especially common to the region of the “‘dew claws,” where the eggs 
appear to be most commonly deposited. 
It is of about the same general shape as the short-nosed ox louse, 
though scarcely so broad and rather smaller. The dark, chitinous 
portions of the body are much restricted, so that it has a more imma- 
ture look than the eurysternus. Its maturity, however, is fully shown 
by the development of the genital organs. 
It no doubt passes through its various stages of development just as 
the related species, and so far nothing can be said as to the exact time 
required in reaching maturity. Eggs and adults were collected in 
January, but eggs carried in a vest pocket in a small vial so as to be

kept warm did not hatch. The figure will show the characteristic form 
and structure. 
The fact that this species is confined to the lower part of the legs and 
does not occur on the parts of the body covered by long wool is a very 
important one, and one which makes it an easy matter to treat the pest 
at any season of the year. The feet and legs can be washed with any 
of the effective dipping solutions, or the sheep may be driven into a 
shallow vat of the solution with enough of the solution to reach up to 
the body without wetting the wool. Dipping at shearing time for ticks 
and biting lice will destroy these also, so that if the practice of an 
annual dip is followed there should be no trouble from this new pest.

men fusiform, tapering. Length, 2.20 mm.; width of abdomen, 1 mm.
