of St. Vincent, Grenada, and the Grenadines. 19 



of exceedingly minute punctures. Anterior tibife widening out- 

 wards, sharply denticulate on their outer edge. Length 3-3^, 

 breadth |-| mm. 



Hah. St. Vincent — Leeward side. 



Two specimens. This and the following species have 

 quite the facies of a Corticeus (HyjwjMoeus), from which 

 genus they may be known by the form of the anterior 

 tibise and by the elytra completely covering the abdomen. 

 In the typical species from Central America the man- 

 dibles are furnished with long ei^ect horns in the male, as 

 in Gnaihocerus, Echocerus, etc. The insects here described 

 are without these appendages, and they are probably all 

 females. 



Icclns grenadensis, n. sp. 



Closely allied to I. rufotestuceus, and differing as follows : — The 

 head shorter, the sides of the front narrower ; the epistoma limited 

 behind by a deep transverse groove, terminating laterally in a 

 rather deep fovea ; the antenna) with joints G-10 very strongly 

 transverse, 5 transverse but much narrower than G. Prothorax 

 shorter, much broader than long, and more finely punctured. 

 Anterior tibite narrower, obsoletely denticulate on their outer 

 edge. Length 2|, breadth | mm. 



Hah. Grenada — Balthazar, on the Windwai'd side. 



One specimen, captured on the wing at sunset.

Hah. St. Vincent ; Grenada. 



The cosmopolitan insect generally known as T. ferrit- 

 gineum, Fabr., has been recorded by MM. Fleutiaux and 

 Salle from Guadeloupe; it is probable, however, that the 

 Fabrician name has been wrongly applied.
