area not defined, its sides with a few keels. Teoulse testa- 

 ceous. The hair on the legs is long, dense, and fulvous, the 

 spurs dark rufous. 



Characteristic of this species is the fact that the raised 

 centre of the face and the sides of the clypeus form three 

 large tubercles. In Bingham's arrangement {' Fauna of 

 Erit. India/ Hym. i. p. 459) it comes near N. terminata, Sra. 



Meyachile khasiana, sp. n. 



The pubescence on the head, thorax, and base of abdomen 

 dense, fulvous, on the rest of the back of abdomen and on 

 the apex of ventral surface black ; on the base the ventral 

 scopa black ; legs covered with cinereous pubescence ; the 

 pubescence on the underside of the base of four front tarsi 

 rufous, on the hinder black ; wings fuscous violaceous, the 

 base more hyaline^ paler. ? .

Face and clypeus strongly but not closely punctured, the 

 pubescence on them paler and sparser than on the front. 

 Mandibles widely furrowed along the outer edge ; tlie apical 

 part bordered by a narrow curved furrow, the central with 

 some irregular furrows, of which the apical is the wider and 

 deeper; the apical tooth is long and stout, rounded at the 

 apex, the second is broader and shorter and becomes 

 gradually narrowed to the apex, which is rounded; the rest 

 is broadly bluntly rounded and toothless. Abdomen opaque, 

 closely pimctured ; the basal three segments have transverse 

 furrows near the middle, the apex of the third is more widely 

 depressed. Calcaria testaceous ; metatarsus nearly as wide 

 as the tibise ; apex of clypeus transverse. 



Of the Indian species this comes nearest to M. vmbripennis, 

 Sm., recorded by Smith from Borneo and Nepaul and by 

 Bingham from Sikhim and Tenasserim. The number of 

 mandibular teeth is not given by Bingham, but Smith states 

 (Cat. Hym. Brit. Mus. i. p. 175) that they have four stout 

 teeth, so his species is readily separated from M. khasiana.
