84 Mr. G. C. Champion's Revision of the Mexican 



15. Polemius maculifrons, n. sp. 



Moderately elongate, shining, finely pubescent; rufo-testaceous, 

 the eyes, a spot on the vertex, the antennae (the basal joint excepted), 

 an interrupted transverse streak on the disc of the prothorax 

 towards the apex in (J, the base and the apical half of the elytra (the 

 sutural and outer margins excepted) indeterminately in cJ, or their 

 entire surface (the margins excepted) in $, the tarsi in part or en- 

 tirely and sometimes the knees also, and the under surface in part, 

 fuscous or black. Eyes small. Antennae long and slender. Pro- 

 thorax ((J) transverse, binodose on the disc towards the base, the 

 sides strongly reflexed, somewhat rounded, and angularly notched 

 at about the basal fourth, the hind angles obliterated ; (?) broader 

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

 sinuate at the middle and before the obtuse hind angles, the space 

 between the callosities sharply carinate in one specimen. Elytra 

 long, much wider than the prothorax, subparallel, finely punctate 

 and distinctly costulate. Inner claw of anterior tarsi, and outer 

 claw of the other tarsi, lobed at base in (J. 



Length (excl. head) 7-8 J, breadth 2|-3| mm. ((J $.) 



Hab. Mexico, Eeal del Monte [(^ type] and Zacualtipan 

 [$], both in Hidalgo (Hoge). 



One male and two females, the latter having the elytra 

 entirely (the sutural and outer margins excepted) black. 

 Near P. {Discodon) hivittatus, Gorh., but with the lateral 

 notch of the prothorax of the male placed nearer the base 

 and the hind angles obliterated ; the prothorax in the female 

 narrow^ed from near the base and with the margins more 

 sinuate, in this respect approaching the same sex of Discodon 

 erosum, Gorh. The sexes of P. maculifrons are so dis- 

 similar that they might be mistaken for different species. 

 The elytral sculpture is fine, as in P. hivittatus. 



16. Polemius breviusculus, n. sp. 



Comparatively short and broad, finely cinereo-pubescent, shining; 

 black, the anterior portion of the head, the prothorax (except two 

 oval spots on the disc, which are confluent in (^), the scutellum, 

 coxae, and trochanters, the femora to near the tip, base of the tibiae, 

 and the abdomen in part, rufo-testaceous. Head broad; eyes 

 small ; antennae slender, moderately long. Prothorax {^) strongly 

 transverse, rounded at the sides, the latter strongly reflexed and 

 with a deeply-cut angular notch at the middle, the hind angles
