smeared molasses on a piece of. cardboard, gummed it in 
the bottom of a small box and, while the molasses was still 
fresh, clapped it over the insects. Their jumping brought 
them into contact with the sticky surface, and there they re- 
mained secure and alive till they reached the office. Mr Ford 
stated, under date of May 31, that this species was particularly 
injurious to melon and squash vines. The general form of the 
insect, though much enlarged, is shown in the accompanying 
figure. It is a broadly oval, black or dark colored insect less 
than 4. of an inch in'length, wingless but provided with short, 
thick hind thighs and also a peculiar, ventral springing fork. 
The latter structure is peculiar to insects belonging to the same 
order, Thysanura, and it is on account of this peculiar organ, 
that these insects are frequently known as “ springtails.” Dust- 
ing affected plants thoroughly with plaster or ashes or, better 
still, spraying them with a poisoned bordeaux mixture should 
~ control the pests. | 
Rabbit botfly, Cuterebra ?cuniculi Clarke. This 
species, closely related to the “ warble fly ” of cattle, which is 
frequently known as “ grub-in-the-back,” was twice brought to 
notice during the season—once, when infesting Belgian hares, 
and in this instance the identification was in all probability 
correct. The second case was that of a kitten four months old, 
owned by D. F. Meskil of Highland Falls N. Y. The history of 
the case as stated by Mr Meskil is as follows. About Aug. 7 
the kitten “ developed an abrasion on his side, midway between 
the hind and fore quarters and 1 inch below the spine. It 
rapidly developed into a suppurating protuberance,” and by the 
16th it was “an inch and a half long and as thick as a man’s 
thumb.” It will be noted that this is just about the position 
where this larva develops on the rabbit. The sore was cut open, 
and a grub ¢ of an inch long and nearly half an inch in trans- 
verse diameter removed. The grub resembles the one from the 
Belgian hare very closely, and they probably belong to the same 
species. It only remains to add that the kitten recovered 
rapidly after the removal of this disgusting pest. The accom-
