the base of the mandibles, the sides of the prothorax broadly, and 

 about the basal third of the elytra {(^), or a humeral streak {$), 

 ochreous or rufo-testaceous. Eyes small. Antennae moderately 

 long, broadly dilated and subserrate, rajiidly tapering outwards. 

 Prothorax {^) strongly transverse, arcuate in front, parallel-sided 

 from the narrow oblique lateral notch, which is placed at about 

 the basal fourth, to the rectangular hind angles ; ($) simply sinuate 

 before the base, and with the sides arcuately converging thence to 

 the apex. Elytra moderately dilated from a little below the 

 shoulder, rugulosely sculptured and conspicuously costate. Inner 

 claw of anterior tarsi broadly lobed, and outer claw of the other 

 tarsi cleft at tip (the outer section of the claw shorter than the 

 inner), in S- 



Length (excl. head) 8:^9, breadth 3-3| mm. (J ?.)

One pair, the female with the elytra infuscate, the 

 humeral streak excepted. These insects were left by 

 Gorham under D. histrio, which was from the same localities 

 in Guatemala, and labelled by him Discodon sp. The 

 broadly dilated, rapidly tapering antennae, the short pro- 

 thorax, with the lateral excision of the male placed much 

 nearer the base, etc., readily separate D. subnlicorne from 

 D. histrio. The elytra vary in colour, as in the species 

 described by Gorham under the names Silis varians, 

 serrigera, etc.

(^. Eyes large; antennae long, joints 3-11 moderately dilated, 

 subserrate, tapering towards the tip; prothorax a little broader 

 than long, arcuate in front, obliquely compressed on each side of 

 the disc anteriorly, the margins deeply notched at the middle, and 

 subparallel and scarcely reflexed thence to the subrectangular hind 

 angles ; anterior and intermediate tarsi dilated ; inner claw of an- 

 terior tarsi strongly lol)ed at base, the outer claw of the other tarsi 

 cleft at tip.
