AGROMYZID LEAF MmERS — FRICK 391 



both in Europe and the United States. Frick (1956b) reported the 

 larvae mining Penstemon procerus Dougl., family Scrophulariaceae, 

 in CaHfornia. The species is widely distributed in the United States 

 and Canada. 



Phytobia (Calycomyzd) ipomoeae (Frost) 



Agromyza ipomaeae Frost, Ent. News, vol. 42, p. 74, 1931. 



The type series is teneral and therefore rather difficult to charac- 

 terize fully. However, the forefemur is distally yellow for a distance 

 subequal to its diameter and the midfemora and hindfemora are 

 reddish distally. These characteristics separate Phytobia (Caly- 

 comyza) ipomoeae from P. (C.) ambrosiae and P. (C.) verbenae. The 

 larvae mine the leaves of Ipomoea batatas Poir. in Puerto Rico.

This species is Nearctic in distribution and is commonly found 

 throughout the United States and Canada. The larvae mine the 

 leaves of a rather large number of plants in the family Compositae. 



Phytobia {Calycomyza) lantanae Frick 



Phytobia (Calycomyza) lantanae Frick, Ann. Ent. Soc. Amer., vol. 49, p. 287, 1956. 



The larvae mine the leaves of Lantana camara L., possibly other 

 Lantana spp., and Lippia helleri Britt. This is a Neotropical species 

 known from southern Texas, Mexico, Puerto Rico, and Trinidad. 



Phytobia {Calycomyza) majuscula Frick 



Phytobia (Calycomyza) majuscula Frick, Ann. Ent. Soc. Amer., vol. 49, p. 295, 

 1956 (figures of larval characters and leaf mines). 



This is a moderately large species, the larvae of which make blotch 

 mines in the leaves of Senecio lugens var. exaltatus Gray in central 

 California. Also known from Washington, Idaho, Saskatchewan, 

 and Ontario.
