above with a few large punctures even on vertex and with fine punc- 

 tures scattered among the dense longitudinal strigulae. Pronotum 

 about one-half longer than wide, widest in anterior third, feebly 

 narrowed to basal third; with two pairs of discal punctures forming 

 a square, and with two or three lateral punctures ; with fine strigulae 

 not always longitudinal. Elytra with a very few large setigerous 

 punctures and with traces of smaller punctures over the very uneven 

 surface; without ground sculpture. Abdomen with a few setigerous 

 punctures; with sparse transverse strigulae. Length, 5 to 6 mm. 



Type locality. — Cuba. 



Types. — Presumably in the collection of Blanche Rancin, Caen, 

 France. 



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



Cuba: (Fauvel, 1863; Bernhauer and Schubert, 1914), Cayamas (Schwarz, in 

 U.S.N.M.), Loma del Gato, Cobre Range, Oriente (Darlington, in M.C.Z.), 

 Buenos Aires, Trinidad Mountains (Darlington, in M.C.Z.), Punta Brava 

 (Bierig, in U.S.N.M.). 



Hispaniola: Haiti, Diquiui (Mann, in M.C.Z.) ; Dominican Repubijc, Mount 

 Diego de Ocampo (Darlington, in M.C.Z. and U.S.N.M.). 



Specimens examined. — ^I have seen eight examples in the United 

 States National Museum and six from the Museum of Comparative 

 Zoology. 



Remark':. — These specimens seem to be properly identified with 

 Fauvel's species. It is distinguished by the margining of the under- 

 side of the head, the absence of the submarginal groove, and the 

 sculpture of the under surface. 



Sr. Bierig has transferred this species to the genus Metoponcus. 

 This must liave been done without reference to Casey's remarks (1906, 

 p. 360) on this genus and without examination of the genotype 

 (hrevicornis Erichson), since either of these would have called atten- 

 tion to the unusual structure of the epistoma between the bases of 

 the antennae. This is quite sufficient to separate the New World 

 species, some of which were placed by Casey in OligoUnus and one 

 of which has since been placed in Stenolinus by Bierig. Mctoponaiis 

 in the Old World sense has not yet been found in the New World. 



Bierig records this species (as larvae) from "unter loser, feuchter 

 und mulmiger Einde gefallter Baume." 



5. OLIGOLINUS VARIABILIS, new species 



Description. — Head and iDronotum rufous, elytra black (or pice- 

 ous) with base irregularly testaceous, abdomen piceous with basal 

 two and apical two segments testaceous or castaneous. Head nearly 

 one-fourth longer than wide, slightly enlarged behind with basal 

 angles broadly rounded; antennal grooves almost completely obso- 

 lete; ocular grooves distinct though obsolescent near the eyes; with 

 a distinct marginal ridge at sides beneath ; with a very few scattered
