New Nearctic Mecoptera

Female : length, 5 mm. ; color as in male ; pilosity sparse, 
especially on abdomen; wing pads yellow, covering hind 
wing scars ; ovipositer one and one-half times the length of 
the beak. 
This rare species, of which only four specimens are 
known, has not been collected outside of the type locality, St. 
Paul Island, Bering Straits, Alaska. It closely resembles 
the fuscus var. of calif ornicus, but differs in the bronze col- 
oration and the brilliant shine of the abdomen.

Proc. Bost. Soc. Nat. Hist., 8:408; 1871. 
Male : length 3.5-4 mm. ; wings light yellow to light brown ; 
eyes gray, rest of body brown, usually more or less bronze in 
color ; body covered with fine, short, white pubescence, 
nearly absent from abdominal terga ; fore wings abruptly 
narrowed at about the middle ; hypandrium entire, broadly 
triangular; rostrum one and one-half times as long as the 
eye. 
Female : length 5 mm. ; color 1 similar to that of the male, 
wing pads yellow to light brown; fine, short, white pilosity 
covering body, but much reduced on abdominal terga ; ovi- 
positor one and one-half times as long as the rostrum ; fore 
wing pads covering hind scar. 
A study of the specimens of calif ornicus now at hand 
shows that there is much variation in the coloration of these 
insects, some having the body definitely brown and the 
wings yellow ; others, the body black and the wings brown. 
The type specimens, all from Ft. Bidwell, Siskiyou County, 
California, are of the former class, with brown bodies and 
yellow wings in both sexes. A series of 7 specimens from 
Goose Lake, Siskiyou County, are somewhat similar, though 
the bodies are a dark brown and the wings a light brown. 
These seem to me to represent the typical calif ornicus. The 
darker specimens have been found only in more northern 
regions (British Columbia, Alberta and Montana) and ap- 
pear to me to deserve a varietal rank, designated here as 
fuscus.
