Trichodcctec aermsi ICellpg a he. Nakayama. These lice are cap- 
able of depositing eggs so 'that the mohair becomes matted and 
is of a poor quality. The quantity of hair actually lost as 
a result of the lice is one with which the ranchman is most 
familiar. He estinated that during each six month a single 
dipping of the goats increases the yield of mohair about one- 
fourth of a pound to each animal. This represents from 14 to 
20 cents on each clipping, or from 28 to 40 cents per animal 
during each year. ' 
Practically every ranch is provided with a dipping vat, but 
the present practise of dipping the animals does not effect 
a permanent control of lice. Following a single dipping, some 
of the eggs hatch and the infestations increase. Owing to the 
long period of incubation for L. stenopsis , a single dipping 
is less effective for this species. Since the latter is a blood, 
sucking form, there is a loss in ""eight and vitality of the 
animal s .
