recumbent narrow, elongate golden-brown 
scales; supra-alar line of light azure-blue scales 
as figured, anterior scales small, almost circu- 
lar in outline, becoming more elongate cau- 
dally, posterior scales narrow; acrostichals 
weak, other scutal bristles strong, all dark, 
supra-alars few in number. Scutellum brown, 
median lobe very prominent; median lobe 
with three strong bristles, scales short, round- 
ed, projecting only slightly over base of bris- 
tles; lateral lobes each with one weak and 
two strong bristles, scales elongate, projecting 
strongly over bases of bristles. Postnotum 
brown, darker centrally. Pleural integument 
light brown; scaling and chaetotaxy as fig- 
ured; scales light azure-blue on apn and mid- 
dle sternopleuron, patches in line with light- 
scaling of head and a light integumentary 
area caudad of apn; scales of apn short, 
rounded anteriorly, elongate, pointed in small 
caudal patch; scales of middle sternopleuron 
smaller, almost circular in outline; scales on 
lower sternopleuron practically transparent; 
larger bristles dark, shorter, golden brown. 
Haltere light on base, darker on stem dis- 
tally, knob dark-scaled. 
Wing: Distance between cross veins 1.7 of 
m-cu. Vein R2 about 0.4 of R 2 + 3 ; vein M1+2 
about 0.6 of M beyond m-cu. White scales 
dorsally on caudal margin of R to slightly 
beyond arculus, on basal 0.3 of Cu, and on 
base of lA; remaining dorsal scales dark, 
much darker on costal and radial fields, iri- 
descent bronzy. 
Legs: Coxae light, with few translucent scales 
and light hairs and bristles; trochanters light, 
with a few hairs; femora dark-scaled above, 
lighter below; tibiae entirely dark-scaled; front 
and mid tarsi entirely dark-scaled, appearing 
lighter ventrally in some lights; hind tarsus 
white-scaled on entire segments 3-5 and the 
extreme apex of 2. Leg I: femur 1; tibia 1.0, 
with small tuft of specialized scales and elon- 
gate bristles; tarsus 0.85, 0.50, 0.36, 0.14, 
0.07; claws equal, one thickened, other elon- 
gate. Leg II: femur 1.14, moderately swollen; 
tibia 1.70, with three short stout bristles api- 
cally; tarsus O.9O, 0.53, 0.30, 0.09, 0.09; claws 
as on I, Leg III: femur 1.30, very slender; 
tibia 1.30, with specialized scales on swollen 
apex; an inconspicuous light patch subapical- 
ly on external face; tarsus 1.20, 0.60, 0.40, 
0.20, 0.10; claws minute. 
Abdomen: Tergites completely dark, scales 
iridescent bronzy; sternites light-scaled, con- 
trasting sharply with tergites, especially ba- 
sally. 
MALE (921-301).— Wing: 1.75 mm. Pro- 
boscis: 1.33 mm. Front femur: 1.10 mm. 
Generally very similar to female. Vertex of 
head more extensively dark-scaled, orbital 
light line narrow dorsally, more conspicuous- 
ly enlarged laterally to apn. Proboscis more 
strongly swollen apically. Flagellar whorls 
about 0.28 of flagellum, with about 12 bris- 
tles. Light-scaling on wing indistinct, dingy 
white. Leg I: femur 1; tibia 0 . 92 , specialized 
bristles on apex as figured; tarsus 0.54, 0.40, 
1.10, 0.40, 0.12, specializations as figured; 
claws equal, one strongly swollen. Leg II: 
femur 1.28, strongly swollen; tibia I.9O; tarsus 
0.92, 0.66, 0.23, 0.06, 0.17, segment 4 with 
long ventral lobe projecting below base of 
5; claws enlarged, shorter claw about 0.9 of 
larger and more slender, slightly curved; larg- 
er claw strongly curved. Leg III: femur 1.38; 
tibia 1.52; tarsus 1.42, 0.78, 0.53, 0.28, 0.13; 
claws as on foreleg. 
MALE GENITALIA (921-301) . —As figured. 
Ninth tergite expanded, without bristles; 
proximal part strongly emarginate in the mid- | 
die and with sclerotization evanescent; apical i 
part more shallowly emarginate, poorly de- I 
fined, short, broad lateral lobe; a strong ven- ^ 
trolateral sclerotization from apex of lateral 
lobe toward basal arm of sidepiece. Proctiger I 
with weak lateral sclerotizations. Basal lobe i 
of sidepiece with a dorsal group of three large 
and one small specialized bristles arising from 
tubercles, ventrally with one specialized long 
bristle arising from a tubercle. Clasper as fig- 
ured, apex of spine broken off. Mesosome 
with a poorly sclerotized ventral bridge in 
addition to strongly sclerotized dorsal bridge;
