Nemoriva leucaiiia: [ Winthemia ^-pustiilata']. When and where the eggs 

 are laid and other items of life-history. 



[Extended in pages 190-214 of this Report (xii).] 



Snapping Bugs. (Country Gentleman, for August 6, 1896, Ixi, p. 610, c. 

 I — 12 cm.) 



In response to an inquiry from Beaver Creek, Col., it is stated, that 

 it has been found serviceable to attract click-beetles, or snapping-bugs 

 to poisoned baits, from May to August inclusive. The exact time for 

 •continuance of the baits to be ascertained by the number of beetles 

 <h-awn to them. Freshly cut clover, dipped in Paris green water, is 

 perhaps, the best bait. A corn or bran mash sweetened with sugar 

 and containing arsenic should be effective. 



Blister Beetles. (Country Gentleman, for August 13, 1896, Ixi, p. 624, 

 c. 3 — 12 cm.) 



Insects sent from Madison, N. J., where they had been feeding on 

 beets and mangels, are of two species. The black one, with a narrow 

 ash colored margin on the wing covers, is the '-margined blister 

 beetle," Epicauta cinerea (Forst.), a common and destructive species 

 at times, feeding on potato and tomato leaves ; seldom continuing 

 longer than a week. The other, "the striped blister-beetle," Epicaida 

 v'lttata (Fabr.), is especially destructive to potatoes and is a more 

 southern form. Lime or plaster of Paris are remedies. The larvse of 

 these beetles, destroy grasshopper eggs and are therefore beneficial. 



Willow Butterfly. (Country Gentleman, for August 27, 1896, Ixi, p. 666, 

 cols. I, 2 — ID cm.) 



Caterpillars, identified as Vanessa A?iiiopa, are stated to have rav- 

 age'! trees on the bar [at Whitehall, N. Y.], next the Lake, to an 

 extent that caused them to look as if dead. Their occurrence in such 

 desti active numbers is quite unusual. 



Caterpillars and Parasites. (Country Gentleman, for August 27, 1896, 

 Ixi, p. 670, cols. I, 2 — 21 cm.) 



A half-grown larva of Ampelophaga Myron (Cramer), from a wood- 

 bine at Port Kent, N. Y., is nearly covered with the cocoons of its 

 common parasite, Apanteles congregatus. The history of the parasite 

 is given, and also of a secondary parasitic attack by a Chalcid on 

 Apanteles. 



The Oak Pruner. (Country Gentleman, for September 3, 1896, Ixi, p. 

 682, c. 4 — 6 cm.) 



The small limbs of some hard maple trees at Baltimore, Md., are 

 cut off by some insect, as clean, as though with a knife. The attack is 

 identified, as, in all probability, that of the oak pruner, Elaphidion 

 parallelum Newm. The insect may be kept in check by collecting 

 the fallen branches and burning them.
