MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 87 



Remarks. — It appears to me unlikely that this species is a variety of 

 T. corticinm (Gravenhorst), but I am unable to add to the information 

 outlined above. 



I find no record of its habits. 



VI. Genus TORRENTOMUS Bierig 



ToiTcniomus Biebig, I934e, p. 213. 



Genotype. — T. torrel Bierig (original designation and monobasic). 



Diagnosis. — Parallel and feebly convex; body with rather dense 

 sculpture; without ocelli: labrum transverse, arcuate; head very 

 strongly constricted behind; pronotum not transversely sulcate; inner 

 apical angles of elytra not broadly rounded ; tibiae pubescent. 



Retnarks. — The above characters were taken from Sr. Bierig's de- 

 scription. In addition to these the new species here described 

 shows the following features : Antennae 11-segmented, filiform ; gular 

 sutures united in anterior half; fourth segment of maxillary palpus 

 subulate; anterior coxal cavities confluent and open behind; front 

 coxae conical, prominent; posterior coxae contiguous, transverse; 

 sternite of first abdominal segment absent, of second complete; tarsi 

 3-segmented. 



This genus is very similar to both Oxytelus and Garpelimus., 

 although it is more likely to be confused with the former. I have 

 seen examples only of the new species tenebrosus.

Descrijytioii. — Ferrugineous, pronotum testaceous, elytra brownish
