C. Belfraget, Salle. This species not very largely represented in 
collections, occurs from the middle of July to the middle of September. 
It is very peculiar in its habits, I first took a specimen July 6th, 1883. 
while mowing grass. Something clogged the sickle, and I got off to 
look after it, when a beetle darted from under the fallen swath into the 
standing grass. I gave pursuit, and in a few minutes had the first spe- 
cimen of C, Belfragei in my collecting bottle. A few days afterward in 
company with my friend, Mr. Warren Knaus, we put in an afternoon 
collecting in the meadow. We walked up and down the field, fairly 
melted with the sultry heat, for two or three hours with no success, when 
at last, about four o’clock, I caught sight of one darting across the 
road a few feet ahead of us, and during the next hour we captured five 
specimens. They are rarely found during the heat of the day, but like 
the Zétracha, are crepuscular. Iam satisfied that they have no burrows 
of their own as I have taken several specimens by overturning hay cocks. 
And I have never taken them at an altitude of fifty feet above the Smoky 
hill river bottom. 
 C. scutellaris, Say. Occurs abundantly in limited localities in sandy 
ravines among hills during May and June. 
C. purpurea, Oliv. Common here, is probably too well known to 
all Coleopterists to need any description of its habits. 
Var. Auduboni, Lec., is found in the same localities as C. purpurea. 
Var. splendida, Hentz. The earliest species found in the spring; I 
took two specimens Feb. 28th, 1883. This variety is notable for its 
great variation in markings. I have several times observed them with a 
large bug, (Zygacus ¢rivitta/us), in their mandibles, 
C. venusta, Lec. Rare, taken in company with S. scufellaris in the 
same season. 
C. vulgaris, Say. Is found occasionally on sandbars in the river. 
C. repanda, Dej. Abundant in same localities as the last. 
C. 72 guttata, Dej. Frequent; prefers very wet and muddy spots 
on sandbars, and I have several times observed them swimming across 
small pools. 
C. punctulata, Oliv. Abundant everywhere from July 1st to the 
middle of September, at all times of day, from daylight unti] dark and 
occasionally they fly to a light at night.
