6 THE CANADIAN ENTOMOLOGIST. 



purplish-black. No hair-bands, but a very fine glittering pile all over, 

 longer pale hairs at base of first segment, sparse black hairs on dorsum of 

 hindmost segments and at tip. Punctuation of second segment con- 

 spicuously closer than that of first. Venter piceous, first three segments 

 with blue reflections. End of third segment with a large dark brown 

 brush of hair, shaped like the tail of a fish ; /. e. deeply emarginate, the 

 sides diverging and ending in a point. 



Hab. — San Rafael, Vera Cruz, March 13, on flowers of plant No. 4, 

 which is papilionaceous (C. H. T. Townsend). 



This beautiful species is named after Lt.-Col. Bingham, without whose 

 notes on the British Museum types I should not have attempted this 

 paper. 



Aui^ocJilora ata-ifera, n. sp. (subg. AngocJilora, s. str.) — V • Length 

 about 7}^ mm , green; head and thorax dullish, rather a bluish-green ; 

 abdomen shining, a yellower green^ with the hind margins of the segments 

 very narrowly coppery. Face fairly broad, emargination of eyes deep. 

 Pubescence of head and thorax sparse and inconspicuous, dirty whitish, 

 some black hairs on thoracic dorsum ; lower part of face in certain lights 

 canescent. Clypeus with close punctures of unequal size, supracypeal 

 area more finely punctured, vertex coarsely granular. Labrum and 

 margin of clypeus black. Mandibles notched within, stout, rufescent 

 medially. Glossa very long and narrow, coming to a fine point. An- 

 tennae black, flagellum slightly rufescent beneath. Mesothorax very 

 closely, finely, and uniformly punctured. Enclosure of metathorax con- 

 spicuously longitudinally, or rather radiately, sulcatulate. Truncation 

 shining, finely malleate, with a median groove. Tegulae shining piceous, 

 the margin subhyaline. Wings smoky, stigma dull testaceous, nervures 

 fuscous, marginal cell appendiculate. Legs piceous-black, with brownish 

 pubescence ; only the anterior femora show any green. Abdomen shin- 

 ing, with minute, not very close, punctures ; pubescence very sparse, no 

 hair-bands. It requires a strong lens to see the abdominal punctures. 



Hab. — San Rafael, Vera Cruz, March g, on flowers of plant No. 6, 

 referred by Dr. Rose to the genus Melopodiiun. The hind legs, base of 

 thorax and abdomen, and ventral surface of abdomen, carry considerable 

 (juantities of the orange pollen. Another specimen differs by being much 

 bluer, the punctuation a little coarser, the stigma fuscous ; but it is evi- 

 dently the same species. It is from San Rafael, March 14, on flowers of 

 plant No. 5, a Vernonia. Both were collected by Prof. C. H. T. Town- 

 send.
