AGROMYZID LEAi' MINERS — FRICK 409 



116). The first dorsocentral is very short and subequal to an acro- 

 stichal seta in length. The head (fig. 117), mng (fig. 118), and 

 anepisternum (fig. 116) are illustrated in order to help characterize 

 this species, which is at present known from a single male from 

 Kansas. 



Liriomyza quadrisetosa (INIalloch) 



Agromyza quadrisetosa Malloch, Ann. Ent. Soc. Amer., vol. 6, p. 332, 1913. 



The head of this rather diverse species is subtriangular in profile, 

 and the genovertical plate is darkened from the vertex for about one- 

 third of the length and bears one upper-orbital and fom- or five lower- 

 orbitals (fig. 119). The third antennal segment is black, the femora 

 are totally brown, and the wing has crossvein m-m about one-fourth 

 of its length from r-m. There are specimens from Texas, Indiana, 

 and New York. 



Liriomyza reverberata (Malloch), new combination 



Agromyza reverberata Malloch, 1924, Canadian Ent., vol. 56, p. 191, 1921. — P>ick, 

 Univ. California Publ. Ent., vol. 8, p. 375, 1952. 



Of the four specimens mentioned in Malloch's description only one 

 could be found ; namely, a female paratype in the Canadian National 

 CoUection (No. 3398) labeled "Glen Echo, Maryland, V-14-1922 (J. 

 R. Malloch), Agromyza reverberata Paratype." The other specimens 

 were to remain in Malloch's personal collection, or so he stated. The 

 U. S. National Museum acquired Malloch's collection but the types 

 of Liriomyza reverberata were apparently missing. Because this 

 species is quite distinct, a neotype designation is unnecessary. Lelt 

 in Agromyza by Frick on the basis of the description, the species 

 belongs in Liriomyza. 



This species is most closely related to L. variata but differs in the 

 short inner postalai- seta and in having one or two lower-orbitals. 

 The mesonotum is illustrated to show the color pattern and the fully 

 developed intraalar seta (fig. 120). The wing has vein R2+3 undulat- 

 ing (fig. 121). The mesonotum is subshining but not pollinose. 

 There are three specimens from Ontario in the Canadian National 

 Collection together with the paratype from Maryland. 



Liriomyza schmidti (Aldrich) 



Agromyza schmidti Aldrich, Proc. Ent. Soc. Washington, vol. 31, p. 89, 1929. 



This species has the anepisternum entirely yellow, dark basal 

 scutellar triangles present, and both vertical setae arising from the 

 black of the vertex (fig. 122). The wing has the ultimate section of 

 vein Mi+2 curved (fig. 123). The larvae make serpentine mines in 

 the leaves of Gliricidia sepium (Jacq.) (=G. maciUata) in Costa Rica.
