in front, brownish-ferruginous; anterior femora with a whitish 

 spot just before apex; tegulae very dark reddish-brown; wings long, 

 stigma (which is large), and nervaires piceous; apex of wings 

 strongly dusky; b. n. falling short of t. m. ; abdomen dull, only the 

 extreme margins of the segments glistening; shape of abdomen 

 rather long-oval, wide in middle; apical plate deeply notched; ven- 

 ter, except at base, markeci with white. 



Habitat: Mountains near Claremont, California {Baker; Po- 

 mona coll. 171). A distinct little species, easily known by its 

 color. It falls close to A^ obscureUa Fowler, but that is larger 

 (7.5 mm.), with legs largely yellow, including the middle and hind 

 basitarsi, which are entirely black in melanosoma. 



Nomada subviciualis Cockerell. 

 Two males from Claremont {Baker) differ a little from the type. 

 One has small yellow spots at anterior corners of scutellum, lateral 

 margins of mesothorax very narrowly reddish, lateral face-marks 

 continued as slender lines part way up sides of front, and apical 

 plate of abdomen quite broad. The other lacks the yellow patch 

 on second ventral segment. 



Noviada civilis Cresson. 

 Two males from Claremont {Baker) are peculiar for having the 

 apical plate of abdomen entire. One is about 9 mm. long, and has 

 large yellow spots on the metathorax. The other is about 7 mm. 

 long, and has the metathorax all black. A", civilis is one of the 

 most variable of bees, but it appears difficult to satisfactorily define 

 subspecies. A^. ed-ivardsii Cress, is another yellow and black species 

 found by Baker at Claremont. 



Nomada erythrospila sp. n. 

 $ Length about 7 mm.; long and slender; head and thorax 

 black, with white hair, abundant on face, pleura and sides of meta- 

 thorax; head transversely oval; front, mesothorax and scutellum 

 dull and rugose; mandibles simple, pellucid white at base, fulvous 

 in middle, and dark at apex; labrum creamy-white, covered with 

 white hair; lower margin of clypeus and lower corners of face 

 (with a linear extension upward along orbits) cream-color; an-
