592 Mr. T. Vernon Wollaston on the 
structure. Indeed in its thickened head, abbreviated, 
subtriangular rostrum, and depressed eyes, no less than in 
its greatly shortened antenna3 and its long and slender feet, 
the genus has very much the sub-Hylastideous aspect of 
Steiioscelis : and it may be defined therefore to differ 
essentially fi'om Rhyncolus in its much shorter and more 
triangular rostrum ; in its larger and more sunken eyes, 
which are appreciably less lateral (or more sub-approxi- 
mated above) ; in its prothorax being altogether more 
cylindrical and developed ; in its very much more abbre- 
viated antennae (the sca])e of which is so reduced in length 
as to be even shorter than that of Stenoscelis, — indeed as 
short as in the European genera Stereocorynes and Hexar- 
thrum, or as in Calyciforus and Eurycorynes from Brazil), 
the club of which, although compressed, is exceedingly 
rounded, solid, and abrupt ; in its first and second abdo- 
minal segments being much more conspicuously divided 
from each other; in its legs and tarsi being slenderer 
(with the tibial hook more straightened, and the basal 
joint of the latter rather more elongate) ; and in its coxfe 
being more approximated,— the four hinder ones, in fact, 
being nearly contiguous. In its scutellum however being 
conspicuous, Brachytevinus recedes from Stenoscelis, and 
agrees better with the other immediately-allied forms. 
120. Calyciforus (?iou. (yen.). — The very extraordinary 
insects, which have been communicated by jNIr. Fry and 
Mr. Janson, for which the present genus is established, 
and which were captured in the provinces of liio Janeiro 
and Bahia in Brazil, are amongst the most remarkable 
members of the Cossonidce with which I am acquainted ; 
and yet their affinities arc, unquestionably, with such forms 
as the European Bracliytemnus, Eurycorynes from Brazil, 
and Stenoscelis — fi-om S'. Helena, Southern Africa, and 
Japan. Indeed in its thickened head, short, subtriangular 
rostrum, and sunken, subajjproximated eyes, as well as in 
its excessively abbreviated antenna?, its slender, filiform 
feet, and the fact of its four anterior coxa3 being nearly 
contiguous, the genus has much marvellously in common 
with the first of those groups ; nevertheless the compara- 
tively large size of its members, and the deep and anoma- 
lous triangular excavation in the middle of their prothorax 
behind (immediately in front of the greatly developed 
scutellum), added to the extraordinary sculpture of their 
elytra (the sulci of which are wide, deep, opake, and
