1870.) 9 
differs in its’ rather larger size and lighter color, the more slender basal 
joints of its antenne, and its proportionally rather longer elytra, of which 
the punctures are, though regular and well defined, much more delicate, 
the fourth stria from the suture being, moreover, slightly waved about 
the upper third. 
Xantholinus distans, Muls.; Ktz., Ins. Deutschl., ii, 639. Allied 
to X. tricolor, Fab., but differing from that species, amongst other 
characters, in being smaller, with the thorax reddish behind (not in 
Jront, as in typical tricolor) and having finer and less numerous punc- 
tures in the two dorsal longitudinal striw. I have two specimens from 
Rannoch, one of which has been named for me by Dr. Kraatz. A 
third example agrees in size and coloration with these, but has the 
thoracic punctuation of type tricolor (which also occurred at Rannoch), 
so that Mulsant and Rey’s original reference of distans as a var. of 
tricolor may possibly be correct. X. distans somewhat resembles very 
light specimens of XY. linearis, as Kraatz remarks; indeed, the same 
example that the latter authority named distans for me has also been 
named linearis by M..Fauvel, from which, however, it seems to differ 
structurally. 
Colon denticulatum, Ktz., Stett. Ent. Zeit., 1850, 189; Tournier, 
Soc. Ent. Fr., 4 ser. iii, 151. Corroborated as British for me by Dr. 
Kraatz himself, who states it to be universally exceedingly rare. I 
have a ¢ from Hythe, and there is a 9 in Dr, Sharp’s collection (also, 
I think, in Dr. Power’s cabinet). It is somewhat allied to C. appendi- 
culatum, but is smaller, more convex, and with the posterior femora of 
the ¢ armed only with a small pointed straight tooth beneath. 
I have recently sent a series of the British species of Colon to 
Dr. Kraatz for revision, and have to acknowledge the kind assistance 
of Drs. Sharp and Power and Mr. Crotch. The above is the only 
species new to our list among them, the others being viennense, Hbst., 
Zebei, Kr., dentipes and appendiculatum, Sahl., angulare, Er., rufescens, 
Ktz., serripes, Sahl., brunnewm, Latr., and latum, Ktz.,—all of which 
are corroborated by Dr. Kraatz. ©. puncticolle, Ktz., and calearatum, 
Er., are not known to me as British: they are in our list on Mr. 
Haliday’s authority, I believe. 
Oryptophagus validus, Ktz., Stett. Ent. Zeit., 1856, 240. This is 
the insect named fumatus by M. Brisout, and brought forward by me 
on that gentleman’s authority in Vol. vi, p. 257 of this Magazine. 
Dr. Kraatz himself has named it for me: he compares it to fumatus, 
from which it is evidently distinct. I may observe that Dr. Kraatz 
returns our CO. ruficornis as utterly unknown to him.
