that there is no basis whatever for connecting them w.th the same 
insect, and in fact they probably belong to different families. 
The moths of the strawberry crown-miner, on the other hand, are 
very similar in appearance to the moths of the twig-borer, as dry, 
mounted objects. The habits of the living insects, however, of 
the two species are, on the authority of Mr, Cordley, very dissimilar. 
The twig-borer moths are slightly larger and darker colored than the 
strawberry insect, and invariably take an elevated position in the 
breeding cage with the fore part of the body slightly raised and 
the labial palpi held rigidly upright in front of the face, as elsewhere 
noted. The moths reared from the strawberry crowns, on the other 
hand, crawl down among the vines, even into crevices in the soil, appar- 
ently for the purpose of depositing eggs upon the crowns of the plants, 
and when disturbed run or flutter about with wings half spread. 
This strawberry insect seems undescribed although its larval habits 
are fairly well known. The important consideration, at any rate, is 
established that the culture of the strawberry presents no menace to 
the grower of stone fruits, since the damage under discussion to the 
two plants has no connection. 
NATURAL PARASITES. 
That the larve of the peach twig-borer are attacked by parasites dur- 
ing the hibernating period has already been alluded to, and in fact, of 
the material received from Mr. Ehrhorn, nearly all 
had been destroyed by a minute predaceous mite, 
Pediculoides ventricosus (fig. 5). In most instances 
nothing remained of the larvie except the empty heads. 
Two minute hymenoptera, or four-winged fly para- 
sites, have also been reared from the larvie. The first 
of these was obtained by Professor Comstock, who 
in his studies of the peach twig-borer reared a para- 
site from it which he did not name, but which was 
later described by Dr. L. O. Howard as Copidosoma 
variegatum. The second fly parasite of Anarsia was 
obtained from the material in tree crotches submitted 
Peace ca Doras by Mr. Ehrhorn, and proves to be Oxymorpha livida 
enlarged (original). AShmead, a wide-spread species quite variable in 
point of size. 
Of these parasites, in California the greatest benefit is derived from 
the mite, which, as we have already stated, frequently causes the death 
of from 75 to 95 per cent of the young larve. 

REMEDIES AND PREVENTIVES. 
The common method of procedure against this insect, and the one 
hitherto generally suggested, is to clip off and burn the withering 
infested tips in the spring as soon as the injury is noted. The forego-
