HELEOMYZID FLIES NORTH OF MEXICO—GILL 505 
Suillia quinquepunctata (Say) 
Figure 5 
Helomyza quinquepunctata Say, 1823, p. 97.—Aldrich and Darlington, 1908, p. 91. 
Helomyza latericia Loew, 1862a, p. 227 (Centuria 2, 89). 
Suillia quinguepunctata (Say), Czerny, 1924, p. 36. 
This species resembles Suillia limbata (Thomson) and S. sororcula 
Czerny in that the cheek is very narrow, the cheek-eye ratio being 
0.25 or less. In S. quinquepunctata (Say) the dorsum of the scutellum 
is almost completely covered with hairs, and serves to distinguish it 
from the other two species. 
MALE AND FEMALE.—Color similar to that of S. limbata (Thomson); 
head higher than wide, the ratio of width to height being about 0.7; 
third antennal segment ovoid; aristae plumose; about 2 irregular 
rows of buccal setae; no orbito-antennal spot; cheek-eye ratio 0.25 or 
less. 
Thoracic chaetotaxy similar to S. limbata (Thomson), except 
scutellum is almost completely covered with setae or hairs (may be 
bare near the base) and the mesopleuron is bare; legs with forefemora 
thickened, more so in the male; wings with anterior and posterior 
crossveins and the ends of the second through the fourth longitudinal 
veins clouded with brown. 
Lrenatu.—About 6.0 mm. 
Distrisution.—Throughout eastern United States from Ontario 
to Florida; records as far west as Nebraska, Kansas, and Texas; 
March—Novemner. 
Suillia apicalis (Loew) 
FIGURE 6 
Helomyza apicalis Loew, 1862a, p. 226 (Centuria 2, 86). 
Suillia apicalis (Loew), Czerny, 1924, p. 14.—Steyskal, 1944, p. 175. 
In this species the mesopleuron has only a very few setae along the 
posterior border, and the scutellum has the setae or hairs of the dorsum 
confined to the lateral edges. This combination of characters will 
distinguish Swillia apicalis (Loew) from related species. 
MaLr AND FEMALE.—Front yellowish orange; ocellar triangle, 
vertex, and back of head reddish orange, often with grayish pollinosity ; 
antennae reddish yellow, aristae dark brown to black, short pubescent; 
third antennal segment ovoid; face, cheeks, and mouth parts yellow; 
oral vibrissae strong, buccal setae in 2 or 3 irregular rows; no orbito- 
antennal spot; cheek-eye ratio about 0.33. 
Mesonotum reddish orange with faint grayish pollinosity; setae or 
hairs of scutellum confined to lateral edges; pleura yellowish orange
