166 BULLETIN 182, UNITED STATES NATIONAL MUSEUM 



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



Cuba: (Fauvel, 1863; Leng and Mutchler, 1914), Cayamas (Schwarz, iu U.S.N.M.), 

 Soledad (Darlington, in M.C.Z. and U.S.N.M.). 



Jamaica: Trinityville (Blaokwelder station 428), Spanish Town (Blackwelder 

 station 377), Milk River (Blackwelder station 415), Santa Cruz (Black- 

 welder station 421), Troy (Blackwelder station 409), Morant Bay (Black- 

 welder station 390). 



Grenada: (British Museum). 



Trinidad: Port of Spain (Blackwelder station 115), Nariva Swamp (Weber, 

 in M.C.Z. and U.S.N.M.). 



South America: Brazil (British Museum), Venezuela (Fauvel, 1863). 



Specimens exain'med. — I have examined 2 specimens in the British 

 Museum, 4 from the Museum of Comparative Zoology, 5 in the 

 United States National Museum, and 18 collected by me in 1935-37. 



Remarks. — This species evidently is somewhat variable, but the 

 West Indian examples seem to be the same as the Brazilian one in 

 the British Museum. It is therefore quite possible that Fauvel's 

 examples from "Colombia" and Cuba were the same species and that 

 it is rather widespread in tropical America. 



Fauvel's descrij^tion of the pronotal punctation differs somewhat 

 from what I have observed in these specimens. He says, "ponctua- 

 ' tion presque en ligne, bien visible et serree, egale." 



My specimens were all collected flying at dusk. 



2. NEOTROCHUS TniNITATIS, new species 



Description. — Piceous. Head with moderately small punctures 

 mixed with minute punctulae and separated by two to three times 

 their diameter; with distinct ground sculpture in front; antennal 

 segments 6 to 10 transverse; labrum twice as wide as long, rounded in 

 front; left mandible with one, and right mandible with two blunt 

 teeth on upper inner edge near apical third. Pronotum scarcely at 

 all wider than long, about one-sixth wnder than head; sides evenly 

 arcuate; widest near middle; wnth hardly a trace of basal lateral 

 impressions; disk with moderate punctures separated by one to three 

 times their diameter, and wnth a few minute punctulae; without 

 ground sculpture. Elytra one-eighth wider than pronotum, one- 

 sixteenth wider than long ; sides nearly straight ; outer apical angles 

 narrowdy rounded; coarsely coriaceous but not distinctly punctate. 

 Metasternuin not punctate. Ahdomen with very sparse moderate 

 punctures obscured by very irregular ground sculpture; eighth 

 sternite moderately lobed; ninth sternite not visible; ninth tergite 

 rounded but with blunt tubercles on each side of apex. Sexes not 

 distinguished in the present material (it appears to be all female).
