464 BULLETIN 182, UNITED STATES NATIONAL MUSEUM 



Specimens examined. — I have seen only the type and one example 

 from the Museum of Comparative Zoology. 



Remarks. — This species is distinguished by its quadrate head, its 

 coarse and sparse pronotal punctures, and its uniform black color. 

 I am unable to distinguish the Cuban example from the type. It was 

 taken at an elevation of 3,000 to 4,000 feet. 



A species very similar to this occurs in Central and South 

 America. It may differ in details of sculpture or may be the same 

 species. I am unable to determine the range of variation of the 

 West Indian species so cannot state definitely whether they are the 

 same or not. 



The type was found under bark of a silk cotton tree. 



LXXIV. Genus HETEROTHOPS Stephens 



neterothops Stephens, 1829, p. 284. 

 Trichopygus Nobdmann, 1836, p. 137. 

 Heterotopa Nokdmann, 1836, p. 137 (misspelling). 



Genotypes. — Staphylinus hinotatus Gr?iyenhorst=neterothops bi- 

 notatus (Gravcnhorst) (designated here). Of Trichopygus^ T achy- 

 poms dissimilis Gra\enhoTst= Trichopygus dissimilis (Gravenhorst) 

 (designated by Tottenham, 1939). 



Diagnosis. — Head and pronotum without dense umbilicate punc- 

 tures, more or less margined beneath the eyes ; antennae widely sepa- 

 rated at front of head, not geniculate nor serrate, outer segments 

 densely pubescent from third or fourth segment; labrum transverse; 

 mouthparts short; palpi subulate, fourth segment of maxillary 

 shorter than third, third segment of labial slender; gular sutures 

 separate ; lateral margin of pronotum simple ; anterior coxal cavities 

 entirely open behind; front coxae large, exserted; posterior coxae 

 contiguous, with a small expansion over the base of femur; first 

 and second abdominal sternites absent; femora unarmed; tarsi all 

 6-segmented. 



Remarks. — This is a moderate-sized genus occurring throughout 

 the world but generally with rather limited specific ranges. It is 

 distinguished principally by the structure of the mouthparts, but 

 in the West Indies may be known among Quediinae by its 5-seg- 

 mented tarsi or the short palpi. 



Two new species are all that are known to me from the West 

 Indies.
