Notes on the Megachilidce 
181 
and 4 with a tuft of black hairs on the extreme sides. Length 
13 mm. 
Type: Female; Tarboro, N. C., May 28, 1925, on flowers of 
Tephrosia virginiana. Paratype; 1 female, Raleigh, May 22, 
1925, also on Tephrosia. 
This seems to be quite close to M. vidua Sm., especially to- 
the northern form which is definitely fasciate. It is at once sep- 
arated, however, by the black scopa on segments 5 and 6, and the 
otherwise paler scopa, it being more yellowish in vidua. This 
may possibly be the female of M. ingenua Cress. A male of 
ingenua was caught in the same general type of country (sandy) 
at the same time of year and on the same flower, but in widely 
different localities. This seems hardly sufficient data to fix them 
definitely as the same species. Further collecting may possibly 
establish the relationship.
