Dromius YARRiE, sp.nov. 



Oblongo-ovatus; nitidus; piceo-niger, elytris caeruleo-cupreoque- 



subiridescens, antennis palpis mandibulis pedibusque 



sordide testaceis, femoribus coxis et metasterno medio 



fere albidis ; capite prothoraceque alutaceis haud 



manifeste punctulatis ; illo fere sequali antice obscure trans- 



versiru impresso ; prothorace sat transverso, antice posticeque 



subtruncato, canaliculato, lateribus ab angulis anticis (his sat 



rotundatis) retrorsum ad basin leviter arcuatim angustatis, 



angulis posticis obtusis ; elytris obsolete striatis, interstitiis 



planis, interstitio 4° foveis nonnullis magnis fere obsoletis 



notato. [Long. 1|-, lat. f line. 



This species is very like a Metabletus in general appearance, but 



its mentum appears to be toothed, although it is difficult to be 



quite certain without dissection in the case of so minute a species, 



and I have seen only a single example. It is certainly congeneric, 



I think, with Dromiios humeralis, Macl., from which it differs 



(apart from colour) by its elytra less elongate, less parallel, and 



at their widest behind the middle, as well as by the much more 



obtuse hind angles of the prothorax.

I am confident that this is only a var. of ^S'. corticalis, Fab. ; I 

 have taken it frequently in company with typical examples of 

 that insect, and 1 can find no character whatever to distinguish it 

 except the absence of a forward prolongation of the elytral fascia, 

 and even in respect of that character there are intermediate forms. 

 In both forms the prothorax is very similar in shape, being much 

 narrower across the front margin than at the base, with the sides 

 diverging considerably from the front to (or nearly to) the middle 

 and thence converging slightly with a fairly strong sinuation to 

 the base, which is widely and distinctly (but not very strongly) 

 lobed hindward in the middle, the hind angles being very sharp 

 and with a slight outward direction. I am not sure that the
