SUBFAMILY CALLIPHORINAE 301 
27, Savonoski, Naknek Lake, Alaska, by J. S. Hine. The species 
is not uncommon in Alaska during July and August. 
The first impression of mortica is one of the striking similarity 
of this form to small specimens of vomitoria and terrae-novae, 
both of which also have black buecae. The presence of numerous 
reddish or tawny hairs before the metacephalic suture of vomi- 
toria satisfactorily separates it from mortica, which also has the 
head entirely black, and has only the faciale, vibrissal angle, 
palpi, and small portions of the antennal segments orange red. 
The species terrae-novae has the vibrissal angle orange to orange 
red. The male genitalia of mortica and the parafaciale-vibrissal 
proportion are also distinctive. 
Biology, immature stages, and habits. Unknown.

The type specimens of nigribasis Macquart, a male and a 
female, are now in the Paris Museum. Although the labels on 
these specimens indicate that they were collected in Mexico, I 
have not seen the species from North America. Macquart’s de- 
seription states that the type was from Colombia. 
Shannon (1926, p. 184) synonymized Townsend’s Calliphora 
trazuana with peruviana, but the former is possibly a synonym 
of Calliphora terrae-novae Macquart. 
Calliphora peruviana Macquart (Diptéres exotiques, vol. 4, p. 
216, 1851) is a synonym of Neta chilensis (Walker). 
A normal Calliphora with the bases of the wings darkened.

brissa 8.7; eye height 9.3; bucca 0.86 eye height, black, silvery 
pollinose, with black hair, no pale hair before the metacephalic 
suture; frontale deep mahogany red, about as wide as para- 
frontale at narrowest, but about twice as wide anteriorly; front

lunule, black, with silvery pollen, and with a few scattered long 
black hairs outside frontal row; frontal row consisting of 10 to 
12 bristles which are hair-like posteriorly, the rows diverging 
more rapidly than margins of frontalia, and descending almost
