SUBFAMILY CALLIPHORINAE 241 
weak setae between vibrissae; parafaciale opposite lunule 0.7 in 
width, much wider below, and with thin yellowish silvery pollen 
over orange brown ground color; faciale nearly straight in pro- 
file and with several rows of short black setae which ascend 
about one-third the distance to the antennal base; vibrissae 0.5 
above the oral margin and set 2.3 apart; proboscis 6.0 in length, 
haustellum 3.0; palpus yellow to orange, 3.5 in length; antenna 
with first and second segments orange brown to brown, third 
segment 3.8 times as long as second, reaching 0.85 of the dis- 
tance to the vibrissae; arista brown and with long ‘black cilia 
for 0.85 its length; back of head black, with yellowish white 
pollen around the occiput, with one row of postocular cilia and 
considerable whitish yellow hair, especially below on metacepha- 
lon. 
Thorax shining metallic blue green, sometimes strongly blue 
with greenish reflections, and often with bronze-colored reflec- 
tions in certain lights, usually with very thin whitish pollen 
anteriorly and on pleura; humeral bristles three; preacrostichal 
and predorsocentral bristles two, the posterior one in each row 
placed 2.8 and 1.4, respectively, before the suture; preintraalar 
bristles two or three, the foremost sometimes absent; presupra- 
alar bristle one; propleuron and prosternum with tawny hair; 
postalar declivity with a small tuft of black setae near middle; 
selerites at wing base dark brown to black; postacrostichal bris- 
tles two; lateral postsecutellar plates with black setae. 
Legs brown to brownish black; anterior femur and tibia as in 
sericata; middle femur with one anterior bristle near middle, 
about three anteroventral bristles, one at basal fourth, one at 
basal third and one at middle, and about four posteroventral 
bristles toward base; middle tibia with one anterodorsal bristle 
near apical third, two posterior bristles, one near basal third 
and one near apical third, and two posterodorsal bristles, one 
near basal third and one near apical third (1 of 10 specimens 
without basal bristle); posterior femur with anterodv.sal and 
anteroventral rows of bristles (anteroventral row usually with 
bristles at base and apex considerably longer than those near 
middle), and with about three posteroventral bristles toward 
base; posterior tibia with an anterodorsal row of short fine bris- 
tles (usually two or three of these longer), usually two antero- 
ventral bristles, one at about basal third and one between middle 
and apical third (1 of 10 specimens without basal bristle), and 
with two posterodorsal bristles, one near basal fourth and one 
near apical third. 
Wing hyaline, brownish anteriorly, considerably so at base;
