C. Crotchi is described as very like versicolor, Ch. Bris. (quercicola, Wat. Cat.), 
but differing from that species in its more depressed prothorax, of which the 
anterior margin is less reflexed, and in its testaceous tarsi, with smaller claws.-—ID. 
Note ow Monotoma 4-dentata, Thoms.—Thomson, Opusc. Ent., p. 3338, in de-| 
scribing this supposed new species, compares it only with M. picipes, which he! 
states it to resemble very much in size and build, but to differ from it in its hea 
being shorter before the antenne, its obsolete frontal foveole, its rather shorter 
prothorax, of which the basal foveole are more shallow, but the lateral denticles! 
near the base are more prominent, and its narrower and more strongly tranarerl 
rugulose elytra, of which the sides are scarcely dilated. | 
These differential characters are so precisely those of M. brevicollis, Aubé, that!

description of this species in Ent. M. Mag., V, p. 183 (Nov. 1868), no further; 
examples of it have come under my notice until the end of May in the present) 
year, when about six specimens were taken by the Rev. H. 8. Gorham and Dr. 
Power at Bearsted, near Maidstone, off Scrophularia aquatica. Two others also} 
were soon afterwards taken by the former of those gentlemen, near Staple, Kent: | 
by promiscuous sweeping. These latter agree with my insect as described, but all! 
the Maidstone specimens materially vary therefrom in coloration, and render an| 
addition to my description necessary. Instead of being lurid testaceous with the. 
under-side, head,-and apex of antennz and of posterior femora pitchy, as were all 
the examples formerly known to me, these (or, at least, the most fully marked of | 
them) are entirely black beneath, with the head, scutellum and hind femora (except’ 
at the base internally) black, and with the suture of the elyira narrowly edged with 
black for its basal sixth, then broadly so until the apical sixth, where the black: 
almost entirely vanishes. There is also in some of them an indeterminate pitchy 
patch on the lateral margin near the point where the posterior femora touch the | 
sides. The posterior tibia are distinctly, and the 5 apical joints of the antennz 
more or less, pitchy. The spurs of the posterior tibiz in all the above mentioned | 
specimens are exceedingly small and short, broad at the base, and scarcely per- } 
ceptibly cnrved at the apex. 
The coloration above described naturally causes a reference to T. lateralis, Ill. ; 
but that species (which could hardly have failed to be familiar in all its phases to}

elytra have a very projecting humeral callus, with their punctuation disposed in.

in the others, &c. 
T. sutwrata, Foudr., found on Verbascum thapsus in the south of Europe, has 
shorter spurs than T. lateralis, but they are still arched; the punctuation of its 
thorax is almost imperceptible, and of its elytra very fine and disposed in almost 
straight lines in the upper half, &c.—Ip.
