cubital. Mandibles bidentate, the teeth distinct, the 2nd small compared with 

 the 1st, clearly separated ; the part behind them testaceous, covered with golden 

 pubescence, the basal part thickly with silvery. Head large, as wide as the 

 thorax, the occiput rounded inwardly, not transverse. Apex of clypeus trans- 

 verse, depressed. Base of metanotum forming a distinct border. The pubes- 

 cence on the front, face and clypeus is dense. The calcaria are black. Base 

 of hind metatarsus half the width of the apex of tibiae, the pubescence on the 

 lower side of the metatarsus is white. 

 Length 3 mm. $ . 



This little species comes close to M. nicevillii, Cam. ; the latter is a larger 

 species, it has the apical tooth of the mandibles distinctly longer than its 

 width at the base, while in the present it is not much longer than the basal 

 width ; it wants the clearly defined margined border on the top of the meta- 

 notum and the 1st recurrent nervure is received nearer the base. 



Hcgachile cratodonta, sp. nov. 

 Length 6-7 mm. ft. 

 Deesa. January. 



Very similar in size and colouration to M. gathela, described above ; but 

 easily separated from it by the stronger mandibular teeth, there being also, 

 instead of a broad rounded swelling behind the 2 apical teeth, a large, clearly 

 separated tooth, which is distinctly larger than either of the apical ones ; while 

 the abdominal teeth are much larger, clearly defined and black. Of the latter 

 there are 4 distinct ones, the 2 central being longer, broader and much more 

 clearly separated than the outer ; outside the latter there is a smaller, less 

 distinct tooth. There are 2 stout teeth on the fore cox'ae. Base of hind 

 metatarsus not half the width of apex of tibias, the spurs pale. Wing nervines 

 and stigma black. Metanotal area closely aciculated. 



Megachile ccclioxysides, Bing. 

 Col. Nurse has briefly characterized the ft of this species in the Journal, 

 Asiatic Society of Bengal, LXX, 1901, p. 150. It may be useful to describe 

 the anal segment more fully. In the centre are 2 widely separated teeth, the 

 space between them forming a semicircle ; on either side of this are 2 shorter 

 sharp teeth with a slight stumpy one beyond them ; all these teeth have the 

 apices testaceous. Probably the tosth vary in length and thickness. The 

 mandibles are broad, bidentate, the teeth triangular, the apical much larger 

 than the other ; the basal part is broadly, but not much, dilated in the centre ; 

 the puncturation on the basal part is coarse. 



Megacliile subfuscus (Nurse, M.S.), s.p. nov. 

 Black, the hair on the front, top of thorax and base of abdomen pale 

 rufo-fulvous, that on the rest of the head and thorax much paler, the 

 apices of the 2nd to 4th abdominal segments with bands of pale fulvous 

 pubescence, the hair on the apical 2 segments black, the hair on the 

 legs white, except on the underside of the posterior metatarsus, where 

 it is bright rufous. Wings hyaline, the apex slightly, broadly infuscated,
