Megachile dimidiaia, Smith. 



MegachUe dimidiaia, Sm. Oatal. Hymen. Brit. Mus. i. p. 174. no, 88

M. dimidiata (type in British Museum) has the pollen- 

 brush deep fulvous in the centre and black laterally, not 

 entirely black as Smith states; in his description of M. velutina 

 he describes it correctly. 



Bingham (Fauna Brit. India, i. p. 472) separates the two 

 species on the colour of the antennae and legs, which he says 

 are fulvous red in M. dimidiata and black in M. velutina, 

 altliough the original descriptions of both species distinctly 

 state that the legs are fulvous, and specimens determined by 

 Bingham himself as M. velutina have red antennje and 

 fulvous legs. The type of M. velutina was in the collection 

 of the late J. S. Baly. 



Megachile rotundiceps, Smith, ? . 



This species, described from ]\lt. Ophir (type in the Hope 

 Department), belongs to the subgenus Eumegachile. The 

 scopa is silver-white except sternite 5 (at the apex) and 6, 

 where it is black. 



Megachile terminalis, Smith, ? . 



As Friese rightly says, this species is like M. ornata, 

 Smith, but differs in having the scopa black. Other 

 diflerenccs, noticeable on comparing the types of the two 

 species, are to be found in the considerably darker wiugs of 

 M. terminalis and its slenderer form. 



AJegachile placida, Smith, ^. 



Described from Gilolo. The species has a slender, forward- 

 curving spine on each of the anterior coxse. Type in Hope 

 Department. 



Megachile lahoriosa. Smith, S • 

 This species has a short tubercle on each anterior coxa. 

 Type in Hope Department.
