at apex of the latter; propodeum with its enclosure poorly defined, with irreg- 
ular, fine rugae along the basal edge, elsewhere finely reticulated, rounded off 
at apex, rest of upper face sculptured somewhat like the mesopleura and 
covered with whitish hair, propodeal pleura sculptured like the mesopleura, 
the sculpture not hidden by the whitish hairs; abdomen with its tergum shiny 
almost polished, finely reticulated and indistinctly punctured, the punctures 
mostly three or four puncture widths apart, first tergite, with erect whitish 
hairs, second and third tergites with dark, appressed hairs, second tergite with 
its elevated portion down the middle : depressed portion 15: 5, third, fourth 
and fifth tergites with brownish appressed hairs on the elevated portion, fifth 
tergite with its basal blackish portion covered with poorly defined punctures 
that are as many as four puncture wddths apart, rest of fifth tergite and exposed 
portion of sixth and seventh tergites with a stramineous margin, anal process 
expanding tow'ard apex and deeply emarginate at apex, tergum wdth rather in- 
conspicuous hairs that are supplemented on the second, third, fourth and fifth 
tergites by white, apical hair bands that are more or less interrupted in the 
middle, hair at apex of abdomen of a golden hue. 
Andrena (Andrena) nasoni fulvodorsata new' variety 
Type. — No. 4059, The Academy of Natural Sciences of Phila- 
delphia. Type locality. — Fedor, Lee Co., Texas, March 22,

Female. — Differs from typical A. (A.) nasoni Robertson in the hair of the 
dorsum of the thorax being fulvous. 
Andrena (Andrena) omninigra® new' species 
Type. — No. 4046, The Academy of Natural Sciences of Phila- 
delphia. Type locality. — California. (E. Norton.) 
Related to A. (A.) stictigastra Viereck. 
Female. — Length 15 mm.; body black, covered throughout w'ith black or 
blackish browm hairs; head with its facial line : transfacial line :: 79: 93, axial 
line : temporal line :: 40: 25, malar line : joint 3 of antennae :: 2: 11, oceUocci- 
pital line : greatest diameter of lateral ocellus :: 7: 6.5, elevated portion of malar 
space represented by a shiny line, front distinctly, longitudinally striate, not 
elevated into a w'elt along the fovea, fovea at most : ocellocular line :: 14: 18, 
foveal band represented by a shiny line, distance between fovea and ocelli : 
ocellocular line :: 4: 18, fovea attenuated below' its middle w'here it is apparently 
nearly as w'ide as the greatest w'idth of the fovea, the latter continued to a point 
apparently on the clypeal line, fovea filled w'ith blackish brow'n hairs, face 
mostly polished, not reticulate, w'ith distinct punctures that are as many as 
three puncture w'idths apart near the eye margin, where the punctures are 
larger than near the clypeus where they are adjoining or nearly adjoining, 
clypeus distiiactly elevated above the apical margin, slightly convex, its punc- 
tures larger than the largest of the face, well defined and from adjoining to tw'O
