MOXOGRAPH OF WEST INDIAN STAPHYLINIDAE 459 



I have seen four specimens from tlie West Indies representing 

 two species of which one is new. 



KEY TO WEST INDIAN SPECIES OF CEPHALOXYNUM 



1. Head with two deep foveae on vertex 2. rambouseki 



Head without foveae on vertex 1. chapini 



1. CEPHALOXYNUM CHAPINI, new species 



Description. — Head rufopiceous, pronotum and abdomen nifotes- 

 taceous, elytra fuscotestaceous. Head quadrate, one-tenth longer than 

 wide ; with coarse and distinctly umbilicate punctures scattered evenly 

 except along middle, generally separated by more than their diameter ; 

 surface with fine but distinct scaly ground sculpture throughout. 

 Pronotum. one-ninth longer than wide, front angles broadly rounded, 

 sides straight posteriorly and moderately narrowed, hind angles dis- 

 tinct; more finely punctate than head, but evenly except for smooth 

 median space; with scaly ground sculpture finer than on head. 

 Elytra moderately densely but feebly punctured ; surface shining but 

 slightly uneven. Abdomen sparsely and finely submuricately punc- 

 tured ; with indistinct transverse strigulae. Length, 2^2 mni. 



Type locality. — Jamaica, between Fern Gully and Ewarton in vicin- 

 ity of Moneague. 



Types. — Holotype, in the United States National Museum (No. 

 52456) collected by Chapin and Blackwelder on February 2, 1937. 



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



Jamaica: Moneague (Blackwelder station 375). 



Specimens examined. — I have seen only the unique type. 



Remarks. — This species is very distinct by its even head without 

 ridges or depressions. The shape of the pronotum is also distinctive, 

 as well as the even arrangement of the pronotal punctures. 



The type was taken flying at dusk.

 BiERiG, 1937, p. 273. 



Description. — Testaceous, head picescent especially about the eyes, 

 elytra piceous except indefinitely at base, fourth and fifth visible ab- 

 dominal segments piceous. Head quadrate, as broad as long; with a 

 deep circular fovea on each side of midline at center of vertex, smooth 

 midline feebly but broadly elevated toward front ; with coarse punc- 

 tures separated by about half their diameters ; with very vague stri- 

 gulose ground sculpture. Pronotuon as broad as long, front angles 

 not rounded, sides gradually curved into rounded base ; without dis- 

 tinct punctures; ground sculpture as on head. Elytra with punctures
