on Galeopsis , Lamiaceae) , and the leaf 
mine commences with a distinctive 
spiral (see Spencer, 1981: fig. 313). 
In America, typical mines (fig. 790) 
have been found on Aster chilensis in 
California, Alameda County, Albany (K. 
E. Frick). Longer mines are also 
frequent on Solidago (Washington 
County, Miss.), with the initial 
spiral minute or more frequently 
entirely lacking (fig. 791). No 
differences can be found between the 
adults from Solidago and Aster or in 
their male genitalia, and the Solidago 
feeder is therefore treated as L. 
eupatorii despite the dif ferent~form 
of the leaf mine. 
The species has hitherto been known in 
the United States only in California 
and Washington. Study of additional 
material now shows that L. eupatorii 
is widespread also in the Southern 
States. During a visit to Mississippi 
in May 1979, leaf mines were common on 
Solidago , but all were recently empty 
in mid -May.

Liriomyza flavonigra (Coquillett) 
(Figs. 633, 634) 
This species was described from two 
females from New Mexico, and an addi- 
tional male was subsequently recorded 
by Me lander (1913: 258) at an 
elevation of 9,000 feet (Frick, 1959: 
405). The latter is now mislaid. 
Coquillett (1902) gave the wing length 
of the female as 3 mm, whereas Frick 
(1959) recorded it as 2.5-2.75 mm. 
Distinctive characters of the species 
are the projecting frons (see Malloch, 
1913a: pi. XXX, fig. 27) and 
the yellow squamal fringe. Two males 
have been seen from Utah, Cache 
County, Providence, 25.V.64 (G. F. 
Knowlton) , in UCD. They agree in 
these and other characters, but they 
are somewhat smaller, with a wing 
length of 2.3 mm. It seems reasonably 
certain that they represent L. 
flavonigra . The distinctive aedeagus 
is shown in figures 633, 634.

Liriomyza helianthi Spencer, 1981: 240. 
Holotype male from California in CAS. 
The type series was caught on 
Helianthus annuus and it seemed 
probable that this was the host. 
Additional specimens reared from this 
host and also from Xanthium strumarium 
in Washington have been examined and 
identified as L. helianthi .
