By the Hon. L. W. ROTHSCHILD and K. JORDAN. 



1. Cocytius vitrinus sp. nov. 



?. Nearest to f. dupomhel Poey (1832). Upperside of body more grey, the 

 lateral border of thorax white ; uuderside of abdomen pure white, with the brown 

 mesial spots small ; side-spots of abdomen paler yellow than in C. dnponchel, as is 



also the base of the hindwing above and beneath. Forewing narrower, the hind 



angle much less prominent, outer margin convex, the greenish colour of duponchel 

 almost entirely replaced by white and grey ; the two black lines across apex of 

 cell more longitudinal, having nearly the direction of vein R' ; white stigma large, 

 kidney-sliaped, edged with brown ; all the discal lines more strongly curved in their 

 costal half, the interspace between the third and fourth lines ochraceous at the 

 veins, the fourth line almost continuous, prominent ; black streak R'— M' long, 

 extending to black submarginal cloud ; behind M' another distinct black longi- 

 tudinal streak ; at apex a white patch bordered by the black oblique apical line, 



marginal area altogether more extended white than the disc. Hindwing also 



narrower tbau in duponckel, the transparent area much larger, reaching close to 

 base and posteriorly extending nearly to snbmedian fold ; the pale yellow basal 

 patch consequently much reduced anteriorly, the portion situated in duponchel in 

 front of the sinus being almost entirely absent in ritrintis, and the sinus there- 

 fore less distinct ; black marginal border only 4 mm. broad in centre at the veins, 

 slightlv dentate between the veins. 



° On underside the yellow colour reduced. Forewing with faint pale shades 

 along the veins, and a "very slight indication of a dark band on the disc. The 

 transparent area of hindwing consists of six spaces. 



Edo-e of vaginal orifice raised anteriorly and laterally, anteriorly sinuate, 

 laterally slightl/ angulate, but not produced into a triangular lobe as in 

 C. duponchel. 



Length of forewing : 58 mm. 



One 9 from Santiago, Cuba (Tollin). 



•2. Polyptychus contraria diflfusus subsp. nov. 



S ? . Intermediate in shape of wings between /'. c. contraria from East Africa 

 and F. c. submarginalis from the western side of the continent. 



(J. Wings without any lines above and beneath. On upperside forewing with 

 fuscous fringe and a drab shadow along outer margin, this border being narrowed 

 to a point at apex of wing, gradually widening and lairly well defined from there 



to vein RS where the shadowy band is broadest. Hindwing very pule Vmff-pmk ; 



extreme edge of outer margin, not the fringes, blackish before anal angle ; near 

 this angle a minute blackish dot and a vestige of a second. 



On underside the fringe of both wings dark spotted. 



? . Forewing, on upperside with traces of two autemedian lines and a discal
