West-Indian Longicorn Coleoptera. 31 



Maxillary palj)! imioli longer than the labial, their last joint 

 securiform ; the last joint of the labial suboblong. Antennai 

 reaching beyond the niicUlle of the elytra, with the joints 

 from the third slightly dilated towards their apices and each 

 provided with one or two poriferous pits. Prothorax about 

 as long as broad, and furnished on each side with two spines 

 — one just behind the middle, the other between this and the 

 anterior border ; with the margin cut away obliquely in 

 front of the anterior spine and sinuate between the two spines, 

 as well as behind the submedian spine. Scutellum broader 

 tlian long, slightly emarginate in the middle behind. Elytra 

 very sliglitly and gradually narrowed towards the posterior 

 extremity, each provided at the suture and at the extremity of 

 the lateral margin with a small tooth ; the apical margin 

 between these teeth very feebly denticulate. Prosternal pro- 

 cess truncate behind and very closely applied against the 

 anterior border of the mesosternal process ; the latter with a 

 triangular emargination behind which receives the anterior 

 termination of the metastcrnum. 



This genus is j^erhaps most nearly related to Elateropsis, 

 from which it differs by the bispiuose margins of the pro- 

 thorax, the posteriorly truncate and non- emarginate proster- 

 num, and the short and broad scutellum.
