where the elephant has been domesticated for an indefinite length 
of time. 
It was described by Fiaget (Tijdschr. voor. Ent., 
2d series, IV, 254) in 18G9, under the name of llama- 
lomyzus elephantis. The same author, however, in 
his elaborate monograph, Lcs Pediculines, changes 
the name to H. proboscidean. This louse differs from 
the others of the family in having a slender pro- 
longed snout extending in front of the head. The 
antennae are located at the base of this snout, and 
according to Murray are lenticular in form. In 
Piaget's figure, however, they appear of nearly equal 
thickness throughout. " Color reddish, madder brown, smooth, shining, 
impunctate. ?, (Murray.)

TECHNICAL DESCRIPTIONS OF NEW SPECIES. 
LOUSE OF THE FIELD MOUSE. 
{Hcematopinus acanthopus Burm.) 
Apparently common on our species of Arvico.a, and does not appear 
to vary in any important particular from the descriptions of European 
specimens. 
DESCRIPTION OF THE EGG. 
**Wr^ 
The egg in this species, unlike those of other forms we have met, is 
bundle of hairs instead of to one, our specimen thus 
having attachment to four hairs, as showninFig.il. 
This would seem to he an excellent provision where the 
hair is so fine as in these animals. 
The egg is elongate oval, broad, and somewhat trun- 
cate at the attached end; the surface is roughened, 
rugulose, or foveolate appearing squamous in places, 
and in section showing rounded pits on the surface; 
the investing substance at base is slightly corrugated. 
See Fig. 11 e. 
The larva is much shorter and thicker in proportion 
than the adult, the spiny hairs of the abdomen wanting. 
but with one or two long slender hairs extending back 
from the terminal portion.
