 the angles ratlier narrowly rounded ; the eyes separated from base by 

 about three times their length; labrum with two slender denticles near 

 middle and a pair of small lateral ones; gular sutures narrowly sepa- 

 rated in front and feebly diverging posteriorly; with very fine and 

 dense setigerous punctures but without distinct ground sculpture. 

 Pronotum about one-fourth longer than v,ide, anterior angles fairly 

 broadly rounded ; sides in front scarcely emarginate, nearly straight to 

 rounded basal angles ; without trace of midline except as posterior ele- 

 vation; punctures and sculpture as on head but a little less distinct. 

 Elytra very finely and densely tuberculate or rugulose-sculptured. 

 Mah, fourth and fifth sternites without fold; fourth with a small but 

 abrupt keel at middle of posterior edge; eighth truncate and with a 

 small triangular incision about as deep as wide. Female^ eighth

 of Comparative Zoology ; one paratype, female, in the United States 

 National Museum (No. 52415) ; collected in July 1938 by Dr. P. J. 

 Darlington. 



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



Hispaniola: Dominican llEa'TTBUo, Sanchez (Darlington, in M.C.Z. and U.S.N.M.). 



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



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

 Scopaeus by the carinate fourth sternite of the male. It l)elongs in the 

 subgenus Scopaeus s. str. 



I liave received no record of its habits.
