BY T. D. A. COCK.ERELL, N. M. AGR. EXP. STA. 



The following notes are based on specimens collected by Mr. S. N. 

 Dunning, all at Hartford : — 

 (i) Andrena Du/mingi, n. sp. — $. Length 12 mm.; black, with 



ochraceous pubescence. Facial quadrangle broader than long ; 



lateral facial depressions covered with appressed pubescence ; 



clypeus shining, with large close punctures, median line im- 



punctate ; front below ocelli irregularly striate, a keel descending 



from middle ocellus ; vertex minutely roughened, with ill-formed 

 punctures ; antennas reaching to teguJa;, wholly dark, first joint of 

 tlagellum a little longer than the two following together ; mandibles 

 dark, rufescent at extreme tip ; process of labriim broad and low, 

 but very large, gently curved ; thorax, even the metathorax at 

 base, quite densely covered with long fulvo-ochraceous hair, that 

 on pleura like that above ; mesothorax minutely tessellate or 

 lineolate, with strong deep punctures : enclosure of metathorax 

 granular, ill-defined ; teguUt shining, dark brown ; wings strongly 

 flavescent, not darkened at apex, stigtria ferruginous, nervures dark 

 brown ; second submargifial cell very broad, nearly as large as the 

 third, receiving the first recurrent only just beyond the middle ; 

 legs black, the small joints of the tarsi dark reddish-brown ; 

 pubescence of femora, and of hind iibice, ochraceous ; that of the 

 other tibice, and all the tarsi, very dark chocolate brown, shining 

 paler in certain lights ; abdomen shiny, minutely tessellate, luith 

 quite 7iumerous but very small and weak punctures ; surface of 

 abdomen bare, without bands ; apex densely clothed with fulvous 

 hair ; venter with long fulvous hairs. 

 Hab. — Hartford, Connecticut. May 26, 1895 (S- N. Dunning). 

 Superficially this species looks much like A. vicina, but the 

 pubescence of the apex of the abdomen at once separates it. It 

 is very much like A. pruni, but that has the punctures of the 

 abdomen much stronger, the basal joint of the hind tarsi is longer 

 and narrower, and the colour of the tarsal pubescence is entirely 

 different.
