82 HYMENOPTEEA. 



one lower down in the middle. There is a blunt tooth on the posterior coxae at the 

 apex above ; teeth on the femora large, black, except at the base ; the basal one is thicker 

 and stouter than the others, which are as long as one fourth of the breadth of the femora ; 

 they become a little longer towards the apex. Like the body the legs are covered with 

 black hairs.

Flagellum about double the length of the scape, thick, increasing in thickness 

 towards the apex, closely covered with a fuscous pile; beneath it is faintly reddish. 

 Scape not carinated, moderately thick. Excavation on front deep, black beneath the 

 ocelli; behind the head is black in the middle. Mesonotum coarsely punctured, 

 mesopleura in middle striated in centre of depression, outside around it smooth, 

 impunctate; the rest coarsely punctured, but not so strongly as above. Scutellum 

 also coarsely punctured, margined behind, depressed in the centre. From the pro- 

 notum run four broad black bands towards the scutellum, but only the two inner ones 

 reach it ; in front of the scutellum is a black transverse band narrowed in the middle ; 

 at the side of the scutellum, behind the tegulse, and in its centre is a small black mark. 

 In front the mesopleura is black, as is also the central depression, and the metasternum 

 is black. Metanotum reticulated, its sides straight. Posterior coxae nearly as long as 

 the femora, ovoid. Teeth on the femora large, curved, directed towards the apex ; two 

 apical smaller and blunter than the rest, and nearly united at the base. The knees 

 and apex of the posterior tibiae are brownish fuscous. The abdomen is unfortunately 

 missing from the only specimen I have.

This species has eight acute teeth like S. octodentata, but the body is entirely 

 yellow, and the mesonotum transversely striated. The abdomen is described as shortly 

 pedunculated.
