Liriomyza haptisiae (Frost) 



Agromyza haptisiae Frost, Canadian Ent., vol. 63, p. 275, 1931. 



The holotype male is in the U. S. National Museum (No. 62962). 

 The type series is in rather poor condition but this species belongs 

 to those species that have the third antennal segment at least partially 

 dark and lack the prescutellar yellow spot on the mesonotum. This 

 is a small species (1.25 to 1.5 mm. in wing length) that has the third 

 antennal segment totally black, the femera distally yellow, and the 

 wing with crossvein m-m about twice its length from r-m. The larvae 

 form linear-blotch mines in the leaves of Baptisia iinctoria (L.) in 

 Pennsylvania. 



Liriomyza barrocoloradensis (Frost) 



Agromyza barrocoloradensis Frost, Ann. Ent. Soc. Amer., vol. 29, p. 300, 1936. 



The holotype male is in the U. S. National Museum (No. 62967). 

 The head in profile is similar to that of Liriomyza sorosis (fig. 125). 

 The mesonotum is shining and is marked much like that of L. mel- 

 ampyga (fig. 113) except that the marginal dark stripes are light 

 reddish. The anepisternum is entii'ely yellow. The larvae mine the 

 leaves of an unidentified plant in the Panama Canal Zone. 



Liriomyza borealis (Malloch) 



Agromyza borealis Malloch, Ann. Ent. Soc. Amer,, vol. 6, p. 280, 1913 (figures of 

 head and wing). 



The head of the holotype is partially collapsed but posteriorly the 

 gena is as wide as the eye is high. The maxillary palpus is yellow. 

 The mesonotum is marked as in the figure and the basal pair of 

 scutellar setae arises from yellow (fig. 101). This species is known 

 only from the holotype from British Columbia. 



Liriomyza brassicae (Riley) 



Agromyza brassicae Riley, U. S. Dep. Agr. Ann. Rep. (1884), p. 322, 1884. 

 Liriomyza brassicae (Riley), Frick, Pan-Pacific Ent., vol. 33, p. 68, 1957. 

 Agromyza diminuta (Walker), Coquillett (part), U. S. Dep. Agr., Div. Ent., Bull. 



10, p. 78, 1898 (specimens from cabbage). 

 Phyiomyza mitis Curran, Canadian Ent., vol. 63, p. 97, 1931. 

 Agromyza subpusilla Frost (part) (not Malloch, 1914), Journ. New York Ent. 



Soc, vol. 51, p. 255, 1943 (figure of mine of nasturtium leaf). 



Liriomyza brassicae belongs to the group having yellow antennae, 

 both varietal setae on the dark color of the vertex, and the genovertical 

 plates darkened between the orbital setae and the eye margin. Of 

 the tliree species in this group, L. brassicae, L. propepusilla, and L. 

 pictella, the latter two have the anepisternum at least one-half dark, 

 the dark area being subrectangular. The anepisternum of L. brassicae 

 is subtriangular. The larvae mine the leaves of a large number of
