previously been recorded from Mexico, but will no doubt 

 be found in other West Indian islands. 



Fscudocanthon chlorizcms, Bates, 



A specimen was found in Mustique, and another in 

 Union Island, in the Grenadines. This species also has 

 only so far been known from Mexico. The green tinge is 

 exceedingly faint, as in the specimens from Yucatan, and 

 traceable only on the head and thorax. The elytra are 

 quite black in all known examples except the type, found 

 in Juquila. 



The angulate inner edge of the front tibia of the male is 

 the only substantial distinction between this genus and 

 Canthon, the parallel-sided thorax mentioned by its author 

 being only an optical effect produced in a particular position 

 of the specimen. 



UrCi/s VinccnticV, sp. n. 



Parum elongatus, cupreo-niger, nitidus, capite polito, sat crebre 

 punctato, oculis supra angustis, clypei margine setoso, medio biden- 

 tato ; protliorace Isevissime punctato, lateribus valde angulatis, pro- 

 funde sulcatis, sulco ad basin attingente ; elytris extus carina Integra 

 apice paulo depressa circumdatis, striatis, striis baud perspicue 

 punctatis ; pygidio polito convexo, basi profunde bi-iinpresso ; tiljiis 

 anticis gracilibus, tridentatis, dentibus omnibus multo post medium 

 positis. 



Long. 3-4 mm. 



Hah. St. Vincent, Cumberland. 



Two specimens of this minute species were found beneath 

 rubbish on a damp rock near the sea. It has the form and 

 size of U. 2^ygm^us, Harold, but the upper division of the 

 eyes is narrow, and there are no supplementary teeth on 

 the margin of the clypeus. The disk of the latter is with- 

 out any trace of transverse wrinkles. The slight depression 

 at the suture of the carina surrounding the elytra suggests 

 the origin of the apical processes which form such a 

 remarkable feature of some of the larger species of this 

 genus.
