24 ENTOMOLOGICAL NEWS [Jan., '15 



hypopygium very small with concealed appendages ; incisures of the 

 abdomen narrowly black; bristles of the thorax of moderate length, 

 those of the abdomen short ; pleurae greenish black. 



Fore coxae yellow ; middle and hind coxae black ; trochanters, femora, 

 tibiae and tarsi yellow; fore and middle tarsi a little darker towards 

 the tips and with the fifth joints white; hind tarsi blackened from the 

 tip of the first joint, about three-fourths as long as their tibiae, first 

 joint nearly as long as the remaining four joints together, fourth 

 shorter than the fifth, about as broad as long, fifth a little flattened, 

 nearly orbicular in outline, deep black ; middle and hind tibiae with a 

 small bristle on the basal third ; hind tibiae and tarsi with rather long 

 hairs. 



Halteres yellow; tegulae brown with black cilia. 



Wings hyaline, only slightly tinged with gray ; venation as in $. 

 flavipes Aid. 



$ . Two females taken with the males described above have the 

 face more blackish; fifth joint of fore and middle tarsi are not white; 

 hind tarsi normal ; the abdomen more golden green than in the male. 



Described from three males and two females taken by Mr. 

 Nathan Banks, at Falls Church, Virginia, July 4th and 6th. 

 He took one male at Sea Cliff, Long Island, New York. Type 

 in the collection of Mr. Nathan Banks. 



This interesting little species, which I dedicate to its captor, 

 could easily be mistaken for 6\ flavipes Aid. which it resembles 

 in size and color, but in that species the fifth joint of all the 

 tarsi is black, while in this species the fore and middle tarsi 

 have the fifth joint white, contrasting with the darker joints 

 which precede them; the hind tarsi do not have the fifth joint 

 flattened as in this species. I think it would be difficult to sepa- 

 rate the females of the two species. 



Sciapus bradleii n. sp. 



First two joints of the antennae yellow; abdomen with yellow at base; 

 wings with the apex flattened in outline and with the front apical cor- 

 ner rounded ; costa with erect cilia. Length 4.5 mm.
