Hah. Mexico {Truqui, in Mus. Brit.). 



Six specimens, the females differing very slightly from 

 the males, the exact locality not recorded. An elongate,

14. Trichochrous riifitarsis, n. sp. 



cj. Elongate, subcylindrical, shining ; aeneo-piceous, the antennae 

 black, the tarsi rufo-testaceous, except at the tip ; sparsely clothed 

 with fine pallid hairs intermixed with numerous long, erect, bristly 

 hairs. Head densely punctate, the epistoma flattened; antennae 

 rather long, joints 5-10 transverse, broad, triangular, 5 a little larger 

 than 6, 11 stout, elongate, acuminate-ovate. Prothorax convex, 

 roimded at the sides, narrowed anteriorly, closely punctate. Elytra 

 slightly wider than the prothorax, subparallel in their basal half, 

 conjointly rounded at the tip; closely, coarsely punctate. Fifth

Hab. Mexico, Oaxaca (Hoge). 



One male. Recognisable amongst the allied forms by 

 its rufo-testaceous tarsi, rather long, sharply serrate 

 antennae, with stout, acuminate apical joint, the closely 

 punctured, convex prothorax, and the numerous intermixed 

 erect bristly hairs on the upper surface. The sheath of the 

 aedeagus (exposed in the type) is strongly curved, stout, and 

 cyUndrical, and acutely pointed at the tip beneath.
