Heliocopris marshalli, n. spec. 



Male : Head and prothorax black, opaque, elytra black, shining ; 

 head strongly plicate in front, scrobiculate behind, genae emarginate 

 laterally and dilated at apex where they form a triangular strongly 

 developed tooth, base angular, clypeus aculeate laterally at about 

 the median part, a little emarginate, margin slightly reflexed, in the 

 anterior part of the head is a short, sub-cylindrical, hook-like horn, 

 vertical for two-thirds of the height and curved behind from there, 

 behind this hook-like horn are three raised carinas arranged in the 

 shape of a triangle, the wide part of it reaches the base ; prothorax 

 ■deeply and confluently scrobiculate, truncate in front, deeply but 

 narrowly excavate laterally, and with the anterior angles not pro- 

 jecting, these lateral excavations are smooth, and reach the outer 

 angles, and the median part is produced into a broadly triangular 

 lobe carinate laterally, somewhat similar in shape to th2;t of H. satyrus 

 and H. hamadryas, but instead of the apex of the triangle being 

 sharp or obtuse, it is divided into two sharp sub-horizontal, sub- 

 cylindrical, parallel horns, 4 mm. long ; elytra narrowly but deeply 

 striate, intervals slightly punctulate, punctures numerous and some- 

 what close to each other, no basal tubercle on the intervals ; pygi- 

 dium closely but not deeply punctate ; metasternum with a deep, 

 broad, basal impression and a short, median sulcus. 



Female unknown. 



Length 36 mm. ; width 22^ mm.

Piceous black, with the elytra dark brownish-red, shining ; head 

 transversely plicate in front, transversely rugose behind, both 

 sexes with a high transverse laminate carina truncate on each side ; 

 prothorax transversely scrobiculate in the anterior part, and covered 

 with elongate granules in the posterior part, which granules are 

 replaced on the sides by scrobiculate very irregular punctures ; elytra 

 narrowly punctulato-striate, intervals aciculate ; pygidium closely 

 punctulate ; metasternum with a deep, broad basal impression, and a 

 short, faint longitudinal impressed line. 



Male : Genae lanceolate, clypeus a little concave in front, elongate, 

 moderately acuminate, a little rounded laterally and slightly sinuate
