45. Discodon ruflpes, n. sp. 

 Discodon rnfipes, Gorh., in litt. 



Moderately elongate, finely pubescent; nigro-piceous or black, 

 the anterior portion of the head, the basal joint of the antennae, 

 the prothorax and scutellum, the sides of the elytra to near the 

 apex, and in one specimen nearly the basal half of the disc also, 

 and the legs (the tarsi and apices of the tibiae excepted) testaceous 

 or flavo-testaceous. Antennae long and slender in both sexes. 

 Eyes rather small, a little larger and more prominent in cj. Pro- 

 thorax ((^) slightly broader than long, arcuate in front, the sides 

 narrowly and somewhat deeply notched at about the basal third, 

 and parallel thence to the rectangular hind angles ; (?) broader 

 and more transverse, narrowing from near the base, the sides 

 explanate, refiexed, and strongly sinuate. Elytra wider than the 

 prothorax, subparallel in cJ, slightly dilated from a little below the 

 shoulder in $. Inner claw of anterior tarsi broadly lobed, and 

 outer claw of the other tarsi cleft, in cJ. 



(^. Eighth ventral segment oblong, broadly rounded at the tip. 



Length (excl. head) 7^-8^, breadth 3-3| mm. {^ ?.) 



Hab. Mexico, Juquila in Oaxaca (Salle). 



One male and two females. This species looks like a 

 form of D. divisum with the black portion of the elytra 

 showing a tendency to extend forwards to the base. The 

 male, however, has the prothorax more rounded at the 

 apex and the lateral notch much deeper, the antennae 

 more slender, and the eighth ventral segment differently 

 shaped ; the female, too, has the prothorax narrowed from 

 near the base, with the margins refiexed and bisinuate, 

 instead of notched as in the same sex of D. divismn. 



46. Discodon duplovittatum, n. sp. 



Moderately elongate, widened posteriorly, shining, finely pubes- 

 cent; the head between the eyes, the antennae, two vittae on the 

 disc of the prothorax, the legs (except the anterior and intermediate 

 coxae, trochanters, and femora to near the tip in (^), and under 

 surface black, the rest of the surface testaceous. Antennae long, 

 slender. Eyes large in ^, smaller in $. Prothorax ((^) nearly as 

 long as broad, subquadrate, arcuate in front, the sides shallowly, 

 obliquely notched at about the middle and sliglitly divergent 

 thence to the subrectangular hind angles ; (9) broader, with the sides 

 feebly sinuate at the basal third and gradually convergent thence to
