AGROMYZID LEAF MINERS — FRICK 405 



one-third in commelinae) and in a small dark ventral spot on the 

 anepisternum. The larvae make blotch mines in the leaves of the 

 ferns Camjptosorus rhizophyllus (L.) and Asplenium pinnatifidum Nutt. 

 Known from Illinois and New York.

This species may be distinguished from the other species in the 

 so-called pusilla complex by having the femora basally black for 

 two-thirds of the length and yellow distally. The anepisternum is 

 about one-half black with the dark area triangular. The abdomen 

 is broadly yellow laterally. The larvae mine the leaves of grasses 

 and I have reared it from Bromus carinatus H. & A., Hordeum 

 murinum L., and Lolium multifiorum Lam. Thus far this Holarctic 

 species is known in North America only from central California.

Agromyza melampyga (Loew), Melander (part), Journ. New York Ent. Soc, vol. 

 21, p. 258, 1913 (Icf, New Mexico). 



A rather large species (2.5 to 2.75 mm. in wing length) that has the 

 geno vertical plates extending beyond the eye margin. The mesono- 

 tum is didl but not pollinose and bears four developed dorsocentral 

 setae, all on yellow. The abdomen is mostly yellow. None of the 

 three kno\vn specimens has been reared. All are from New Mexico 

 and Melander's is from Cloudcroft at an elevation of 9,000 feet. 



Liriomyza fumicosta (Malloch) 



Agromyza fumicosta Malloch, Ent. News, vol. 25, p. 310, 1914. 



Unique among Liriomyza species in having the costal area light 

 brown (fig. 108). The mesonotum is slightly lighter brown centrally 

 than the marginal stripes, there are two sparse rows of acrostichals, 

 and the scutellum is entirely yellow (fig. 109). There are two known 

 specimens, both from IDinois.
