222 RKVISION OF THE TH^NNID.E OF AUSTRALIA, I., 



R. CRASSIPUNCTATUS, 11. sp. 



(J, Clypeus with a median carina from the base to beyond the 

 centre, finely punctured and covered with cinereous pubescence. 

 A broadly rounded carina between the base of the antennae and 

 a transverse one, less distinct than in R. fuscipennis, between 

 the eyes. Head densely punctured, more shall owl}^ and sparsely 

 on the occiput than on the front. Thorax and median segment 

 densely punctured; the anterior margin of the pro thorax \ery 

 slightly raised, the median segment narrowly truncate at the 

 extreme apex. Abdomen finely and densely punctured, the 

 punctures at the base of the segments very minute. An im- 

 pressed transverse line near the base, and a raised smooth mark 

 on each side near the apical margin of segments 2-5. Epipygium 

 rugose. Hypopygium tridentate. Abdomen beneath more 

 sparsely punctured than above. Entirely black, the pubescence 

 cinereous. Wings hyaline faintly tinted w4th fuscous, nervures 

 fuscous. Length 14 mm. 



9. Head large, rectangular, somewhat broader than long, 

 hardly rounded at all at the posterior angles, a short median 

 frontal sulca, the space between the sulca and the eyes longi- 

 tudinally rugulose. The long sulcje from the inner margin of the 

 eye to the occiput approach each other as in R. auriceps. The 

 vertex is smooth and the clypeus is narrowly emarginate at the 

 apex. Thorax smooth, the truncation of the median segment 

 finely and densely punctured. Median segment broadened from 

 the base to the apex, with shallow depressions on tiie sides, 

 leaving a slightly raised central subtriangular space. Abdomen 

 sparsely punctured, the punctures elongate: the first segment 

 short and broad, vertically truncate anteriorly, with a minute 

 tubercle at the base beneath and an oblique triangular trunca- 

 tion at the apex. The epipygium is narrowed before the apex, 

 and has a narrow, smooth, median elevation, the margins of which 

 are raised, forming longitudinal, slightly diverging carinse. 

 Length 1 1 mm.
