22 THE REPORT OP THE No. 36 



of Chrysomela, viz., a well-marked variety of C. scalaris (if the normal form is 

 that found on basswood), and a very handsome form of C. philadelphica, more 

 robust than the normal form and with the ground colour rich chestnut; both of 

 these were taken on alder, feeding freely and abundant. The normal form of 

 C. philadelphica was taken in the same locality on dogwood, and €. bigshyana on 

 willow. , Later on several interesting longicorns were captured on the trunks 

 of newly-felled white pine, attracted by the fermenting sap and breeding there. 

 Other captures were made on some fallen basswood, and in fungas that had 

 freshly spread over the top of basswood stumps. A pair of longicorns, quite new 

 to your collector, was captured in alder foliage at the end of May; and in the 

 last week of June nearly fifty specimens of the beautiful Elder Borer {Desmocerus 

 palliatus). I had only once before seen this creature alive and for the benefit 

 of other collectors I will add some notes. The beetles may be looked for first about 

 June 20th in our latitude and may be taken as late as July 20th. They were 

 nearly all captured on Early Elder {Samhucus racemosa), which at this season 

 is bright with crimson clusters of ripe berries; the later species of Elder {8. 

 canadensis) having just opened its flat cymes of white blossom. The beetles love 

 to rest on the under side of the foliage, and more frequently were found in small 

 thickets of Elder within the borders and under the shadow of hardwoods. Very 

 few were found on the Late Elder and none on the blossom. 



During July immense numbers of Eose Chafers (Macrodactylus suhspinosus) 

 were observed in High Park, Toronto, feeding on the pollen of New Jersey Tea, 

 and a few on the Late Elder. About the 20th of July, some fifteen specimens 

 of Eupaqonius suharmatus were taken in Niagara Glen, breeding on the bass- 

 wood. They were all captured on the underside of the foliage, their instinct to 

 escape by dropping from their perch being utilized in their capture. 



In August, while camping in the Algonquin Park I revisited a certain bay on 

 White's Lake and found, after seven years, the same colony of Phyllahrotica 

 decorata feeding on the same clump of Skull-cap (Scutellaria galericulata) . On 

 the willow bushes adjoining the railway DisonycJia caroliniana was abundant, and 

 among the raspberry patches a very wasp-like clear-wing moth was seen quite 

 frequently. 



The President : We are sorry that this report is the only contribution we 

 shall have as a result of Mr. Morris' season's work. It is plain that he has lost 

 none of his old enthusiasm and delight in his new locality. 



Division No. 7, Niagara District — W. A. Ross, Jordan Harbour. 



As insect pests have been very numerous and troublesome this past season 

 in the Niagara District, I have before me the rather difficult task of condensing 

 what would fill a respectable volume on economic entomology , into a brief report. 



Orchard Insects. 



Apple Maggot (Rhagoletis pomonella). This year some further work was 

 done on the control of the Apple Maggot. Two Hyslop crab-apple trees, nicely 

 laden with fruit and as near alike as possible, were chosen and each was enclosed 

 in a large cheese-cloth cage. One tree was sprayed four times with sweetened 

 arsenate of lead (2-3 lbs. arsenate of lead: 10 lbs. molasses: 40 gals, water) ; the 

 other was used as a check. Forty female and nineteen male flies were liberated 

 on the treated tree and fourteen females and eleven males were confined in the 

 check cage. No eggs were la id in the fruit on the sprayed tree, whereas practically
