1922] Curran: Hammer schmidtia and Brachypoda 255 



Brachyopa nifiabdominalis Jones. 

 Three specimens of this species from Washington State. 

 The color of the thorax is more slaty than in media, the third 

 antennal segment is longer and larger. In the female the front 

 is a Httle wider, the sides less parallel, more evidently dusted 

 on the black portion and therefore appearing lighter in color. 

 The legs are all reddish, the tarsi brownish red. Abdomen 

 wholly rusty reddish yellow. I could not see that the eyes of 

 the male differed greatly from media, but the chief difference 

 seems to be in the fact that the abdomen entirely lacks any 

 darker lines on the apices of the segments, more slaty color of 

 the thorax and slightly larger size. My three specimens are 

 all between 7.5 and 8 mm. 



Brachyopa notata O. S. 



Five additional specimens from Washington State and 

 Idaho. These agree with the specimen mentioned from British 

 Columbia, and may be distinct. Two additional specimens 

 from New York agree with the eastern specimens. 



Brachyopa perplexa. 



Two additional specimens from New York State agree 

 perfectly. 



Brachyopa gigas Lovett. 



A specimen from Washington State and a second frpm 

 Idaho. 



Brachyopa basilaris n. sp. 

 This species traces out to notata in the key. It is distin- 

 guished by the wholly red first two abdominal segments, the 

 remaining segments being black. Female from Washington 

 State. 



Brachyopa nigricauda n. sp. 



Traces out to dceckei Johnson in the key. Distinguished from 

 that species by the presence of six shining stripes on the dorsum 

 of the thorac, more reddish pleurse and humeri, more exten- 

 sively yellow scutellum, yellowish wings and paler legs; the 

 anterior tarsi are all blackish as are the two apical segments 

 of the remaining tarsi. 



The descriptions of these two species will be published in 

 the Kansas University Science Bulletin during the current year. 



I have also examined a male specimen of Brachyopa bicolor 

 Fallen, from Europe and can say definitely that none of our 

 North American species is conspecific.
