AGROMYZID LEAF MINERS FRICK 411 



Liriomyza tubifer Mclander 



Liriomyza tubifer Melander, Journ. New York Ent. Soc, vol. 21, p. 266, 1913. 



This species is similar to Liriomyza horealis in coloration but differs 

 in having the maxillary palpus brown and the gena narrow, posteriorly 

 not more than one-fom-th the eye height. The mesonotum has the 

 yellow of the intraalar row reaching anteriorly about two-thirds of 

 the distance to the transverse suture. There is a single female in 

 Melander's collection from Haiti. 



Liriomyza variata (Malloch) 



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

 of wing). 



The holotype female is in the Museum of Comparative Zoology 

 (No. 27062). This species is close to Liriomyza reverberata in having 

 the mesonotum subshining and not pollinose. However, both post- 

 alars are subequal in length and the head has the maxillary palpus 

 dis tally darkened, three lower-orbitals, and the third antennal segment 

 subquadrate and distally darkened (fig. 126). The wing has vein 

 R2+3 undulating (fig. 127) . Known from a single specimen from Maine. 



Liriomyza verhenicola Hering 



Liriomyza verbenicola Hering, Notulae Eut., vol. 31, p. 43, 1951. 



The holotyije female is in the U. S. National Museum (64301). 

 The type is in very poor condition and the head has turned black 

 probably due to slow drying conditions following death. Therefore, 

 the charactei-s used to separate this species from Liriomyza munda are 

 OD the mesonotum. L. verbenicola has a short inner postalar seta 

 (about one-fourth to one-thu-d the outer) and has very few (about five) 

 setulae in the intraalar row posterior to the transverse suture. The 

 larvae form serpentine mhies in the leaves of Verbena sp. The type 

 series is from New Mexico. Hering has a mined leaf from Salt Lake 

 City, Utah, that he identified with this species. 



8. Genus Metopomyza Enderlein 



Metopomyza Enderlein, Tiervv. Mittelenropas, vol. 6, No. 3, p. 180, 1936. 



This is a small genus closely related to Liriomyza. There are about 

 seven Palaearctic species and one from North America. Metopomyza 

 is characterized by the wide, prominent genovertical plates that are 

 abruptly raised above the plane of the frontal vitta (fig. 128). Lirio- 

 myza deceptiva has these plates prominent but they are proportionately 

 narrower except immediately dorsad of the antenna (fig. 1 04) . Species
