MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 485 



even on the disk; without trace of ground sculpture on the polished 

 surface. Pronotmii nearly one-half longer than wide, widest at 

 anterior angles; sides nearly straight and slightly converging to 

 the broadly rounded base and hind angles ; median smooth space out- 

 lined by two series of nine or ten punctures, with an indefinite 

 lateral series and a few others scattered at sides; without trace of 

 ground sculpture. Elytra with moderately coarse punctures not 

 serial except at sides; surface indistinctly coriaceous. Abdomen 

 sparsely and finely submuricately punctate throughout; with feeble 

 ti'ansverse strigulose ground sculpture. Length, 8 mm. 



Type locality. — Haiti, Etang Lachaux on the southwest peninsula. 



Types. — Holotype in the Museum of Comparative Zoology, col- 

 lected on October 26-27, 1934, by Dr. P. J. Darlington. 



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



Hispaniola: Haiti, £tang Lachaux (Darlington, in M.C.Z.). 



Specimens examined. — I have seen only the holotype. 



Remarks. — This species is distinct in the punctures of the head, 

 which though fairly large at the surface are smaller at the bottom 

 where the circle is all that makes them umbilicate. The elongate head 

 and feeble antennal grooves are also unusual. 



I have received no record of the habits of this species. 



12. XANTHOLINUS BEATTYI, new species 



Description. — Head black, pronotum, elytra, and abdomen slightly 

 rufescent, elytra with tips of humeral angles indefinitely testaceous. 

 Head about one-twelfth longer than wide, rather distinctly cordate 

 with the mandibles, though the basal angles are not very broadly 

 rounded ; antennal grooves distinct though not very coarse, not punc- 

 tate except near tip; with an additional fine oblique groove from the 

 base of the antennae; ocular grooves absent; with scattered large 

 umbilicate punctures except along middle, with very sparse minute 

 punctulae between but without ground sculpture. Pronotum one- 

 fourth longer than wide, widest at anterior angles, sides nearly 

 straight and moderately narrowed at base w'hich is broadly rounded ; 

 median smooth space outlined by two irregular series of six or 

 seven punctures, with an indefinite lateral series and a few addi- 

 tional punctures; without ground sculpture. Elytra with coarse 

 punctures not serial except at sides of disk; surface indistinctly 

 coriaceous. Abdomen sparsely but not very finely submuricately 

 punctate; with indefinite transverse strigulae. Length, 6 to 8 mm. 



Type locality. — St. Q-oix, Butler Bay Estate. 



Types.— hloloiy^Q and two paratypes, U.S.N.M. No. 52432, col- 

 lected by me on November 14, 1936.
