Diagnosis. — Head cylindrical, eyes generally prominent, without 

 ocelli; antennae 11-segmented; labrum large, transverse; maxillary 

 palpus subulate; gular sutures united; pronotum not sulcate; hypo- 

 mera with a lobe partly behind the coxae; anterior coxal cavi- 

 ties open behind and confluent ; front coxae large, exserted ; scutellum 

 generally not visible; middle coxal cavities narrowly separated; 

 posterior coxae contiguous, "transverse"; abdomen margined, first 

 sternite absent; tibiae not spinose; tarsi 3-segmented. 



Remarks. — This is a very difficult genus. It has not been properly 

 studied in any part of the New World, at least. Careful comparison 

 with types and paratypes has made me reasonably sure of the identi- 

 fication of all but four of the species recorded from the West Indies. 

 A key is presented that includes only the species known to me by 

 specimens. It is considered only as a preliminary attempt and will 

 not be found adequate for all material. Indeed, I have numerous
