MONOGRAPH OF WEST INDIAN STAPHYLLNIDAE 517 



5. COPROPORUS WEBERI, new specieg 



Description. — Dark rufopiceous, head black, apex of abdomen 

 rufous; sometimes rufous throughout. Head not punctate, but with 

 a few minute punctulae obscured by the distinct transverse strigulae. 

 Pronotum with punctulae and sculi)ture as on head, sometimes obso- 

 lescent. Elytra rather flattened at sides but not distmctly concave, 

 except for a narrow stria along the margin ; with very minute punc- 

 tulae and irregular transverse strigulae. Abdomen with small punc- 

 tures much obscured by irregular strigulose sculpture. Male^ eighth 

 sternite with an equilateral triangular emargination, the angles pro- 

 longed as parallel ridges, bearing coarse setae at the apices; eighth 

 tergite quadridentate, the processes of same shape, size, and separa- 

 tion, the middle pair more posterior. Female., eighth tergite with 

 four slender lobes, equally separated though middle pair not so 

 deeply, middle pair a little more slender and longer. Length, 

 21/^ mm. 



Type locality. — Trinidad, St. Augustine. 



Types. — Holotype, male, and seven paratypes, in the Museum of 

 Comparative Zoology; six paratypes in the United States National 

 Museum (No. 52542) ; collected in July 1935 by N. A. Weber. 



Records. — The following are the records known to me : 



Trinidad: Maracas Falls (Weber, in M.C.Z.), St. Augustine (Weber, in M.C.Z. 

 and U.S.N.M.), foothills north of Tunapuna (Weber, in M.C.Z. and 

 U.S.N.M.). 



Specimens examined. — I have seen only the 14 types. 



Remarks. — This species is very distinct by the strong strigulae of 

 all parts of the dorsal surface. All others of our species having these 

 strigulae throughout have the elytra concave at the sides. 



The strigulae are sometimes fainter on the pronotum but those on 

 the elytra are enough to distinguish the species. The flattening at 

 the sides of the elytra may at times seem to attain convexity. In 

 these cases the specimens would key out to -flavicolJis and cacao. 

 From the former it is distinguished by its dark pronotum; from the 

 later by its size and the sparse strigulae of the pronotum. 



I have received no record of the habits of this species. 



6. COPROPORUS CACAO, new species 



Desciiption. — Piceous, sometimes slightly rufescent (or even testa- 

 ceous). Head not punctate but exceedingly minutely punctulate and 

 with scarcely a trace of strigulae. Pronotum not distinctly punctate 

 but minutely punctulate, without strigulae (although iridescent). 

 Elytra with a lateral concavity formed principally by the broadly 

 upturned margin; not distinctly punctate but with punctulae dis- 

 tinct; sometimes at lateral third and along apical margin with fine
