Hymenoptera Orientalis. 453 



Salius Rothneyi, Sp. nov. 



Black, pruinose ; eyes a little diverging beneath, straight- 

 Ocelli in a triangle, separated from the eyes by a somewhat 

 greater distance than they are from each other. Clypeus 

 a little projecting towards the apex, which is broadly 

 rounded and margined. Occiput transverse, rounded at the 

 sides. There are two broad ridges above the antennae, 

 having a smooth, shining fovea between them. Head 

 opaque, finely and closely punctured ; the clypeus has the 

 punctures distinctly separated, and it is more shining. The 

 cheeks and clypeus bear a close silvery pubescence and 

 some long silvery hairs ; the vertex bears long fuscous 

 hairs. Mandibles finely punctured at the base ; the apex 

 piceous. Pronotum short, in front obliquely transverse 

 laterally ; behind arcuate. Median segment shorter than 

 the mesothorax, broadly and gradually rounded ; thorax 

 opaque, finely and closely punctured ; median segment 

 towards the apex transversely striolate ; the central furrow 

 indistinct. Abdomen shining, indistinctly pruinose ; the 

 apical segments finely punctured and covered with longish 

 fuscous hairs ; the terminal segment acute at apex ; the 

 petiole at the base about one third of the width of the apex. 

 Antennae shortish, pruinose. Wings hyaline, with a slight 

 fuscous tinge ; a cloud at the basal nervure ; a broader one 

 extending from the apex of the stigma to near the apex of 

 the radial cellule. Second cubital cellule obliquely quadrate ; 

 at the top one-half longer than the third at the top ; at the 

 bottom a little shorter. The first recurrent nervure is 

 received in about the apical third of the cellule ; the second 

 distinctly before the middle. Legs pruinose ; the long 

 spur of the hind tibiae reaching to the middle of the meta- 

 tarsus ; the tibial spines stout, the central very thick, 

 somewhat triangular at the apex, the metatarsal brush long,
