Trichoplus schaumi, Westw., 

 Thesaur. Entom., 33, pi. ix., fig. 10. 



Black, sub-opaque, clypeus deeply depressed on the anterior part 

 on each side, and also deeply emarginate in front, strigillate longi- 

 tudinally, frontal part foveolate punctate, vertex with a very 

 distinct, slightly rounded transverse keel ; prothorax broadly 

 ampliate rounded from the anterior part to about the median 

 and produced thence to the base in the shape of a truncate cone, 

 the base being only one-third of the greatest width, the anterior part 

 of the disk is greatly raised, almost vertical and in the centre is a 

 very deep almost orbicular excavation the sharply emarginate walls 

 of which coalesce slightly past the median part with the sharply 

 carinate outer margins, the sides of the excavation are strigillate, the 

 anterior part of the excavation is also strigillate but the median and 

 posterior are deeply foveate punctate, each puncture bearing a short 

 greyish bristle ; scutellum covered with broad, reticulate punctures ; 

 elytra with the epimera very sloping, and about as wide at the 

 base as the prothorax at its widest part, sub-parallel but a little 

 ampliated laterally behind, the suture is moderately raised and there 

 is on each side a sharp dorsal costa, set nearer to the raised suture 

 than to the deflexed lateral part, the whole surface is covered with 

 sub-longitudinal strioles which are, however, more diagonal on the 

 sides of the suture, and in the striae are seriate but somewhat remote,, 

 very short, sub-flavescent hairs; propygidium foveate punctate, 

 slightly carinate longitudinally in the centre, and having a fringe of 

 glandular hairs ; pygidium vertical but with the upper margin pro- 

 duced into an horizontal lamina emarginate in the centre, and 

 greatly overhanging the vertical part the base of which is covered 

 with yellowish glandular hairs springing from elongated, strigillate 

 punctures ; the sides of the abdominal segments are similarly but 

 more roughly punctured and the two last segments bear laterally the 

 same kinds of flavous hairs, the legs are aciculate, greatly com- 

 pressed, the pectus is punctulate, and the ante-coxal process is 

 triangularly truncate.

Black, moderately shiny, hairless, antennae piceous red ; clypeus 

 of the same shape as T. scliaumi, but carinated in the centre on 

 each side of the anterior depression, and having on the vertex a
