below at about level of antennae. Flagellum dark red beneath; 

 third antennal joint not as long as next three combined. Meso- 

 thorax moderately shining, with weak punctures. Area of meta- 

 thorax granular. Tegulae rufopiceous. Wings dusky hyaline. Ner- 

 vures and stigma amber color. Basal nervure meeting transverse 

 median. Second submarginal cell receiving first recurrent nervure 

 well beyond middle. Middle and hind tarsi red. Hair of hind tibiae 

 yellowish white. Abdomen dullish, not punctured. Second segment 

 in middle depressed less than one-third. Second and following seg- 

 ments with thick yellowish white hair bands. Hair at apex very 

 pale reddish brown. 



Resembles A. montrosensis, but the facial foveae are broader. 

 They are very closely allied. 



(This differs from typical A. medionitens by the redder, and I 



think rather narrower, facial foveae, and red middle tarsi, but I can 



not believe it to be a distinct species. In the key it falls in a couplet 



with perezana, from which it is separated thus : 



Scopa appressed and hiding tegument perezana. 



Scopa not appressed, not hiding tegument; tarsi stramineous., medionitens, variety a.) 



b GS . Hind tibiae and tarsi not clear red. (Tarsi red in astragali and medionitens, 



variety a.) 

 a 70 . Large species, considerably over 10 mm. long, with, conspicuous white hair-bands ; 



species superficially similar. 

 a 71 . Wings orange. (See A. astragali, above.) 

 6 71 . Wings not at all orange. 



ANDRENA TOWNSENDI, new species. 



Dripping Spring, Organ Mountains, New Mexico. August 10. 

 (C. H. T. Townsend.) 



Female. — Length, 13 mm. Black, the tarsi brownish, their small 

 joints becoming ferruginous as well as the anterior knees. Pubes- 

 cence grayish white, clear ocherous on thorax above. Facial 

 quadrangle broader than long. Process of labrum strongly emargi- 

 nate. Clypeus shiny, sparsely punctured, with a poorly denned 

 smooth median band. Facial foveae seen from above light ochreous, 

 moderately broad, ending broadly below at about level of top of 

 clypeus. The clypeus is very high and the supraclypeal area very 

 small, so that the antennae are inserted very near to the top of the 

 clypeus. Scape reddish at base ; flagellum obscurely reddish beneath. 

 Third antennal joint a little shorter than next three combined. 

 Meso thorax dull and granular, scarcely punctured. Scutellum sinn- 

 ing in front. Area of metathorax granular, with a depressed median 

 line. Tegulae rufopiceous. Wings brownish hyaline, the nervures 

 and small stigma reddish, the stigma very dark. Basal nervure 

 falling short of transverse median. Second submarginal very broad, 

 receiving first recurrent nervure slightly beyond middle. Hair of hind
