Somewhat similar to C. galeahis Fabr., but is considerably 

 larger, the head is unarmed, and in other respects sufficiently 

 distinct. It belongs to the genus Mictis of Leach. 



2. C. ORDINATUS. — Head fulvous, with two black lines ; thorax 

 with the lateral edges fulvous. 



Inhabits the United States. 



Head dull fulvous, with two broad, black, longitudinal lines : 

 antennae fuscous : thorax dull fulvous, with numerous, irregular- 

 ly disposed black punctures, lateral narrow margin fulvous, and 

 with an obsolete interrupted or abbreviated dull fulvous line in 

 the middle ; posterior angles rounded, not promiuent ; posterior 

 margin a little depressed : scutel colored and punctured like the 

 thorax : hemelytra also dull fulvous, with numerous black punc- 

 tures irregularly disposed ; membranaceous portion black : ter- 

 gum on the lateral margin black, the segments fulvous at base : 

 beneath pale fulvous, with a few black punctures : feet with nu- 

 merous black points. 



Length three-fifths of an inch. 



This is one of the most common of our species : when taken 

 it diffuses an odor which has been [319] compared to that of a 

 ripe pear. I have found it in Pennsylvania, Missouri, and 

 Florida. 



3. C. ARMIGERUS [armiger]. — Brown, feet white, spotted 

 with black : head spinous above the antennae ; margin of the 

 tergum black, with five white lineolar spots. 



Inhabits Missouri Territory. 



Body brown above, beneath pale : eyes prominent, rufous : 

 stemmata sanguineous; above the origin of each antenna, an 

 elevated, prominent, acute spine, half as long as the basal joint 

 of the antenna : antennae, first joint white, spotted with black, 

 second and third black, white at base and tip, terminal joint 

 rufous : thorax punctured, elevated behind, descending almost 

 vertically and attenuating to the head; anterior lateral edge 

 dentate, posterior angles dilated and terminated in an angle, 

 from whence the posterior margin descends sinuously and ob- 

 liquely, terminating in a short acute spine each side of the base : 

 base transversely rectilinear: scutel with three black spots at
