is thus impossible to identify 
individual caught females.

Phytomyza new species (Colorado) 
A large, distinctive female from 
Colorado, Clear Creek County, Mt. 
Evans, 9,800 feet, Doolittle Ranch, 
3. VIII. 61 (J. G. Chillcott) , in CNC, 
represents an undescribed species, but 
the formal description is best delayed 
until a male becomes available. A 
synoptic description is given in the 
key at couplet 28. 
It is believed that this species is 
related to P. dasyops Hendel, P. 
eumorpha Frey, and P. hirta Ryddn (see 
Spencer, 1976a), which are all arctic 
species. 
Two females can be recorded from 
Alaska, Matanuska Valley, 22. VII. 32 
(C. 0. Berg), in CUI, one of which 
appears to represent P. eumorpha and 
is the first record of this species in 
North America. The specimen is mounted 
with its puparium (but no indication 
is given of the host). This is brownish 
orange, with the distinctly enlarged 
posterior spiracles characteristic of 
species feeding on hosts in an aquatic 
environment (see P. dasyops , Spencer, 
1976a: fig. 719). The second specimen 
can be tentatively identified as ]?. 
dasyop s, having yellow femora and 
pilose eyes, and this is also new to 
North America. 
Phytomyza new species ( Ligusticum ) 
(Fig. 1360) 
Two females were reared from leaf 
mines found on Ligusticum grayi , 
6. IX. 78, at Sagehen Creek, Nevada 
County, Calif., 27 and 29. IX. 78 
(KAS). The frons is dark, the two ors 
appear to be equal (although there is 
some irregularity and the upper may be 
weaker), the mesonotum is grayish with 
acr in four rows, and the foreknee is 
yellowish. The second costal section 
is variable, less than three times and 
more than 2.5 times the length of the 
fourth. On this diagnosis the species 
runs to couplet 114 and externally 
resembles ]?. glabricola , a leaf miner 
on Ilex , with which it is not related. 
The larva forms a narrow linear mine, 
following the serrations of the leaf 
(fig. 1360), pupating externally; the 
puparium is black. Leaf mines have 
been found in Alaska on Ligusticum by 
Griffiths, and these may represent the 
same species. 
It is not proposed formally to describe 
this species until further clarifica- 
tion is possible from the examination 
of a male. 
GENUS CHROMATOMY I A HARDY 
Eight new species are described and 
one new combination is established. 
In addition, four species are recorded 
as new to the United States. The 
status of one species, C. regalensis , 
is clarified in view of its previous 
assessment as a nomen dubium. 
Chromatomyia clemativora Coquillett, 
new combination 
(Figs. 1098, 1099) 
Phytomyza clemativora Coquillett, 
1910: 131. Holotype male from Texas 
in USNM. 
The male genitalia indicate that this 
species correctly belongs in 
Chromatomyia to which it is now 
transferred . 
C, clemativora was reared, presumably 
from leaf mines, on an unidentified 
Clematis sp. It somewhat resembles £. 
clematiphaga , a leaf miner on (}. 
Columbiana and verticillaris , known 
from Montana and western Canada, but 
it is smaller, with a wing length of 
1.4 mm in the male (not 1 mm as stated 
by Coquillett in his description) to 
323
