terior portion in the second and third interspaces, so that there appear 

 to be two additional bhick spots behind the sinuous transverse band 

 above mentioned. The frontal margin is rufous, also the anterior an- 

 gles and frequently the sides of the thorax. 



This species is by no means common in collections, two species only 

 are known to me, one from Pennsylvania and another from the Indian 

 Territory, near Fort Cobb, showing at least a wide distribution.

This species, like (/ranarius, appears to have become almost cosmo- 

 politan, and is abundant over our entire country east of the llocky 

 Mountains. Much of the synonymy of the European authors has 

 been omitted as unnecessary to the object of the present essay. 



From all our species which have the clypeus on each side of the 

 emargination rounded, Inqulnatus may be known by the broad lateral 

 black stripe. The sides and apex are not rufous as in serval. The 

 black spots are, a basal spot at base of fifth interspace, one slightly be- 

 hind this, irregular in outline, occupying portions of the fourth, third 

 and second; behind the middle a sinuous transverse band joining the 

 lateral stripe and extending to the third stria. The head is usually 

 black, the anterior angle of the thorax rufous. 



This species is slightly longer than serval, and occurs abundantly 

 in almost every portion of our country and Europe. 



A. pardalis, Lee. Pacif. R. R. Rep. App. i, p. 41, 1857. — Head black, with ru- 

 fous front and sides, coarsely punctured and rugose near the margins. Thorax 

 more convex than in inquinatus, sides broadly rounded and rufous orrufo-testa- 

 ceous, surface coarsely but stiarsely punctured, with finer punctures between. 

 Elytra somewhat bmader behind the middle, more convex than in inquinatus, 

 pnd more obtuse behind, faintly striate, strije distinctly but coarsely and closely 

 punctured, pale yellowish-testaceous, with black spots arranged as follows; at 

 base of fifth interspace, another slightly behind the scutellum on second and 

 third, another behind this on fourth, and another about the middle on the 

 second and third, a sigmoid transverse patch on the sixth, fifth and fourth, and 

 three lateral elongate spots on the seventh, eighth and seventh again. Body 

 beneath brownish, abdomen, legs and parts of mouth rufo-testaceous. Length 

 .22 inch ; 5.5 ram. 



The series of spots on the disc of elytra are at times confluent, so 

 that they form nearly a semi-circle on each elytron, the lateral spots 

 frequently join and form an irregular stripe, but is always irregular 

 and indicates its origin in the confluence of smaller spots, while the 

 broad stripe of inquinafiiA^ extends along the greater part of two or 

 three interspaces. It may al.><o be known by the sides of the head, in 

 front of the gena3, being slightly sinuous.
