*°- 36ii CALYSTRYMA FIELD 23 



159, figs, f [3], f [4]. — Comstock and Huntington, 1959, Journ. New York 

 Ent. Soc, vol. 67, p. 187. 

 Calycopis cinniana (Hewitson). — Kaye, 1914, Trans. Ent. Soc, London, 1913, 

 p. 570; 1921, Catalogue of Trinidad Lepidoptera: Rhopalocera, Mem. 

 Dept. Agric, Trinidad and Tabago, no. 2, p. 94. 



Male. — The male is said by Druce (Proc. Zool. Soc. London, 

 1907, p. 622) to differ from the female in having the costal half of 

 the uppersurface of the hindwing dark brown. I have been unable 

 to find males I could associate with the two females identified as C. 

 cinniana below. 



Female (pi. 2: figs. 17, 18). — Forewing entirely dark brown except 

 for a few blue scales on base of vein 2d A. Hindwing shining pale 

 blue, much paler in hue than in the other species of the genus and 

 with this color covering a larger area than in the other species so 

 that this wing is almost entirely pale blue except for dark brown 

 on anal lobe and for a tiny and faint marginal dark brown spot on 

 interspace Ciix and a faint bluish-white marginal line between 2d A 

 and vein Mi. Fringe at margin dark brown, outward from margin 

 bluish white. Wings below pale brown, paler than in other species 

 of the genus except C. tifla and much warmer in hue than in that 

 species. 



Length of forewing 10 mm. The smallest species in the genus. 



Female genitalia as illustrated by figure 20 with ductus bursae and 

 bursa copulatrix very short, the shortest of any species of Calystryma, 

 the combined length being only about two and one-half times the 

 width of the superior genital plate; the latter with its free edge 

 divided into two lateral elements, with posterior spurlike processes 

 lacking and anterior spurlike process greatly reduced and with the 

 posterior margin between these spurlike processes greatly produced 

 posteriorly (and thus differing from all other species of Calystryma). 



Type-locality. — "The Amazon," Brazil. 



Method of identification and location of type. — This species 

 was described by Hewitson from a single female specimen from the 

 Henley G. Smith Collection now in the British Museum (Natural 

 History). A specimen from Cayenne, French Guiana, comparing 

 favorably with the original colored illustration identified by "William 

 Schaus as C. cinniana after comparison with the type specimen, is 

 the basis for the present identification. The color and maculation of 

 both surfaces of the hindwings cannot be confused with any other 

 species. 



Distribution. — From Trinidad and French Guiana to the Amazon 

 River in Brazil. 



Trinidad: St. George County, Port of Spain (April). French Guiana: 

 Colony of Guiana, Cayenne (no date). Brazil: state?, the Amazon (no date). 



Material studied. — Two females, including their genitalia.
