of A. G. 

 Gabriel, it was sent to me for study. The genitalia of this specimen 

 (illustrated in the present paper by figure 5) together with the photo- 

 graph of the lectotype (herein illustrated by figures 3 and 4 on plate 3) 

 is the basis for the present identification. 



Distribution. — Known only from two widely spearated areas, 

 Dutch Guiana and Peru. 



Dutch Guiana: (no specific locality, Fruhsterfer Collection). Peru: Depart- 

 ment of Loreto, Iquitos (6036 ft., October). Rio Morona (6203 ft., August). 



Material studied. — Two males and one female, including their 

 genitalia. [Note: The male specimen from Peru is slightly larger 

 and more clearly dull metallic purple, particularly on the forewing, 

 than the one studied from Dutch Guiana. Underneath it has the red 

 markings slightly darker. The eighth tergite and the genitalia of this 

 specimen are somewhat larger. Otherwise it is entirely like the Dutch 

 Guiana specimen.]

Male (pi. 1: fig. 9).- — Wings above entirely dark brown, not 

 distinguishable from C. keta except that the white submarginal line 

 on hindwing below vein M 3 is very faint. Wings underneath light 

 brown in color as in C. atrox and C. maka and as in the former with 

 only a single red marginal ocular marking on hindwing. It differs 

 from C. atrox in having the black pupil in the center of this ocular 

 marking only slightly smaller and in having slightly more red along 

 inner side of postmedian tripartite line on hindwing. 



Length of forewing 13 mm. 



Male genitalia as illustrated by figures 6b, c with harpe fused only at 

 base, short and bluntly rounded distally with a small nipple-like 

 projection from dorsal margin at distal end, this projection acute and 

 inwardly directed; aedeagus broadly curved upward throughout the 

 distal three-fourths of its length; gnathal arm distally acute and 

 lacking a carina; with lateral lobe of uncus greatly projected posteriorly 

 into a large, blunt, beaklike lobe and with a minimal projection on 

 lower margin. Eighth tergite (fig. 6a) a simple plate, shallowly 

 incised along posterior margin and with anterior and posterior margins 

 nearly parallel.
