o4 RHYNCHOPHORA. 
PHILEAS, gen. nov. 
Antenne inserted at the middle of the rostrum, joints 1 and 2 of the funiculus equal in length, 3-7 shorter, 
decreasing in length, the club ovate, with joint 1 about as long as the others united; rostrum stout, 
arcuate, short, not longer than the prothorax as seen in profile; eyes oval, somewhat pointed beneath, 
distant, the intra-ocular space widening upwards; prothorax short, deeply bisinuate at the base, truncate 
at the apex, without definite ocular lobes, the basal lobe subtruncate ; scutellum exposed ; elytra about one- 
half wider than the prothorax, sinuate at the base, blunt at the apex ; pygidium not visible; mesosternum 
vertical, flat, the metasternum extending forwards between the coxe to meet it; ventral segments 
ascending, 1 and 2 convex, 2 at the sides about as long as 3 and 4 united; legs short and stout; femora 
unidentate, the intermediate and posterior pairs compressed, the posterior pair earinate on their outer 
edge, tibial claw long and stout, third tarsal joint short, broadly bilobed, tarsal claws small; body robust, 
sparsely squamose. 
Type, P. granulatus. 
A single species from the mountains of Western Mexico—the unique example of 
which has been injured in an attempt to pin it, owing to its very hard integument—is 
referred to this genus. The short rostrum, prothorax, and legs, the broad elytra, the 
widely separated eyes, the shorter first joint of the antennal club, &c., separate it 
from Timorus. 
1. Phileas granulatus, sp.n. (Tab. III. figg. 2, 2a, d.) 
Subovate, broad, robust, black ; the vestiture rather sparse and fine, denser and almost entirely ochreous on 
the head, rufo-ferruginous on the prothorax and rostrum, and rufo-ferruginous intermixed with cinereous 
on the other portions of the body, as well as upon the legs, the elytra each with an oblique yelvety-black 
patch on the suture below the base (the two patches united forming a A-shaped mark) and a small black 
spot in a line with the lower part of it near the margin, the latter preceded by an indefinite transverse 
ochreous patch ; the intermixed cinereous scales on the elytra and under surface minute and hair-like, 
the red scales small, oval, those on the prothorax elongate. Head densely punctate, depressed between 
the eyes ; rostrum densely, rugulosely punctate to the tip, finely carinate down the middle. Prothorax 
rather convex, strongly transverse, rounded at the sides, narrowed in front, densely, rugulosely punctate, 
the anterior portion tubulate, the posterior portion sharply carinate. Elytra about one-half wider than 
the prothorax, somewhat dilated at the sides below the base, and gradually narrowing thence to the 
apex, flattened on the disc; with sinuous rows of small punctures, the interstices rugulose, more or less 
raised, and subseriato-granulate (except near the anterior part of the suture), 3, 5, 7, and 9 rather more 
prominent than the rest. Beneath and the legs densely, rugulosely punctate. 
Length 6%, breadth 33 millim. (2?)

LARIDES, gen. nov. 
Antenne inserted at the middle of the rostrum, joints 1 and 2 of the funiculus equal in length, 3-7 short, the 
club stout, ovate, with joint 1 as long as the others united; rostrum stout, arcuate, short, barely longer 
than the prothorax as seen in profile ; eyes elliptic, distant, the intra-ocular space concave, subtriangular, 
rapidly widening upwards ; prothorax short, feebly sinuate at the base and apex, with broadly rounded, 
feeble, ocular lobes; elytra short, subtruncate at the base, blunt at the apex; pygidium not visible ; 
mesosternum declivous, unimpressed ; intermediate coxe widely separated ; ventral segments ascending, 
2 about as long as 3 and 4 united; legs short and moderately stout, femora unidentate, the intermediate
