52 HETEROMERA. [ Salpingus. 
referring to S. e@rafrs, all the localities above given have been recorded as for S. ater, 
but I believe that they must be referred to thepresent species, if S. eratus and S. ater 
are really distinct. 
S. ater, Payk. As far as I can make out, this species can only be 
said to differ from S. @ratus in its colour, which is deep shining black, 
with the legs also black, the tarsi being more or less pitchy, and the 
base of the antenne reddish ; it is said to differ in the impressions of the 
thorax, and in the fact that the elytra sometimes have a fovea near base, 
but these are quite unreliable characters; the elytra also are said to 
have the rows of punctures regular to base, but they are quite as regular 
insome specimens of S. ¢ratus ; in fact the latter species differs con- 
siderably in punctuation, and in the case of two type German specimens 
from Herr Reitter now before me, one has the thorax considerably more 
strongly punctured than the other; in a type specimen of S. ater sent 
me by the same entolomogist the thorax appears to be a little more nar- 
rowed behind and more even and regularly punctured than is the case 
with the general run of S. @rutus, but in all points, including colour, 
shape and punctuation, intermediate examples appear to occur, and I 
feel strongly inclined to regard the species as synonymous, and merely 
varieties of one species. L. 25-3 mm, 
Of all the specimens I have seen one only appears to be related to the 
type S. ater, and this was taken by Mr. Champion at Aviemore, Inver- 
ness shire. 
S. mutilatus, Beck. (virescens, Muls., nec Lec.; s.g. Colposis, 
Muls.). In general appearance somewhat resembling at first sight a 
specimen of Rhinosimus planirostris ; greenish-bronze, very shining, 
with the mandibles long and exserted, the labrum and other mouth parts 
reddish-testaceous, and the antenne fuscous with reddish-testaceous 
base, gradually thickened towards apex ; eyes very prominent; thorax 
short, subcordiform, rather diffusely punctured; elytra with shoulders 
well marked, much broader at’ base than base of thorax, with sides 
slightly dilated and rounded behind, and with rather regular rows of 
moderately strong punctures, and an impression on each befure base ; 
legs testaceous, L. 2-23 mm. 
In dead twigs, &c.; rare; it has only been taken at Caterham and at Gomsball 
near Dorking by Mr. G. C. Champion ; in the former place he took a few examples 
by sweeping Mercurialis perennis under old beech trees in the autumn. 
This species is distinguished from the three preceding by the long 
exserted mandibles, the broadly flattened and almost concave frontal 
region of the head, the shorter thorax and more strongly impressed 
elytra, the very shining upper surface, the greenish-bronze colour, the 
reddish-testaceous labrum, &e.; and from S. foveolatus, which it more 
nearly resembles in the structure of the mandibles, by the shorter and 
narrower rostrum, the differently coloured oral organs, the flattened 
frontal region, the differently formed labrum, the smaller size, the more
