226 HETEROMERA. 
OZOLAIS. 
Ozolais, Pascoe, Journ. Ent. ii. p. 457 (1866) ; Ann. & Mag. Nat. Hist. 4th ser. viii. p. 851 (1871). 
A single species only, O. scruposa, Pascoe, from the Amazons, was originally placed in 
this genus by the describer, the same author subsequently (Ann. & Mag. Nat. Hist. 
5th ser. xi. p. 437) adding two others, 0. divisa and O. gibbera, from the same locality ; 
we have now to add four more from Central America. In one of these, O. elongata, 
the antenne are 11-jointed, or rather the last two joints, which are more or less connate 
in the other species, exhibit a distinct dividing suture (though closely articulated 
and formed much as in Calymmus); in O. lutosa the suture is indicated, and in 
O. nodosa also, but very indistinctly ; in O. verrucosa there is no visible suture. This 
character alone, judging from the material before me, unless supported by other 
characters, can scarcely be considered of generic value. In the male of some 
species, O. elongata, O. nodosa, &c., the head is armed with a conical tubercle 
in the middle of the epistoma in front and a transverse elevation (prolonged 
into a horizontal flattened plate, the apex of which is widened on each side, in 
O. elongata) on the vertex. Ozolais is nearest allied to the North-American genus 
Bolitotherus, Cand. (= Phellidius, Lec.), from which it will be readily known by the 
clavate antenne; the entire upper surface, as in Bolitotherus, is coarsely and irregularly 
tuberculate and densely clothed with greyish-brown scale-like hairs; the elytra in 
some species, O. verrucosa and QO. divisa, exhibiting rows of impressions which are — 
plainly visible between the elevations. 
1. Ozolais verrucosa. (Tab. X. fig. 9.) 
Broad, subparallel, brownish-black, the upper surface coarsely tuberculate and clothed with scale-like hairs. 
Head with several small scattered conical tubercles between the eyes, the antennary orbits swollen and 
rounded ; antenne 10-jointed, ferruginous, the first joint long and stout, the second small and short ovate, 
elevations coarser and more numerous, the rows of punctures more irregular and more shallowly 
impressed ; tarsi long. 
Length 94-11} millim. 
Hab, Ecvanvor (Buckley). 
Two examples in Mr. F. Bates’s collection. 
Calymmus vestitus, sp. n. 
Closely allied to C. variegatus; the prothorax formed almost as in that species, the posterior angles subrect- 
angular, the horn wider at the apex (the apex concave within); the elytra with the ridges as in 
C. scabriculus (but formed of more rounded and more distantly placed elevations), the rows of punctures 
very coarsely impressed outwardly, shallower towards the suture; tarsi shorter and stouter than in 
C. variegatus and C. scabriculus, 
Length 103-11 millim. 
Hab, Perv, Chanchamayo; Brazit (coll. F. Bates). 
Two examples.
