tive to young chestnut trees at Stamford. The New York weevil {Ithyccrus 

 noicboracensis) injured young jiear trees in one locality by eating out the base 

 of the new growth. Other inse<"ts noted as a source of injury are Otiorlnjnchus 

 sulcatus by eating the leaves of palms, lemon trees, etc., the strawberry weevil 

 {Anthonomus signatus), the raspberry sawfly (Monophadnoides ruhi), apple 

 leaf-folder (Ancylus nubeciilaua). the leopard moth {Zeuzcra pi/rina), the boll 

 worm, and the pyramid caterpillar { I'l/njiJfiUa iiyramidoidca). 



Insect notes for 1908. Edith M. Patch (Maine Sta. Btil. J 62, pp. 351-368, 

 pis. !l). — This bulletin contains brief accounts of the more important insects 

 of the year IDOS. 



Nymphs of a predaceous bug, probably Podisus inodestus, are reported as 

 occurring in the uests and feeding upon young, brown-tail moth caterpillars. 

 The greatest amount of damage caused by any single sr)ecies was due to 

 Jfrtcrocampa guttivitta. Associated with H. guttivitta were the rosy-striped 

 oak-worm (Auisota virginiciisis [pcUucida]) and the green-striped maple-worm 

 (.-1. [Dryocampa] ruhicunda), the former particularly on oak and the lat- 

 ter upon maiile. The white tipped moth ( Symmcrista [Edema] alhifrons) was 

 very prominent on oak, birch, and other trees. Argyroploce abictana injured 

 spruce in one locality by eating out the inside of the leaves. Acrobasis (Phycis) 

 rubrifasciclla was injurious to sweet fern and white birch. Galium verum 

 was found to be a much preferred food plant of Deilephila galli which also 

 feeds upon fireweed, strawberry leaves, etc. Datana major was numerous upon 

 deerberry, while gall mites (Eriopltyes fraxiniphila and E. fraxini) are said 

 ta have attacked red ash in the vicinity of Orono. Other insects reported 

 include the beau worm (Ogdocontu cinrrcola), Alcothoe caudata on the blos- 

 soms of Virgin's bower, Estigmcnc acrcea, Diucrisia (Spilosoma) virginica, 

 Basilona impcrialis, the pine hawk moth (Jjupara bombycoides), Dibolia bure- 

 aus, the raspberry cane borer (Oberea bimaeulata), Osmoderma scabra, Der- 

 mestes vulpinus in tankage and curd from dried buttermilk, Corticaria fer- 

 ruginea, Braehys cerosa, Dendroctonus terebrans, llonohammiis titillator and 

 M. seutellatiix, Cryptorhynchus lapathi, Conotraehelus nenuphar, Aphrophora 

 parallcUa, Eriopeliis festucw, Lcptoierna dolobrata. CanthoyliorutS einetus, 

 Anasa tristis, Lygus praten.sis, Xcmatus erichsonii, Lophyrux abietis, plant 

 lice and several si»ecies of grasshoppers. Tiphia inornata, a parasite upon the 

 white grul), was very numt>r<ius. 



The apple leaf -hopper and other injurious insects of 1907 and 1908, F. L. 

 Washbi-rn [Minnesota Sta. Bui. 112, pp. lJi5-25-'i, pi. 1, figs. 67).— Studies 

 made of Empoasea mali have shown it to be at least two-brooded in Minnesota. 

 The eggs of the summer brood are deposited in the petiole of the clover, apple, 

 and i)robably other j)lants. There are said to be 5 nymphal stages, a period of 

 22 days elapsing after hatching before the adults ai)pear. Adults live 14 days 

 or longer. The presence of the winter egg is denoted by a blister-like swelling 

 on the bark of the apple. The itest does not seriously injure orcbard trees 

 but retards the growth of nursery stock and also occurs on a large nunilx'r of 

 other plants, including alfalfa. It appears desirable that nursery stock be 

 grown at some distance from the apple orchard. The best results as regards 

 reuKtlial measures have been obtained from the use of screens smeared with 

 tangle-foot. Fish-oil soap 1 lb. to 10 gal. of water was found to kill adults 

 and young if they were I'.ot too well protected by the curled leaves. Among the 

 destructive shade-tree pests briefly considered are the oak pruner ( Elapfiidion 

 rillosum), .lOgeriid ash borer (I'odesesin [.Egeria] frajini), stalk borer (Pa- 

 paipema furrata), locust borer (CylUne robinia-), box elder mai»le borer, bronze 

 birch borer (Agrilus anxius), white pine louse (Chrrmes pinicortis), alder 

 aphis {Pemphigus tesselatus), cottony maple scale, fall webworm, poplar leaf
