in almost a straight line, parallel with the sides of the thorax, until 
they terminate in a minute and acute point ; the whole projection 
occupying about a third of the lateral length, and suggesting the idea 
of the dens posterior being amalgamated with the prominence of the 
anterior angle. Below the acute point above mentioned, the sides 
(which are strongly and straightly narrowed behind) are exceedingly 
finely crenulated ; the margins, as compared with those of C. vini, being 
indeed almost entire. In other respects this insect is conspicuous by 
the "almost cylindrical shape of its elytra, which are closely and deli- 
cately punctured, and thickly clothed with short pubescence. 
Another species of this genus, G.fuscicornis (Sturm, Deutschl. Ins., 
xvi, 97, 18 ; Er., Ins. Deutschl., iii., 358, 10), must, I think, be added to 
our lists, as I have found a specimen, agreeing in the majority of its cha- 
racters with Erichson's diagnosis, among some Cryptophagi belonging to 
Mr. D. Sharp, and taken by him in the London district. It is f lin. 
long, rather smaller than auyC. dentatus,iYovav!]i\c\i the much stronger 
and wider punctuation of its elytra, its somewhat more cylindrical 
shape and the structure of its thorax distinguish it ; the anterior angles 
being strongly prominent, and terminating behind in a sharp tooth, and 
the lateral tooth being situated at the middle of the sides, which are 
more narrowed behind it, and less strongly crenulated. 
I am, however, compelled to bring this species forward with a 
certain amount of doubt, not only on account of its pvibescence being too 
long to accord exactly with Erichson's description, but also because it 
has been already introduced as British by my friend Mr. G. R. Crotch, 
who has recently, in another place, withdrawn his exponent of it as only 
an abnormal O. dentahis (with any form of which Mr. Sharp's insect 
cannot, however, be possibly confounded), and because the sole repre- 
sentative of it in the European collection of the British Museum* (sent, 
I believe, by Dr. Kjraatz), is without doubt wrongly so named, having 
the anterior angles of the thorax not sufficiently prominent, and not 
acute behind, with the lateral tooth situated above the middle, and the 
punctuation of the elytra not sufficiently strong. Mr. Sharp's insect 
somewhat closely resembles specimens of G. quercinus, Kr., in the Brit. 
Mus. Coll. ; differing, however, from these in its smaller size, the more 
evident contraction of its thorax behind, and the stronger punctuation 
of its elytra. 
* It is somewhat consoling to the " Britisher," often despised by cosmopolitan coleopterists for 
confining his study to the productions of his own country, to find that the extension of range frequently 
entails an extension of error, as proved by the constantly occurring instances of erroneous Continental 
" types," even when sent by the best " authorities." Wishing recently to see Continental specimens of 
Epurtxa variegata, 1 duly received five; whereof one was attiva, and the lemaindcT pusilla. — Ei. C. R.
