with tiny elevated setigerous tuberculi, rather dense and even; pub- 

 escence moderately long. Anterior tarsus feebly dilated. Ahdotnen 

 finely asperately punctate. Male, seventh sternite not modified; 

 eighth with a small rounded emargination. Female, sternites not 

 modified. Length, 31/4 to 3i/^ mm. 



Type locality. — Cuba, Cayamas, 15 miles west-northwest of Cien- 

 fuegos, province of Santa Clara. 



Types. — Holotype, male, and five paratypes, U.S.N.M. No. 52409, 

 collected by E. A. Schwarz on January 13 (also January 6, March 

 2, and December 19) of 1902, 1903, or 1904. One paratype has been 

 deposited in the collection of Dr. Cameron and one in my own 

 collection. 



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



Cuba: Cayamas (Schwarz, in U.S.N.M.), Soledad (Darlington, in M.C.Z.). 



SpeciTnens examined. — I have seen only the eight types in the 

 United States National Museum and one other example in the Museum 

 of Comparative Zoology. 



Remarks. — The position of this species is not altogether certain. 

 The dense ground sculpture obscures the punctures to a large extent, 

 but it is possible that it belongs closer to Medon. It is chiefly dis- 

 tinguished by the form of the gular sutures. It belongs in the sub- 

 genus Ophiomedon. 



I have no record of its habits.

 without ground sculpture ; eyes at more than their length fi'om base ; 

 antennae posteriorly flexile, not strongly geniculate, basal segment not 

 much elongate, first two not much larger than rest; labrum with 

 median tooth but without paired denticles ; fourth segment of maxil- 

 lary palpus very small, subulate; gular sutures not at all united, 

 rather widely separated in front but very approximate posteriorly;
