262 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.40. 



tegulae dark rufous; wings moderately dusky; b. n. just falling short 

 of t. m.; anterior femora with very long greyish-white hair behind, 

 but black below and in front; their tibiae with black and pale mixed; 

 their tarsi with black, rather reddish on inner side; middle femora 

 with long sooty hair; their tibiae and tarsi with ferruginous hair on 

 outer side and black on inner; hind femora with black hair, but 

 mostly white on upper side (white also on hind coxae and trochanters 

 beneath) ; their tibiae and tarsi with black hair on inner side and red 

 on outer, the basitarsal brush black or dark reddish; hind spurs 

 ferruginous, with lateral dark lines; apex of abdomen, around the 

 narrow apical plate, black haired; some black hair on basal part of 

 third segment, almost hidden; apical ventral segments reddish 

 haired in middle, with black hair before the red. 



Habitat. — Japan (Hilgendorf). Five females in Berlin Museum. 



Kuns in Friese's table to A. senilis Eversmann, from Russia and 

 Turkestan, but is larger, with the hair of the legs differently colored in 

 part and the tarsi dark. If it came from the mainland I should 

 think it probably a subspecies of A. senilis. Doctor Friese has 

 marked one of the specimens ll canescens 1," i. e. A. nigrocincta, var. 

 canescens Brulle, from Greece. It does accord very nearly with 

 Brulle's short description, but considering the different locality, and 

 the fact that Brulle's insect was very insufficiently described, I can 

 not assume that the Japanese species is identical. It is perhaps just 

 possible that Brulle had a Japanese specimen with the wrong locality; 

 Friese places canescens as a variety of nigrocincta without seeing 

 specimens, and if the two are really conspecific, the name canescens 

 has priority and should stand for the species. In Dalla Torre's 

 Catalogue canescens appears as a Megachile. 



ANTHOPHORA ROBBI, new species. 



Female. — Almost exactly like A. atroalba Lepeletier, but all the hair 

 on outer side of hind basitarsus black, that on outer side of hind 

 tibia silver white. It very likely deserves only subspecific rank, but 

 the male may show more difference . 



Habitat.— Pekin, China, May 7, 1901 (M. L. Robb). U. S. National 

 Museum. 



Type.— Cat. No. 13542, U.S.N.M. 



ANTHOPHORA RETUSIFORMIS, new species. 



Male. — Length about 15 mm., black, the occiput, thorax above, 

 pleura, metathorax, and first two abdominal segments with bright 

 orange-fulvous hair, not mixed with black; a little black hair on 

 vertex; hair of face pale yellowish, of lower part of cheeks long and 

 white; abdomen shining, feebly and sparsely punctured, the third 

 and following segments with black hair, apical margins of second to
