1913] Cockerell — A New Bee of the Genus Emphor 107 



A NEW BEE OF THE GENUS EMPHOR. 



By T. D. A. Cockerell, 

 University of Colorado. 



Mr. C. T. Brues has kindly sent me three females of a species 

 of Emphor, collected by Miss Louise Nichols at Cape May Pt., 

 N. J., Aug. 25, 1912. To my surprise, they are not E. bombiformis 

 but represent a new species. 



Emphor fuscojubatus sp. nov. 



9 . Like E. bombiformis (a cotype from Georgia compared) but differing as 

 follows: hair of vertex dark rufofuscous, instead of being ochreous like that of the 

 thorax; hair of thorax paler, not so red; hair of middle of front fuscous instead of 

 whitish; scape not red at apex; third submarginal cell conspicuously longer; hind 

 margin of first abdominal segment narrowly pale and pellucid; wings perhaps rather 

 paler. 



This is probably the Emphor bombiformis of Smith's New Jersey 

 list. 



SOME OBSERVATIONS ON THE NESTING HABITS OF 

 THE MINING BEE, EMPHOR FUSCOJUBATUS Ckll. 



By M. Louise Nichols. 



These observations were made during the last week of August, 

 1912, at Cape May Point, N. J., by Mr. Reynold A. Spaeth and 

 myself. The bees collected were thought at first to be Emphor 

 bombiformis Cress., but a closer examination by Prof. T. D. A. 

 Cockerell revealed the fact that they were sufficiently unlike E. 

 bombiformis to be classed as a new species, named by Prof. Cockerell 

 Emphor fuscojubatus, and differing from the other species chiefly 

 in the color of the hair on various parts of the body and in the 

 greater size of the third submarginal cell of the wing. It is a 

 member of the family Apidse. 



By the side of a road, for a distance of about one eighth of a mile, 

 in soil consisting of a mixture of clay, sand and pebbles, numerous 

 nest openings were discovered and between about ten a. m. and 

 four p. m. many bees flying in and out. The nest is begun as a 

 semicircular depression, the soil being moistened by a fluid from
