Heliocopeis marshalli, n. spec. 



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

 head strongly plicate in front, scrobiculate behind, gense 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 carinse 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 that of H. satyrus 

 and H. liamadryas, 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.

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 ;

 with elongate granules in the posterior part, which granules are 

 replaced on the sides by scrobiculate very irregular punctures ; elytra

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

 short, faint longitudinal impressed line.
