Amoebaleria gonea Garrett 
FicurE 86 
Amoebaleria gonea Garrett, 1925a, p. 3.—Czerny, 1930, p. 448. 
The type of this species is a male specimen collected at Bull River, 
British Columbia, 28 Oct. 1923. I have seen the specimen in the 
Garrett collection. A series of 9 males and 6 females of this species 
are in the U.S. National Museum. They were collected at Logan 
Canyon, Utah, 19 Dec. 1918. Another male in the U.S. National 
Museum was collected at Chicago, Ill., 30 Mar. 1952. This species is 
best distinguished by the appearance of the male terminalia. 
MaLEeE AND FEMALE.—Front orange, brownish toward vertex; 
frontal plates, ocellar triangle, vertex, and upper half of back of head 
grayish pollinose; third antennal segment brownish, aristae dark brown 
to black; remainder of head dirty yellowish orange; anterior fronto- 
orbital bristle about one-half the height of the posterior bristle; 
buccal setae in about 2 irregular rows; cheek-eye ratio about 0.66. 
Thorax dark gray, brownish on pleura; mesonotum with humeri 
yellowed, a dark brown median vitta and dorsocentrals arising from 
dark brown spots which may take the form of vittae; scutellum may 
be slightly yellowed; all dorsocentrals about equally strong; several 
hairs in anterior corner of mesopleuron; sternopleuron with one 
strong bristle, the remainder of sternopleuron covered with fine hairs, 
becoming longer ventrally between the coxae; legs reddish brown; 
wings hyaline, with faint brownish tinge; abdomen reddish orange to 
dark gray pollinose. 
Lenetu.—6.0-7.0 mm. 
DistTRIBUTION.—See above. 
Amoebaleria glauca (Aldrich) 
Figure 84 
Leria glauca Aldrich, in Aldrich and Darlington, 1908, p. 87. 
The type of this species is a female and cannot be distinguished 
with certainty from A. caesia (Meigen). The abdomen is a little more 
brownish and the scutellum is partially yellowed. Accompanying the 
type in the U.S. National Museum is a male specimen determined by 
Aldrich as ‘“Leria glauca Ald.” It appears similar to the type in 
coloration and chaetotaxy; the terminalia are different from any
