dot on DC 3 ; some scattered blackish dots and strigulae on the rufous border; traces 

 of a dark terminal line ; fringe rufons. Hindwing concolorons, the black cell- 

 dot obsolete ; faint indications of an elongate white dot on DC 2 ; the distal border 

 about the medians shaped as on forewing, anteriorly widening so as to embrace apes 

 and distal part of costa, at abdominal margin tapering to a point opposite the origin 

 of M 2 or M 1 instead of running forward so as to touch the base of these veins. 



Underside whitish green, the borders extremely vaguely indicated in whitish 

 fleshy.

Distinguished from the rest of the albicoma group by the coloration and 

 especially by the continuous distal borders. rubescens Warr., Proc. U.S. Nat.. 

 Mus. xxx. 423 (unknown to me), may, according to the description, be similar in 

 some respects, though I am more inclined to suspect it will prove to be a 

 RacheolopJut akin to {sarptaria Möschl. ?=) ecuadorata Dogn. 



49. Chloropteryx viridicans sp. nov. 



c?, 23-24 mm. Extremely like the larger forms of albidata Warr., which 

 occurs at the same time and place. Much more strongly mixed with olive-green, 

 which becomes the prevailing colour, leaving only dots and strigulae of white ■> 

 the lines in consequence standing out less sharply; costal edge of forewing 

 in general less strongly dark-dotted (but somewhat variable in both species), on 

 the underside crimson proximally, ochreous underlined with crimson distally (in 

 albidata more or less ochreous throughout, though commonly somewhat mixed 

 with red proximally) ; hindwing with termen slightly excised anteriorly to the 

 tail at R 3 . The face in both species is ochreous more or less mixed with red,, 

 especially in upper part ; but the red appears more dominant in viridicans. 



Torne, Colombia, August 1907, type in coll. L. B. Prout. Five others entirely- 

 agreeing. 



Notwithstanding the absence of intermediates, it is just possible that this may 

 be an aberration of albidata (PMendelian), bnt the difference of shape, slight 

 though it is, warrants its being regarded as a species. M. Dognin writes me that 

 in his series of forty-eight albidata not one is of the green of viridicans, and the 

 same remark applies to the very considerable material which I have been able to 

 examine, including some in exquisite condition. 



50. Eueana eucrines sp. nov. 



S, 21 mm. Face green. Palpus moderate, third joint short ; white, above- 

 green. Vertex and antennal shaft white. Occiput narrowly green. Thorax above 

 green. Abdomen above green anteriorly, second, third, and fourth segments each 

 with a white dot at end, succeeding segments more mixed with white, anal dot and 

 underside wholly white. Legs white. 



For&wing with SC 1 from cell, anastomosing strongly with C ; emerald green,, 

 costal edge narrowly dull purplish ; discal dot mixed purplish and black ; a fine- 

 white, slightly sinuous postmedian line about 2 mm. from termen, becoming obso- 

 lescent at costa, from R 3 to hindmargin very strongly edged proximally with dull 



purplish ; fringe mixed with purplish, especially towards tornus. Hindwing with 



termen smooth ; concolorous with forewing ; two rather large, dull vinous-purple, 

 somewhat black-mixed spots proximally to middle, the larger on and just outsider
