produced in the middle into a point. Head about half aa 

 broad again as long, rounded at the posterior angles, sparsely 

 punctured, the punctures on the front larger and deeper 

 tlmn those on the vertex, a short frontal sulcus, the position 

 of the posterior ocelli indicated by shallow depressions ; 

 eyes narrowly ovate, not reaching the base of the mandibles. 

 Pronotuni fully twice as broad as long, not narrowed 

 posteriorly, the anterior margin straight, with a few seti- 

 gerous punctures, the prouotum and scutellum sparsely and 

 finely punctured, pleurae smooth. Median segment steeply 

 sloped from just behind the scutellum, very finely punctured, 

 with a few larger punctures. Abdomen spai'sely punctured ; 

 first dorsal segment with two transverse carinse at the apex, 

 with a broad groove between them ; second segment with 

 about eight strong but slightly irregular transverse carina ; 

 third segment distinctly transversely striated at the base. 

 Pygidium almost vertical, a little more than twice as long 

 as broad, with a strong spine on each side near the apex, 

 the dorsal plate strongly longitudinally striated, a little 

 shorter than the ventral plate and narrowly rounded at the 

 apex, ventral plate broadly rounded. Fifth ventral segment 

 longitudinally rugose. 



S . Clypeus convex, narrowed towards the apex, which is 

 rather broadly truncate. Antennae longer than the thorax 

 and median segment combined, the apical joints rather 

 slender and very feebly arcuate beneath. Head and thorax 

 finely and very closely punctured, the anterior margin of 

 the prouotum slightly raised. Abdomen fusiform, shining 

 and almost smooth, the segments very slightly constricted at 

 the base ; apical dorsal segment punctured rugose. Hypo- 

 pygiura in the form of a slightly elongate triangle, with an 

 acute apical spine, the basal angles prominent and rounded. 

 Third abscissa of the radius a little longer than the second ; 

 first recurrent nervure received at two thirds from the base 

 of the second cubital cell, second at one-third from the base 

 of the third cubital cell.

This belongs to the group of riifiventris. Guer. ; the male 

 is nearly allied to kirbyi. Turn., and crinitus, Turn., from 

 both of which it differs in colour, from the former also in 

 the somewhat greater breadth of the head and clypeus and 

 the less elongate hypopygium, from the latter in the much 

 stronger sculpture of the seventh dorsal segment and the 

 much sparser and shorter pubescence of the thorax. The 

 female differs from kirbyi in the larger head, the sculpture 

 of the first three dorsal segments, and the greater length of
