successful : among other captures, two Liopus variegatus on fallen poplar, one 

 Lepturges querci on sumac, one Xylotrechus undulahis on spruce, two Desmocerus 

 palliaius from the same little clump of late elder as had yielded several captures 

 nearly three weeks earlier, two Oberea tripunctata and one very small and faintly 

 marked specimen of Clytantlius riiricolu on raspberry foliage. Next day, on a 

 dead branch of sumac I took a specimen of Keoclytus erythroceplialus. On July 

 6th I took a specimen of Hoplosia nuhila near Chemong from the same dead limb 

 of basswood as yielded over a score last season. On July Sth, three Liopus alpha 

 from dead or dying sumac branches, On July 11th in the heart of a large tamarac 

 swamp on various blossoms including yarrow, daisies and fleabane (feeding on 

 pollen in the hottest of sunshine) 19 Leptura chrysocoma, and on the edge of 

 the swamp in milkweed blossom, three Typocerus velutinus and two T. zehratus; 

 I strongly suspect L. chrysocoma to bore in the tamarac, for I have never found 

 it far from that tree. On July 17th, I took fifteen T. zehratus on blossom of 

 sumac and milkweed, and one Leptostylus macula on a dying branch of sumac. 



On July 18th, while with a brother botanist on a corduroy road in a tamarac 

 swamp north of Bethany, I noticed a strange butterfly that at first I took for a 

 f ritillary or silver-spot ; on capture it proved to be the very beautiful " Baltimore," 

 Melitaea pha>eton. Investigation in September showed a plentiful growth at the 

 roadside of Chelone glabra or Turtlehead, the food plant of this insect's larva. 



On July 20th, I paid a farewell visit to the " Wood of Desire " before going 

 north to camp in the Algonquin Park. The day was spent following in the wake 

 of the axe ; here were taken, running on white pine logs that lay scorching in the 

 sun, three Neoclytiis •nmricatulus (including a mating pair) ; one Urographis 

 fasciatus resting on foliage of a basswood stump; Lepturges plctus on a dying 

 branch of basswood ; these were all in the open or on the edge of the wood ; in 

 the depths among a confusion of felled hemlock, spruce and balsam, I took two 

 Leptura subhamata and three Xylotrechus undulatus all on spruce. 



The active collecting for the season came to an end between July 27th and 

 August 3rd in the Park with the capture of some Leptura canadensis and four 

 specimens of Leptura hiforxs, taken in flight about our little camp clearing on 

 Big Island in Cache Lake.

Attacking Field Crops. Wireworms, white grubs, cutworms, grasshoppers, 

 crickets. Considerable damage was done in the spring by white grubs to straw- 

 berry beds, wireworms to potatoes, cutworms to cabbage and tobacco plants, espe- 

 cially to the latter; a considerable acreage of tobacco had to be replanted on 

 account of the ravages of the cutworm. In July owing to the very hot weather we 

 had more trouble with grasshoppers and crickets than has been experienced in 

 this county for some years. Grasshoppers stripped considera])le vegetation but 

 largely confined their energy to cutting binder twine after the sheaves had 

 been tied. Many reports have l3een received in some instances where crickets 

 and grasshoppers had destroyed binder twine in wholesale quantities. Clover seed 

 midge was reported from a number of fields, but is not believed to be common 

 throughout the county. Hessian fly: some reports of injury during fall of 1918. 



Attacking Fruit Trees. Codling Moth very plentiful especially in uncared 

 for orchards ; considerable damage done in orchards that had not been sprayed, 

 about three broods reported in many instances.
