HYMENOPTERA OF SARAWAK. 165 



minutely and sparsely punctured. Mesosternum and meso- 

 pleurae thickly covered with black hair ; the meta- with longer 

 and white hair. Fore tibiae with the edges spined ; the onter 

 spine longer and sharper than the inner ; the middle adn hind 

 calcaria red, the others black. 



Mesonotum thickly covered with short black hair ; clypeus 

 longer than the face, its apex transverse in the middle, the 

 sides curved, it is sparsely haired ; metatarsus not much 

 narrower than the tibiae which, at the apex on the outer side, 

 projects into a stout spine. 



This species belongs to a group which appears to be well 

 represented in Malaya. It differs from M. bicanaliculaia and 

 Frederici in the mandibles having 3, instead of 2 teeth ; M. 

 albocaudata Friese has 4 mandibular teeth ; the number of teeth 

 in M. miniata Bingham, (J. Bomh. N. H. Soc. 1890-b), from 

 Sumatra, is not stated. 



Megachile Sarawakensis, sp. nov. 



Black, the hair black, on the vertex, mouth and sternum 

 white, on the median segment soot-coloured ; the wings yellow- 

 ish-hyaline, the nervures and stigma luteous. $ .

Front, vertex and face closely punctured ; the clypeus 

 more closely and finely punctured, the rest more widely and not 

 so strongly as the front ; its apex fringed with long pale fulvous
