posterior angles of the prothorax more distinct, and the 
color darker. The genus has not been known before from 
the West Indies. 
116. Pentagonica flavipes (Lee.) 
117. Pentagonica nigricornis n. sp. 
bicolor (Gundlach) (Rhombodera) , not Lee. 
Form as usual in Pentagonica ; surface alutaceous, slightly 
shining; black; entire prothorax, narrow reflexed margins 
of elytra, and legs yellow; palpi brown; antennae entirely 
black. Prothorax slightly wider than in flavipes, eight 
or nine tenths wider than long. Elytra moderately striate, 
striae irregularly subpunctate; intervals slightly convex. 
Length ±4-5 mm. 
Holotype (Museum of Comparative Zoology no. 19537) 
and 2 paratypes from Soledad (near Cienfuegos) Cuba, 
Nov. 1 & 2 ; all from flood debris. 
This differs from all previously described New World 
Pentagonica in type of coloration combined with uniformly 
black antennae. It resembles picticornis Bates of Guatemala 
except that the antennae (of nigricornis) are not bicolored 
and there is less yellow on the lateral margins of the elytra. 
Gundlach’s notes under “Rhombodera bicolor” show that he 
really had this species before him.
