BEES OF THE FAMILY ANDRENIDAE— TIMBERLAKE 409 



minutely granular-tessellate and dull. Clypeus and mesoscutum 

 with close, fine, shallow, indistinct punctures. Frons finely striate. 

 Basal area narrowly triangular, with a smoother tessellate sculp- 

 ture than remainder of dorsal surface of propodeum. Abdomen 

 tessellate, shining, with minute setigerous punctures. Basal ner- 

 vure usually opposite the transverse median. Second submarginal 

 cell about one-half, or sometimes more than one-half, as long as 

 the third, a little narrowed above, and receiving recurrent ner- 

 vure at or near the middle. Pubescence whitish or cinereous, mod- 

 erately dense, and rather short, being longest on the mesopleura. 

 Hair of mesoscutum in part very short, with longer hairs inter- 

 spersed. Floccus of propodeum about as long as hair of meso- 

 pleuron, but little curled, the pleuron beneath the floccus with 

 a few scattered hairs, except at posterior end. Abdomen with 

 short, erect pale hair on disk of segments, becoming much longer 

 on first tergite and at sides of the second. Tergites 2 to 4 each 

 with a whitish, entire, moderately broad, and dense apical hair 

 band. Apical fimbria brown. Hair of legs whitish, that at apex 

 of hind femora above, and at base of hind tibiae on outer side, 

 brown. Scopa of hind tibiae moderately loose, the hairs on lower 

 margin strongly curled upward and weakly plumose, the hairs 

 on dorsal margin about as long as greatest width of tibia and 

 distinctly plumose. Flocculus of hind trochanters short, scanty, 

 but curled. Length 7.5-8.5 mm. ; anterior wing 6.5-7 mm. 



Male. — Similar to female in color and sculpture. Antennae much 

 longer than in female, the joints of flagellum beyond the second 

 nearly twice as long as thick. First and second joints of flagellum 

 subequal and a little shorter than the third. Mandibles short, 

 not decussate. Process of labrum foveately emarginate at apex. 

 Pubescence of head and thorax long and loose, becoming mod- 

 erately dense on face below antennae and about as long on 

 mesoscutum as on the pleura. A little black hair usually present 

 on sides of face and behind summit of eyes. Pubescence of legs 

 and at apex of abdomen entirely light. Hair of abdomen other- 

 wise as in the female, except that the apical bands are weak. 

 Hair of venter thin and erect, the segments without apical 

 fringes. Length 6-9 mm. ; anterior wing 5.2-6.5 mm.
