LARIDES.—CYLINDROCOPTURUS., 30 
and posterior pairs compressed, tibial claw long, third tarsal joint short, broadly bilobed, tarsal claws 
small; body elliptic, robust, squamose. 
Type, L. cavifrons. 
The single species referred to this genus is nearly related to Phileas, differing from 
it in having the eyes less acuminate below and more widely separated above, the 
antennal club shorter and relatively stouter, and the prothorax and elytra subtruncate 
at the base. 
1. Larides cavifrons, sp.n. (Tab. III. figg. 3, 3a, 3.) 
Oblong, subovate, nigro-piceous, the antenne and the tips of the tarsi ferruginous; thickly clothed with small 
pale brown and whitish scales, the prothorax and under surface with larger scales, the intra-ocular space 
ochraceous, with a small fulvous spot on each side, the whitish scales on the elytra condensed into two 
interrupted fascie, the posterior one subapical, the anterior one angulate and with an oblique ramus 
extending forwards to the base of the second interstice, the triangular space between the common, 
A-shaped mark and the short apical declivity fulvous spotted with black, the femora variegated with 
whitish above. Rostrum rugulosely punctate to the tip, finely carinate. Prothorax about one-half 
broader than long, rounded at the sides, narrowed and strongly constricted in front, the anterior lobe 
tubulate, the posterior lobe rather convex and with a very sharp median carina in front; densely punctate. 
Elytra wider than the prothorax, gradually narrowing from a little below the base, the produced apical 
portion short, bluntly rounded ; finely punctate-striate, the interstices broad, 3, 5, 7, and 9 more or less 
raised and undulate. Ventral segment 5 depressed in the middle at the apex. 
Length 33, breadth 12 millim. (<.)

One specimen, in perfect condition. 
CY LINDROCOPTURUS. 
Cylindrocopturus, Heller, Abhandl. Mus. Dresd. no. 11, pp. 4, 56 (1895). 
Paratimorus, Heller, loc. cit. pp. 4, 58. 
Copturodes, Casey, Ann. N. York Acad. Sci. ix. pp. 667, 669 (1897) * 
A genus including numerous representatives from the Southern United States and 
Mexico, and an aberrant form from Guatemala. The new species now added show 
that Paratimorus cannot be retained, the longer and straighter rostrum of P. gangl- 
bauert being a character of no importance and probably peculiar to the female sex. 
The Mexican representatives, like those of North America, are densely clothed above 
with coarse, overlapping scales, rounded on the elytra and oval or oblong on the 
prothorax, which almost hide the sculpture. The unarmed femora &c. separate 
Cylindrocopturus from Timorus. An allied monotypic genus, Gyrotus, with acute 
post-ocular processes to the prothorax, has been described by Casey; it is from 
California. 
* The name Copturodes has already been sunk as a synonym, ¢f. Casey, Canad. Ent. 1904, p. 324.
