wing margin, sixth and seventh distinct; legs yellow, spurs of pos-

Much as I regret the creation of genera for the reception of single 

 species, there seems no other way out of it, as the insect does not fall 

 within either Plastophora or Syneura, as defined by Brues, differing 

 in several essential characters from both of those genera.

 APHIOCH.ffiTA FENESTRATA, new species, ' 



Female. — Black, subshining; frons about one-fourth longer than 

 broad, upper post-antennal bristles close together, of moderate size, 

 under pair small, center pair of bristles in first row much nearer to 

 center of frons than outer pair and about equidistant from those and 

 upper post-antennals; antennae yellowish, third joint round, arista 

 pale, as long as frons, pubescent, palpi yellow, of moderate size, with 

 4-5 bristles; mesonotum thickly covered with short hairs, about 6

Locality. — United States National Museum, Washington, District 

 of Columbia, on window, May 28, 1912 (J. R. Malloch). 



Very close to divergens, but the above description sKould serve to 

 separate them. Owing to the presence of four scutellar bristles 

 fenestrata will run down to arcuata in the table of species given in 

 Group D on page 452. 



APHIOCH.ffiTA SCHWARZI, new species. 



Female. — Black ; frons one-third longer than broad, sHghtly shining, 

 punctured, and with the surface covered with numerous short hairs, 

 two pairs of convergent post-antennal bristles, the under pair about
