This species is widespread in Canada 
and the type series included specimens 
from Nova Scotia, Ontario, Alberta, 
and British Columbia, 
Specimens recorded here from North 
Carolina and Tennessee agree exactly 
with A. vockerothi .

Agromyza sp. (Wyoming) 
A single female from Wyoming, Teton 
County, Tugwater Pass, "shrubby 
vegetation along stream," 17. VII. 61 
(J. G. Chillcott), in CNC, appears to 
represent an undescribed species. 
However, it is also close to A. 
johannae de Meijere, a leaf miner on 
Cytisus and more rarely Genista and 
Lupinus in Europe (see Spencer, 1976a: 
116). Positive identification is not 
possible in the absence of a male. 
Essential characters of this species 
are as follows: Frons reddish in 
front, darker behind, orbit black; 2 
ors, 2 ori; gena deep, slightly less 
than 0.33 height of eye; 3d antennal 
segment small, round, blackish, 1st 
and 2d paler, more orange; mesonotum 
matt gray, 3+1 strong dc, acr 
irregularly in 4-5 rows, prsc strong; 
legs largely black, only foreknees 
reddish; squama and fringe whitish; 
wing length in female 2.4 mm, C 
extending strongly to M 1+2, last and 
penultimate sections of M 3+4 equal. 
GENUS PHYTOBIA LIOY 
One new species is described, one new 
synonym is established, and one 
species is recorded as new to the 
United States. New State records are 
given for one species, and one 
possible new species on Salix is 
briefly discussed. 
Phytobia calyptrata (Hendel) 
(Figs. 481, 482) 
Agromyza nigrisquama Malloch, 1916: 53. 
Holotype female from Illinois in 
INHS. 
Agromyza calyptrata Hendel, 1923: 145, 
new name, not nigrisquama Malloch, 
1914c (Formosa). 
Phytobia ( Trilobomyza ) calyptrata , 
Frick, 1953a: 70; 1959: 393. 
Phytobia septentrional is Spencer, 
1969a: 106. Holotype male from 
Quebec in CNC. NEW SYNONYM. 
The generic position of the holotype 
of this species has previously been in 
doubt. Although Frick (1959) placed 
it in Phytobia , he was using this name 
in the sense of Dizygomyza Hendel, 
1931, and he included it in the 
subgenus Trilobomyza (now in 
Amauromyza ) , whereas in Frick's sense 
it would correctly belong in the 
subgenus Dendromyza . It is one of the 
smallest of the true tree-feeding 
Phytobia species, and its identity is 
revealed by the conspicuously silvery 
lunule . 
A male has now been examined from 
Maryland, Montgomery County, 
Colesville, 15. IX. 76 (A. S. Menke), in 
UCD, which agrees exactly with the 
female holotype from Illinois, and it 
is now apparent that JP. septentrional is 
Spencer, known from Quebec and Ontario, 
represents the same species. This new 
synonymy is established here. 
Z* calyptrata agrees closely with P. 
californica , but with available ma- 
terial, treating the two as distinct 
appears justified.
