range until the moths had emerged. The majority of the affected animals recovered 
under this treatment. The older hogs either had not acquired a liking for the juicy 
pupae or were better able to take care of the indigestable silk fibre of the cocoon.’’ 
The above article reveals an interesting result from an outbreak of Malacosoma 
disstria (Hub.), examples of which are not uncommon. Tent caterpillars have 
been unusually abundant in the coast counties this year but the above record is the 
only one reported of injury to grazing stock.

Gracillaria zachrysa Meyr., attacks Apple Foliage in Northwestern India. The 
following letter has been received from Mr. T. Bainbrigge Fletcher, Imperial Ento¬ 
mologist, Agricultural Research Institute, Pusa, Bihar, India, dated July 31, 1918: 
Dear Doctor Howard: 
“In the Proceedings of our Second Entomological Meeting (p. 248) I have referred 
to a Gracillariad caterpillar attacking apple leaves in Northwestern India. We were 
able to obtain moths later on and I have now received its identification by Mr. Mey- 
rick as Gracillaria zachrysa Meyr. As I note that this insect has lately been imported 
into the states on Azaleas from Japan via Holland, I think it is as well to let you 
know this at once in case it should become acclimatized and turn its attention to 
apples with you also. 
“The same or a very similar species (specimens have only emerged today and I 
cannot compare them critically until they are off the setting boards) is also common 
on apple at Shillong, in Assam (N.E. India) so that it seems possible that this insect 
occurs in all the apple growing districts along the Himalayan region and, as these 
localities have mostly a very hard winter, there is the less reason why G. zachrysa 
should find difficulty in acclimatizing itself in the states. At present I gather (Entom. 
News, XXIX, 114) that it is chiefly a greenhouse pest.” 
Under date of August 2, 1918, Mr. Fletcher adds: 
“In continuation of my letter of July 31, I have now examined the adult of apple 
Gracillariad from Shillong (Assam) and make it to be G. zachrysa, as supposed, the 
Assam species agreeing exactly with others from N. W. India named by Meyrick.” 
Mr. Fletcher’s communications will be of decided interest to American entomolo¬ 
gists in view of the establishment of this insect in the United States.

Caribou Warble Grubs Edible. There is an interesting reference in the October 
1918 Ottawa Naturalist by R. M. Anderson to the edibility of caribou warble grubs. 
He states that the Eskimos pick out the grubs from the hides in the spring and eat 
them like cherries and adds, apparently from experience, that they are very watery 
and absolutely tasteless. This is not so very different from the report of some 
months ago upon the “white grub sandwich,” only fewer “trimmings” appear ta 
be necessary.
