MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 375 



Genotype. — S. pallidwn Sharp (designated by Casey, 1905), 



D'l-agnosi^, — Body very narrow and elongate; sides of head 

 strongly grooved behind the eyes; vertex not carinate; eyes small, 

 not prominent; antennae posteriorly flexile, rather strongly 

 geniciihite, basal segement not much elongate, first and second not 

 enlarged with rest slender; labrmn broadly feebly emarginate, not 

 denticulate; third segment of maxillary palpus subspherical, fourth 

 minute, retractile; gnlai- sutures united throughout; neck very slen- 

 der; prothorax elongate but not greatly prolonged in front; pro- 

 sternum dilated under the front coxae and connate with the liypomera ; 

 hypomera not lobed behind the coxae; anterior coxal cavities open 

 behind but closed beneath by the prosternal expansions; anterior 

 coxae large, exserted; middle coxal cavities confluent; posterior 

 coxae contiguous, ''conical"; first and second abdominal sternites 

 absent; tarsi filiform, five-segmented, fourth segment not lobed 

 beneath. 



RemarJxS. — This is the first record of this genus north of the 

 Amazon Valley in Brazil. There can scarcely be any question of 

 the identification because of the very distinct features of this genus. 

 I have examples of the genotype for comparison. 



One specimen from Cuba is all that I have seen from the West 

 Indies. It seems to ])e a new species, although I am not able to 

 compare it with all the Amazon species. 



1. SPHAERONUM BERBERUM, new species 



DescHption. — Rufocastaneous. Head with sides evenly rounded into 

 base, eyes at about four times their length from base ; with a distinct 

 groove from below eye to neck on each side; with rather small but 

 distinctly umbilicate punctures except along front margin, with dis- 

 tinct but not strong scaly ground sculpture; neck one-ninth as wide 

 as head. Pronotum about twice as long as broad; widest at anterior 

 two-fifths, moderately but evenly narrowed beliind, more abruptly 

 and nearly emarginately in front; with punctures about half as large 

 as on liead, less regular and more obscured by the irregular ground 

 sculpture; narrow midline impunctate, somewhat elevated behind. 

 Elytra a little shorter than pronotum, one-fifth longer than broad ;^ 

 with shallow and somewhat indistinct punctures usually separated by 

 their diameter or more; without distinct ground sculpture. Ahdomen 

 without distinct punctures but surface very uneven, not distinctly 

 sculptured. Mole, unknown. Fanale^ sternites not modified. Length,
