Diptera 71 c 
apex of abdomen, the length of wing equal to that of entire insect; costa with 
short black setulse, the costal spine not differentiated; outer cross- vein curved; 
last section of fourth vein twice as long as preceding section. 
Length, 8 mm. 
Type localit}': Bernard harljour, Dolphin and Union strait, Northwest 
Territories, June, 1915-16 (F: Johansen). 
AUiopsis, sp. 
Female. — Similar in colour to obesa. 
Frons at narrowest part about one-eighth the width of head, the orbits 
linear and about one-fifth as wide as interfrontalia, bristles as in preceding species; 
profile as PI. X, fig. 32, Thorax much less conspicuously haired than in obesa, 
the dorso-centrals stronger and well differentiated; presutural acrostichals 
irregularh^ four-rowed, presutural bristle single; prealar as in obesa, nearly as 
long as the bristle behind it; scutellum with a differentiated discal pair of bristles 
in addition to the marginals. Abdominal hairs very long on lateral margins of 
segments and on apical two, short on disc, the contrast more striking than in 
obesa; apical genital segment without thorns. Legs less hairy than in obesa, the 
bristles on tibiae strong and distinct; fore tibiiB with three long bristles, one on the 
anterior dorsal surface and two on the posterior; mid tibiae with three antero- 
dorsal, four to five postero-dorsal, and three postero- ventral bristles; hind 
femora as in obesa, but hind tibiae with four to five long bristles on the basal half 
of posterior surface in addition to those on the other surfaces, the latter stronger 
than in obesa. Wings as in obesa, but the costal setulae are longer, the costal spine 
is distinct, and the outer cross-vein is straight. 
Length, 7-5 mm. 
Locality: Camden bay, Alaska, June, 1914 (F. Johansen). 
It is possible that the two foregoing forms represent only one species. 
The genus AUiopsis was erected for the reception of the European arctic 
species glacialis Zetterstedt, and is closely allied to Lasiops Meigen, both having 
the eyes very distinctly hairy, but it may be separated from that genus in the 
male by much more widely separated eyes, those of Lasiops being subcontiguous, 
and by the very broad abdomen. The female of Lasiops has the frons similar to 
that of Phorbia, whereas that of AUiopsis is not much wider in the male and all 
the orbital bristles are directed slightly inward, none directed forward. 
Egle Kobineau-Desvoidy. 
This genus contains several species that have been placed in Anthomyia by 
most authors. From the tj^pe of the latter Egle differs — at least the species 
known to me — in having the prothorax bare below and in front of the spiracle. 
One species is present in this collection. 
Egle radicum (Linne). 
Musca radicum Linne, Fauna Suec, 2d ed., p. 454, 1756. 
Six specimens, with data as follows: Nome, Alaska, August 21, 1916, two 
specimens, and August 24-25, 1916, three specimens; and Teller, Alaska, July 
29,, 1913 (F. Johansen). 
This is a European species which occurs throughout North America and 
has previously been recorded from Alaska. 
Schnabl and Dziedzicki have erected the genus Paregle for the reception of 
the above species and several others, but I do not think the separation warranted.
