Liriomyza dianthi Frick 



Liriomyza dianthi Frick, Proc. Ent. Soc. Washington, vol. 60, No. 1, p. 1, 

 1958 (figures of head and pleura) . 



This species is very black with relatively few yellow markings. It is 

 similar to Liriomyza quadrisetosa and L. baptisiae, but differs in having 

 the third antennal segment mostly yellowish and darkened distally. 

 L. dianthi is very similar to L. langei but is darker over-all, having the 

 mesepimeron and pteropleuron black or very dark grayish, the femora 

 about three-fourths black, and the scutellum narrowly yellow with 

 the distal scutellar setae being on the black triangles or not more 

 than a setal base removed from them. L. dianthi is at present confined 

 to the San Francisco Bay Area of California. The larvae make 

 large white serpentine mines in the leaves of Dianthus caryophyllus L. 



Liriomyza discalis (Malloch) 



Agromyza discalis Malloch, Ann. Ent. Soc. Amer., vol. 6, p. 277, 1913 (figure of 

 head) . 



This is a very dark species of Liriomyza that has the pleura black 

 except for the sutures. The head has the inner vertical seta on yellow 

 and has a few sparse reclinate orbital setulae (fig, 106). The margin 

 and fringe of the calypter are white. The holotype is from Arizona 

 and is the only known specimen. 



Liriomyze eupatorii (Kaltenbach) 



Argromyza eupatorii Kaltenbach, Die Pfanzenfeinde aus der Klasse der Insekten, 



p. 320, 1874. 

 Liriomyza eupatorii (Kaltenbach), Frick, Canadian Ent., vol. 85, p. 72, 1953. 



This is a Holarctic species that is little known in North America. 

 It is close to Liriomyza munda and L. verbenicola in having the 

 genovertical plates yellow. The most obvious distinction of L. 

 eupatorii is crossvein m-m being 1.5 to 2 times its length from r-m, 

 m-m being about at its own length in the other two species. The 

 larvae make serpentine mines, usually beginning as a spiral, in 

 Solidago spp., including elongata Nutt. in Washington. In Europe 

 also found mining species of Eupatorium, Lampsana, and Galeopsis. 

 Thus far found only in Washington. 



Liriomyza felti (Malloch) 



Agromyza felti Malloch, Ent. News, vol. 25, p. 310, 1914. — Frost, Mem. Cornell 

 Univ. Agr. Exp. Sta., vol. 78, p. 43, 1924 (figures of leaf mines). 



The holotype male is in the collection of the New York State 

 Museum, Albany, N. Y. The head has the black of the occiput 

 broadly reaching the eye margin and the eye is smoothly rounded 

 anteriorly (fig. 107). This species differs from Liriomyza commelinae 

 in having the gena centrally about one-fifth the eye height (about
