Synopsis. Closely resembling P. ovalis , distin- 
guishable by shining orbit and narrow gena, 
which is 0.2 eye height; wing with 2d costal 
section twice length of 4th; male genitalia

pump with large, strongly pigmented blade.

Note. This species is possibly related to P. 
ovalis and may prove to be a leaf miner on 
Boraginaceae .

Apiaceae 
1. Angelica breweri 
California, Tuolumne Co., below Sonora 
Pass near stream beside road, 8,500 
ft, 7. IX. 78 (KAS). The mine is an 
upper surface blotch at the apex of 
the leaf segments (fig. 1359). The 
only species known to feed on Angelica 
in eastern North America are Phytomyza 
angelicae , which forms circular blotch 
mines in the center of the leaf blade 
(fig. 1237), and archangelicae
