the outer edge of the labrarea and nearly to end of the middle of its fellow, 

 black except for the apical fourth which is dull dark reddish; palpi nearly- 

 typical ; thorax covered with an abundance of pale-ochreous or what could 

 be called whitish hairs, hairs of dorsulum seemingly shorter than hair of 

 mesopleurae; dorsulum dullish, finely reticulated and sparsely punctured, the 

 punctures indistinct and from two to five or more puncture -widths apart, 

 mostly the latter; notauli represented by a shining fine; mesopleurae dullish 

 with pale-ochreous, virtually whitish hairs throughout, finely reticulated and 

 mostly covered with ill-defined shallow pits, that are mostly two or more 

 pit-widths apart; scutel hairy and sculptured much like the dorsulum except 

 that the sculpture is not so dense and the hairs are apparently as long as on 

 the mesopleurae; metanotum hairy and sculptured like the dorsulum except 

 that the sculpture is denser ; tegulae dark brownish, polished ; wing-base partly 

 dark brownish, subcosta blackish, stigma and remaining veins yellowish 

 stramineous, membrane yellowish; legs blackish excepting most of the small 

 joints of the tarsi which are brownish stramineous, legs covered with pale- 

 ochreous, almost whitish hairs ; hind metatarsi at most hardly wider than mid- 

 metatarsi and nearly half as wide as hind tibiae at apex of the latter ; propodeum 

 with its enclosure defined by a fine raised fine, with irregular rugae on 

 basal half, finely reticulated on apical half, rounded off at apex, rest of upper 

 face sculptured somewhat like the mesopleurae but with smaller pits and 

 covered with pale-ochreous hair ; propodeal pleurae finely reticulated, their pits 

 far apart; floccus pale ochreous; abdomen with its tergum shining, finely 

 reticulated and indistinctly punctured, the punctures indistinct and mostly 

 many puncture-widths apart ; first tergite with erect pale-ochreous, virtually 

 whitish hairs; second and third tergites with inconspicuous, sparse, appressed, 

 ochreous hairs, second tergite with its elevated portion down the middle : 

 depressed portion :: 13 : 6; apical margin of second tergite on left side near 

 the middle abnormally slightly emarginate; third and fourth tergites sculp- 

 tured and hairy much like the second tergite; fifth tergite sculptured and 

 hairy much like the preceding tergite ; tergites with an apical, pale, stramine- • 

 ous edge; seventh and eighth sternites as in the figures of these parts; tergum 

 without well-defined hair-bands; hair at apex of abdomen of a golden hue; 

 cardo shiny, finely reticulated, apically depressed; stipes at base near the 

 middle of the cardo beveled; stipes polished, partly dark brownish, apical

Andrena (Andrena) media, new species. 



Type. — Boston Society of Natural History. 



Type locality. — Glen House, Green Grant, New Hampshire, June 14, 1916 

 (C. W. Johnson). 



Has characters in common with A. (A.) hemileuca Viereck and is closely 

 related to A. (A.) durangoensis V. & C. as is evident through a comparison 

 of the heads, hypopygia, lingams and seventh and eighth sternites. 



Male. — Length 8.5 mm.; body black, mostly covered with ochreous hair; 

 head with its facial line : transf acial line : : 50 : 61 ; axial fine : temporal line 

 : : 20 : 29; temples produced, as in the accompanying figure; malar line : 

 joint 3 of antennae : : 3 : 7; elevated portion of malar space down its middle 

 shorter than the depressed portion; head covered with ochreous hairs through- 

 out, and on front indistinctly punctured, dullish, finely reticulated and with 

 fine longitudinal carinae; front along eye-margin nearly sculptureless; ocel- 

 locular line : ocelloccipital line : : 15 : 5; face shining, distinctly punctured, 

 its punctures from adjoining to three puncture-widths apart and in part, 

 nearly hidden by the hairs; clypeus nearly convex except for being flattened 

 down the middle, not elevated above the middle of the apical margin; clypearea 

 virtually wanting, represented by sparser puncturation down the middle 

 of the clypeus, sculpture of the clypeus not hidden by the moustache; labrarea 

 with a broad rounded emargination, polished, its width at base : greatest
