HYMENOPTERA OF THE BOMBAY PRESIDENCY. 655 



all the coxa? and the base of fore femora black ; flagellum of antennas rufous, 

 darker above. Wings clear hyaline, costa and nervures black, the stigma dark 

 testaceous, tegulse rufo-testaceous. 9 



Lensth 6 mm. 



Deesa. December. 



Head distinctly broader than the thorax. Mandibles bidentate, the apical 

 long, gradually narrowed to a sharp point, the subapical broad at the base 

 gradually narrowed to a point at the apex, short, broader at the base than it is 

 long ; from it there is a broad shallow curve to the base; the teeth appear broad- 

 er than usual and are covered with white pubescence at the base. Head closely 

 punctured ; the clypeus with a smooth line in the centre broadest above. Thorax 

 closely punctured ; metanotal area aciculated. The apical ventral surface is 

 darker coloured than the rest. Base of hind metatarsus about one-fourth 

 narrower than the apex of tibiae. There are no depressions or furrows on the 

 back of abdomen, which is roundly convex. The 1st recurrent nervure is 

 received shortly beyond the apex of the basal fourth ; the 2nd nearer the apex. 

 Tegute pale testaceous. 



In one example the back of the abdomen is brownish for the greater part ; 

 in another the segments are only brownish under the pile. 



Megachile erythrostoma, sp. nov. 



Black, the apex of clypeus broadly, the .mandibles broadly at the base, and 

 the femora and tibiae more or less in front, rufous ; the greater part of the 

 flagellum piceous, the hair on the thorax, upper part of abdomen and head 

 white, the ventral scopa bright red ; wings clear hyaline, the nervures black. 

 Mandibles large, trideutate, the apical tooth long, bluntly narrowed, the apex 

 somewhat broadly rounded : the 2nd large, clearly separated from the apical, 

 the apex roundly narrowed, longer than it is wide at the base ; the 3rd is shorter, 

 broader, not so oblique and turned inwardly. Apex of clypeus broadly rounded. 

 Puncturation of head and thorax fine and close, that on the scutellum stronger 

 than on the mesonotum ; that on the abdomen is still finer. The abdomen 

 becomes gradually narrowed towards the apex, which forms a bluntly-rounded 

 point ; the latter is rufous at the apex ; there are no distinct transverse furrows 

 or depressions on the dorsal surface. $ . 



Length 11 mm. 



Deesa. 



The mandibles are longer than usual and more particularly the apical tooth, 

 especially as regards the length compared with the width at the base. The 

 abdomen, too, becomes more distincly narrowed from the base to the apex. 

 Base of hind tarsi half the width of tibia). 



Megachile suavida, sp. nov. 



Black, the mandibles, except the teeth, pale yellow ; flagellum for the greater 

 pait reddish, the hind femora and tibiae except above and the tarsi rufous ; 

 the hair on the head and thorax long and dense ; all the abdominal segments
