318 THE BLOWFLIES OF NortH AMERICA 
The following two names were supposedly used for species of 
Calliphora from North America which remain unknown to me: 
Calliphora melanaria Van der Wulp, Biologia Centrali-Ameri- 
eana, Diptera 2:295, 1896. Guerrero, Mexico, 6,000 ft. 
Calliphora praepes Giglio-Tos, Boll. R. Univ. Torino, 8:147, 
18938; Ditt. del Mess. 4:1, 1898. Mexico. 
Calliphora stygia (F.), described originally in Musca, was 
erroneously stated by Wiedemann to be from Newfoundland, 
and the species was listed as North American by Osten Sacken 
in his catalog. The type is from New Zealand, however, and 
Townsend places the species in Neopollenia.

- Male and female. Head (pl. 6, C) width slightly greater than 
height; length at antenna and at vibrissa nearly equal; eye rather 
small; epistoma slightly elongate, gently receding from clypeal 
plane and narrower than clypeus; clypeus at least twice as 
long as wide, shallow but still distinctly depressed; metacephalon 
not protuberant; frontal rows of bristles extending anteriorly 
only to lunule; inner vertical bristles strong, decussate; outer 
vertical bristles about two-thirds as long as inner in female; 
frontoorbital bristles two proclinate and one reclinate in female; 
facial carina very slightly apparent, broad, shallow, low, and 
not separating antennal bases; parafaciale nearly as broad below 
as above, setose; proboscis only slightly shorter than head height; 
haustellum half head height; palpus stout, cylindric; antennal 
base at eye middle with head in profile view, bases approximated
