AGROMYZID LEAF MINERS — FRICK 401 



35. Mesonotum dull, heavily gray poUinose; basal scutellar seta arising from 



black of lateral triangle allia 



Mesonotum subshining, not pollinose; basal scutellar seta arising from 

 yellow, at edge of black triangle phaseolunata 



Liriomyza allia (Frost) 



Agromyza allia Frost, Journ. New York Ent. Soc, vol. 51, p. 257, 1943. 

 Liriomyza allia (Frost), Frick, Journ. Kansas Ent. Soc, vol. 28, p. 90, 1955 

 (figure of head). 



The holotype male is in the U. S. National Museum (64300). This 

 species varies from Liriomyza alliovora in having only two rows of 

 acrostichals. L. allia has the mesonotum heavily gray pollinose in 

 contrast to L. trifolii and L. phaseolunata, which are subshining and 

 not pollinose. No larval host plants are known. In addition to the 

 holotype there is a paratype male; both are from Manhattan, Kans. 



Liriomyza alliovora Frick 



Liriomyza alliovora Frick, Journ. Kansas Ent. Soc, vol. 21, p. 88, 1955 (figure of 

 head) . 



This species differs from Liriomyza felti and L. commelinae in having 

 a dark spot on the humerus and from L. allia in having four rows of 

 acrostichals. The head of L. allimra does not have the black from 

 the occiput reaching the eye margin, as does L. felti (fig. 107), and the 

 anepisternum has a ventral black area, unlike L. commelinae. The 

 larvae mine the leaves of Allium sp. in Iowa. 



Liriomyza angulicornis (Malloch)

 Liriomyza angulicornis (Malloch), Hendel, in Lindner, Die Fliegen der palaearkti- 

 schen Region, fam. 59, p. 208, 1931 (figure of head and wing). 



This Holarctic species has the third autennal segment angulate 

 dorsoanteriorly and the gena is about one-half as wide as the eye 

 height (fig. 96). The anepisternum has a long slender ventral dark 

 triangle (fig. 97). There are no known larval host plants. The 

 holotype, from Illinois, is the only known North American specimen. 



Liriomyza assimilis (Malloch) 



Agromyza assimilis Malloch, Canadian Ent., vol. 50, p. 80, 1918. 



The head is entirely yellow in profile and both vertical setae are on 

 yellow (fig. 98). The yellow prescutellar area is triangular in shape 

 (fig. 99) and the dark ventral spot on the anepisternum is ovoid (fig. 

 100). Frost has a series of specimens reared from linear mines in the 

 leaves of Helianthus sp. at Arendtsville, Pa. The holotype is from 

 Illinois.
