European species in addition to those described here, and find in all 
the more or less horseshoe-shaped surstyli not found in Morpholeria. 
Spanoparea has been confused with Neoleria, but the relative lengths 
of the fronto-orbital bristles will separate these genera. 
I have not included a key to the North American species of Spano- 
parea because I am able to distinguish the species only by means of 
the male terminalia.

[?]Leria discolor (Loew), Aldrich and Darlington, 1908, p. 84. 
Spanoparea walkeri Garrett, 1925b, p. 3—Czerny, 1930, p. 445. 
Mauzu.—Head, thorax, and legs yellow to yellowish orange; 
mesonotum sometimes yellowish gray; abdomen yellowish brown 
to dark brown. 
Anterior fronto-orbital bristle one-half to three-fourths the height 
of the posterior fronto-orbital bristle; vibrissae strong; 1 row of buccal 
setae; aristae short-pubescent, dark brown; cheek-eye ratio from 
0.25 to 0.35. 
Mesonotal bristles all strong; acrostichal setae sparse, in about 3 
irregular rows; 1-3 setae on mesopleuron behind propleural bristle; 
1 sternopleural bristle with 1 or more setae in front of it; middle of 
sternopleuron bare, but long hairs between the coxae; remainder of 
pleura bare; no prosternal bristles. 
Legs with femora swollen; middle tibiae with 2 or 3 strong ventral 
apical bristles. 
Wings entirely byaline. 
FEMALE.—Similar to male except the femora only slightly swollen. 
LenerH.—4.0 mm. 
DistriBpuTion.—British Columbia, Colorado (at altitude of 11,000 
feet), Wyoming, Michigan, Quebec, New Hampshire, Maine; June-— 
September. 
Remarks.—Aldrich and Darlington (1908) determined a series in 
the U.S. National Museum as Leria discolor (Loew). The specimens 
were from New Hampshire. I have examined what is probably the 
same series and found it to be S. walkeri Garrett, as shown by the 
male terminalia. The identity of the females is, of course, open to 
question; therefore I have included reference to Aldrich and Darlington 
under both S. walkerit Garrett and S. discolor (Loew).
