tropics. The occurrence of the same species in Africa and South America is a 
remarkable feature in their distribution. The whole family, and especially the larger 
species, need careful revision, when perhaps some further explanation of this anomalous 
fact may be hoped for.

The species of Apate have the most intimate affinity even when from distant parts of 
the world; and their close resemblance makes their determination very difficult. I am 
at present uncertain whether more than one species exists in Mexico; for, although I 
have a second species so labelled in my own collection, it does not accord with the 
characters given by Horn for A. fortis, Lec. 
The present species may be recognized by the acuminate dentiform points in the 
front margin of the thorax being approximate and nearer together than the eyes, and 
also by the funiculus of the antenne, composed of the third to the seventh joints, being 
much longer than the three terminal ones, with the joints themselves bead-shaped, 
longer than broad. The apex of the elytra is declivous; in the specimen labelled 
A. deflexa there are two acute callosities; but in most of the specimens there is merely 
an abrupt termination of the convexity of the elytron leaving a sort of round callus ; 
the interstice nearest the suture is faintly raised. In the other species which I possess 
referred to Mexico, the antennal funiculus is shorter than the club, and scarcely longer 
than the second joint; its joints are strongly transverse and connate. 
BOSTRYCHUS. 
Bostrichus auctorum nec Geoffroy, Hist. Ins. p. 301. 
The type of Bostrichus is B. capucinus, Linn., as reference to Geoffroy makes apparent, 
which is an Apate. This is therefore one of those instances in which, if the rule of 
priority be observed, a long-established and generally received genus must be suppressed. 
I here adopt the name for those species which have the elytra more or less tubercular 
or costate, and the labrum distinct from the clypeus, and therefore in the same sense 
in which Mr. Horn has used it for the North-American species found in the United 
States. In the Munich Catalogue, under this generic name, are included many true 
Apate ; but, restricted as above, I have not seen species I should include excepting 
from the New World. ‘The presence of hind angles or more or less truncation of the
