ceals the surface. Scutellum triangular-curvilinear, and rather 

 densely clothed with short, recumbent, whitish pubescence. 



Elytra at base wider than pronotum at middle ; humeri prominent 

 and strongly elevated ; sides nearly parallel from base to apical fifth, 

 then arcuately narrowed to the tips, which are each bispinose, with 

 the sutural spine much shorter than the lateral spine ; surface moder- 

 ately convex, rather densely, coarsely punctate basally, the punctures 

 becoming obsolete toward the apices, rather densely clothed with 

 short, recumbent, whitish hairs, which do not conceal the surface; 

 each elytron with two pairs of eburneous spots, the outer spot of the 

 basal pair very small, round, and sometimes reduced to the merest 

 trace, the outer spot of median pair longer than the inner one, and 

 the two spots usually in close contact along their entire length, with 

 and obtuse, longitudinal costa at middle of each elytron, causing a 

 slight depression or channel between the costa and sutural margin, 

 and a similar depression toward the lateral margin. 



Body beneath densely clothed with long, recumbent, whitish 

 pubescence, which nearly conceals the surface, densely, finely punc- 

 tate, except the presternum, which is sparsely coarsely punctured. 

 Middle and posterior femora bispinose, with the inner spine nearly 

 twice as long as the outer one. 



FeTTiale. — Differs from the male in having the antenna only 

 slightly longer than the body, the eleventh joint not longer than 

 the tenth, and the underside of the body uniformly, finely punctured. 



Length, 14r-20 mm.; width, 4-6 mm. 



Type locality. — ^Mangrove Cay, Andros Islands. 



Other localities. — Fresh Creek, Andros Islands ; and " Bahamas." 



Type^ allotype^ and paratypes. — In American Museum of Natural 

 History. 



Paratypes.— \J.^.'^.'M. No. 43711. 



Remarks. — Described from 25 examples (one type) : The type, 

 allotype, and 21 paratypes, received from the American Museum 

 of Natural History, and collected at the type locality during May 

 and June, 1917, by William M. Mann; one paratype, collected at 

 Fresh Creek, Andros Islands, during May and June, 1917, by the 

 same collector; and one paratype labeled "Bahamas." 



This species is closely allied to stigma Olivier, but stigma can be 

 separated from it in being more elongate, the sutural margins of 

 the elytra densely clothed with conspicuous white pubescence, the 

 eburneous spots on the elytra usually longer, and with a glabrous, 

 black, longitudinal area in front of and behind each spot.
