or longitudinal folds at base, and from Batophila, which it resembles in 
this respect, by having the thorax margined at base; the posterior 
coxe are rather broadly distant at base, and the punctuation of the 
elytra is obsolete at apex. Weise (l.c. p. 706) mentions five European 
species as belonging to the genus, but one of these, O. (Crepidodera) 
ventralis, can hardly be included under it (v. foot-note, p. 334). 
O. salicarizw, Payk. Oval, convex, rather shining, rufo-testaceous 
with the breast and abdomen black ; the antenne are slightly infuscate 
towards apex, and the 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 Crepidodera ventralis, 
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 Hpitrix) contains about one hundred and ten species, 
whieh are widely distributed in Europe, Northern Asia. Africa, and 
North Central and South America; one species, also, has recently been 
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 coxe 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 dilated, 
so that several of the larger species have the power of leaping less 
developed than is the case with some members of the tribe, and there is 
no apparent spine at the apex of the tibie. 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. Foudras 
and Weise have divided the genus into several separate genera on the 
formation of the frontal tubercles, the shape of the last joint of the 
maxillary palpi, the pubescence, &ec.; of these I have adopted 
Hippuriphila, Ochrosis and Epitric, and have included the others under 
Crepidodera.,
