it joins the epistoma, its length in the middle about half its breadth; 

 epistoma almost triangular ; fore-chest granulated, with a ferrugi- 

 nous ridge in front and along the upper side, prolonged into a some- 

 what ascending, very slightly curved, compressed, tapering, but 

 hardly pointed horn whose length is more than twice the depth of 

 the fore-chest above the head ; on each flank of the horn are five 

 irregular ferruginous ridges, the upper one is forked near the tip of 

 the horn and extends backward to tlie lower border of the fore-chest 

 near the tip, the other four are indistinctly forked in front and are 

 successively more short ; fore-chest tapering backward nearly to the 

 lip of the abdomen, very slender towards the tip which is pointed ; 

 upper side and lower side of the hind horn nearly straight ; disk of 

 the latter hollow : abdomen black towards the base ; plates at the 

 tip large, punctured: legs pitchy ; thighs black; feet yellow: fore- 

 wings lanceolate, lurid, punctured towards the base; fore border 

 slightly convex ; hind border straight till near the tip where it is 

 slightly convex: hind-wings almost colourless. Length of the body 

 4^ lines ; of the wings 6 lines.

Body ferruginous: head granulated; front not widening to- 

 wards the mouth, slightly convex on each side, concave to somewhat 

 less than half its length where it joins the epistoma, its length in 

 the middle rather less than half its breadth ; epistoma transversely 

 elliptical: fore-chest granulated, with a ridge in front and along 

 the upper side, 'prolonged into a horizontal, hardly curved, com- 

 pressed, tapering but not pointed horn whose length much exceeds 

 the depth of the fore-chest above the head ; on each flank of the 

 horn are four ridges ; the upper one is strongly marked and extends 

 from the tip backward to the lower border of the fore-chest a little 

 beyond the base of the Ibre-wing ; the other three are short, slight 

 and oblique ; fore-chest tapering backward to the tip of the abdo- 

 men, lurid and slender towards the tip which is pointed ; upper side 

 and lower side of the hind horn almost straight, disk of the latter 

 hollow : legs and tip of the abdomen lurid : fore-wings lanceolate, 

 brown, not punctured; fore border slightly convex; hind border 

 straight till near the tip where it is slightly convex : hind-wings
