B. »/y5-icorms, Ferruginous ; antennse black ; 
elytra blackish-blue. 
Inhab. Missouri, 
Body ferruginous, with short hairs : head with 
irregular punctures each side between the anten* 
nse, becoming irregular, but slight, lineations near 
the eyes : antennm brownish-blue, first and second 
joints ferruginous : thorax with minute, irregu- 
lar, transverse lines, dorsal lines well impressed ;; 
elytra slightly grooved, more obviously so to- 
wards the base ; edges beneath, purplish ) post* 
pectus^ except in the middle, and venter blackish, 
with short, whitish hairs. 
Length seven-twentieths of an inch. 
Var. a. Sutural edge of the elytra ferruginous.. 
I obtained this species in the winter of 1819, 
when with Major Long’s party at Engineer Can- 
tonment near Council Bluff. It occurred in consi- 
derable numbers, occupying some crevices of rock, 
eight or ten feet under the surface, in a tempora- 
ry euarry, where they were hybernating. , It dif- 
fersfrom cyanipennis^ Say, found at the same Ip-: 
cality, by the different colour of the antenii®, &c. 
Can this be the janus^ or is the quadripennU, 
Dej., synonymous with that species, described is

1. C hipustulatay Fabr. The true species of 
this author, has almost always, if not in every 
instance, but _two spots on the elytra, and these 
are terminal." The second interstitial line has 
seven or eight subequidistant punctures, arid the 
fourth interstitial line has five or six punctures, 
subequal, excepting the terminal one which ii 
more distant. . 
2. C. quadrimaculatusy Palisot de Beauyois.— 
This species is quite distinct, though very cjbsri- 
ly allied to the hipustulata. It is similar in siaaa 
and almost so in form ; but the thorax is prppdr^ 
tionally longer In colour it is generally like the 
preceding, but in addition to the two termirial 
punctures of the elytra, their base is more or less, 
but generally obsoletely, tinged with obscure ru- 
fous. The interstitial lines are altogether desti- 
tute of punctures., I have a variety iri my Qolieo- 
tion, of which the elytra are entirely of a rrifpus 
colour and even paler than the terminal spots usu- 
ally appear ; these spots are of course not visible* 
b. C. vmdis, Say. Trans. Amer. Philos. Soc*, 
has been since described by Dejean uridef t'H# 
name ofrosfra/a, Sp. Gen. 1, 419, but corrected 
vol. 2, Supp. 478. 
Of this genus I have eight described speCiei ^

1. C. vinctusy Weber. I thirik it highly pro- 
bable that Dejean is right in eonsidering, aa h* 
does (doubtfully however) my C. iriterruptus, to 
be the same as this. . Weber’s expression, “ linein
