and with a minute projection on each side of the longitudinal median 

 groove at the tip. 



Length (excl. head) 9-lOi, breadth 3|-4i mm. (3 ?.) 



Hab. W. Mexico, Xucumanatlan and Amula in Guerrero, 

 6000-7000 ft. {H. H. Smith). 



Eleven specimens, all females but two, varying in the 

 development of the flavous margin to the prothorax and 

 elytra, which may be almost wholly wanting, and in the 

 colour of the apex of the abdomen, the latter being usually 

 black. Very like D. melancJwlicum, Gorh., but with the 

 prothorax of the male deeply and abruptly notched at 

 the sides at about the basal third, and the elytra explanate 

 at the sides in both sexes. 



41. Discodon funereum, n. sp. 



Elongate, opaque, wholly black, nigro-pilose. Eyes moderately 

 large and prominent in (^, small in $. Antennae very long, some- 

 what dilated, and subserrate in ^, comparatively short and tapering 

 outwards in $. Prothorax {<^) narrow, subquadrate, bicallose on 

 the disc behind, the margins with a deeply-cut angular notch at 

 the middle and parallel thence to the rectangular hind angles ; 

 ($) strongly transverse, broad, the margins reflexed and feebly 

 bisinuate, the hind angles obtuse. Elytra much wider than the 

 prothorax, subparallel, and unusually elongate in cj, explanate 

 laterally and not much wider than the prothorax in $, roughly 

 punctate and feebly costulate. Inner claw of anterior tarsi lobed 

 at base, and outer claw of the other tarsi cleft, in cj- 



(J. Eighth ventral segment oblong, parallel -sided, rounded and 

 reflexed at the tip ; ninth segment feebly trilobed at the apex. 



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



Hab. Mexico, Ciudad in Durango, 8000 ft. (Hoge). 



One pair. The male of this insect is not unlike the same 

 sex of D. carbonariiim, Gorh., from which it may be known 

 by its larger size and rougher sculpture ; the widened, 

 subserrate antennae and the differently-shaped prothorax 

 and tarsal claws of the male, etc. The female is very 

 dissimilar in appearance. Polemius niger, Schaeff ., from the 

 Huachuca Mts., Arizona, described from a single female 

 example, seems to come very near D. funereum and D. 

 melancJwlicum ; but in the absence of the male it is impossible 

 to speak with any certainty.
