tuberculate; disk with a large transverse arcuate basal impression 

 and two feeble longitudinal ones united with it and at middle with 

 each other ; with moderate punctures only slightly obscured by vague 

 ground sculpture. Elytra with moderately coarse punctures some- 

 what ol)scured by the irregular ground sculpture. Length, 2i/^ to 

 3^/^ mm. 



Type, locality. — Hispaniola, Ennery, Haiti, near an elevation of 

 1,000 feet. 



Types. — Holotype and two paratypes in the Museum of Compara- 

 tive Zoology ; three paratypes in the United States National Museum 

 (No. 52484) ; all collected by Dr. P. J. Darlington on September 

 6-11, 1934. 



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



Hispaniola: Haiti, Ennery (Darlington, in M.C.Z. and U.S.N.M.), Port-au- 

 Prince (Darlington, in M.C.Z. ). 



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



Remarks. — This species differs considerably from inipmictiis in the 

 punctation of the pronotum and elytra as well as by its very much 

 reduced antennal ridges. 



I have no record of its habits.

 abdomen castaneous. Head with two feeble depressions between the 

 antennal ridges; eyes separated from base by about one-half their 

 length. Pronotwm one-fourth wider than long; sides and angles not 

 tuberculate; sides behind middle distinctly emarginate; disk with a 

 large arcuate transverse basal impression, sometimes partially inter- 

 rupted at middle, and two short longitudinal depressions deeply united 

 to form a transverse median groove; without distinct punctures (except 

 traces at base) but with minute punctulae throughout ; without ground 

 sculpture. Elytra with moderately coarse punctures, but no distinct 

 ground sculpture. Length, 2^4 to 21/2 mm. 



Type locality. — Puerto Rico, Maricao Forest, elevation 2,000 to 

 3,000 feet.

 Zoology; four paratypes in the United States National Museum (No.

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



Puerto Kico: Maricao (Darlington, in M.C.Z. aiirl U.S.N.M.). EI Yunqne, Dar-

Specimens exanmied. — I have seen only the 10 types.
