Meade-Waldo has kindly compared it with Smith's type o£ 

 conspicuus, and finds it certainly distinct. He finds that the 

 prominent keel-like tubercle on the first dorsal abdominal 

 sejji^ment of" 7ti'nandNS is wholly wanting in coii.yjicuKs, which 

 also has the postscutelhim transversely striate and the venter 

 with a fulvous scopa. The scanty hair on abdominal venter 

 of mirandus is light fulvous on basal half, black on apical. 



Andrena btrberidis (Cockerell). 



According to Mr. Yiereck, this is identical with A. neu- 

 rona, Vier., from Seattle, Wash. A, neurona has never 

 been fully described, but in Yiereck's unpublished table of 

 Andrena it is said to have the process of labrum not emar- 

 giiiate, whereas in berberidis it is very distinctly emarginate. 

 Tlie two are, however, very much ahke, and may represent 

 races of a single s|)('cies. 



On April 27, 1913, at flowers of Odostemon, at Boulder, 

 Colorado, Mrs. M. D. Ellis took what is evidently the male 

 of A. berberidis. On the same day, at the same flowers, she 

 also took the female. The male berberidis looks at first sight 

 like A. leptanthi, Y. & C, which is the male of A. porterce, 

 Ckll. It differs from leptonthi in the much shorter clypeus; 

 shorter malar space ; black hair behind upper end of eyes ; 

 angulation of the very broad cheeks lower (about level with 

 middle of eye) ; anterior part of mesothorax (except median 

 smooth line) dull and granular, net punctured; second s.ra. 

 much narrower ; apical plate of abdomen smaller. They 

 are certainly very closely allied. 



Andrena ellinia, sp. n. 



? . — Length about 1.2 mm. 



llather slender, black (tibire, tarsi, and antennseall dark) ; 

 hair of head and thorax rather short; and stifl", very pale, with 

 a greyisli-ochrcous tint ; legs with mostly whitish hair, but 

 light seal-brown on inner side of tarsi, the tuft on hind 

 knees pale reddish ; abdomen without conspicuous liair, 

 except the bands and caudal fimbria ; the bauds on bands 

 2 to 4- broad and white, very narrowly interrupted on 2, but 

 scarcely attenuated toward the interruption ; band on fifth 

 segment pale golden, fimbria light golden-ferruginous. 

 Head broader than long, eyes slightly diverging above ; 

 process of labrum broad, rather narrowly truncate (not 

 emarginate) apically ; malar space linear ; checks rounded, 

 normal ; clypeus prominent, microscopically tessellate, 

 shining in middle, with rather close large punctures, and a
