3. Calystryma blora, new species 



Figure 3; Plates 1 (figs. 5, 6), 2 (figs. 5, 6) 



Male (pi. 1 : figs. 5, 6). — Very similar to C. keta in maculation, with 

 ground color of wings above dark brown and with white marginal line 

 on hindwing absent or greatly reduced (sometimes indicated by a few 

 scattered white scales). Wings underneath as in C. keta with a pale 

 gray ground color and with two marginal ocular markings, one each 

 in interspaces M 3 and Cu^ the latter being distinctly larger. On the 

 hindwing, on this surface, the orange red is more indistinct on the 

 inner side of the postmedian tripartite line in interspace Cui than in 

 C. keta. Other markings quite like those of C. keta. 



Length of forewing 11.5-12.5 mm. 



Male genitalia as illustrated by figures 3b-e with harpes fused only 

 at base; with aedeagus slightly curved upward at distal end about as 

 in C. keta; with gnathal arm distally acute and having a carina past 

 the middle near the distal end; with lateral lobe of uncus having a 

 downward directed beaklike posterior projection and with a minimal 

 projection on lower margin. Eighth tergite (fig. 3a) subcordate in 

 shape, shallowly incised along posterior margin, distinctly elongated 

 anteriorly and with posterior lobes blunt. Easily separated from C. 

 keta by the shape of the gnathal arm, of the lateral lobe of uncus, and 

 of the eighth tergite. 



Female (pi. 2: figs. 5, 6). — Forewing above quite like that of C. 

 keta. Hindwing similar to that of C. keta with blue more extensive 

 in anal area, the dark brown being restricted to the outer border and 

 anal veins. Red spot on anal lobe present but very faint. Wings 

 underneath very similar to those of the male, differing only in having 

 smaller marginal ocular markings with correspondingly smaller black 

 centers. 



Length of forewing 12 mm. 



Female genitalia unknown as the abdomen of the sole specimen 

 is missing.
