MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 363 



seen no examples and am unable to state ^yhethe^ it belongs here 

 or not. 



Sharp's original description of the tarsus is as follows: "The 

 terminal joint is, however, inserted above the fourth joint very near 

 the base of the third; as the fourth joint is placed underneath the 

 terminal one, and is not wider than it, the foot appears to be 

 4-jointed." I have not been able to verify this on my single speci- 

 men. The tarsi there are very distinctly slender, the segments de- 

 creasing in size from the first to the fourth, and with the apex of 

 each only a little diagonally truncate. 



I have seen only three specimens of a species that appears to be 

 distinct from the previously known species. 



1. SUNIOCHARIS VOLANS, new species 



Description. — Kufopiceous, pronotum rufous, elytra indefinitely 

 testaceous at apex. Head, subquadrate, truncate behind, the angles 

 right; eyes small, at much more than their length from base; an- 

 tennae short and stout, segments 7 to 10 transverse, 11 longer than 

 y and 10 together; punctate but with fine and rather dense tuber- 

 culi somewhat obscured by indefinite ground sculpture ; clypeus trun- 

 cate in front. P/onotmn as wide as head, one-eighth wider than 

 long, obtrapezoidal, widest at front, feebly narrowed behind, angles 

 moderately narrowly rounded; with feebly depressed midline basally ; 

 with tuberculi as on head or a little coarser; with short pubescence. 

 Elytra about as wide as long, otie-sixth longer than pronotum; sur- 

 face densely covered with tiny elongate tuberculi, arranged longitu- 

 dinally more or less in series, shining surface visible between ; with 

 rather long pubescence. Ahdamen rather densely, finely, and trans- 

 versely serially submuricately punctate, less distinct and dense 

 apically. Male., unknown. Female..^ apical tergites and sternites 

 unmodified. Length, 3 mm. 



Type locality. — Trinidad, between Sangre Grande and Sans Souci 

 by way of Toco, parishes of St. Andrew and St. David. 



Types. — Holotype, female, U.S.N.M. No, 52395, collected by me on 

 December 15, 1935; two paratypes, female, in Museum of Compara- 

 tive Zoology and United States National Museum, collected in 1935 

 by N. A. Weber. 



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



Trinidad: Sangre Grande (Blaokwelder station lOOB), Maracao Valley (Weber, 

 in U.S.N.M.), San Rafael (We]K<r, in M.C.Z.). 



Specimens examined. — I have seen only the three types. 



Remarks. — This si)ecies differs from the Central American species 

 described by Sliar]) in its much smaller size, stouter antennae, and 

 probably other characters not mentioned in the descriptions. 



The type was caught flying at du.sk.
