and Central American Telephorinae. 55 



the apex. Elytra wider than the protliorax, moderately explanate 

 from a little below the shoulder, roughly punctate and distinctly 

 costate. Inner claw of anterior tarsi broadly lobed, and outer claw 

 of the other tarsi cleft at tip, in cJ. 



Length (excl. head) 7-7 J, breadth 3-3i mm. (cJ ?.) 



Hab. Mexico {Truqui, ex coll. Fry, Mus. Brit.). 



One pair. Not unlike D. hiridum, Gorh., but much 

 smaller and narrower, the prothorax bivittate (as in D. 

 hivittatum), the elytra distinctly costate and much less 

 explanate, the outer claw of the intermediate and posterior 

 tarsi cleft at the tip in (^, the prothoracic notch of the (^ 

 placed at the middle. From the similarly-coloured variety 

 of D. hivittatum the present species may be known by the 

 differently-shaped prothorax, with less refiexed margins, 

 the form of the tarsal claws, etc. 



47. Discodon testaceipenne, n. sp. 



(J. Moderately elongate, widened posteriorly, shining, finely 

 pubescent; black, the sides of the head in front, the base of the 

 mandibles, the prothorax (a median vitta excepted), and elytra 

 testaceous. Eyes rather small. Antennae nearly as long as the 

 body, somewhat widened, serrate, slightly tapering outwards. 

 Prothorax nearly as long as broad, arcuate in front ; the sides 

 abruptly, obliquely notched just behind the middle, and gradually 

 divergent thence to the prominent hind angles, appearing obtusely 

 dentate in front of the emargination. Elytra wider than the pro- 

 thorax, gradually widened from a little below the shoulder, costate 

 on the disc. Inner claw of antei'ior tarsi broadly lobed, the outer 

 claw of the other tarsi cleft. 



(^. Ninth ventral segment oblong, trilobed at the apex, the central 

 portion narrowly produced, leaving a slender, obliquely projecting 

 spine visible on each side. 



Length (excl. head) 6|, breadth 2| mm. 



Hab. Mexico, Ventanas in Durango {Edge). 



One male. Very like the same sex of D. duplovittatum, 

 but with a single vitta on the prothorax and the lateral 

 notch deeper (appearing angulate in front of the emargina- 

 tion), the head and eyes smaller, the antennae broader and 

 more distinctly serrate. It is much smaller and narrower 

 than the similarly coloured D. luridum, Gorh., and has 

 the prothoracic notch placed further forward and the 

 outer claw of the intermediate tarsi cleft.
