12 THE CANADIAN ENTOMOLOGIST. 



into a warm room, hoping to hasten their development. On the 2nd of April, I was 

 rewarded by finding in the box a very fine female specimen of that handsome 

 grey geometer, Amphidasys cognataria, Guenee, which had escaped from one of 

 the chrysalids, and was the first of the species I had seen alive since 1864. 



I had thus no less than six different species preying upon my currants and 

 gooseberries, viz.: Wematus ventricosus, Ellopia ribearia, JSgeria tipuliformis, 

 Angerona crocaotaria, Grapta progne, and Amphidasys cognataria. Of these, 

 the saw-fly, Nematus ventricosus, was decidedly the most destructive. There is 

 still another insect, a dipterous fly, which I have not yet seen in my garden, but 

 observed in others some years ago, and which lives in the fruit of the red and 

 white currant. The history of this fly I hope to investigate during next summer. 



HINTS TO FRUIT GROWERS. 

 Paper No. 1. 



BY. V. KAUNDEES, LONDON, ONT. 



To make the Extomologist more interesting and useful to fruit growers, it 

 is intended to devote a page of every number issued during the summer season 

 to giving practical hints in reference to insects whose times of appearance may be 

 near at hand, with a condensed summary of such means and remedies as have 

 been found most serviceable in lessening the numbers of such as are injurious. 

 We shall be glad to receive communications from fruit growers, relating to any 

 new insect pests occurring in their neighborhood. 



The Plum Curculio {Conotrachelus nenuphar). Now is the time to try 

 Rausom's method of trapping the curculio. It may be practiced any time during 

 May and continued with success till early in June. Have the ground made quite 

 smooth and clean for several feet around the base of the tree, and place a few 

 pieces of chip, bark or shingle close around and against the trunk. These will 

 afford convenient hiding places for the insect. They should be turned over and 

 examined once or twice a day, when the curculios will be found attached to the 

 under side, and they can be picked off and destroyed. 



It is not expected that this will supersede jarring entirely, but will no 

 doubt, if persevered in, prove a valuable means towards lessening the numbers 

 of this terrible foe to plum culture. 



The Tent Caterpillar (Olisiocarnjja americatta). The ring-like nests of eggs 

 of this species, so common on the twigs and small branches of fruit trees, are now 

 hatched, and the young caterpillars forming webs in which to shelter them- 

 selves. If allowed to proceed and grow without interference, they will soon 

 strip the branches of the trees on which they are located entirely bare, and thus 

 produce an unsightly deformity as well as check the vigor of the tree. Where 

 the affected branches are low, the webs may be removed by the hand and the
