([x73.] 229. Cacuinium simite Avrby.—Length of body 7 lines. 
A single specimen taken with the preceding species. 
_ This species in most respects is so like C. 47. Proteus, that I had set it 
by as another variety ; but upon further consideration I am induced to 
give it as distinct, since it differs not only in colour but in the form and 
sculpture of the prothorax and other parts. 
The apex of the palpi is more dilated, so that it is strictly securiform ; 
the front behind the antennae is elevated and gibbous, with few scattered 
punctures: the sides of the prothorax are more puffed out, and much 
more minutely and thickly punctured, and there is a pair of impressions 
‘in the disk : the antennae also at the base are rufous: in other respects it 
does not differ from JZ, Proteus. 
[This species, together with the preceding and the subsequent one, 
belong to the genus Phymatodes Muls. It is probably another variety of 
the very variable Proteus, as it has not been identified by any author that 
we are aware of. | 
230. CALLIDIUM DIMIDIATUM A7zréy. Length of body 4 lines. Two 
specimens in Lat. 54°. 
Body not glossy ; impunctured ; hairy underneath; and except the 
forebreast, which is black, of a dull rufous. Head channelled between the 
eyes, behind them convex ; antennae rufous, shorter than the body: pro- 
thorax somewhat coarctate at the base; minutely granulated ; obsoletely 
channelled, more conspicuously behind : elytra rufous anteriorly. 
This species comes very near to C. (Merium) Alni, but it is larger and 
has no white bands. 
[CLyTus PALzLrATUS Hald. is a later synonym of this species. It is 
taken in Canada and the Eastern States; also on north shore of Lake 
Superior by Agassiz’s Expedition. | 
[174.| Sub-genus TErroprum Xvrby.—Eyes four, connected by an 
elevated line. Antennae robust, short: scape much incrassated, subcy- 
lindrical, remaining joints subclavated. Prothorax constricted anteriorly 
and posteriorly. Thighs much incrassated, sometimes clubbed.
