16. VI. 61; Nederland, 8,500 ft, 1 f., 
15. VI. 61; (all B. H. Poole). Holotype 
and paratypes in CNC, 2 paratypes in 
KAS. 
Remarks. This large, distinctive 
species cannot be confused with any 
others known at the present time. 
Ophiomyia carol inae Spencer, new 
species 
(Figs. 282, 283) 
Head. Frons broad, twice width of 
eye, not projecting above eye in 
profile; 2 ors, 2 ori, orbital setulae 
reclinate; ocellar triangle short, 
apex extending only slightly beyond 
apex of upper ors; gena broad, 0.33 
height of eye; vibrissal angle approx. 
90°, fasciculus in male broad at 
base, finely tapering; facial keel 
narrow, furrowed, only slightly raised. 
Mesonotum. 2 dc , acr in some 8 rows. 
Wing. Length in male 3 mm, costa 
extending strongly to M 1+2, last 
section of M 3+4 0.67 penultimate, 
inner crossvein only slightly beyond 
midpoint of discal cell. 
Color. Black, ocellar triangle and 
orbits only faintly shining; mesonotum 
and abdomen moderately shining; squama 
gray, margin and fringe black. 
Male genitalia. Aedeagus as in 
figures 282, 283. 
Host/early stages. Unknown. 
Holotype m. , North Carolina, Macon 
Co., Highlands, 3,800 ft, 7. VI. 57 (W. 
R. M. Mason), in CNC. 
Remarks. This is the largest species 
in the genus known in the United 
States, and it can be compared only 
with (). vibrissata . The two agree 
closely, but in (). carolinae the 
vibrissal fasciculus is shorter and 
more slender. The aedeagi of the two 
species are distinctively different. 
A female from North Carolina, High- 
lands, Horse Cove, 3,000 feet (H. C. 
Huckett), in CNC, agrees closely with 
the holotype, but it is smaller, with 
a wing length of 2.6 mm and is not 
treated as a paratype. 
Ophiomyia carolinensis Spencer, new 
species 
(Figs. 259-261) 
Head (fig. 259). Frons 1.5 times 
width of eye, not projecting above eye 
in profile; 2 ors, 2 ori, orbital 
sparse, reclinate; ocellar triangle 
ill defined beyond ocellar plate, apex 
just reaching level of lower ors; 
vibrissal corner forming angle of 
approx. 60°, vibrissal fasciculus in 
male short, broad at base, finely 
tapering; gena about 0.2 vertical 
height of eye (both antennae missing); 
facial keel narrow but highly raised 
at base of antennae. 
Mesonotum. 2 dc , acr in about 8 rows. 
Wing. Length in male 1.9 mm, last 
section of M 3+4 longer than 
penultimate, in ratio 19:16, inner 
crossvein at distal 3d of discal cell. 
Color. Ocellar triangle scarcely, 
mesonotum and abdomen distinctly, 
shining black; squama gray, margin and 
fringe black. 
Male genitalia. Aedeagus as in 
figures 260, 261. 
Host/early stages. Unknown. 
Holotype m. , North Carolina, Macon 
Co., Highlands, 3,800 ft, 23. VIII. 57 
(J. G. Chillcott ) , in CNC. 
Remarks. Distinctive characters of 
this species are the very high facial 
keel and the long last section of vein 
M 3+4. The male genitalia are 
diagnostic. 
Ophiomyia chondrillae Spencer, new 
species 
(Figs. 227-229) 
Head. Frons narrow, equal to width of 
253
