Head and thorax very dark purplish, nearly black, but a blue-green spot at upper end of clypeus, supraclypeal area brilliant purple, and base of metathorax strongly tinged with purple; anterior and middle legs dark, with weak purple tints, but hind femora, tibiæ and basal half of basitarsi all brilliant green on outer side; abdomen short and broad, shining, very brilliant emerald green. ”

“ I give an artificial key, which will enable one who is not a specialist in bees to separate readily each species from the rest. It will, of course, remain necessary to compare any species with a fuller account to make sure that it is not some form unrepresented in the present collection. ”
