364 Mr. T. D. A. Cockerell — Descriptions and 



Bomhus rubriveniris, Lepeletier. 



At Oxforcl, in material belonging to the Hope collection, 

 which had passed through tlie hands of Lepeletier, I found a 

 B. ruhriventris, 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 fiftli 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 brasiliensis) ; hind tibias dark 

 red, with black hair. 



Euglossa analls, West wood. 



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 synon^'^m of E. eordata (L.), 

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



Megachile bicolor (Fabricius). 



In 1919 I published Megachile fletcheri from India, 

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

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

 with bicolor, and sent for comparison both sexes from Coim- 

 batore {Fletcher), Pusa, Behar {G. D. 0.), and Chapra, 

 Bengal [Mackenzie). I took tiiese to the British Museum, 

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

 conclude that all were one species — M. bicolor. 



Megachile seniipleta, sp. n. 



cJ . — Length about 10 mm. 



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

 ferruginous ; antennae entirely black ; head ordinary, face 

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

 chocolate-brown hair ; mesothorax glistening, closely punc- 

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