(i-) 
Inhab. near the Rocky Mountains. 
Body black“brown. punctured, with 
short hairs r head - - - : thorast de» 
i::idedly ti’ansverse, with numerous, 
somewhat large punctures ; truncate 
before, and a little sinuate behind ; — 
margin each side depressed and a lit- 
tle elevated, dull rufous ; at the pos- 
terior an obvious tooth : elytra with 
very slender, capillary striae in which 
are minute punctures, which are 
larger and more obvious towards the 
base and lateral margin ; interstitial 
lines with a very slight convexity, 
and with numerous, small punctures, 
rather larger than those of the stria ; 
lateral margin obscure rufous ; tip 
truncate, without any appearance of 
sinuation; beneath obscure rufous, 
punctured: feet rufous; thighs and 
trochanters paler. 
Length about two-fifths of an inch. 
I obtained it when on the expedi- 
tion to the Rocky Mountains with 
Major Long. The thorax is shaped 
somewhat like that of americana, 
Dej., but is wider as in platicolli% 
Say. The elytra have not the slight- 
est appearance of being sinuated at 
tip.

This species has been since described 
by Dejean, under the name of margimUai 
V. Spec. Gen. 1, p. 222, but corrected 
vol. 2. Supp. p. 450. 
He has given the name of 
to another species ; but as it is a subse- 
quent name, he will of course change it, 
2. C. smaragdina^ Dej. A specimen 
of this insect was sent to me by Dr. Pick- 
ering, from Salem, Massachusetts, so that 
it is probably a general inhabitant of the 
Atlantic U, S., but as I have found it my- 
self but once, (in the state of Ohio,) I 
should suppose It is rare.

2. L. viridist Say, Trans. Amer. Philos* 
Soc. Dejean has described a species un- 
der the same name. It is clobely allied 
to, if not the same as this, but if not the 
same species, the name must of course be 
changed. Spec. Gen. 1, 271, 
3. L. Jmcata, Dej, varies in having the 
head nearly black, the thorax yellowish 
ferruginous, and the elytra paler brown, 
with the yellowish spots, parUcularly the 
terminal® almost obsolete. 
(The following genus should have been 
inserted between the genera Amblychei- 
laandCicindela.)

M. caroUnOt Fabr, This species is cer- 
tainly found in die southern part of the 
Union : I have an individual that was ta- 
ken near New Orleans, it varies a little 
from West Indian specimens in being less 
deeply sculptured,
