236 MR. A. MURRAY’S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 
front. Dull fulvous, with the head, the disk of the thorax, the scutellum, the part of 
the elytra adjacent to it, and the suture, a little darker; finely punctate and pubescent, 
rather dull. The head with a faint semicircular line impressed between the eyes. An- 
tennæ with the club in the female two-jointed. Thorax with the base subemarginate and 
the sides rounded ; slightly margined, the anterior angles a little inflexed and somewhat 
obtusely rounded. Scutellum slightly punctate, obtusely rounded at the apex. Elytra 
long, broadest behind, a little broader than the thorax at their base, with the shoulders 
slightly prominent; the suture slightly elevated towards the scutellum, bearing on each 
side a short subdepressed line; sides margined and almost inflexed, with the apex trun- 
cate and the angles rounded. The pygidium and projecting angles of the pe 
segment alone exposed. 
Found in Canada, Pennsylvania, and other parts of North America. 
There is a species described by Melsheimer (Cercus pusillus) which may possibly be 
the same as this, or Cercus crinitus (see p. 237); but I have been unable to procure 
authentie specimens of it or to identify it from Melsheimer's description, and have con- 
sequently not ventured to adopt his name for it.
