1913] Agromyza and Cerodontha. 333 



divergent; outer cross vein at less than its own length from inner and 

 but little beyond end of first vein; last section of fifth vein twice as long 

 as penultimate section 

 Length 2 mm. 



Type: Cat. No. 15957, U. S. N. M. 



Type locality: San Antonio, Texas, April 8, 1907 (F. C. 

 Pratt). Nothing recorded of early stages. 



This species belongs to the pusilla group, but may readily 

 be separated from any of those in this paper by the black 

 palpi, third antennal joint and legs. It is distinct from any 

 of the European species I have examined. 



Agromyza melampyga Loew. 

 This species has been bred by C. R. Jones at San Antonio, 

 Texas, from root of Plantago media. 



Agromyza citreijrons Malloch. 

 I had some doubt as to the distinction of this species from 

 hilarella Zetterstedt, but I have since examined specimens 

 belonging to the National Museum in Budapest, and consider 

 them quite distinct. Hilarella has the frons darker than 

 citreijrons, the antennae darkened on upper surface of third 

 joint, the face less receding, the eyes longer than high, the 

 wings narrower, the inner cross vein distinctly before middle of 

 discal cell, and the last section of fifth vein very distinctly 

 longer than the penultimate section, 



Agromyza longipennis Loew. 

 I have examined specimens from Europe, of geniculata since 

 writing the above, and find they are -distinct from longipennis 

 in having the legs less broadly yellow on joints, the arista 

 almost bare, as against the distinct pubescence of longipennis, 

 and the last section of fifth vein distinctly shorter than penul- 

 timate section. 



Agromyza angulata Loew. 

 Two specimens submitted as luctuosa Meigen from Buda- 

 pest represent two distinct species, one of which is very close 

 to angulata Loew. Under the circumstances I consider that it 

 is not desirable to question the retention of angulata as the name 

 for the American species.
