41,585, which I boHeve is identical with Or. Ilarrisii. It is smaller than the ICirhian type, being only éf lines
long-; the head is very convex and rugosely punctured; the mentum deeply notched. The prothorax, according
to a drawing which I made of it in 1869, is gradually widened from the emargination in front of the
posterior angles towards the head; the sides are but slightly curved, the anterior angles outwardly rounded,
incurved, and porrected with a deep impression within tlie angle. The disc is ñnely puncturcd, and in the
centre is a slightly depressed line. The elytra are thickly variolose, the punctures being generally oval. It
only bears the vague locality, ' Amer. Septentr.'

deeply sinuated at each side in front of the posterior angles; the sides curved and gradually narrowed towards the head;
each side deeply impressed within the anterior angles ; a central furrow and the hind angles produced and eleviitod ; the
head is swollen in the middle of the disc, forming two circular raised moderate elevations ; the middle tibiie are thick ;

This species is nearest in appearance to 0. canaMculakis, but smaller, with the fovea at the anterior angles
of the thorax larger, and the punctures smaller. The scales of the punctures, both on the thorax and elytra,
readily distinguish it. The incision of the mentum is narrow.
SPECIES 7 (93)—CBEMASTOCHEILUS JUNIOR.
(Schaum, MS ; Verz. Lam. Melit. p. 64.)
PLATE XIV, PIG. 8.
The late Dr. Schaum, in his letters to me in 1847 and 1848, mentioned a new species which he had
received from Zimmerman (which he sent to me for delineation), inhabiting South CaroHna, to which the latter
had applied the name of Or. junior; a name adopted in MS. by Schaum, but not occurring in his collection of
these insects now preserved in the Hoyal Museum of Berlin. Nor is there any specimen agreeing with such
a species (from South Carolina) with a slightly notched mentum, if wo except the one numbered 41,577, whicb
I believe to be identical with Or. cicatrkosus. The specimen sent to me by Dr. Schaum for delineation is
represented in pi. XIV, fig. 8, and may possibly be identical mt h the Or. sqmmuloms of Leconte.
I t is black, moderately glossy, clothed with very short thick whitish seta;; the body beneath is covered with
shallow circular punctures emitting short scaly setie; it is convex, and not transversely or longitudinally impressed
in the basal segments. The notch in the middle of the hind margin of the mentum is narrow.

My figure of this species is engraved from a drawing by Wagenscbieber, kindly sent mc by Dr. Schaum,
who described it as ' not only very beautiful, but also very correct.' The mentum is concave, with a slight
notch in the middle of the hind margin.
The descriptions of Schaum and Burmeister above referred to (given as variolosus K.) were both taken
from specimens in the Germar and Halle Colleotions, sent from Say (as from North America), and from Zimmerman
from South Carolina.
' The species is easily distinguished by the very slight notch of its mentum. The drawing of the latter,
made by Wagenscbieber, is correct; that of Guérin, in Gory's boot, is erroneous, Guerin having entirely
overlooked the incisura. I liave carefully compared the specimeu in the Museiun of Halle, from which I and
Burmeister took the description. In my own description it is mentioned that the mentum has but an extremely
slight incisura (p. 257), that the sides "of the thorax are rounded, and that the punctures of the elytra bear
yellow hairs. I remember perfectly well that this was the insect which Harris had under the name of
variolosus Kirhj; he was therefore perfectly right in considering this species as distiuct from Saiji, but wrong
in considering it as variolosus Kirhj.' (Schaum in litt. 20 Oct. 1848.)
