or longitudinal folds at base, and from liatophila, which it resembles in 

 this respivt, by having the thorax margined at base ; tho posterior 

 coxae are rather broadly distant at base, and the punctuation of the 

 elytra is obsolete at apex. Weise (I.e. p. 706) mentions five Euroj)ean 

 species as belonging to the genus, but one of these, O. (Crejwfalera) 

 ri-ntralis, can hardly be included under it (v. foot-note, p. 334). 



O. salicarice, Park. Oval, convex, rather shining, rufo-testaceoua 

 with the breast and abdomen black ; the antenna; are slightly infuscate 

 towards apex, and tho suture of the elytra is very narrowly ferruginous ; 

 head thickly punctured, thorax scarcely twice as broad as long, very 

 finely punctured, without a trace of a transverse impression or longitudinal 

 fold at base, a point that will separate it from Crepidcxlera ventruli*, 

 which it closely resembles ; elytra broader at base than thorax, with the 

 shoulders well marked, punctured in moderate rows, which become 

 obsolete towards apex. L. 2-2^ mm.

CREPIDODERA, Chevrolat, 



This genus in its wider sense (excluding, however, the now universally 

 received genus EpHrif) contains about one hundred and ten species, 

 which are widely distributed in Europe, Northern Asia. Africa, mid 

 North Central and South America ; one species, also, has recently 1* en 

 described from Australia, so that ultimately the genus will probably 

 prove to be a very extensive one ; of the thirty European species, nine 

 are found in Britain ; they are oval or oblong-oval insects, very variable 

 in colour, and may be known by the transverse impression at the base of 

 the thorax, which is bounded on either side by a raised fold, taken in 

 conjunction with the closed anterior coxal cavities, and the fact that 

 the coxae are only slightly distant ; the elytra are punctured in rows, 

 which, as a rule, are strongly marked ; the frontal keel is usually sharply 

 raised; the posterior femora are rather long and only moderately diluted, 

 so that seveial of the larger species have the power of leaping 1- -> 

 developed than is the case with some members of the tribe, and there is 

 no apparent spine at the apex of the tibiae. In the male the first joint 

 of the anterior tarsi is, usually, more or less dilated, and the fifth ventral 

 segment of the abdomen is truncate or subtruncate at apex. Koudras 

 and Weise have divided the genus into sevenl separate genera on the 

 formation of the frontal tubercles, the shape of the last joint of the 

 maxillary palpi, the pubescence, Ac. ; of these I have adopted 

 ////'/</// //<// ///f, Ochroais and fyiifiis, and have included the others under 

 1'i'lera.
