is wanting, but is replaced by a supplementary tooth 

 anterior to the others and directed internally, so that the 

 tibia becomes a broad digging instrument, recalling the 

 same member in the mole-cricket.

The species of Ccclodcs are very much alike in their 

 general form and appearance, and require careful examina- 

 tion to distinguish tliem. C. nigripcnnis is a small species 

 about the size of C. p)cirvulus, Westw., but besides the 

 difference in the colour of the elytra these are rather more 

 finely and uniformly punctured, the rows of punctures 

 being less evidently paired. The clypeus is short, not 

 much narrowed anteriorly, and shining, but not smooth. 

 The anterior tibia is not elongated, the apical tooth is 

 short and lounded, and the minute denticulations are few.

Trox subcrosus, Fab. 



Specimens of this were brought from St. Vincent by Mr. 

 Smith, who has noted it as occurring commonly in fungi. 

 It is strange that it was not found in Grenada, as it is a 

 very common species distributed over the greater part of 

 the New World. 



Acanthocerus rduccns, Bates. 



The recorded range of this species is from Jalapa, in 

 Mexico, to Panama, but it will probably be found to have 

 a much wider distribution. Five specimens were brought 

 by Mr. Smith from St. Vincent agreeing with the type in 

 all essentials. The lines of punctures upon the elytra are
