HELEOMYZID FLIES NORTH OF MEXICO—GILL 559 
Male and female.—Gray-brown, a dark brown stripe from the ocelli to the 
antennae, leaving only a pale narrow line by each eye; face and cheeks yellow; 
1 vibrissa, with a single row of hairs behind. Front orbital bristle equal to the 
hind one, Antennae darker, segment 3 round and mostly black; arista short, 
about as long as the eye; cheek deep square; head below eye narrowed in the 
lateral view. 
Thorax and pleura brown to dark brown. Dorsum with 4 to 5 dorsocentral 
bristles. The posterior pair longest, then gradually diminishing to the suture, 
where they are often absent. Many setulae, 1 humeral and 2 pair of scutellar 
bristles. Pleura bare except a few hairs below the disk near the 1 or 2 propleural 
bristles. Sternopleura on top with 1 bristle and a row of hairs in front of it, the 
whole middle bare and many bristles between the coxae. Abdomen black. Legs: 
all femora swollen, much polished and deep red yellow, looking black; fore femora 
with top and bottom row of bristles; hind femora with no bristles. Tibiae and 
tarsi red yellow. Hypopygium very similar to that of P. ruficauda and P. 
fuscolinea. 
Holo-, allo-, and paratypes. St. Paul Isle, Alaska, 10 male, 2 female. A male 
and female from Funk Isle, Newfoundland differ in many ways, but until I get 
more males I cannot say if they are P. minuta Zett. Type No. 139, Garrett coll. 
Neoleria diversa (Garrett) 
Postleria diversus Garrett, 1925b, p. 4. 
Neoleria diversa (Garrett), Czerny, 1930, p. 447. 
This species is known only from the single type female in the Garrett 
collection (labelled Neoleria divisus). It is type 146, collected at 
Marysville, British Columbia, 14 August. The original description 
with typographical errors corrected, is quoted here; however, the 
cheek-eye ratio is actually 0.39. 
Female.—Head, occiput, also back of head red yellow, front orange; front 
orbital bristle nearly as long as the hind one. Antennae red yellow, segment 3 
round, arista brown, perhaps a little longer than the vibrissae, the latter being 
rather long. Eye large, the cheek one-quarter the diameter. Thoracic dorsum 
brown, with 4 long equal dorsocentrals, prescutellars short. Pleura black brown. 
Propleura with 1 long bristle. Sternopleura with 1 long bristle and a long hair 
in front, the rest bare except bristles between the coxae. Abdomen black to 
brown black, marginal bristles short and few. Halteres yellow. Wing hyaline, 
veins yellow brown, costal bristles short, as short as the hairs; legs red yellow, 
the last tarsi dark, femora not enlarged, the hind one with 1 bristle on top near 
the apex. Mid-tibial spurs short and nearly straight. Marysville, August. 
Type No. 146, G. Coll. 
Neoleria fuscolinea (Garrett) 
FiGgureE 57 
Postleria fuscolinea Garrett, 1921, p. 124. 
Neoleria fuscolinea (Garrett), Czerny, 1924, p. 126. 
Czerny (1924) noted the resemblance of this species to Neoleria 
ruficauda (Zetterstedt); however, I compared N. fuscolinea (Garrett) 
with European specimens determined as ruficauda (Zetterstedt) and 
found them to be different.
