longer than wide, of equal width rounded at the apex. The hair all over is 

 long and dense; on the back of the abdomen it is pale fulvous, below it is white. 

 The last abdominal segment in the centre, is widely and deeply depressed, and is 

 closely rugosely punctured, there is in its centre, a slight shallow curved border, 

 with a short, blunt tooth on either side, outside it are two longer, more sharply 

 pointed teeth. The last ventral segment is also widely and deeply depressed iia 

 the middle; the apex of the penultimate is raised, almost trilobate in the 

 centre, this part being bordered l)y a stout tooth. 



In Bingham's table this species comes near M. penelrata, Sm. ; in that 

 species the vertex, mesonotum and scutellum are bare of pubescence ; Smith 

 calls the nervures ferruginous, while in the present species they are black; 

 Bingham described the wings as '• light flavo-hyaline", in my species they are 

 hyaline, slightly clouded at the apex ; the latter author calls the pollen-brush 

 " bright fulvous." 



Megachile inept a, sp. no v. 



Black; the pubescence on the front, vertex, mesonotum and base of abdomen 

 pale fulvous; the abdominal segments with narrow bands of bright reddish 

 fulvous pubescence on their apices, the pubescence on the face, clypeus, 

 sides and back of head, pleurae sternum and on the basal 3 ventral segments, 

 white, on the apical ventral segments, the white is distinctly tinged with 

 fulvous ; wings hyaline, the nervures black. Mandibles bluntly bidentate, the 

 part behind the teeth broadly, roundly dilated ; the puncturation strong, the 

 base covered with a dense silvery pile. The pubescence on the legs white, on 

 the underside of the hinder metatarsus fulvous ; the base of the hind meta- 

 tarsus about one-third narrower than the apex of the tibi^. 

 Length, 13 mm. 

 Ilah. — Simla — September. 



Head as wide as the thorax. Face and clypeus strongly punctured, the 

 apex of the face with a smooth line, from the centre of which another smooth 

 line runs half way down the centre of the clypeus, the apex of which is rough 

 and transverse. Metanotal area coarsely aciculated. First abscissa of radius 

 not quite one-fourth shorter than the second. 



This species is not unlike M. suhfusca, Cam., of which I only know the $ , 

 1 do not consider them to be sexes of one species, e. g. suhfusca has the stigma 

 testaceous, the basal abscissa of the radius is shorter compared with the 2nd, 

 the wings are not clear hyaline, but distinctly infuscated towards the apex, the 

 apical mandibular tooth is much longer compared with the subapical and the 

 puncturation on the basal abdominal segments is not nearly so strong. 

 Megachile punjanhensis, sp. nov. 



Black; the pubescence clear white, the dorsal abdominal segments with 

 narrow apical bands of clear white pubescence, the scopa white, the apica 

 half mixed with red ; wings clear hyaline, the costa and stigma piceous, the 

 nervures black. Mandibles tridentate, the apical blunter, larger, more rounded 

 than the others, which are triangular. Flagellum for the greater part piceous.
