West-Indian Covylophiila^ and TrichoptcrygicUu. 339 



from anv other by its liemisplicric form, large and very 

 sliining thorax, and short attenuated elytra. 



It was found very plentifully in the islands of Grenada 

 and St. Vincent. 



Trichopteryx occidentah's^ sp. n. 



L. c. O'SO mm. Ovata, convexa, lata, postice attenuata, pilis flaves- 

 ccntibus vcstita ; pronoto nigro, confcrtim tuberculato, angulis 

 postorioribus vakle prodiictis, dilutioribus : elytris fuscis, attenu- 

 atis ; antonnis longis atque pedibiis flavis. 



If we may judge from the multitude of specimens (upwards 

 of five hundred) collected by Mr. Smith, this species must 

 abound in the utmost profusion in the West-Indian Islands. 

 Although it varies much in size, which is probably a sexual 

 difference, I cannot discover any valid specilic distinctions 

 throughout the whole of this immense series. 



2\ichopteryx depressa, sp. n. 



L. c. 0-00 mm. Oblongo-ovalis, sat depressa, baud attenuata, 

 piceo-nigra ; pronoto magno, vix dilatato, tuberculis distinctia 

 irregularitor dispositis, interstitiisque reticulatis ornato ; elytris 

 parallelis ; antennis atque pedibus flavis. 



T. depressa differs from the preceding species in its more 

 depressed and parallel form and in its uniform black colour. 

 It seems to be less common than either of the foregoing, but 

 was found in the same localities. 



Trichopteryx Crotchu, Matth. 



Trichopteryx Crotchii, Matth. Ent. Month. Mag. vi. p. 248 (1865). 



This species was first described by me from specimens 

 taken by Mr. G. E. Crotch in the Canary Islands. Since 

 then it has been found in many parts of America and now 

 not uncommonly by Mr. Smitii in the West-Indian Islands. 



Trichopteryx grenadensis, sp. n. 



L. c. 0-60 mm. Oblonga, brevis, lata, atra, modice tuberculata, sat 

 depressa; pronoto atque elytris utrisque prope media dilatatis ; 

 elytris brevibus ; antennis brevibus atque pedibus flavis. 



Only two specimens of this well-marked species were found 

 by Mr. Smith in Grenada. It belongs to a small group of the 

 genus represented in Europe by T. Edithia and in Central
