396 Dr. J. L. Leconte's Synonymical Notes 
as the range of C. vulgaris is very extensive, and it is subject 
to much variation. I have previously viewed this race, un- 
known to me in nature, as a doubtful synonym of C. pane 
Dej., a very different insect, which is itself a race of C. formos 
Say ; afterwards, believing it to be distinct, I proposed for it b 
name of C. Kirbyi (Proc. Acad. Nat. Sc. Philadelphia, 1866). 
2. Elaphrus Clairvillei, Kirby. According to the type, this 
is the species afterwards "described as E. politus, Lec. 
. E. intermedius, Kirby, is not the large Kansas species, 
with a broad and strongly constricted prothorax, which I had 
determined as such, but a smaller one, of the size of Æ. ruscarius, 
Say, from which it differs by the prothoracie and mesothoracie 
pleure being more finely and densely punctured. It seems to 
be one of the races which, in the ‘ List of Coleoptera of North 
America,’ I have grouped under Z. californicus, Mann., over 
which name it has priority. 
Kirby. he only specimen is in very bad 
condition ; it ausis the Meta E. obliteratus, Mann., but 
is much smaller. 'The elytra are very feebly and sparsely 
punctured, the ocellate i impressions are shallow, and there are 
two or three polished subsutural spots * 
nchomenus angusticollis, Kirby; afterwards described 
as An t stygicus, Lec. ed di has no resemblance 
e European P. angusticollis; and it was probably from 
ina confusion of labels that it was so referred by Mr. Kirby- 
6. Agonum seminitidum, Kirby, =A. cupreum, Dej 
chalceum, Lec. A common species in tbe Lake- uper 
region. 
7. A. affine, Kirby. A rather stout and convex species, 
rad ‘ferent from any in my collection 
8. A. simile, Kirby. A small, narrow, ‘slightly bronzed 
species, De the legs and antenne black. The Alaskan A. 
fragile , Which I saw in Baron Chaudoir's collection, 
closely aaa it, and probably belongs to the same species. 
A. ery thropum, Kirby. As far as can be determined 
from the specimen, which is in very bad condition, this is 
Platynus subcordatus, Lec., a very abundant species in the 
regions beyond Lake Superior. 
10. Argutor bicolor, Rabe The head is wanting in the 
specimen ; but, from the form of the prothorax and the di- 
stinct scutellar strie, it belongs to the Argutor division of 
Pterostichus, and does not differ from P. patruelis (Dej.). 
l. A. brevicornis, Kirby, is a small Prerostichus of the 
iL bate seen in the same collection a specimen of E. 1a labelled 
« c America,” which is quite undistinguishable from European
