354 SUPPLEMENT. 
Allied to D. substriatus, but smaller, and proportionally narrower ; and to be separated 
from that species by several important characters: the thorax has not the double 
oblique fossa at the base; the elytra are quite distinctly punctate in series of which six 
can be counted on each elytron, but the punctures become confused near the scutellum 
and at the sides, and there is an obsolete row near the suture in addition. The whole 
insect is more shining than D. swbstriatus; the thorax has the same concentric rows of 
muricate tubercles (three or four of these can be counted, behind which the rough 
points become small and confused) as other species of this genus, and the base is 
simply punctate with granular interstices. The antenne differ very strikingly from 
those of D. substriatus, in which they are rufous, and with the two first joints only of 
the club angularly widened internally till they are a little wider than long; in D. per- 
foliatus these joints are so sharply produced as to be more than twice as wide as long, 
and the three last joints are black or nearly so.

Mellié, adopting a name in Dejean’s ‘Catalogue’ for a Madagascar species, viz. 
Aylographus hypocrita, has placed nine species in this genus, three from Madagascar, 
one from Europe and Algeria, and five from Peru and Colombia. It differs from Cvs in 
its general shape, which is more that of Tomicus, also by the extraordinary form of 
its legs, which have the tibie widely lamelliform with denticules on the outer edge. 
In the two species which are here assigned to the genus, the legs agree in these 
particulars, and in addition the femora are wide and compressed, the coxe are elongate, 
cylindrical, and widened at their femoral ends. The prothorax is massive, and projects 
in a singular way over the head. The punctuation of the elytra is coarse and deep and 
rather sparse. 
It is probable that the species now described will, with others from South America, 
ultimately be separated from those from Madagascar, but as I have not dissected 
the European one, which is rare in collections, and of which I have only seen two 
specimens sent me by Herr Reitter, I am not able to point out good characters by 
which they may be separated. In their general peculiarities these species. present 
remarkable affinities with X. bostrichoides, and this is more especially true of X. suillus, 
while X. porcus has superficially a stronger resemblance to a Tomicus, and is evidently 
a near ally of the Colombian X. gibdus.
