MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 487 



Specimens examined. — I have seen only the holotype. 



Remarks. — This specimen is possibly somewhat immature, but this 

 apparently affects only the depth of color. It is distinguished from 

 heattyi by the length of the temples and by the sparse punctures on 

 the disk of the head. 



The type was taken by sifting trash beneath a mud bank. 



14. XANTHOLINUS JAMAICENSIS, new species 



Descriptioii. — Piceous, pronotum somewhat rufescent. Head about 

 one-fourth longer than wide, slightly narrowed in front, sides feebly 

 arcuate behind and broadly rounded into base ; eyes not prominent, at 

 a little less than three times their length from base ; antennal grooves 

 feebly impressed, ending in a puncture; with an additional fine oblique 

 groove from base of antennae; distinct ocular grooves absent; with 

 moderate umbilicate punctures separated by half to two times their 

 diameter; with fine strigulose gi-ound sculpture. Pronotum one-half 

 longer than wdde, widest at anterior angles, sides straight and feebly 

 converging to rounded basal angles; dorsal series irregular but with 

 11 or 12 punctures, and with scattered lateral punctures; with feeble 

 though distinct strigulose groimd sculpture. Elytra with irregular 

 punctures not coarse or dense and not at all serially arranged; sur- 

 face very uneven but without groimd sculpture. Ahdomen with sparse 

 fine submuricate punctures and feeble transverse strigulose ground 

 sculpture. Length, T nun.

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



Jamaica: Kingston (Darlington, in M.C.Z.). 



Specimens examined.. — I have seen only the holotype. 



Remarks. — This species is distinguished by the additional post- 

 antennal grooves and tlie sculpture of the head and pronotum. The 

 pronotum is unusually slender. 



I have received no record of its habits. 



15. XANTHOLINUS IMPUNCTUS, new species 



Description. — Piceocastaneous, pronotum rufocastaneous. Head 

 about one-fourth longer than wide, slightly narrowed in front, sides 

 feebly arcuate behind and broadly rounded into base; eyes not promi- 

 nent, at less than three tiines their length from base; antennal grooves 

 moderately impressed, straight, ending in a puncture; wdth an addi- 

 tional fine oblique groove from base of antenna ; a slight depression for 

 ocular groove ; with umbilicate punctui-es (except along center) vary- 

 ing in size, separated by one to two times their diameter; with fine
