of the former species; but it is rough and rugose, instead of 
being shining and more or less smooth. 
Apparently more numerous than the preceding species of this 
section, but still received only in very small numbers. 
§ 2. Thorax with anterior angles not prominently projecting. 
The species in this section have not the same facies as the pre- 
ceding species. They are large, coarse, black insects, with much 
more real affinity to the genus Apate than to the species of the 
present section, which contains the, smaller Bostrichi, such as 
B. varius, Ilig. (Dufourti, Latr.), &c. Indeed the distinction 
between Apate and Bostrichus (as that genus is now defined by 
Lacordaire) would better rest (according to my judgment) on 
the facies of the insects than on whether the antennz have the 
club compact and close or open and loose. There are all 
degrees of difference in this character to be found in the spe- 
cies forming the two genera; and I should have preferred that 
Apate had been reserved for all the large, coarse, black species, 
while Bostrichus was kept for the smaller ones. But few genera 
can be so well defined as to escape criticism, at least when the 
contain more than one species; and to attempt to aiuctarl 
Lacordaire’s arrangement now would be a much worse evil than 
to preserve some incongruous or ill-characterized genera. A 
fixed arrangement that we all know and can refer to as a 
standard is what we have wanted for thirty years past, what 
Lacordaire’s ‘Genera’ was started to supply, and what that 
wonderful work has most successfully accomplished. 
4. Bostrichus brunneus. 
Angustus, brunneus; thorace duobus parvis dentibus uncinatis, 
antice projicientibus, et post hos quatuor vel quingue lineis 
transversis dentium minorum; elytris lineatim punctatis, 
hneis irregularibus vix strias formantibus, apice rotundato sat 
abrupte declivo. 
Long. 3+ lin., lat. 1 lin. 
The species in question is narrow, dull, and brown. The head 
is finely papillose or granulated, with a shallow transverse 
furrow across the front between the eyes, wider and tumid 
behind this depression ; in the middle of the depression there is 
a short, transverse, slightly raised, smooth line; there is a little 
fulvous pile on the front of the epistome; the margin of the 
labrum is also fringed with fulvous pile. The thorax is as broad 
as long, widest in the middle, sinuate before‘ the posterior 
angles, which are slightly prominent; the anterior angles are 
rounded, and terminate in front in two short but rather pro-
