marginal cell very long, receiving first recurrent nervure nearly as 

 far from base as the length of first intercubitus, but the second 

 recurrent practically at apex ; basal nervure meeting nervulus on the 

 basad side, the latter not in line with it, but directed a little apicad, 

 bulging outwardly. The following measurements are in microns: 

 Second submarginal cell on marginal, 960; lower side of first sub- 

 marginal cell, 1184; first recurrent nervure from basal corner of 

 second submarginal, 480; first recurrent to second (on second sub- 

 marginal) 1280.

H olotype.— Cd^t. No. 69601, U.S.N.M. 



A true Megachile^ by reason of the fuliginous wings resembling 

 some of the modern Indian species, and like them, having the base 

 distinctly pallid, though only for a short distance. The distance of 

 the first recurrent nervure from the base of the second submarginal 

 cell is an unusual feature, which I do not observe in living species

PHILAGRA(?) KUDIANA, new species 



Plate 1, fig. 3 



Hind wing 18.5 mm. long, entirely fuliginous; r.-m. cross vein 

 transverse (vertical), 6 mm. from apex of wing; m.-cu. cross vein 

 strongly oblique, arched, its lower end apicad, about 0.6 mm. from 

 fork of cubitus and a little over 7 mm. from end of upper branch 

 of cubitus; cubital fork wide; second anal undulate, with a strong 

 double curve.

HoloUjpe.—C?it. No. 69602, U.S.N.M. 



Phllagra^ a genus now ranging to China, Japan, and Australia, 

 has exactly the same venation, but whether the fossil species had 

 the produced head of Philagra we cannot laiow. AphropJiora 

 differs by having the lower cross vein vertical, as I have verified by 

 examining various species. Oosmoscarta has this cross vein oblique, 

 but the lower end is basad. This fossil may be compared with 

 Aphrophora angusta Handlirsch, from the Tertiary of Tulameen 

 River, British Columbia. This species is quite as large as ours, 

 but has a cu.-a. cross vein, and a much narrower cell between 

 branches of cubitus.
