i. SUNIUS DARLINGTONI, new species 



Description. — Piceous, elytra luf ocastaneous or rufous. Head trans- 

 verse, not emarginate behind, with angles moderately rounded ; eyes 

 veiy small, at over three times their length from base; labrum with a 

 small median emargination bordered by a pair of small blunt 

 tubercles, and with a still smaller pair more laterally ; gular sutures 

 very closely approximated near base; with dense and fine but dis- 

 tinctly umbilicate punctures generally separated by less than half 

 their diameter; without distinct ground sculpture except in depres- 

 sion between eyes and also behind eyes laterally. Pronotmn nearly as 

 wide as head, about one-fourth wider than long, the sides rather 

 strongly converging and rounded into base ; disk with a trace of im- 

 pression on either side of midline near base ; punctation very similar 

 to that of head but obsolescent; without a distinct smooth midline; 

 without distinct ground sculpture. Elytra with rather indistinct 

 submuricate punctures separated by a little more than their diam- 

 eters; without definite ground sculpture. Ahdomen sparsely minutely 

 submuricately punctate, with indistinct ground sculpture. Male^ 

 eighth sternite with a very small semicircular emargination. Female^ 

 sternites not modified. Length, 4 to 4^/^ mm. 



Type locality. — Dominican Republic, Loma Vieja, south of Con- 

 stanza, elevation about 6,000 feet. 



Types. — Holotype, male, and one paratype, female, in the Museum 

 of Comparative Zoology, collected in August 1938 by Dr. P. J. Darling- 

 ton; two paratypes in the United States National Museum (No. 

 52510) . (All three paratypes collected at Loma Rucilla and the moun- 

 tains to the north in June 1938.) 



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



Hispaniola: Dominican Rei>ubuc, Loma Vieja (Darlington, in M.C.Z.), Loina 

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



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



Remarks. — This species is distinguished by the obsolescent pronotal 

 punctures, the small eyes, and the denticles of the labrum, in addition 

 to the characters in the ke3^ It is an unusually shiny species and 

 probably belongs in the subgenus Sunius s. str. 



I have received no record of its habits.
