not been taken in the crown of the stiiiwberry, so I'ar us the avaihible 
records and material indicate. The strawberry crown-miner, on tlie 
other hand, may be more gjeneral in feediii.^- liabit, bnt in the matter of 
rehitionship to the former does not, in tlie hirval state, show any close 
kinship, and more resembles a tortricid than a tineid larva. 
The moths of the strawberry crown miner, judging from tlie fact of 
their being generally classed with lincatelhiy must be very similar in 
appearance to the latter insect. Mr. Cordley says, however, that when 
alive their habits are not at all alike, although as dry, mounted objects 
they are very ditticult to distinguish. The twig-borer moths are, how- 
ever, slightly larger and darker coloied. He says: 
Those reared from the strawberry erowus crawl down amoug the viues, even into 
crevices in the soil, apparently for the purpose of depositing eggs upon the crowns, 
and when disturbed run or flutter about with wings half spread. On the other 
hand, the moths of the twig borer invariably take an elevated position in the breed- 
ing cage, and with the fore part of the body slightly raised and 
the labial palpi held rigidly upright in front of the face they 
present a very characteristic and alert appearance. When dis- 
turbed they dart rapidly about, suddenly alighting again in the 
same characteristic attitude upon another portion of the cage. —

We have evidently, therefore, a str a wberiy insect en. 
tirely distinct from the old Anarsia lineatella of Europe 
and this country which infests stone fruits. The former 
seems undescribed, so far as the adult is concerned, 
although its habits are fairly well ascertained. It is 
highly desirable, therefore, that some of our specialists 
in microlepidoptera should give it a good descrii^tion and ^^^- ^ 7 ' "^^* 
name, if it proves not to have been hitherto characterized, enlarged (origiiiai) 
NATURAL PARASITES. 
That this insect is attacked by parasites during its hibernating period 
has already been alluded to, and in fact, of the material received from 
Mr. Ehrhorn, nearly all of the larvie had been destroyed by a minute 
predaceous mite, Pediciiloides ventricosus {^g. 5). In most cases nothing 
remained of the larv.T except the empty head. 
Professor Comstock in his studies of the peach twig-borer reared a 
parasite from it which he did not name, but which was later described 
by Dr. L. O. Howard as Copidosoma variegatum. 
A new i)arasite of Anarsia was obtained from the material in tree 
crotches submitted by Mr. Ehrhorn, which Mr. Ashmead has identified 
as his species, Oxymorpha livida. The specimens reared from the twig- 
borer are smaller than the type, but the sj^ecies is a wide-spread one 
and quite varmble in point of size. 
Of these i)arasites 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 larvie.
