Macrodadylus subspinosus (rose beetle) is recorded as damaging 

 peach, grapes, maize and rose, and in one instance the poisoning of 

 poultry as a result of eating the beetles is reported. Creosote barriers, 

 as recommended by Flint, and sprays [R.A.E., A, x, 197] were used 

 with success against the chinch bug [Blissus leucoptems]. The blister 

 beetles, Epicaiita vittata, E. cinerea, E. marginata, E. pennsylvanica 

 and Macrobasis unicolor were abundant on potatoes, tomatos and 

 other garden crops. This is apparently a logical sequence of the 

 grasshopper outbreaks of recent years. Lachnosterna sp. was most 

 abundant on maize and strawberries. 



Lucerne was injured during the latter part of September by Loxostege 

 sticticalis (alfalfa webworm) and Laphygma fnigiperda (fall army 

 worm), the latter occurring also on clover. Heliothis {Chloridea) 

 obsoleta (corn-ear worm) was abundant throughout the State, both on 

 field and sweet maize, as well as many other plants. Alabama argillacea 

 (cotton caterpillar) occurred in isolated sections on apple, and was 

 particularly injurious to strawberries in the northern part of the State. 

 Other pests recorded are Aegeria (Sanninoidea) exitiosa (peach-tree 

 borer), Mayetiola (Phytophaga) destructor (Hessian fly), codling moth 

 [Cydia pomonella], and fruit-tree bark-beetle [Scolytus riigulosus]. 

 As a result of experiments with various dormant sprays now on the 

 market for use against Aspidiotus perniciosiis, dry lime-sulphur is not 

 recommended unless liquid or miscible oil is not available, when it 

 should be used at lJ-2 times the strength usually recommended. 



Herrick (G. W.). The Maple Case-bearer, Parademensia acerifoliella, 

 Fitch. — //. Econ. Ent., Geneva, N.Y., xv, no. 4, August 1922 

 pp. 282-288, 5 figs. 



The Tineid, Parademensia acerifoliella, Fitch, has become so abun- 

 dant in New York State during the last three years that the sugar 

 maples in many groves are threatened with destruction. Its previous 

 history and synonymy are reviewed. It is apparently widely distri- 

 buted over the north-eastern United States and southern Canada. 

 Although the author has only found it on sugar maple, it has been 

 reared to maturity on red maple {Acer riibntm), and Fletcher records it 

 as feeding on the leaves of beech trees growing among infested maples 

 that had been defoliated. 



In breeding-cages the moths emerged from 11th to 23rd May. 

 In New York State they were found in abundance on 30th May 

 1922, and had already laid eggs. These are deposited in minute pear- 

 shaped pockets in the tissues of tlie leaves just below the lower epi- 

 dermis ; they hatch in about a week, the larvae bemg found in large 

 numbers by the 16th June ready to leave their mines. As soon as the 

 larvae hatch they mine in the tissues of the leaf, in which they live 

 about 10 days. The mines are mostly irregular, becoming somewhat 

 enlarged towards the terminus. In six leaves examined the number 

 of mines varied from 24 to 116. On completing its growth towards 

 the end of the summer the larva cuts an oval case out of the mine. 

 Pupation probably occurs about October. The pupae remain among 

 the fallen foliage until the following spring, there being but one 

 generation a year. 



Raking the fallen leaves into heaps and burning them would most 

 likely prove an effective check, the only other feasible method being 

 thorough dusting with lead arsenate by means of an aeroplane.
