Female. — Length 10 mm.; essentially as in A. (A.) Candida Smith 

 from which it differs chiefly in the fovea? reaching at most to the 

 antennal line instead of to the clypeal line as in typical Candida. 

 In this race there is no black hair whatever on the temples. Clypeus 

 down the middle mostly reticulate on the basal half and mostly 

 transversely striate on the apical half. 



In a paratopotype the clypeus is almost polished on its apical half. 



Andrena (Andrena) complicata 2 new species. 



Type. — No. 4,042. The Academy of Natural Sciences of Phila- 

 delphia. 



Type Locality. — San Jose, California. (Hold.) 



Related to A. (A.) trizonata (Ashmead) and A. (A.) Candida Smith, 

 and may prove to be a race of the latter. 



Female. — Length 8 mm.; body bluish, mostly covered with pale 

 ochreous almost white hairs; head with its facial line : transfacial 

 line :: 56 : 67, axial line : temporal line :: 27 : 16, malar line : joint 

 3 of antennae :: 2 : 9, ocelloccipital line : greatest diameter of 

 lateral ocellus : : 4 : 4, elevated portion of malar space nearly wanting, 

 head covered with whitish and black hairs, the latter present along 

 the inner eye margin, on most of the front, vertex and upper end of 

 temples, and along the upper two-thirds of the outer eye margin, 

 front rather distinctly, longitudinally striate, not elevated into a 

 welt along the fovea, fovea at most : ocellocular line :: 6 : 13, foveal 

 band wanting, distance between fovea and ocelli : ocellocular 

 line :: 7 : 13, fovea nearly parallel sided, not attenuated below its 

 middle but continued to a point apparently a little below the antennal 

 line, fovea filled with dark seal brown hairs above the middle, with 

 pale hairs below the middle, face mostly nearly polished, indistinctly 

 reticulate, with indistinctly denned punctures that are mostly as 

 many as two puncture widths apart, face with a lateral, coppery 

 margin, clypeus slightly elevated above the apical margin, coppery 

 and blackish with a basal bluish margin, convex, sculptured like 

 the face except that the punctures are larger and well defined and 

 not so close together, clypearea wanting, clypeus with, its basal half 

 shining reticulate, its apical half nearly polished, clypeus thinly 

 hairy its sculpture not at all hidden by hairs, labrarea rounded, its 

 width at base : length down the middle :: 10 : 3, labrarea at base a 

 little more than half as wide as the labrum, the latter with a fringe 

 of pale brown hairs, labrum apparently sculptureless and structure- 



2 This specific name was proposed for this species years ago by Prof. W. M. 

 Davis.
