furrow throughout its length. 
Mesonotum. 2 dc, acr in some 8 rows. 
Wing. Length from 2.1 mm in male to 
2.5 mm in female, C extending to M 1+2, 
last and penultimate sections of M 3+4 
equal, inner crossvein at distal 3d of 
discal cell. 
Color. Black; frons matt, ocellar 
triangle, and orbits moderately 
shining; mesonotum and abdomen only 
moderately shining; squama gray, 
margin and fringe black. 
Male genitalia. Aedeagus as in figures 
242, 243; sperm pump with large, asym- 
metrical blade.

Holotype m. , Virginia, Hawksbill, 
Shenandoah Natl. Park, 3,600-4,050 ft, 
7. VI. 62 (J. R. Vockeroth); paratypes 
1 m. , 1 f., same data. Holotype and 
f. para type in CNC, m. paratype in KAS. 
Remarks. Although this species 
generally resembles both 0. quinta and 
0. obstipa , there are small but 
significant external differences and 
the aedeagus is entirely distinctive. 
Ophiomyia vockerothi Spencer, new 
species

Head (fig. 262). Frons narrow, little 
wider than eye width, not projecting 
above eye in profile; 2 ors, 2 ori, 
orbital setulae sparse, reclinate;

6 rows. 
Wing. Length in male 1.9 mm, last 
section of M 3+4 little shorter than 
penultimate, inner crossvein only 
slightly beyond midpoint of discal 
cell . 
Color. Ocellar triangle moderately 
shining; mesonotum and abdomen shining 
black; squama gray, margin and fringe 
black.

Co., Highlands, 3,800 ft, 22.V.57 (J.

Remarks. This species somewhat 
resembles 0. texana , but the male 
genitalia of the two are entirely 
distinct . 
GENUS JAPANAGROMYZA SASAKAWA 
One new synonym and one new combina- 
tion are established here. 
Japanagromyza rutiliceps (Melander), 
new combination 
(Figs. 319-321) 
Agromyza rutiliceps Melander, 1913: 
261. Holotype male from Montana in 
USNM. 
Agromyza irwini Spencer, 1981: 113. 
Holotype female from California in 
CAS. NEW- -SYNONYM . 
This species has the appearance of a 
typical Agromyza , with reddish, 
strongly projecting frons, deep gena, 
and 3+1 strong dorsocentral bristles. 
In Japanagromyza , normally the frons 
is black or brown and does not 
project, the gena is narrow, and there 
are invariably only two postsutural 
dc. However, with males now available, 
the aedeagus has been found to be 
atypical of Agromyza and, with the 
coiled distiphallus , closely resembles 
that of a number of Japanagromyza 
species, such as J. inaequalis 
(Malloch) in Florida (fig. 336). The
