mor is recoinineiided, or early cuttins,' of the crop before the larv.ne of 

 the first brood liave matured and dropped from the seeds to the i;'rouiid

The clover-hay worm is found only in dry clover hay, the eggs being 

 dei)Osited in June and the larva* feeding througliout the rest of the 

 year, and changing into moths the following spring. Clean mowing is 

 advised and never storing clover hay 2 seasons in the same mow. 

 Where hay is attacked, bisulphid of carbon may be ajiplied, 3 or 4 lbs. 

 to each ton, and the hay covered with heavy blankets for a few days. 



Insects that are common hut not destructive (pp. 58-G4). — This i)art of 

 the bulletin comprises illustrated descriptive, life history, and remedial 

 notes ou the following insects: Clover-root mealy bug {Bactylopius 

 trifolii), clover-stem borer {Langurla mozardi), common yellow butter- 

 fly {Colias philodice), clover drasteria {Drasteria crcchtea), clover-head

The scale insect of mulberry trees, C. Sasaki {College of Afjr., 

 Tolyo, Japan, BuL, vol. 2, JSfo. 3, pp. 107-121, pis. 2). — Illustrated descrip- 

 tive and life-history notes on a scale insect of importance to the silk 

 industry in the East, and Mdiich is technically described as a new 

 species {Diaspis patelUformis). 



The male is orange red, with yellow appendages, and 0.8 mm. long by 

 0.25 mm. broad. The wing expanse is 2 ram. The female is oval, light 

 yellow, and possesses 9 segments, the third to the ninth being mar- 

 gined with a number of minute fine spines, simple or branched. There 

 arc two broods, the adults appearing in June and October, and the 

 males dying soon afterwards, while the females of the second brood live 

 through the winter on the mulberry bark. The larva* in the first two 

 stages of growth are oval, flat, and yellow, with 2 black eyes. At first 

 they are very active, but after the second molt they become fixed to 

 the bark and change into pupse. 



The species is found over nearly sdl of Japan, where it attacks chiefly 

 the mulberry, but also some other trees, the branches frequently being 

 corai)letely covered with scales and the trees greatly injured. A crude 

 method of treatment is to scrape oft" the scales from the bark, but 

 spraying with limewater, kerosene emulsion, or a mixture of water, 

 fish oil, and bicarbonate of soda, is recommended. A Chalcid and a 

 Coccinellid prey upon the scale. 



Some insects injurious to shade trees, J. B. Smith [New Jersey 

 Stas. Bill. 103, pp. 15,Ji{/s.4). — Descriptive life history and remedial 

 notes on the elm-leaf beetle {Galernca xanthomekvna), wood leopard 

 moth or imported elm borer [Zeuzera^ pyrina), and the white-marked 

 tussock moth ( Oryyia leucostignia). Spraying with London purple, Paris 

 green or arsenate of lead is recommended for the elm leaf beetle, an 

 apiilication to be made when the beetles are first noticed, a second when 

 the larvai begin to hatch, and a third 10 days later. The only remedy
