next to the last ])liite veiy .slightly emarginate behind; terminal plate 

 with its hinder maroin broadly acuminate, the tip itself rounded, and 

 with a faint median ridge extending forward a short distance. Beneath 

 slightly paler than al)ove, with rather coarser and more generally dis- 

 tributed punctures, and a few scattered hairs, most abundant on the 

 last two plates; the last plate rather l)road and evenly rounded behind, 

 possibl3' very slightly emarginate at the middle. 



Wings. — Hyaline, tinged with yellowish, the outer margins some- 

 what fuliginous, particularly beyond the end of the radial cell; every- 

 where with a violet reflection; the veins ferruginous-brown to ])rown. 

 Fore wing with the tirst recurrent vein joining the second cubital cell 

 about two-thirds of the distance from the tirst to the second transverse 

 cul)ital veins; the second and third transverse cubital veins al>out half 

 the distance apart on the radial \ ein that the second transverse cul)ital 

 and second recurrent veins are on the cubital vein; transverse median 

 vein of the hind wing almost straight, making about a right angle with 

 the median vein; discoidal vein nearly or quite interstitial; the cubital 

 vein bending slightly forward before running outward, joining the 

 transverse cubital quite obliquely and becoming obsolete beyond that 

 point; teguhe ferruginous, darker behind, with a slight yellow or 

 golden pubescent spot near the middle. 



Legs. — Coxa3 and more or less of the bases of the trochanters black, 

 also the tips, inner edges and teeth of the claws; the remainder of the 

 legs reddish ferruginous, as are the hairs and spines; fore femoi'a some- 

 what hairy, particularly beneath; fore tibia? coarsely yellowish seri- 

 ceous in front; fore metatarsi with nine long comb teeth, the first one 

 about half the length of the others, alternating with short spines: inner 

 contour of hind til)ia straight; its hind surface coarsely vellow seri- 

 ceous; tarsi of all tlie legs more or less yellowi&h sericeous. 



Length. — Females, 21-23 mm. 



Males. — l^ n known. 



1 have seen about a dozen specimens of this striking species in the 

 collection of the American Entomological Society, all females, and all 

 from Costa Kica, Cuba, and Santo Domingo. As thev agree with 

 Lepeletier's description and come from the same region there seems 

 to be little room to dou))t their identity and we mav consider Lepele- 

 tier's species as having now been rediscovered. Unfortunately the 

 name selected ))y that author was preoccupied, so it has been necessary 

 to assign it a new name. The rich color of the abdomen and legs, 

 somewhat resembling that of Chlorion IclineumoneuinfulviventriS., but 

 richer, contrasting with its silvery pubescence, makes this an extremely 

 beautiful species.
