mesotliorax scutelliim and postseiitellum above silvery-gray ; the wings 

 smoky- hyaline, tlie tegulas andnervures testaceous-brown ; the legs black, 

 the anterior and intermediate legs and the coxae and trochanters of the 

 posterior pair with reddisli-brown pubescence getting paler on the tarsi, 

 the outside of the femora and tibijsof the posterior legs black and shining, 

 the inside clothed with a dense short ferruginous-brown pile. The abdo- 

 men black with long black pubescence, the penultimate segment with a 

 silvery-gray band above, the apical segment ferruginous-brown ; below 

 the abdomen is destitute of pubescence, piceous-black and finely pitted. 



This species was first sent to me from Kumaon. Subsequently I 

 found it sparingly distributed above 8,000 ft. in Sikkim on Senchal 

 and Tiger Hill near Darjeeling, and at Guntok and Sedonchen in Native 

 Sikkim. Named after my friend Mr. F. MoUer, who has done so 

 much for the entomology of Sikkim. 



5.-MEGACHILE STELOIDES, n. sp.,Pl. I, Eig. 5, ?. 



Habitat : Sikkim. 



Female : Length 13 man,, expanse 28 m.m. 



Male : Unknown. 



Desckiption : 9 . Black, the two apical segments of the abdomen 

 and the tibiaa and tarsi of the legs testaceous-yellow ; the scutellum 

 projecting backwards and completely overhanging the metathorax as 

 in Stelis. Head as broad as the thorax, shining, very finely pitted ; 

 mandibles black quadridented, very broad at the tips : clypeus large, 

 oval, slightly convex, its anterior margin bisinuate; antennse piceous; 

 the back of the head flat, the ocelli placed in a broad triangle on the 

 vertex. Thorax very densely and coarsely pitted, the mesanotum 

 bearing three short longitudinally impressed Hues not reaching to 

 its posterior margin, the scutellum in shape like that of the species 

 of Stelis projecting backwards and overhanging the metathorax, its 

 posterior margin rounded and notched in the middle ; wings hyaline, 

 the apical margins broadly but lightly infuscated, tegulse and nervures 

 dark brown; legs black, the outer margins of the femora, the tibia3 and 

 tarsi rich ferruginous-brown. Abdomen black and shining, finely 

 pitted, the two apical segments and the pollen-brush bright ferruginous. 



This remarkable bee, which probably deserves generic separation, 

 1 found frequenting flowers and the wet sand along the banks of the 

 Run jit river in Sikkim in May. In habits it is a true leaf-cutter bee.
