BEES OF THE FAMILY ANDRENIDAE— TIMBERLAKE 389 



Female. — Black, the mandibles strongly reddened except on 

 the basal third. Flagellum brownish beneath. Small joints of tarsi 

 ferruginous, the basitarsi more dusky. Tegulae reddened at apex. 

 Wings as in limnanthis as to color and neuration, except that the 

 second submarginal cell is less narrowed above. Apical margin 

 of tergites, especially of the second, subhyaline and then red- 

 dened. Head and thorax very finely tessellate, dullish, although 

 a little shining in some aspects. Clypeus subopaque, impunctate. 

 Frons finely striate. Mesoscutum with fine, close, but indistinct 

 punctures. Enclosure of propodeum and abdomen nearly as in 

 limnanthis. Process of labrum small, very short, a little emar- 

 ginato-truncate on middle of apex. Facial foveae whitish, broad 

 above, each covering slightly more than one-fourth of space be- 

 tween the eyes. Antennai joint 3 about equaling the next three 

 joints together. Pubescence whitish to pale ochreous, most con- 

 spicuous on the face and cheeks, the hair of clypeus subdepressed 

 and partially concealing the surface. Hair of mesonotum short 

 and erect, becoming longer on anterior part of scutum and on 

 apical margin of scutellum. Pubescence of abdomen fine and ap- 

 pressed, forming white apical hair bands on tergites 2 to 4, 

 these bands being broadly interrupted on tergites 2 and 3. Apical 

 fimbria tinged with brown. Hair of legs mostly whitish, but 

 brownish on outer side of middle tibiae at apex, with tuft at apex 

 of hind femora, and the tips of scopal hairs on dorsal side of 

 hind tibiae, brown. Scopa of hind tibiae rather long and moder- 

 ately dense, the hairs on dorsal margin obviously plumose and 

 slightly longer than greatest width of tibia, the hairs on the outer 

 surface obscurely plumose. Labial palpi short, the basal joint 

 strongly bowed; the two middle joints short, thickened, and 

 oblique, hardly longer than wide; the apical joint slender and 

 nearly twice as long as preceding joint. Length 7-9 mm.; an- 

 terior wing 6-6.6 mm. 



Male. — Similar to female. Clypeus, except outer corners and 

 narrow apical margin, pale yellow. Tergites narrowly reddened 

 contiguously to the subhyaline apical margins, these reddened 

 areas on tergites 2 and 3 definitely much widened on each side to 

 form more or less conspicuous spots. Process of labrum small, 

 more thickened and more prominent than in female, rounded and 

 arched apically, and, at most, weakly foveate medially below the 

 margin. Antennae short, with joint 3 equaling 4 plus 5, which 

 are quadrate. Pubescence white, much longer than in female, with 

 the hair of face and cheeks rather dense and almost concealing 

 the yellow clypeal mark. Hair of mesonotum long and thin, that 

 of first tergite similar, and that of following segments short and 

 appressed, forming weak apical hair bands on tergites 3 to 5.
