NEW AND LITTLE-KNOWN SPECIES OF 201 



IND 0-MA L A YA N HYMENOPTERA . 



of the genus Salius. In colour S. audax is a much deeper richer red than 

 S. nicevillei, and this difference holds good through a series of six 

 specimens of S. audax and eight of S. nicevillei, Sikkim specimens of 

 this latter insect vary very much, being considerably smaller with 

 conspicuously more dusky wings.

Description, — $. Head, thorax and abdomen black with ferrugi- 

 nous-brown marking^. Mandibles ferruginous, darkening to brownish- 

 black at the tips, clypeus lighter brown, oval, boldly convex and 

 covered with a fine thin ferruginous pile, the face below the antennas 

 on the inside of the eyes yellow, scape of antennse ferruginous, 

 llagellum black, forehead, vertex, and cheeks black and shining, sparse- 

 ly studded with black hairs, ocelli placed in a broad triangle on the 

 vertex. Thorax, the prothorax light ferruginous-brown darkening to 

 fuscous-black below, anteriorly it is rounded, its posterior margin 

 arched or widely angled ; rest of the thorax, pectus and pleurse dark 

 fuscous-black, the scutellum and postscutellum marked with light

 in some extending more or less into the radial and 2nd cubital cells 

 in the forewing and even into the radial and medial cells of the 

 hindwing. In the forewing the transverse-medial nervure rises well 

 before the apex of the 1st submedial cell, and the 1st recurrent nervure 

 is received in the apical third of the 2nd cubital cell ; in the hindwing 

 the cubital nervure is interstitial, rising at the apex of the anal cell ;
