to meet the transversomedial, the latter being oblique, with 

 its lower end more apical ; stigma large ; marginal cell ending 

 very obtusely, not in a point on costa, but not truncate ; vena- 

 tion of hind wings perfectly normal for the Andrena series; 

 transversomedial nervure moderately oblique. 



Pelandrena reducta sp. nov. 



9 . Robust, of ordinary form ; length about 7 mm., anterior wing 

 about 4 mm. ; head and thorax black or nearly ; abdomen and legs 

 reddish brown; wings hyaline, becoming dusky on apical half; nervures 

 and stigma rather light reddish brown ; antennae ordinary, flagellum 170 

 u. thick ; hind legs with a copious and dense scopa. The following 

 measurements of the anterior wing are in micromillimeters. 



Depth of stigma 221 ; length of basal nervure on first discoidal (not 

 allowing for curve) 595; length of marginal cell IIQO, its breadth 

 (depth) 340; length of first submarginal (from lower basal to upper 

 apical corners) 714; second submarginal on marginal 357, on first discoi- 

 dal 153, on third discoidal (not allowing for gentle outward curve) 442, 

 and its outer side 187 ; first discoidal on third 442. Second recurrent 

 nervure strongly bowed outward, but without any double curve. 



Hab. Miocene shales of Florissant, Colorado, Station 4 (IV. 

 P. Cocker ell.'} In my table of Florissant bees (Bull.-Mus. 

 Comp. Zool., 1906) this runs to Libellulapis, but differs en- 

 tirely in the shape of the second submarginal cell. 



Halictus miocenicus sp. nov. 



$ . Length 7 mm. ; anterior wing about 4 l / 2 ', width of abdomen about 

 2 3-5 mm. ; head and thorax black ; abdomen and legs ferruginous ; 

 wings hyaline, slightly reddish, nervures and stigma pale ferruginous ; 

 antennae normal, the flagellum about 2 1-5 mm. long. Head with very 

 dense rather large punctures, so as to have a finely cancellate appear- 

 ance; eyes prominent, apparently shallowly but broadly emarginate on 

 inner side ; metathorax finely granular, the sculpture finer than that of 

 head; hind tibia and tarsi; with a very copious scopa. Venation nor- 

 mal for Halictus; second submarginal cell very narrow, receiving the 

 first recurrent nervure near its end ; third transverse-cubital without any 

 double curve, third submarginal cell receiving second recurrent 

 nervure somewhat beyond the beginning of its last third; stigma large; 

 marginal cell ending in a point on costa; lower section of basal nervure 

 very strongly curved. Venation of hind wings perfectly normal for 

 Halictus. 



The following measurements of the anterior wing are in micromilli- 

 meters; depth of stigma, 238; length of marginal cell 1377, its depth
