a larva of Celodasys unicornis sent from Lenox, Ohio, August 18, with 
the complaint that they were doing considerable injury to plum foliage. 
Conotrachelus nenuphar was reared July 19 and 21 from sweet cher- 
ries taken from an orchard near Wooster June 19. In sour cherries 
the species seemed much later, and the larve entered the ground July 
15 from fruit purchased from a Wooster market July 12, and an adult 
appeared August 8. From the larve infesting the sweet cherries four 
examples of Sigalphus curculionis Fitch were reared. 
From a lot of Japan walnuts and chestnuts received by the Storrs & 
Harrison Company, Painesville, Ohio, April 4, direct from Japan, a 
species of mite was found in immense numbers. Through the courtesy 
of Dr. Howard it was determined at the United States Department of 
Agriculture by Mr. Banks as belonging to the genus Tyroglyphus, but 
was not siro, longior, nor agilis. 
Larvee of Papilio troilus were found at East Cleveland, Ohio, July 31, 
1896. These pupated on the following dates: August 5, imago issued 
August 22, 1896; August 1, 1896, imago issued April 10, 1897; August 
15, 1896, imago issued April 23, 1897; the pupal period covering, respec- 
tively, 17, 253, and 251 days, all pupe having been kept under the same 
conditions during the entire time. Larve of Papilio cresphontes, taken 
while feeding upon rue ( Thalictrum), gave imagoes April 14, 1897, and 
July 6, 1897, showing a variation, under precisely like conditions, of 
fifty-two days. 
The larve of Onectra distincta Wlsm. (probably) worked serious 
injury during the present year to young plum grafts in nursery rows 
on the grounds of the George Peters Company, nurserymen at Troy, 
Ohio. These larve would fasten together the terminal leaves of the 
young shoot, that was intended for the leader and expected to form the 
trunk of the future tree, and, living within this inclosure, not only 
devoured the leaves but the tip of the young, tender growth, thereby 
destroying the tree. Adults issued from these June 5 to 10, and these 
moths deposited eggs for a second brood. 
A section of apple twig was received from Arlington, Ohio, June 8, 
1896, containing a larva of Oberea bimaculata, boring longitudinally 
therein. This twig was spliced upon another of a similar size growing 
upon a small tree in the insectary. The larva continued its course 
downward in the living wood, eating out the heart and leaving only a 
thin cylinder of wood and bark. Round holes were eaten through the 
walls of this cylinder, at intervals, through which the excreta was 
ejected in filiform masses made up of oblong sections, usually of about 
one-sixteenth of an inch in length. Sometimes these would fall to the 
ground detached from each other and at other times they might be 
observed in sections of several, amounting in length to about one-fourth 
of aninch. On July 24a similar larva was found in a twig of witch- 
hazel (Hamamelis virginiana), in the woods, and brought into the insee- 
tary. The voidings of the two larvex were collected between the hours
