along midline; with only a trace of smooth midline; with punctures 

 as on head but sometimes a little denser; without ground sculpture. 

 Elytra with punctures irregular, feebly submuricate, surface very 

 uneven though not actually rugulose; with long pubescence. Ab- 

 domen with minute and rather indistinct punctures and rather vague 

 ground sculpture. Male^ eighth sternite with a broad shallow emar- 

 gination. Female, sternites not modified. Length, 3 to 3% mm. 



Type loicality. — Trinidad, Tunapuna. 



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

 Comparative Zoology; four paratypes in the United States National 

 Museum (No. 52513) ; collected in June to September 1935 by N. A. 

 Weber. (Paratypes partly from the localities listed below.) 



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



Trinidad: Tunapuna (Weber, in M.C.Z. and U.S.N.M.), St. Augustine (Weber, 

 in M.C.Z. and U.S.N.M.), Nariva Swamp (W>ber, in M.C.Z. ), Galeota 

 Point (Weber, in M.C.Z.), Macqueripe Bay (Weber, in M.C.Z.), Balandra 

 Bay (M.C.Z.). 



Specimens examined. — I have seen only the 12 types. 



Remarks. — This species is distinct from the other West Indian 

 species by the color pattern of the elytra. It probably belongs in 

 the subgenus Medon s. str. 



I have received no record of its habits. 



5. MEDON CUBANUM, new species 



Description. — Eufous, elytra faintly picesceiit. Head a trifle 

 broader than long, the base not at all emarginate, the sides slightly 

 expanded behind the eyes and moderatel}'- rounded into base; eyes 

 small, at almost three times their lengtli from base; labrum with a 

 small median emargination about as wide as deep, without denticles ; 

 gular sutures rather close, diverging at both ends ; with rather small 

 but dense and distinctly umbilicate punctures usually separated by 

 half or less of their diameter; without ground sculpture. Pronotum 

 as wide as long, a trifle narrower than head; sides moderately con- 

 verging and rounded into base: rather coarsely canaliculate along 

 midline throughout; with some depression along midline posteriorly; 

 setigerous punctures apparently umbilicate but almost completely 

 obsolete, not den.se; without ground sculpture. Elytra with moder- 

 ately fine and dense punctures obsolescent, separated indefinitely by 

 less than their diameter; with long pubescence. Abdomen with 

 strongly umbilicate punctures fairly dense, without distinct ground 

 sculpture. Male., eighth sternite with an abrupt rounded emargina- 

 tion from one-half deeper than wide to about as wide as deep. Fe- 

 male., unknown. Length, Si/o mm.
