cephalon. 
Thorax blue black, moderately silvery pollinose, with black 
longitudinal stripes on dorsum; pleura lightly dusted with gray 
pollen; propleuron with black setae; preacrostichal and predorso- 
central bristles before suture by 2.2 and 1.6 respectively; pro- 
sternum with black hair; preparapteron orange, with white 
pubescence; other sclerites at wing-base black; greater ampulla

brown tawny hair; lateral postscutellar plates with black setae; 
under surface of scutellum laterally with fine black hair. 
Legs black. . 
Wing hyaline, rather brown basally; costal sections 2 to 6 in 
the proportions 94:60 :1388 :48:10; subcostal sclerite orange, with 
orange pubescence; basicosta black; fourth vein without apical 
section or fold; upper squamal lobe white at base, rim brown; 
lower squamal lobe brown, rim white. 
Abdomen black with bluish luster, strongly silvery pollinose, 
tessellated. 
Genital segments black, shining, with black setae. Internal 
anatomical features (pl. 27, D) as illustrated. 
Female. Head width 18.0; length at antenna 8.0 and at 
vibrissa 8.2; eye height 8.7; head height 13.0; bucca 0.48 eye 
height; frontale with considerable scattered black hair, 0.59 
frontal width; front with nearly parallel margins, at vertex 
(which is narrowest) 0.38 of head width and 0.42 at lunule; 
parafaciale 2.8 in width opposite lunule, black, with brownish 
pollen; vibrissae set 3.5 apart; palpus 4.8 in length; third seg- 
ment of antenna 3.4 times as long as second. Legs with bristles 
usually longer and finer than in male; the claws shorter. Wing

Abdomen with marginal bristles on fourth segment more erect 
than in male. Otherwise similar to male except for sexual 
differences. 
Length. 8-14 mm. 
Distribution. Palearctic: Hong Kong and Hankow, China to 
Siberia. Nearctic: Southern California to northwestern Oregon. 
Adults have been collected during almost the entire year at 
Nice, Calif., by A. W. Lindquist. 
Biology, habits, and rmmature stages. None of the habits or 
details of the biology of this species are known. Lindquist’s ecol- 
lections were made in a blowfly trap baited with decaying meat 
and the habits of the species must be essentially similar to those 
of Calliphora vomitoria.
