MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 145 



antennae; moderately coarsely but irregularly punctate, obsoletely 

 in front; with a vague trace of ground sculpture. Pronotum two- 

 fifths wider than long, widest at anterior third, strongly narrowed to 

 base but with a subtuberculate prominence^ at middle and an 

 emargination behind it; base one-half as wide as maximum; posterior 

 emarginations forming short vertical grooves on the sides, somewhat 

 visible from above; punctures coarse but scattered, frequently 

 coalescing, and with a few larger punctures symmetrically placed in 

 pairs; disk rather flattened, sometimes feebly depressed about an 

 irregular smooth center elevation ; with only a trace of vague ground 

 sculpture. Elytra scarcely one-fifth wider than pronotum, rather 

 strongly rounded at sides; hind angles rounded; punctures very 

 coarse, generally separated by less than their diameter; with only a 

 trace of vague ground sculpture. Abdomen with very large but very 

 shallow punctures, especially on basal segments; ground sculpture 

 more definite than on other parts. Length, 21/2 to 3 mm. 

 Type locality. — "Antilles: Guadeloupe; Saint-Vincent." 

 Types. — ^Presumably in the collection of Blanche Rancin, Caen, 

 France. 

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



Montserrat: (Hubbard, in U.S.N.M.). 



Guadeloupe: (Fauvel, 1902; Leng and Mntchler, 1914). 



St. Lucia: (Blackwelder station 211D, 220D). 



St. Vincent: (Fauvel, 1902; Leng and Mutchler, 1914; British Museum). 



Specimens examined. — One example in the British Museum, three 

 in the United States National Museum, and five collected by me in 

 1935-37. 



Remarks. — This species varies slightly in the flatness or depression 

 of the disk of the pronotum and the number of the larger punctures. 



It has been collected from rotting banana stalks and from decaying 

 cocoa pods.

Espeson euplectoides Fauvel, 1902a, p. 37.— Beenhaueb, 1910, p. 352. — Bernhaueb 

 and ScHUBEHT, 1910, p. 24. — IjEng and Mutchler, 1914, p. 403. 



Description. — Rufous throughout. Head convex, one-fifth nar- 

 rower than pronotum, strongly rounded behind the eyes, scarcely 

 constricted at neck above; dorsal tentorial pits visible on vertex 

 posteriorly; with distinct supraantennal prominences; moderately 

 coarsely but irregularly punctate, less definitely in front; with only 

 a vague trace of ground sculpture. Pronotum one-fifth wider than 

 long, widest at anterior third; anterior angles rounded; sides without 

 prominence at middle, narrowly emarginate near base ; base less than 



■f This prominence is tuberculiform only in profile. It is formed by a carina which runs 

 diagonally from the dorsal to the ventral side, enclosing a concavity on its anterior side.
