lustre ; the scutellum, postscutellum and metathorax slightly raised, 

 the last convex with its apical margin distinctly recurved, and fine 

 almost obsolete transverse striations ; wings dark brown, with an 

 oblique sub-hyaline yellow band crossing the middle ; the legs have 

 the coxse trochanters, basal half of the femora, and the last joint of 

 the tarsi with the claws dark brown, the apical half of the femora, 

 the tibiae and the basal joints of the tarsi bright ferruginous red, the 

 tibiae and tarsi have a few scattered spines. Abdomen silky black, 

 smooth and shining. 



$ resembles the 9 , but the ferruginous red of the head and 

 prothorax is of a lighter tint, inclining to yellowish, the mesothorax, 

 scutellum, postscutellum and metathorax are silky black, the last 

 with coarse well marked transverse striations, the wings are as in 

 the $ , but altogether of a lighter paler shade, and there is a dark 

 brown opaque spot in the centre of the 2nd discoidal cell ; the tibiae 

 and tarsi very slightly spinose ; the abdomen slightly flattened, 

 vertically. 



This species was common in March and April in the Pegu hills, 

 hunting about among the fallen leaves at the bottom of dry streams 

 in a restless, hurried manner. I found its nest, a burrow in the 

 ground at the roots of a large fern, and watched it storing the same 

 with a small and very pretty species of cockroach brown with yellow 

 markings. The conspicuous and brightly- coloured tibiae and tarsi of 

 this insect are very remarkable, giving it somewhat an appearance 

 as if it had breeches on.
