MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 91 



Specimens examined. — I have examined seven specimens of this 

 species in the British Museum. Four are from Trinidad. One of 

 these was borrowed for further study. 



liemar'ks. — This species is easily distinguished by the strigulose 

 surface. I find no record of its capture since the original description 

 and no indication of its habits.

Genotype. — Staphylmus piceus Fabricius = Oxytelu^ piceus 

 (Fabricius) (indicated by Dumeril, 1806; designated by Latreille, 

 1810). (The designation of ''0. depressum Grav. (= tetracarinatus 

 Block)" by des Gozis in 1886 cannot stand.) Of Anotylus., Oxy- 

 telus nitidulu^'i Gravenhorst (designated here) , of Caccoporus j 

 Staphylinus piceus Linnaeus = Oxytelus piceus (Linnaeus) (mono- 

 basic) ; of Epomotylus., Oxytelus sculptus Gravenhorst (monobasic) ; 

 of Tanycmerus., 0,r.ytelus luteipemns Erichson (monobasic) ; of 

 Emopotylus^ Oxytelus cuernavacanus Bernhauer (monobasic). 



Diagnosis. — Body moderately depressed; without ocelli; antennae 

 11-segmented, more or less thickened apically; labrum transverse, 

 emarginate ; gular sutures united in anterior two-thirds ; fourth seg- 

 ment of maxillary palpi more or less subulate; pronotum longitudi- 

 nally sulcate; anterior coxal cavities confluent, entirely open behind; 

 front coxae conical, prominent; middle coxal cavities separated by 

 union of mesosternal and metasternal processes; elytra not doliiscent; 

 ])()sterior coxae contiguous, "transverse," not much expanded under 

 the femora; abdomen margined; sternum of first segment absent, 

 second complete, not carinate; posterior trochanters small; front 

 tibiae with a single row of spines; tarsi 3-segmented. 



Remarks. — This large genus shows a considerable variation in 

 many characters. Exceptions can be found to many of tliose in 

 the above diagnosis, but the members of the genus are readily dis- 

 tinguishable at a glance by their peculiar facies. 



I have examined over 1,900 mounted specimens of this genus but 

 have not had time to sort the rest of my West Indian series, which 

 amount to over 10,000 additional examples.
