ANDRENA KNUTHI Alfken. 



Two males from Wakasa, Japan (T. Fukai). The dark markings 

 on the upper part of the clypeus may be barely visible (excepting the 

 usual spots, which are always distinct), or the whole upper two- 

 fifths of the clypeus may be black. The abdomen is extremely shiny, 

 with the hind margins of the segments testaceous. 



ANDRENA PR^COCIFORMIS, new species. 



Male. — Length 8 to 9 mm., black, with long white hair on head, 

 thorax, and legs, black at sides of face, upper part of cheeks behind, 

 and a little on scutellum. In Schmiedeknecht's table of European 

 species it runs to A. parvula, but it actually resembles A. prsecox 

 Scopoli, so much so that at first sight it seems to be the same. It 

 differs from prsecox by the rather smaller size; the cheeks, though 

 broad, dullish except near the eye, and not angled behind (shiny and 

 angled in prxcox) ; the mandibles moderate, without the very long 

 falciform apical tooth of prsecox; the head above and cheeks with less 

 black hair ; the sides of thorax behind with hair all white ; the meta- 

 thorax rougher; the hind margins of abdominal segments a little 

 reddish, and with a tendency to thin marginal hair bands at sides. 

 Mesothorax dull and rough; metathorax very dull and rough, the 

 area ill defined, minutely granular, roughened basally, its apical angle 

 acute; tegulse very dark ruf o-piceous ; wings as in prsecox, but stigma 

 darker (variable) ; first r. n. joining the broad second s. m. about 

 middle; abdomen shining, without distinct punctures. Antennal 

 joints 3 to 5 measured as follows in two specimens: the type, (3.) 374, 

 (4) 255, (5.) 340 p.. Another, (3.) 323, (4) 306, (5) 340 p.. The 

 latter specimen is the larger. 



Habitat. — Japan, specimens numbered 1G6 and 54. 



The Calif ornian A. knuthiana Cockerell is also allied. A. japonica 

 Alfken is also compared with prsecox, but it is larger and evidently 

 different.

ANDRENA RUPSHUENSIS, new species. 



Female. — Length slightly over 11 mm.; black, with pale hair, the 

 form rather slender, at first sight rather suggesting a male; hair of 

 head and thorax long and loose, white below, very pale ochreous 

 above, vertex and sides of front with dark fuscous hair; face very 

 broad, eyes small, so that the facial quadrangle is about 1§ as broad 

 as long; malar space large, brilliantly shining; mandibles with the 

 apical half obscurely ferruginous; cheeks broad, shining; process of 

 labrum broad, truncate; clypeus brilliantly shining, well punctured, 

 except a broad smooth median band; front dull and roughened; 

 facial fovese broad, occupying much more than half space between
