Mr. H. S. Smith, formerly of the Bureau of Entomology, noticed 
dipterous larvae mining leaves of lucem in fields in Sicily, Italy, and 
France during the spring of 1912, and from a pupa taken in one of these 
mines, collected in Sicily during the last week of December, 1911, reared 
A gromyza nigripes . He reports the work of this species in Europe as 
similar to that of the alfalfa leaf-miner in America with which he is 
familiar. Apparently the larva can be found mining in the lucern leaves 
in the latitude of Sicily during the entire winter. 
DISTRIBUTION OUTSIDE OF THE UNITED STATES 
Outside of the United States this species has been found in middle, 
central, and northern Europe—Italy, Sicily, Egypt, England, Scot¬ 
land, and Ireland. Its general distribution is shown in the map of the 
world (fig. 2). 
DISTRIBUTION WITHIN THE UNITED STATES 
The general distribution of the species in the United States, excluding 
Alaska and the insular 
possessions, extends 
from the coast region 
of central New Jersey 
southward to southern 
Florida and westward 
to southern California 
and northwestern 
Washington. It also 
occurs about Hono¬ 
lulu, Hawaiian Islands.
