 " ? . 34 mm. Abdomen, 26 mm. Colour light rusty red, . . . 

 smooth and shining. Antennae with 10-jointed flagellum. Head 

 quadrate but rounded, the median dorsal groove is deepest behind, 

 and very shallow on the vertex. The frontal carinae almost reach to 

 the anterior margin of the clypeus, which lies between them in the 

 shape of a small triangle. On the anterior portion of the vertex, the 

 median groove forms an oval, well-defined and strongly punctured 

 pit [i.e. the depressed area between the frontal carinae. — G. A.]. 

 The posterior corners of tbe head are obtusely triangular and pro- 

 duced backwards. The upper surface of the head is finely but 

 distinctly punctured, more sparsely so behind than in front, the 

 latter region being slightly dull owing to an exceedingly fine sub- 

 puncturation. . . . The prothorax is wider at the shoulders than at 

 the posterior margin. . . . The mesothorax is flattened, very 

 shallowly impressed in the middle in front, punctured like the 

 prothorax, but more strongly than the head, nevertheless distinctly 

 shining. The metathorax is also depressed, with a transverse 

 groove on the compressed anterior portion, and the posterior part 

 is slightly swollen on each side; the segment is more finely and 

 sparsely punctured than the pro- or mesothorax. The femora and 

 tibiae are punctured ; the last three joints of the tarsi wanting in all- 

 the legs. First abdominal segment wider than long, trapezoid, 

 3rd-6th segments longer and wide and parallel-sided. Hypopygium 

 two and a half times longer than wide, with a transverse furrow- 

 shaped impression along three-fifths of its length on each side; 

 narrowed posteriorly and forked in the middle of the posterior 

 margin by a deep oval excision, the two arms of the fork long and 

 obtusely triangular, and flat. The surface of the hypopygium, 

 excepting its base, is finely punctured, between the lateral furrows 

 and the median excision fairly densely punctured. The 5th dorsal 

 segment is longer than the 4th, but ends before the fork of the 

 hypopygium, its posterior margin on each side wide and flat, in the 

 middle narrow and deeply emarginate, so as to form on each side of 

 the emargination a triangular and projecting point. At the base of
