appears to be no other published record of the species, except a 
series of 11 specimens reported by Sabrosky. The latter specimens 
were collected 16 Nov. 1946 and 13 Nov. 1947 from the nest of Huta- 
mias amoenus affinis, Rocky Flat, 16 miles northwest of Naches, 
Yakima County, Wash. The Garrett collection contains two ad- 
ditional records (both males): Cranbrook, British Columbia, 22 Sept. 
1923; Moscow, Idaho, 28 Aug. 1916. 
The following incorporates the original description and the ad- 
ditional notes of Sabrosky (1949). 
MaLE AND FEMALE.—Front 1.9 to 2.1 times as broad as an eye, 
orange anteriorly, becoming reddish posteriorly; fronto-orbital plates 
and ocellar triangle bright gray and rather sharply demarcated; oral 
vibrissae strong, a single row of buccal hairs or setae; cheek-eye ratio 
0.55. 
Thorax grayish black, with brown shading; thoracic chaetotaxy as 
given in generic description; legs reddish yellow; distal 4 segments of 
the foretarsus somewhat broadened and flattened, those of the other 
tarsi slender and elongate; middle tibia with a row of 3 to 6 short 
bristlelike anterodorsal hairs extending from the distal end toward the 
middle of the tibia, these hairs only a little longer than the ordinary 
clothing hairs on the tibia but somewhat thickened and suggestive of 
a row of tiny bristles; hind femur of male without a row of strong 
posteroventral spines, but with an irregular row of short semierect 
hairs that are slightly thicker than the ordinary appressed clothing 
hairs of the femur; wings often mutilated, with only the basal portion 
remaining; second vein of wing near but not closely apposed to the 
costa; hind crossvein only half its length from margin of wing; abdomen 
reddish yellow. 
Lenetu.—3.0—4.5 mm. 
Lutomyia hemiptera (Curran) 
Criddleria hemiptera Curran, 1929, p. 32.—Czerny, 1930, p. 440. 
Lutomyia hemiptera (Curran), Sabrosky, 1949, p. 3 (fig. 5). 
This species was described from specimens found in the nest of 
Thomomys talpoides rufescens. The species name was suggested 
by the mutilated wings of the type series, in which all but the basal 
portion is torn off. 
This species is similar to the preceding, but may readily be dis- 
tinguished by the relatively small eye. The cheek-eye ratio is 1.0 
in the five specimens I have measured. The middle tibiae have 
several strong anterodorsal bristles. The male has weak hairs 
ventrally on the hind femur, but is without distinct spines. The 
male terminalia are similar to Lutomyia distincta Garrett, except 
distally the hypandrium is narrow, less than one-half the width of
