iinibilicate punctures, intervals flat, nearly absent on middle of vertex ; 

 without ground sculpture. Pronotum scarcely narrower than head, 

 one-ninth wider than long, sides feebly converging posteriorly; less 

 coarsely umbilicately punctured than head, with an impunctate me- 

 dian band in basal half but not channeled ; without ground sculpture. 

 Elytra not distinctly punctate, surface uneven and with sparse feeble 

 setigerous tubercles; without ground sculpture. Abdomen exceed- 

 ingly finely but not densely punctate, with fine long pubescence; with 

 indistinct transverse ground sculpture. Male^ seventh sternite not 

 modified; eighth with a moderately deep rounded emargination. 

 Female, sternites not modified. Length, 3 to ^V-}, mm. 



Tijpe locality. — Colombia. 



Types. — Either in the Hope Museum, Oxford, or the Zoologische 

 Museum, Berlin. 



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



Grenada: (Cameron collection, British Museum; United States National 

 Museum). 



Trinidad: (Bernhauer and Schubert, 1912; I^eng and Mutchler, 1914), Tacarigua 

 (Blackwelder station 107C). 



South America: Venezuela (Bernhauer and Schubert, 1912), Cot-ombia (Erich- 

 son, 1840; Bernhauer and Schubert, 1912). 



Specimens examined. — I have seen 27 examples in the British Mu- 

 seum, 7 in the collection of Dr. Cameron, and 1 collected by me in 

 December 1935. (All these are from the West Indies.) 



Remarks. — Although I have seen no specimens from Colombia or 

 Venezuela, I believe this identification to be correct. It is distin- 

 guished by the absence of ground sculpture and the absence of a 

 median pronotal channel. It belongs in the subgenus Sunius s. str. 



My specimen was taken from under moss and earth on a rock.

 distinctly emarginatc only above the neck; eyes very large, separated 

 from base by about half their length ; sides rounded into base ; labrum 

 with a small median emargination but no denticles; gular sutures 

 moderately separated, most approximate before middle, thence feebly 

 diverging; with coarse, distinct, and crowded umbilicate punctures, 

 the intervals convex and without sculpture. Pronotmn about one- 

 seventh wider than long, the sides moderately converging posteriorly 

 and rounded into base ; without any punctures or distinct ground sculp- 

 ture but with fine rounded tuberculi separated by one to two times 

 their diameter; middle stripe irregular but smooth, not elevated. 

 Elytra about as long as wide, about one-eighth wider than pronotum ; 

 surface very uneven, without distinct punctures but with somewhat
