MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 481 



base; antennal grooves moderately impressed but even and ending in 

 a single puncture; without additional post-antennal grooves or dis- 

 tinct ocular grooves; with sparse coarse umbilicate pinictures except 

 along middle of vertex, and interspersed with fine punctulae; with- 

 out distinct ground sculpture except at base. Pronotum one-third 

 longer than wide, widest from anterior angles to just before middle, 

 thence feebly but emarginately narrowed to broadly rounded base; 

 with wide smooth median area outlined by two series of five or six 

 punctures, with a lateral series of four or five and a few others; with- 

 out distinct ground sculpture. Ehjtra with moderately coarse sparse 

 punctures arranged in series in outer half only. Ahdomen with sparse 

 fine submuricate punctures at the sides, and indistinct transverse 

 strigulae. Length 4I/2 to 5l^ mm. 



Type locality. — Cuba, Sierra Bonilla. 



T^y/^^s.— Holotype, U.S.N.M. No. 62522, collected on January 5, 

 1929, by Alexander Bierig; three paratypes in the Museum of Com- 

 parative Zoology and one in the United States National Museum, 

 collected in 1936 by Dr. P. J. Darlington. 



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



Cuba: Sierra Bonilla (Bierig, in U.S.N.M.), Trinidad Mountains (Darlington, 

 in M.C.Z. and U.S.N.M.), Gran Piedra Range in Oriente (Darlington, in 

 M.C.Z.), Imias in Oriente (Darlington, in M.C.Z. ). 



Specimens exarnined. — I have seen only the five types. 



Rctnarks. — This species is distinguished by the sculpture of the 

 head and the shape of the pronotum. There appear to be some sex- 

 ual differences in the shape of the head and pronotum. 



The type was received from Sr. Bierig under the name X. pimcti- 

 ceps DuVal, but it is very distinct from that species by the presence 

 of punctulae on the head. 



I have received no record of the habits of this species, except that 

 it has been found at elevations up to 4,000 feet. 



7. XANTHOLINUS DARLINGTONI, new species 



Description. — Head black, rest piceous to piceocastaneous, elytra 

 indefinitely paler across base. Head about one-eighth longer than 

 wide, nearly parallel, basal angles broadly rounded except for a 

 slight angular interruption ; eyes not at all prominent, at nearly two 

 and one-half times their length from base; antennal grooves moder- 

 ately impressed and united at apex by a curved depression, not dis- 

 tinctly punctate; without additional postantennal or ocular grooves; 

 with sparse elongate umbilicate punctures except along middle, and 

 interspersed with large punctulae; with very irregular but distinct 

 ground sculpture of strigulae. Pronotum about one-third longer 

 than wide, widest near anterior angles, thence moderately narrowed
