NO. 3552 GENUS CALYCOPIS — FIELD 9 



Location of types. — Holotype in United States National Museum, 

 paratypes in the collection of Lt. Colonel Stanley S. Nicolay. 

 Distribution. — Known only from the type-locality. 

 Material studied. — Three males including their genitalia. 



Calycopis caulonia (Hewitson), new combination 



Figures 3, 20c, 23, 55, 56, 115, 116 



Thecla caulonia Hewitson, 1877, Illustrations of diurnal Lepidoptera: Lycaenidae, 

 vol. 1, p. 188; vol. 2, pi. 75, figs. (?) 587, 588. 



Male (figs. 115, 116). — Very similar to bactra except that post- 

 median band on undersurfaces of wings contains less red along inner 

 side and the bars at the end of the cell in both wings on this surface 

 are separated by a greater distance from the postmedian bands. Very 

 close to janeirica in this sex, hardly differing except in size. 



Length of forewiug 10-12 mm. 



Male genitaha, as illustrated by figm-e 3, with aedeagus short as in 

 bactra, being about 3 mm. in length, straight, not uptiu'ned distally 

 and with distal end not prolonged as it is in bactra and not blunt as 

 it is in janeirica; harpes and uncus about Uke janeirica but smaller. 

 Eighth tergite (fig. 20c) similar to janeirica but with posterior con- 

 cavity more narrow and proportionately deeper. 



Female. — Close to females of bactra, differing chiefly in having the 

 blue on hindwing more restricted, being nearly absent in interspaces 

 Mi and M2 opposite the end of cell. Wings below as in male with 

 slightly less red along inner side of postmedian band and with cell bars 

 further from this band than in bactra. 



Length of forewing 10.5-11.5 mm. 



Female genitalia, as illustrated by figure 23, with posterior ostium 

 bursae lobes smaller and with spurs much closer together and nearer 

 center of upper margin of ostium bursae than in bactra', with ductus 

 bursae cm^ving to left before entrance of ductus seminaUs and with 

 sclerotized area around opening of ductus seminaHs (in bactra the area 

 is nonsclerotized and the ductus biu-sae strongly and abruptly curved 

 ventrally before nonsclerotized area). 



Type-locality. — "Rio Janeiro" [Rio de Janeiro, Brazil]. 



Additional type data. — Caulonia was originally described from a 

 single female specimen, the holotype, W. C. Hewitson collection, now 

 in the collection of the British Museum (Natural History) and is 

 labeled type number Rh. 916. According to Mr. D. S. Fletcher of 

 the staff of that institution, this type lacks its abdomen. Another 

 specimen, a topotype, was carefully compared with the holotype by 

 Mr. Fletcher and upon being identified as that species was loaned to 

 me for study. This specimen is the one illustrated in figures 23, 55, 56.
