terminal thornlike cornutus. The aedeagus lacks the ventral keel 

 found in some Theclinae and is sometimes uptm-ned distally. Harpes 

 fused for more than one-half of their lengths from base and terminally 

 truncate, or if bluntly pointed, with ends slightly upturned. Forearm 

 of gnathos often with carina along inner surface, this carina sometimes 

 laminate or dentate. 



Female genitalia with ductus bursae a simple, lightly sclerotized 

 tube, funnel-shaped at ostium bursae and with rounded or shai-ply 

 pointed lobes above and posterior to ostium bm'sae. Bursa copulatrix 

 with two large platelike signae, each ornamented with a centrally 

 placed, rose-thorn shaped spine and with anterior margm deeply 

 dentate. 



On the basis of male genitalia characters the species of Calycopis 

 are divided into five species groups. These groups are included in 

 the key and are also separately treated in the body of this paper. 



The figures w^ere drawn by the author except figures 1, 4, 6, 9, 10, 

 and 17, which were drawTi by Mrs. Amy Awl. All photographs were 

 made by Mr. Jack Scott, staff photographer, and are reproduced here 

 (figs. 35-126) twice natural size. 



Key to the Species of Calycopis 



(Unless otherwise stated, all comparisons in this key pertain to the male genitalia 

 in lateral view and to the female genitalia in ventral view.) 



Males 



1. Gnathos extending well beyond lower margin of lateral lobe of uncus; 



lower distal angle of this lobe not greatly expanded (figs. 1-9) . . 2 



Gnathos not extending beyond lower margin of lateral lobe of uncus; 



lower distal angle of this lobe greatly expanded (figs. 10-19), 



partunda group) 11 



2. (1) Lateral lobe of uncus with distal margin concave or straight; ventral 



margin of uncus concave or straight in front of lower distal angle 



(figs. 1-8) 3 



Lateral lobe of uncus with distal margin convex; ventral margin of 

 uncus convex in front of lower distal angle (fig. 9), {cecrops 

 group) 10 



3. (2) Fused harpes wide in ventral view, having a width that is more than 



two-thirds their length; distal end of aedeagus distinctly bent 

 upward (figs. 7, 8) 4 



Fused harpes more narrow in ventral view, having a width that is not 

 more than two-thirds their length, usually much less; aedeagus 

 straight or only slightly upcurved distally (figs. 1-6), (Janeirica 



group) 5 



4 (3) Aedeagus in dorsal view sharply bent distally to the right and bifur- 

 cate; gnathos with dentate carina (fig. 7), (torqueor group). 



C. torqueor 



Aedeagus in dorsal view not as above; carina laminate (fig. 8), 

 (xeneta group) C. xeneta
