NEW NORTH AMERICAN BEES 
ajiparontly closer together than on the other tergites, pygidinm slightly convex, 
apparently without a shallow furrow on each side, nearly pointed at apex, black, 
terguin with inconspicuous pale nearly erect hairs in addition to the hair bands, 
fimbria dull pale brownish or whitish wdth a brownish tinge. 
Andrena ( Gonandrena ) persimulata^ new subgenus, new species 
Type. — No. 4069, The Academy of Natural Sciences of Phila- 
delphia. Type locality. — Milwaukee, ^\'isconsin. June 5, No. 
15. (S. Graenicher.) 
Ignoring the mesopleura, this species is related to A. (P.) 
palUdiJovea Viereck. Superficially it is like A. (A.) barharica 
Mereck. 
Female. — Length 9 mm.; body black, mostly covered with pale ochreou.s or 
whitish hairs; head with its facial line ; transfacial line 50: 61, axial line: tem- 
poral line :: 26: 16, malar line : joint 3 of antennae :: 1.5: 8, ocelloccipital line : 
greatest diameter of lateral ocellus :: 4: 4, elevated portion of malar space vir- 
tually wanting, head covered with w'hitish hairs, front rather indistinctly, 
longitudinally striate, not elevated into a welt along the fovea, fovea at most 
: ocellocular line : : 5 : 10, foveal band present and near upper end of the inner 
eye margin : ocellocidar line :: 1.5: 10, distance between fovea and ocelli : 
ocellocular line :: 4.5: 10, fovea slightly attenuated below its middle and con- 
tinued to a place apparently on the clypeal line, fovea filled with pale ochreous 
hairs, fovarea wanting, face partly polished, mostly indistinctly reticulate, with 
distinct ])unctures that are as many as five or more puncture widths apart, 
through mostly one to three puncture widths apart, clypeus not elevated above 
the apical margin, which latter is somewhat turned up, clypeus convex, finely 
reticulafed and distinctly punctured, the punctures mostly from two to four 
puncture widths apart, clypearea wanting, clypeus thinly hairy, its sculpture 
not at all hidden by hairs, labrarea nearly quadrate, but rounded off at apex, 
its width at base : length dovm the middle :: 7: 5, width at apex : length down 
the middle :: 5: 5, distance between lower angles of clypeus : width of labrum 
at base :: 16: 7, labrum wdth a fringe of golden hairs and without a median 
longitudinal crista betw'een the labrarea and the apical edge of the labrum, 
joint 3 of antennae : 4-|-5 :: 8: 7, joints 4 and 5 much thicker than long, the 
succeeding joints from a little thicker than long to a little longer than thick 
except joint 12 wdiich is nearly twice as long as thick, antennae blackish above, 
blackish browm beneath, mandibles typical, robust, extending almost to the 
low'er corners of the clypeus, black except for the apical half which is mostly 
dark reddish, palpi nearly typical; thorax covered with an abundance of pale 
hairs wiiich are shorter on the dorsulum where they are ochreous than the 
W'hitish hairs on the mesopleura, dorsulum dullish, reticulated and punctured 
like the clypeus but more distinctly so, notauli represented by a shiny line, 
mesopleura almost conically jiroduced at the anterior inferior corner, finely 
reticulate and indistinctly punctured, scutel hairy and punctured much like 
^ This species w'as doubtfully referred to A. simulata Provancher by Dr. 
Graenicher.
