that it is distinct, though closely related. PJiaseoU has the head 

 almost similar to that of riparia, the orbital hairs very weak, the 

 vibrissae comparatively stronger, the cheek narrower, the eye more 

 elongate, and the venation different, the inner cross vein being but 

 slightly beyond the middle of the discal cell and the last section of 

 fourth vein 4 times as long as penultimate section. Length: 1 mm. 

 Pupa: Colored as that of gihsoni, but more glossy. Setulse indis- 

 tinguishable, posterior spiracles as fig. 1 1 . 



AGROMYZA EUPATORIAE, new species. 



Closely resembles gihsoni, but separable by the following charac- 

 ters: The 4 pairs of orbitals are comparatively stronger and more 

 equal in length; the eyes of the male are slightly pubescent above, 

 the cheeks are linear in the male, slightly higher in the female, the 

 last sections of the third and fourth veins are more regularly and 

 decidedly divergent; the penultimate section of fourth vein in the 

 male is slightly over one-fourth as long as ultimate; in female it is 

 nearly one-fourth as long as ultimate and the outer cross vein is 

 straight (in gihsoni it is very slightly but distinctly bent outward 

 at middle). In other respects similar to gihsoni.

 dark brown ; wings clear, veins black. 



Head in profile as figure; frons one-third the head width, slightly 

 narrowed anteriorly, its length about IJ times its width; orbits well

 more than one-fifth as wide as center stripe; 

 orbital bristles 4 in number, the lower 2 pairs 

 slightly incurved ; orbital hairs numerous ; frontal 

 triangle glossy and well defined, not extending to 

 middle of frons; mouth margin produced as in 

 figure. Mesonotum with 2 pairs of dorso-central fig. i2.-AGR0MiZA coni- 

 bristles; discal setulge numerous, about 12 irreg- ^^^^- P'^-^^ o^ ^^^^^ 

 ular rows between the dorso-centrals, continued 

 to the transverse level of posterior dorso-centrals; scutellar bristles
