HoLLiSTER (W. 0.). Distribution of Shade Tree Insects in 1919. — 

 Jl. Econ. Entom., Concord, N.H., xiii, no. 1, February 1920, 

 pp. 143-146. [Received 13th April 1920.] 



The country east of the Mississippi and north of the Mason -Dixon 

 line is dealt with, but more especially that around the larger cities 

 from Chicago eastwards towards Boston and Washington. 



Aphids were abundant, especially PhyUapJtis fagi and Phenacoccus 

 acoicola. Of scale -insects the oyster scale {Lepidosaphes ulmi) was 

 numerous, others being Chionaspis pinifoliae, Tourney ella liriodendri, 

 Chionaspis americana, Gossyparia ulmi, Pidvinaria vilis , Asterolecanium 

 variolosum, and occasionally the San Jose scale [Aspidiotus 

 perniciosus]. 



Leaf-eating insects were not particularly destructive, except canker- 

 worms locally in the spring. Those reported include : — Melasoma 

 scripla (cottonwood leaf l^eetle), Vanessa an'iopa, Thyyidopteryx 

 ephemeiaejotmis, Datana integenima, the elm leaf beetle [Galerucella 

 luteola], the elm leaf-miner [KoliosyspJiinga ulmi], the elm case-bearer 

 {Coleopliora limosipennella), Hyphaniria cunea, which seems on the 

 increase, Chalepus dorsalis (locust leaf-miner) and Hemewcampa 

 leucostigma (tussock moth). 



The most destructive insects are the borers, their presence frequently 

 escaping notice till serious damage has been done, though they 

 seem to prefer trees of a lowered vitality. The bronze birch borer 

 {Agtilus anxius) is gradually kilhng white birches, and the hickory bark 

 borer. Scaly tus [Eccoptog aster) quadrispinosus, is also very destructive. 

 Others are S. {E .) mullistriatus, P rionoxystus robiniae,CyUene robiniae, 

 Ecdy'ohpha insificiana, the leopard moth {Zeuzera pyritia), the sugar 

 maple borer {Plagionotus speciosus), Aegeria (Sesia) acerni, Agrilus 

 hilineatus, and twig pruners, especially Elapliidion villosum. The 

 black carpenter ant {Camponotus) tunnels into and weakens a tree if 

 it finds an opening, while red spiders (Telranychus) are causing increas- 

 ing injury. 



Walton (W. R.). European Corn Borer in Broom Corn.— JL Econ. 

 Entom., Concord, N.H., xiii, no. 1, February 1920, p. 147. 

 [Received 13th April 1920.] 



Early in February 1920, considerable numbers of both larvae and 

 pupae of Pyrausta nubilalis were intercepted in broom corn 

 (Andropogon sorghum) by the Federal Horticultural Board. The 

 broom corn in question came from Venice, and consisted of 97 bales of 

 200 lb. each, an occurrence that strengthens the belief that this moth 

 first gained access to America in this grain. 



Wadley (F. M.) Note on Eriopyga incincta, Morr. — Jl. Econ. Entom., 

 Concord, N.H., xiii, no. 1, February 1920, p. 148. [Received 

 13th April 1920.] 



The cutworm-like caterpillar of Eriopyga incincta is recorded as 

 abundant but local in Kansas. Lucerne, and probably beans, were 

 attacked. The larvae were not observed actually feeding, but were 

 hidden on the surface of the ground,, at the same time that Feltia 

 subgothica, usually the commonest cutworm, was scarce.
