The type, a female, was ko at тарах аа Province, by 
Harris. The fly is known only from this pro 
pies —ő. Length, about 9 mm. ; witg,, Tm 
Basisty 
dististyles, as in subgenus. Right зейге (r.b.) еч apically into 
long curved black spine arising from an enlarged setiferous base ; the single 
dististyle of this side (r.d.) an irregular det blade. the surface with 
as in A. fatuus, Aber immediately before a apex. 
n A. (N.) fatuus (Hutton) (fig. 12) the asymmetry is less marked, 
“ы lobes of basistyles (b) being nearly slike зр two sides ; dististyle 
of right side (r.d.) is bifid, the two arms closely appressed, the obtuse 
arm with tiay setiferous punctures. The two dere of left side very 
dissimilar in shape, the outermost (o.d.) heavily chitinized, narrowed into 
a beak that is —€— strongly upon itself and nl pointed ; face of 
this style with a series of comb-like teeth or pegs ; ond or inner style 
(i.d.) an acicular d profoundly bifid, the two с за unequal. What 
as the aedeagus seems rather to be a gonapophyse 9 
‘the other being nok reduced. The true aedeagus (a) is very similar t 
that found in subfatuus. Ninth tergite (!) has lateral lobes long, ohluuely 
truncate, margins and apices of lobes smooth.

T degree of asymmetry in male hypopygium of the two species of 
sia is very e ue being somewhat more marked in subfatuus

Edwards's type, a female, was taken at аа in September, 1906,
