5 . Clypeus short, very broadly rounded at the apex, punctured 

 at the sides, the middle raised and flattened, marked with three 

 very strong longitudinal carinae, with one or two lower carinae 

 between them. Head sparsely punctured, antennae inserted almost 

 as far from each other as from the eyes ; the frontal prominence 

 between them very broadly triangular, bounded laterally by well- 

 marked carinae, at the base by a smooth transverse groove which 

 almost reaches the eyes. Vertex very sparsely punctured, a large 

 smooth space round the anterior ocellus. Pronotum closely and 

 rather coarsely punctured, mesonotum and scutellum sparsely 

 punctured ; median segment closely and coarsely punctured, the 

 surface of the posterior truncation smooth. Pubescence black on 

 the dorsal surface of the thorax and abdomen, more or less cinereous 

 on the sides, very sparse. Abdomen finely and rather sparsely 

 punctured, the dorsal segments with sparse ciliae of black hairs at 

 the apex ; the sixth dorsal segment broadly rounded at the apex, 

 coarsely punctured and clothed with short fulvous setae. Ciliae 

 of the ventral segments sparse and whitish. Third cubital cell 

 pointed on the cubital nervure, the length on the radial nervure 

 equal to nearly two-thirds of the length of the second transverse 

 cubital nervure. Radial cell extending beyond the third cubital 

 cell. Spines of the hind tibiae pointed.

Allied to Scolia (Trielis) punctum, Sauss., but differs 

 much in the colour of the wings and pubescence, and in 

 the less closely striated clypeus. It dififers from techowi, 

 Turn., in the same points of colour, also in the sculpture 

 of the median segment and sixth dorsal segment.

 In Cameron's type the wings are somewhat paler than 

 is usual, but it is undoubtedly identical,
