face of propodeum sculptured somewhat like the mesopleurae and 

 covered with whitish hair, propodeal pleurae with delicate reticula- 

 tions, more shiny than the mesopleurae and more sparsely punctured 

 and almost hidden by the whitish floccus; abdomen black with a 

 bluish tinge, with its tergum shining, finely reticulated and punc- 

 tured, first tergite more distinctly and more closely punctured than 

 the face, punctures on the elevated portion of the second and third 

 tergites nearly as close together as on the disc of the first tergite and 

 a little larger than on the depressed portions, second tergite with its 

 elevated portion down the middle : depressed portion :: 18 : ll r 

 fifth tergite dullish and with rather indistinctly defined punctures 

 that are from three to four puncture widths apart, pygidium black, 

 planatc, pointed at apex, dullish without an enclosure, tergum with 

 inconspicuous pale hairs, second, third and fourth tergites without a 

 hair band, fimbria pale seal-brown. 



Other Locality. — Half way up Mt. Hamilton Road near San Jose, 

 California, on wild cherry (H. Morrison, 1,477). 



Andrena (Andrena) stictigastra new species.

Female. — Length 9.5 mm.; body black, covered throughout with 

 black or blackish brown hairs; head with its facial line : transfacial 

 line :: 57 : 80, axial line : temporal line :: 30 : 17, malar line : joint 

 3 of antennae :: 2 : 7.5, elevated portion of malar space barely 

 represented, head covered with black or blackish brown hairs, front 

 coarsely striated, fovea at most : ocellocular line :: 10 : 16, foveal 

 band poorly developed, fovea virtually contiguous to the upper end of 

 the inner eye margin, distance between fovea and ocelli : ocellocular 

 line :: 5 : 16, fovea constricted near its middle where it is apparently 

 half as wide as the greatest width of the fovea, the latter continued below 

 the constriction as a shallow depression down to a point apparently on 

 the clypeal line, fovea with dark hair, fovarea wanting, face polished, 

 not so densely punctured as the clypeus, clypeus slightly elevated 

 above the apical margin, convex, shining, covered with distinct 

 adjoining or nearly adjoining punctures, clypearea exceedingly 

 narrow but extending nearly from base to apex, clypeus thinly hairy 

 with dark hairs, labrarea rounded truncate, its width at base : length 

 down the middle :: 10 : 5, width at apex : length down the mid- 

 dle :: 3 : 5, labrarea at base nearly half as wide as the labrum, the
