This is a large, robust species; the mentum is entire, saucer-shaped, round in front, and obtusely pointed 
in the middle of the hind margin (fig. 3a). The front margin of the head is rounded, elevated, smooth, and 
glossy; the dise of the head scabrous; the prothorax has the sides very much rounded, it is one-half wider 
than long, the widest part being behind the middle; the dise with a very slight abbreviated central furrow, 
the punctures close and fine, emitting short setze; the anterior angles foveated internally, the posterior angles 
acute, scarcely elevated, not separated from the dise by a deep impression, the base bisinuate, faintly impressed 
on each side; the elytra are nearly flat above, sparingly punctured with large elliptical shallow fove, from 
which proceed short bristles: the legs are short, the tarsi very short. The body beneath is black and glossy, 
and finely punctured. 
My figure of this species is engraved from a beautiful drawing by Wagenschieber, kindly sent to me by 
Dr. Schaum. 
Major Parry possesses a Californian specimen, 7+ lines long, which I believe must be referred to this species, 
which has extremely short thick legs, the fore tibie with the two outer teeth almost obsolete, the tarsi not 
more than twice the length of the tibial spurs, and the elytra faintly marked with irregular delicate luteous 
transverse striole. If ultimately proved to be a distinct species, it may receive the name of Cr. crassipes.

‘Closely allied to Cr. Mexicanus Schaum, and as flat as the latter, but a little smaller. The under lip has no 
trace of an incisura, but is a little produced behind. The angles of the clypeus are more rounded, the head 
more densely punctured, the thorax much more coarsely sculptured, especially at the sides; the lateral margin 
crenulated. It is less attenuated in front than in Cr. Mexicanus, the incisura on the inside of the anterior angles 
much deeper, the anterior angles more produced, and a little turned inwards. The scutellum is smaller, 
narrower at the apex, and more acuminated. The elytra are much more coarsely and densely punctured at the 
sides, and on the dise transversely rugose. The spiracles of the antepenultimate segment are smaller; the 
pygidium much more coarsely and densely sculptured.’ (Schaum MS, in letter of 4th Sept. 1849.) 
My figure of this species is engraved from a drawing kindly sent to me by Dr. Schaum. His typical 
specimen is now in the Berlin Royal Museum, No. 41,581. The dise of the head is closely covered with sharp 
small punctures ; the anterior margin rounded and raised ; the punctures of the prothorax emit small sete. It 
is black beneath, evenly punctured, and finely setose, the setee arising from the punctures. 
This species is distinct from Cr. Knochii, judging from a specimen from Illinois from the Schaum Collection
