hairy like the mesopleurae, its sculpture denser and less distinct than that of 

 the dorsulum; tegulae brownish stramineous, almost polished, wing-base 

 partly blackish brown; subcosta blackish brown, stigma and other veins 

 pale brownish stramineous, membrane uniformly yellowish; legs blackish 

 except for the small joints of the tarsi which are more or less stramineous, 

 legs covered with brownish-golden and ochreous hairs; scopa typical, its hairs 

 pale yellowish golden except at base above where they are brownish, hairs at 

 base above decidedly darkened; hind metatarsi at most apparently a little 

 narrower than mid-metatarsi; propodeum with its enclosure poorly defined, 

 dullish and finely reticulated, its basal half with rather distinct rugae; rest 

 of upper face of propodeum sculptured somewhat like the mesopleurae and 

 covered with finer pale-ochreous hair; propodeal pleurae finely reticulated 

 and with sparse shallow punctures; abdomen with its tergum shining, finely 

 reticulated and sparsely, indistinctly punctured, the punctures from two to 

 six or more puncture-widths apart on the first tergite, the punctures hardly 

 closer on the succeeding tergites; second, third and fourth tergites subfasciate 

 laterally, apical edge of first, second, third and fourth tergites with a stramin- 

 eous border; second tergite with its elevated portion down the middle : 

 depressed portion :: 17 : 6; fifth tergite shining, reticulate, its punctures more 

 distinct than on the other tergites; pygidium convex at the end where it is 

 nearly pointed; tergum with inconspicuous pale hairs; fimbria brownish 

 golden. 



Andrena (Andrena) lata, new species. 



Type. — Boston Society of Natural History. 



Type locality. — Bar Harbor, Maine, June 8 (C. W. Johnson). 



Has characters in common with A. (A.) xanthostigma Viereck. Named 

 lata on account of the broad foveae. In the sculpture of the clypeus, shape 

 of the labrarea, sculpture of propodeum and abdomen there is so much 

 resemblance between this species and A. vulgaris Viereck that I would not 

 be surprised if they should prove to be sexes of the same species. 



Female. — Length 9 mm. ; body black, mostly covered with pale-ochreous, 

 almost white hairs; head with its facial line : transfacial fine : : 55 : 67; axial 

 line : temporal fine :: 27 : 18; malar line : joint 3 of antennae :: 2 : 9; ele- 

 vated portion of malar space virtually wanting; ocelloccipital line : greatest 

 diameter of lateral ocellus :: 4 : 4; head covered with pale-ochreous hairs, 

 front rather indistinctly longitudinally sculptured, not elevated into a welt 

 along the fovea; fovea at most : ocehocular fine :: 10 : 14; distance between 

 fovea and ocelli : ocehocular fine :: 4 : 14; foveal band wanting at upper 

 end of the inner eye-margin, fovea typical, attenuated below its middle, and 

 continued to a point apparently on the clypeal fine; fovea filled with pale- 

 ochreous hairs; hairs of vertex and temples along the upper edge of the eye 

 ochreous; face mostly finely reticulate, with rather indistinct punctures that 

 are as many as three or more puncture-widths apart; clypeus slightly elevated 

 above the apical margin, convex, sculptured like the face except that the 

 punctures are larger, better defined and closer together; clypearea wanting; 

 clypeus thinly hairy, its sculpture not at all hidden by hairs; labrarea sub- 

 emarginate, its width at base : length down the middle : : 12 : 3 ; width at apex 

 : greatest length :: 6 : 4; labrarea at base : distance between lower corners 

 of clypeus :: 12 : 20; labrum with a fringe of brownish-golden hairs, but 

 with barely a suggestion of a median longitudinal crista between the labrarea 

 and apical edge of labrum; joint 3 of antennae : 4+5 :: 9 : 8; joints 4 and 5 

 thicker than long, the succeeding joints as thick as long or longer than thick 

 except joint 12 which is nearly twice as long as thick; antennae blackish 

 throughout; mandibles atypical, robust, extending to the outer edge of the 

 labrarea, black except for the apical fourth and inner edge which are clear 

 dark reddish; palpi nearly typical; thorax covered with an abundance of 

 pale-ochreous, almost white hairs which are shorter on the dorsulum where 

 they are darker than the almost whitish hairs on the mesopleurae; anterior
