THE CANADIAN ENTOMOLOGIST. 153 



Andrena miranda, Smith, 1879. 

 3 ? .. " Clypeus / \ ; area coarsely clathrate and margined ; abdomen 

 strongly punctured." Canada. Related to A. Forbesii, but not 

 the same. 



A?idrena mcesta, Smith, 1879. 

 " Area scarcely rugubse, not margined; abdomen scarcely punctured 

 (lapponica style); tubercle slightly emarginate or bilobed. Canada. 

 This species appears to differ from any known to me. 



Andrena errans, Smith, 1879. 



"Area not margined, smooth nearly ; abdomen with shallow punc- 

 tures ; tubercle pointed (one ? has the discs of abdominal 

 segments densely clothed with black upright hairs, probably a 

 different species)." Vancouver I. This is not the north-western 

 species which I have regarded as errans; the female with hairy 

 abdomen may be pluvialis. 



A close study shows that there are several species confused with 

 vidua or errans in American collections. These ( $ ) all agree in 

 being about 13 or 14 mm. long ; the thorax densely clothed with 

 upright rather short hair (bright ferruginous in Hallii, pale 

 ochraceous in the rest) ; the abdomen shining black, without hair- 

 bands ; the anal fimbria black ; the wings decidedly brownish. 

 The species of this series now before me are : 



A. Carlini, Ckll.: Tubercle of labrum broad and evenly rounded; 

 clypeus with a median impunctate ridge; hair of face mixed pale 

 and black, of pleura black ; basal area of metathorax roughened, 

 not plicate ; abdomen tessellate and well punctured ; antennal 

 joint 3 rather shorter than in Hallii. Illinois ; Beulah, N. M., 

 May 30 ( W. Porter); Baldwin, Kansas, May (J. C. Bridwell); 

 Ithaca, N. Y., May 17 (Macgillivray). Seven specimens ex- 

 amined. 



A. Hallii, Dunning : Tubercle of labrum broad but truncate ; 

 median line of clypeus impunctate, but minutely tessellate; hair of 

 face and pleura black ; basal area of metathorax obliquely plicatu- 

 late at base ; abdomen tessellate, with numerous small punctures. 

 Pullman, Wash. (C. V. Piper). 



A. cupreotincta, Ckll., n. sp.: Tubercle with sloping sides and 

 truncate apex ; clypeus without a median impunctate ridge, or it is 

 very short and rudimentary ; hair of face, cheeks, occiput and
