RHYNCHITES. 25 
Var.? Major, vix violaceo-tinctus, prothorace ad latera parcius punctato. 
Long. cum rostro 84 millim. 
Hab. Panama, Bugaba (Champion). 
I should have treated this as only a variety of R. championi, but it has a more 
slender thorax, and this part is but little dilated in the male; it differs, moreover, in 
various other slight particulars from that insect. The punctuation of the thorax is 
very fine, but is numerous at the sides. The elytra are flat, and become a good deal 
broader behind, very little punctate, and the white pubescence on the suture and 
scutellum is neither dense nor conspicuous; on the other hand, the white fascia on the 
side of the breast is remarkably distinct. 
We have received seven examples. The variety (?) from Bugaba very likely belongs 
to a different species. 
§ 4. Aberrant species, with rugose sculpture and elongate club to the antenne. 
25. Rhynchites addendus, sp. n. (Tab. I. fig. 20.) 
Parvus, angustus, subtus viridi-niger ; supra seneus, antennis pedibusque sordide testaceis ; capite prothoraceque 
dense rugoso-punctatis; elytris omnino fortissime denseque rugoso-punctatis. 
Long. cum rostro 34 millim. 
Hab. Mexico, Jalapa, Oaxaca (Hége). 
Rostrum longer than the head, shorter than the head and thorax, punctate-rugose ; head 
elongate ; the eyes not large, very distant from the thorax, the surface between them very 
densely and deeply punctate. Antenne inserted at the middle of the rostrum, obscure 
yellow, with the terminal joint darker, the club elongate, each of its joints being con- 
siderably longer than broad ; ninth and tenth joints equal in length, the terminal joint a 
little shorter. Thorax slender, cylindric, slightly longer than broad, excessively densely 
deeply punctate. Elytra with a very deep irregular sculpture, at the base in the form 
of serial punctures, but beyond consisting of deep grooves, interrupted here and there 
in an irregular manner, the interstices narrow. Legs slender. 
We have received only two specimens of this peculiar little species, and they are in 
a very mutilated condition. So far as I can see the characters, they do not fit well 
into any established genus; the pygidium is exposed; the prosternum seems to be 
formed as in Hugnamptus, except that I think the apices of the epimera are contiguous 
and conjoined; the form of the head is very different from that of Hugnamptus; and 
the basal joint of the hind tarsus is about as long as the following two joints together.
