Bomhus ruhrivenii-is, Lepeletier. 



At Oxforcl, in material belonging to the Hope collection, 

 which had passed througii the hands of Lepeletier^ I found a 

 B. rubriventris, probably the type. It is labelled " St. Do- 

 mingue.'' It is a remarkable Bomhus, black, with abdomen 

 beyond first segment covered with very bright blood-red hair 

 as far as end of fourth segment (red hair overlapping fifth), 

 but black on fifth segment. Malar space moderate (rather 

 shorter than in hrasiliensis) ; ocelli small; top of head and 

 mesothorax in front with black hair, but behind the broad 

 band on front of mesothorax, abruptly, the short hair is dull 

 grey ; long grey hairs at sides of scutellum ; pleura with pale 

 greyish hair ; anterior wing about 18 mm., dark reddish 

 fuliginous (not so dark as in Z'rasi/ten.'jis) ; hind tibiae dark 

 red, with black hair. 



Euglossa analis, Westwood. 



I found a specimen, evidently the type, at Oxford. Clypeus 

 with the usual three keels; labrum &c. creamy white ; dark 

 purple-blue, apex of abdomen (beyond fourth segment) 

 broadly and abruptly emerald-green. 



Length 10 mm. or a little over. 



Friese gives this as a doubtful synonym of E. cordata (L.), 

 but it is evidently the prior name for E. azurea^ Ducke. 



Megachile hicolor (Fabricius). 



In 1919 I published Megachile fletcheri from India, 

 believing it to be closely allied to but separable from hicolor. 

 Mr. T. B. Fletcher wrote that he considered it to be identical 

 with hicolor^ and sent for comparison both sexes from Coim- 

 batore (Fletcher), Pusa, Behar (6r. D. 0.), and Chapra, 

 Bengal {Mackenzie). I took these to the British Museum, 

 and, on comparing them with the series there, could only 

 conclude that all were one species — M. hicolor. 



Megachile semipleta, sp. n. 



^ . — Length about 10 mm. 



Black, with small joints of tarsi reddened, the last bright 

 ferruginous ; antennae entirely black ; bead ordinary, face 

 and cheeks with long creamy-white liair, vertex with dark 

 chocolate-brown hair ; mesothorax glistening, closely punc- 

 tured, with brownish-black hair, but other parts of thorax
