British Mueuin as humeralis; and certainly it agrees well with 

 the description of that species. It is true the rostrum was 

 described as bicarinate, but the narrow median carina is not 

 always present, and even when it is, is sometimes concealed 

 by scales. 



A specimen sent to me as humeralis by the late Rev. T. 

 Blackburn is really not that species, bnt a new one, here 

 d.esribed as recurvus. At the time I tabulated the genus * 22) 

 I had seen but the one specimen and noted (23) its discrepancies 

 from the original description, but was under the impression 

 that he had connecting forms, which, however, was not the 

 case.< 24) The table in consequence was inaccurate as regards 

 humeralis and hypocritus. In the table, therefore, for 

 humeralis substitute recurvus, and for hypocritus substitute 

 /•// izophac/us var . (25) 



Leptops rhizophagus, n. sp. 



<S . Black. Clothed with scales varying from grey or 

 ochreous-grey to golden ; the elevated parts with small, black, 

 indistinct scales. 



Head with small, dense punctures. Rostrum rather long; 

 sublateral sulci deep and closed at both ends, narrowly 

 impressed along middle, with an even ridge between same 

 and each sublateral sulcus. Prothorax about as loii£ as wide, 

 widely and shallowly depressed along middle, transversely 

 impressed before and behind middle, the sides vermiculate. 

 Scutellum distinct. Elytra at extreme base scarcely wider 

 than prothorax, but much wider beyond middle; with rows 

 •of large, partially concealed punctures; suture thickened but 

 not tuberculate ; third, fifth, and seventh interstices obtusely 

 tuberculate. Tih'uc denticulate on lower-surface. Length 

 •(excluding rostrum), 11-13 mm. 



9 . Differs in being larger (14-16 mm.) and wider, pro- 

 thorax somewhat transverse, elytra much larger, and legs 

 somewhat shorter.

(24) There were three other specimens of the species standing 

 in his collection as humeralis. 



(25) The specimen I tabulated as hypocritus has a feeble median 

 carina, and another specimen of the species lias a still more feeble 

 one, but on all the other specimens examined the rostrum is deeply 

 but narrowly impressed along the middle. •
