spp., etc. ; and P. viridicollis, Baudi, injures the foliage and epidermis 

 of the young growth of Fraxinus, Cytisus, Acer and Qiiercus cerris. 

 P. impressifrons (poplar root weevil) is found in Europe on Populus 

 spp., Salix, Alnus, etc. In New York and Connecticut it has caused 

 considerable damage to Salix, Pofulus, birch, apple and pear. 

 Adults appear during the latter part of May and oviposit immediately 

 under loose bark, among loose bud-scales or in wounds. The eggs are 

 laid in masses of from 20 to 80, and the larvae, upon hatching, drop to 

 the ground and feed on the roots of the host. The adults may be 

 controlled by the application of arsenicals. P. sericeus occurs in 

 Europe in the adult stage on the buds of pear, plum, beech, hawthorn, 

 apple, etc. In America, it has been recorded from Indiana. 



Notes are given on the feeding habits of 35 additional species of 

 Polydrusus, occurring mainly in Europe. 



Jones (T. H.). Notes on Anasa andresii, Gu6r., an Enemy of 

 Cucurbits. — Jl. Econ. Entom., Concord, ix, no. 4, August 1916, 

 pp. 431-434. 



Anasa andresii, Guer., has been recorded from Cuba, Mexico, 

 Guatemala, Costa Rica, Panama, Colombia, and in the United States 

 from Florida, Texas, and New Mexico. The notes on the life-history 

 given in this paper were obtained during 1915 from a study of this 

 species on squashes in Louisiana. The first adults were observed in the 

 field on 26th May. Eggs were found soon afterwards, usually on the 

 under surface of the leaves, occasionally on the upper surface or on 

 other aerial portions of the plant, or on surrounding vegetation. 

 They are placed singly or in masses containing from 2 to 50 eggs. 

 The incubation period varies from 7 to 11 days between June and 

 September inclusive. Nymphs and adults feed on the juices of the 

 leaves, causing them to wilt and die. The duration of the nymphal 

 stage is about 18 days. 



Hyslop (J. A.). Triphleps insidiosus as the Probable Transmittor of 

 Corn-Ear Rot {Diplodia sp., Fusarium sp.). — JL Econ. Entom., 

 Concord, ix, no. 4, August 1916, pp. 435-438. 



Previous records of the Anthocorid bug, Triphleps insidiosus, have 

 shown that it is both beneficial, in that it attacks various stages of 

 Blissus leucoptera, Phylloxera, Chloridea (Heliothis) obsolela, Contarinia 

 (Diplosis) sorghicola, etc., and injurious, in that it causes injury to 

 chrysanthemums, squash vines and red clover. Corn-ear rot, due to 

 Diplodia sp. and Fusarium sp., was observed in the maize crops in 

 Maine in 1912. The disease appeared when the seeds were in the milk 

 stage as a yellowish discoloration immediately below the point of attach- 

 ment of the silk. From this point the discoloration spread throughout 

 the seed, until finally the seed-coat ruptured. Experiments on the 

 transmission of the disease showed that the fungus could only enter 

 through a puncture in the seed coat. Large numbers of T. insidiosus 

 were found to be present in infested fields in the silk, under the husks 

 and among the dead leaves, etc., at the base of the plants. It was 

 therefore considered probable that this insect was connected with the
