sion is that of a shining species, which was certainly not 
intended. The thorax is a little short, otherwise the form 
coincides with the species which is figured herewith. 
The cinereous base of the rostrum is an important character, 
as it signifies that a considerable portion of the base is coated 
while in cariosus it is not. The cross-like elevation of the 
thoracic disc is aptly described as feebly indicated, in fact is 
requires a little imagination to discern it in many individuals ; 
moreover, it is not shown in Olivier's figure. In the true 
cariosus the cross is black, shining and well-marked, and the 
cariniform base of the third elytral interval which is always 
present is so prominent as to attract the attention of the 
veriest tyro. 
The type locality "Carolina" will answer for either species. 
North Carolina appears to be the metropolis of callosus. 
Sphenophorus cariosus Olivier. 
Sphenophorus sculptilis Uhler, Proc. Acad. Nat. Sci. Phila., 1855, p. 416 
As the original description of sculptilis may not be acces- 
sible to many, it is transcribed below together with italicized 
words of my own and brackets to indicate portions of the 
description which are not specific. 
Entirely black, elevated portions shining; thorax with a sphenoid, poste- 
riorly acuminate, medial, and two undulating, prominent elevations. 
8^ lines long to tip of rostrum. Baltimore. 
Black punctured; rostrum, rather robust, finely punctured at base 
sulcated [and dilated immediately in front of base; club of antennae, 
whitish at tip; thorax round, constricted in front, and slightly dilated 
a little before the middle], densely and coarsely punctured at sides, and 
between the elevations, puncta becoming finer anteriorly; scutel deltoid, 
excavated; elytra with two elevated, interstitial lines, a prominent elongated 
tubercle each side behind the humerus, and a round one near the apex 
of each elytron, sutural lines slightly elevated; [the three medial, and 
subsutural ones a little punctured at base; pygidium somewhat coarsely 
punctulate, punctures becoming finer at base; legs finely punctulate, 
patella more coarsely so; a large deep fovea upon the base of the post- 
pectus, posteriorly; venter with gradually enlarging punctures, increasing 
in size toward the base]. 
After carefully comparing several species with this descrip- 
tion I have come to the conclusion, in the absence of a knowl- 
edge of the whereabouts of Uhler's type, which cannot be 
located and may be destroyed, that it was based upon a some- 
what unusuallylarge specimen of 5. cariosus, which measure some- 
what less than "8^ lines" including the rostrum. Horn, in his
