Allied to R. fuscijjennis Sm., from which it maybe distin- 

 guished by the densely punctured abdomen of the male, and the 

 shape of the head and sculpture of the median segment in the 



female. 



R. GRACILIOR, n.sp. 



^. Clypeus longitudinally carinate at the base, the carina 

 branching in the centre, the branches enclosing a triangular space 

 reaching to the apical margin, which is emarginate at the apex, 

 A broadly V-shaped carina between the antennae, and a transverse 

 frontal carina reaching to the eyes. Clypeus punctured, covered 

 with grey pubescence, fulvous between the carinse. The space 

 between the frontal carinas rugulose; occiput shining, with large 

 shallow punctures. Thorax shining, sparsely covered with 

 shallow punctures. Scutellum subacute at the apex. Median 

 segment rounded, densely and finely punctured at the base, 

 delicately reticulate towards the apex, with white pubescence on 

 the sides. Abdomen sparsely punctured, the punctures large and 

 shallow, the base of the segments Yevy delicately punctured, 

 beneath more densely punctured; segments 2-6 above with a 

 depressed transverse line near the base, and a raised space at the 

 sides near the apical margin. Epipygium rugose, rather broadly 

 rounded at the apex. Hj'-popygium without lateral spines, aculeus 

 with a blunt tooth on the upper surface. Black, the mandibles 

 at the apex, and the legs, excepting the cox£e, obscure fuscous. 

 Wings fusco-hyaline, in some specimens almost hyaline. Length 

 14 mm. 



5. Head longer than wide, rounded at the posterior angles. 

 Clypeus rugulose; front above the antenna? with fine golden 

 pubescence, densely punctured and with a m^^dian sulca. A 

 narrow lateral sulca reaching from the inner margin of the eye 

 to the occiput in an almost straight line, the sulcai not convergent. 

 Thorax sparsely punctured, median segment only slightly 

 broadened posteriorly. Abdomen sparse!}^ punctured, the first 

 segment longer above than beneath, narrowed from the apex to 

 the base, produced at the base above, overlapping the oblique 

 truncation of the median segment, which is clothed with golden
