BEES OF THE FAMILY ANDRENIDAE— TIMBERLAKE 377 



distinctly wider than long, with inner orbits of eyes slightly con- 

 verging below. Facial foveae covering about three-fourths of 

 space between eye and lateral ocellus, somewhat narrowed below, 

 where they reach a little below level of antennae. Basal process 

 of labrum with strongly diverging sides, the truncate or trun- 

 cato-emarginate apex about two-fifths as wide as the base. Mandi- 

 bles not emarginate within, the explanate margin on outer side 

 near base very narrow. Third antennal joint barely longer than 

 the next two together. Middle basitarsi dilated and considerably 

 wider than the hind pair. Basal nervure before the nervulus. 

 Stigma narrow. Second submarginal cell quadrate, less than half 

 as long as third, and receiving the recurrent nervure a little be- 

 yond the middle. Head and thorax very finely granular-tessellate, 

 the frons minutely indistinctly striate. Face below antennae with 

 fine, close, indistinct punctures, but those on middle of clypeus 

 much coarser and somewhat separated. Clypeus with a median 

 ridge. Mesoscutum closely and indistinctly punctured. Basal area 

 of propodeum small, minutely tessellate, and slightly roughened 

 at base. Abdomen a little more shining than thorax, finely and 

 very obscurely punctate. Length 9-10 mm.; anterior wing 6-6.4 



mm. 



Male.— Much like the female except in the creamy-white or 

 pale-yellow face marks, which cover the clypeus and broad space 

 between clypeus and eye. Anterior margin of clypeus and two dots 

 on disk, black. Flagellum broadly ferruginous beneath except at 

 base. Inner orbits distinctly convergent below. Cheeks moderately 

 wide and strongly receding behind. Mandibles short, slightly 

 curved, and dentate within near apex. Third antennal joint some- 

 what shorter than the next two together. Flagellum rather stout, 

 with the middle joints nearly II/2 times longer than thick. Sculp- 

 ture similar to that of female, but clypeus without a median ridge, 

 a little shiny on anterior middle, and the punctures of face small, 

 a little separated on middle of clypeus, and elsewhere indistinct. 

 Pubescence a little thinner than in female, and not much short- 

 ened on mesonotum. Hair of abdomen about the same, except that 

 the apical fasciae are very narrow. Venter with short, erect hair 

 and a distinct fringe on the apex of segments 2 to 5. Hair at 

 apex of abdomen a little brownish. Hair of legs rather short and 

 whitish, that on inner side of tarsi pale ochreous. Sixth ventrite 

 with a broad, rounded emargination at apex, the margin not re- 

 flexed. Latero-apical lobes (or parameres) of stipites with a broad 

 triangular dilation on a little less than the apical half. Medic- 

 apical lobes of stipites well developed and a little divergent. Sagit- 

 tae short, moderately dilated and subangulate subbasally on each 

 side, then gradually narrowed to a broad, blunt point and strongly
