NO. 3552 GENUS CALYCOPIS — ^FIELD 21 



in the collection of the British Museum (Natural History) can be 

 positively identified as belonging to the original series. The male 

 labeled BM type no. Rh. 913 with the abdomen lacking is hereby 

 designated the lectotype. Mr. D. S. Fletcher of that institution 

 kindly compared it with a male from Irazii, Costa Rica (near the 

 type locality) and this male is the basis for the identification of 

 C. isoheon in the present work. The female type was dissected and 

 studied by Mr. Fletcher and is the female of quite another species 

 not belonging in the genus Calycopis.

 into Panama.

Material studied. — Sixty-four males and 51 females including 

 the genitalia of 32 males and 29 females. 



The partunda Group 



Uncus in lateral view with lower angle greatly produced and mth 

 ventral margin greater than, equaling, or nearly equaling length of 

 distal margin. Aedeagus fairly straight, ending distaUy in a straight 

 or upward projected point. One species {C. vibulena), with genitalia 

 characters somewhat resembling C. torqueor (see the torqueor 

 group), has the aedeagus sharply curved to the right (in dorsal view) 

 but with the distal end of aedeagus not bifurcate and also with an 

 uncus tj'pical of the partunda group. 



Calycopis susanna, new species 



Figures 10, 20^, 21e-g, 27, 83-90 

 Male (figs. 83-86). — Wings above indistinguishable from C. 

 isoheon. Undersurfaces of mngs of some specimens indistinguishable 

 from C. isoheon but usually with red of tricolored postmedian band on 

 forewing a little less distinct. Specimens found in the northern part 

 of the range (Mexico to Costa Rica) tend to have a second submarginal 

 black pupillated red spot on the hindwing below; however, this also 

 occurs in some southern specimens.
