spp. are also attacked in Europe. The specimens that I have seen 

 are from such widely scattered localities as Washington, Colorado, 

 Massachusetts, and Ontario. 



Melanagromyza setifrons (Melander) 



Agromyza setifrons Melander, Journ. New York Ent. Soc, vol. 21, p. 260, 1913. 



In addition to the holotype from Troy, Idaho, Melander has a 

 second male from Avon, Idaho. Distinctive in having six or seven 

 orbital setae and an eye that is high and narrow (fig. 37). 



Melanagromyza similata (Malloch) 



Agromyza similata Malloch, Canadian Ent., vol. 50, p. 178, 1918. 



The holotype male from Dubois, 111., is the only specimen of this 

 species. M. similata is similar to M. simplex in having the costa end 

 at vein ^^s and with two pairs of dorsocentral setae. However, in 

 this species the genovertical plates are dull and there are only six to 

 eight rows of acrostichal setae. The dorsal upper-orbital is situated 

 very close to the vertex (fig. 38). 



Melanagromyza simplex (Loew) 



Agromyza simplex Loew, Berliner Ent. Zeitschr., vol. 13, p. 46, 1869 (Centuria 



VIII, No. 84). 

 Melanagromyza simplex (Loew), Hendel, in Lindner, Die Fliegen der palaeark- 



tischen Region, fam. 59, p. 176, 1931 (figures of head and wing). 



M. simplex can be distinguished from M. similata by the shining 

 genovertical plates and the eight to ten rows of acrostichal setae of 

 the former species. The larvae mine under the epidermis of asparagus 

 stems close to the ground level. Found wherever Asparagus officinalis 

 L. is grown, it has been reported from many States. 



Melanagromyza subvirens (Malloch) 



Agromyza subvirens Malloch, Proc. U. S. Nat. Mus., vol. 49, p. 105, 1915 (figures 

 of head and wing). 



This species is close to M. riparella in having three lower-orbital 

 setae (fig. 39), but it differs in having the penultimate section of M3+4 

 about twice as long as the ultimate. Also, crossvein m-m usually is 

 at an obtuse angle to the penultimate section of Mj+j instead of being 

 perpendicular. I have identified specimens from Iowa, Illinois, 

 Virginia, and Pennsylvania. 



Melanagromyza tamia (Melander) 



Domomyza tamia Melander, Journ. New York Ent. Soc, vol. 21, p. 258, 1913. 



M. tamia is known from six specimens from Washington. It is 

 close to M. angelicae in the arrangement of the orbital setulae (fig. 40)
