M. viduatus, St. ; Er., I.e., p. 185. Also determined as British by M. Brisout 
specimens sent by Mr. Crotch and myself. It may be known from M. 
ularius by its lighter antennee, the more rounded sides of its thorax (which is 
ely so closely punctured), its more abruptly broadened hinder tibisB, and its 
ir broader anterior tibiffi, the apical teeth of which are sharper and longer. 
M. pedicularms, (Gyll. ?) Er., I.e., p. 186. In the collections of Messrs. Crotch 
Bold and Dr. Power. Determined by M. Brisout. The anterior tibiae are very 
bly widened, with the entire outer margin toothed, the denticulations being 
ger towards the apex, the last but one most prominent. 
M. bidens, Brisout, Gren. Cat. et Mat., p. 52. The M. ]pedicularius of Wat. 
must be referred to this species. It differs from the pedieularius of Erichson 
sing rather smaller and narrower, less convex, duller and more finely and 
[y punctured (the punctuation at the base of the elytra being very delicately 
versely rugulose) , and in having its anterior tibiae mnch more widened towards 
pes, which is armed with (usually) only two well defined teeth. This species 
nmon at Mickleham, on Teucrium scorodonia. 
W. ovatus, St. ; Er., Lc, p. 198. Determined as British by M. Brisout from 
mens sent by Mr. Crotch and myself. It is very like M. viduatus (though 
iated with M. flavipes), but of a shorter ovate form, with the thorax more 
)tly narrowed in the apical third, and the tibiae broader, — the armature of the 
ior pair being less defined. 
M. lidentatus, Brisout, I.e., p. 61. Determined by M. Brisout from two speci- 
in Mr. Crotch's collection. The species is allied to M. erythropus, but ia 
r wider and more convex, with closer punctuation, wider tibiae, and a bi- 
kte projecting transverse keel at the extremity of the last abdominal segment 
kf. ebeninus. Crotch G3A,.=^lugubris, Sturm. 
If. obscurus, Crotch Cat., is now referred by M. Brisout to M. palmatus, Er. 
nsect is not uncommon at Mickleham, and is, I think, the distinctus of Wat. 
It does not seem to me to agree precisely with the descriptions of any of 
species. 
If. marrubii, Bris., Crotch Cat., still unique (I believe) as British in Mr. 
h's collection, is allied to M. serripes, but is larger, with stronger punctuation, 
^er thorax, and the armature of the anterior tibiae stronger and less regular. 
'. intend to communicate a further series of types to M. Bi-isout, and will 
sh the result of his investigation. 
Lathridius constrietus, Gyll., Ins. Suec, iv, p. 138. I have a single British 
men of this curious insect. It is allied to carinatus, but is rather smaller, 
wer, and of uniformly lighter colour, with the thorax especially longer and 
wer, and divided as it were into two lobes, of which the anterior is much the 
r, and very rounded at the sides, with no trace of any angle in front. The 
ointed club to the antennae, on which Thomson founded his genus Coninomus 
>aatz, Berl. Ent. Zeit., xiii, p. 129)^ readily separates these two species from 
allies. L. constrietus is sunk in De Marseul's Cat. (L'Abeille) as a syn. of 
tiis, Forst. (the latter name again appearing by itself at the end of the genus !) ; 
iccording to Kraatz, I.e., it is carinatus, Gyll., that is identical with Fiirster's 
es. Mannei'heim attributes L. constrietus to Britain, evidently through his
