360 BULLETIN 182, UNITED STATES NATIONAL MUSEUM 



Records. — The following is the only record known to me : 

 Cuba: Sierra del Rosario (Bierlg, 1938; Bierig, in Blacliwelder collection). 



Specimens examined. — I have seen only one example in my own col- 

 lection, received from Sr. Bierig some years ago under the name 

 truncata. 



Remarks. — This species is very similar to dentatus but seems to be 

 distinct. It can apparently be recognized by its small size and palo 

 color as well as by the reduced elytra. 



I find no record of its habits. 



5. STILIPHACIS DARLINGTONI, new species 



Description. — Castaneous, somewhat picescent especially in front, 

 elytra paler. Head ovate, wider than tlie elytra ; eyes prominent, at 

 one-hall" more than their length from base ; sides completely rounded 

 into base which is emarginate above the neck ; labrum with two slender 

 teeth a little longer than distance between them, flanked by a pair of 

 small denticles; with moderately large and dense umbilicate punctures, 

 frequently united in short irregular channels ; without ground sculp- 

 ture on the intervals. Pronotum »ne-third longer than wide, widest 

 at middle, sides behind nearly straight, basal angles moderately 

 rounded ; sides indistinctly tuberculate ; punctures as on head but not 

 as flat-bottomed, only occasionally united; witliout ground sculpture. 

 Elytra barely wider than long, seven-eighths as long as pronotum, nar- 

 rower than abdomen or head ; with rather coarse impressed punctures 

 separated by feebly convex intervals; without distinct ground sculp- 

 ture. Abdomen with coarse punctures basal ly on each segment, be- 

 coming finer toward apex. Male., eighth stern itc truncate. Female., 

 eighth sternite prominently rounded. Length, 2l^ to 3 mm. 



Type locality. — Jamaica, main range of the Blue Mountains, eleva- 

 tion 5,000 to 7,388 feet. 



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

 Comparative Zoology; six paratypes in the United States National 

 Museum (No. 52519) ; collected on August 17-19, 1934, by Dr. P. J. 

 Darlington. 



Records. — The following is the only record known to me: 



Jamaica: Blue Mountains (Darlington, in M.C.Z. and U.S.N.M.). 



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



Remarks. — This species is distinct by the punctures of the pronotum 

 differing in appearance from those of the head, as well as by the coarse 

 punctures of the abdomen, the reduced elytra, and the feeble male 

 characters. 



1 have received no record of its habits.
