(anjollodcs mcla liner phal lift), tho larva of a tonobrionid hootio whic-li iiijuri's 

 wlieat and flaxseed, the Knuii borer (Chloridva obsolcUi) and the sugar cane 

 moth borer {ChUo nimiilv.r). 



The sugar cane grasshopper {Hieroglj/phus furcifer) ai)pears to be one- 

 brooded. " The eggs are laid in the ground in November about 2 in. below 

 the surface. Soon after the first rainfall at the end of June or early in July, 

 the young hoppers hatch out and begin to feed on young suger cane or millets, 

 preferring the more succulent millets in this stage. Later on they confine 

 their attack to sugar cane, probably on account of the protection which the 

 crop (usually 4 ft. high at this time) affords from predaceous birds. The 

 nymph molts about 5 times and matures by the middle of September. The 

 mature insect begins to lay eggs in November in the field in which they are 

 feeding, afterwards dying." 



Plowing in July and August, although late, did a certain amount of good in 

 checking the pest, the eggs exposed being quite mature and hatching out in 

 15 minutes after exposure. 



Report of the entomologist, W. W. Frog(jatt (Rpt. Dcpt. Agr. X. >S. Wales, 

 1909, PI). 32-3-)).— The work for the year ended June 30, 1909, is briefly 

 reported. 



Among the insect pests mentioned as having been of particular importance 

 are fruit flies, the tomato fly {Lonchcca spJcndkla), the flea beetle {Aisipoda 

 tnacleayi) which damaged young apples by eating the outer surface, the bean 

 fly, the larger plain locust (Chortoicetes terminifera) , the pumpkin beetle 

 (Aulacophora oUvieri) which attacked nectarine foliage and fruit and cherries, 

 as well as garden vegetables, and a species of thrips that injured wheat. An 

 insi^ection for the fowl tick of 428 domestic fowls consigned to Victoria, South 

 Australia, and West Australia is reported. 



The scarabee of the sweet potato, H. A. Ballou ( IFr.s/ Indian liiil.. 10 

 (1909), No. 2, pp. 180-196, figs. 10). — Cryptonjnchus batatfr, which attacks the 

 roots and the base of the vines whei-e they are thickened and woody in struc- 

 ture, is reported to be the source of considerable injury to the sweet potato in 

 Barbados, as much as one-third of the crop being lost on certain estates. 

 Laboratory and field experiments and remedial measures are reported. As yet 

 only general recommendations can be made. The rotation of crops in such a 

 way that sugar cane is always grown between the croi)s of potatoes is strongly 

 recommended. 



The sweet potato moth ( I'volopane cingiilatd) seems to prefer the sweet 

 potato, and a severe attack often results in the complete loss of the foliage over 

 entire fields, only the bare stripped vines being left. That severe attacks over 

 large areas occur only at intervals of several years appears to be due in a large 

 measure to natural enemies, particularly a tachinid (Stunnia diiitincta). Men- 

 tion is made of several other pests of sweet potatoes, including the red si)ider 

 (Tetmnj/chiis tclariiis) and thrips. 



Insects which attack vine buds, W. Wkslkv (Agr. Ha.:: V. N. Wales. 20 

 (1909), No. 9, p. HO.i). — Oitliorrhinn.s glindrirostris is re|)orted to attack buds of 

 the grapevine both before and after they have burst. As the season advances 

 the insects increase in numbers, eating the bark from young wood and destroy- 

 ing the young grapes. The apple and vine root borer (Lrptops iiopci), a similar 

 weevil, attacked the vine and apple buds in the Maitland district and was 

 checked chiefly by band ] licking. 



Trees attacked by Termes gestroi, H. \. Kidi.ky (Agr. Hal. SI rails and I'cd. 

 Malay Statfs. ,S (1909), No. 12, pp. 'j(!.1 56/,).— A list is given of the trees in 

 Johore attacked by this species of white aut.
