cane grubs. The species dealt with inckide the wasps, Campsomeris 

 tasmaniensis, Sauss., and C. radula, ¥., which are known to attack 

 6 species of cane beetles with a preference for Lepidiota albohitia, 

 Waterh., and L. frenchi, Blackb. ; robber-flies such as Asiliis sp. ; 

 the Elaterid, Agrypnns mastersi, MacL. ; and Dexiid flies.

 Jl, Brisbane, xii, no. 6, December 1919, pp. 304-305. 



Attention is drawn to the increasing abundance of the sugar-cane 

 beetle borer [Rhabdocnemis obscura] in certain locaUties, and the 

 importance of burning all trash throughout the infested area and 

 planting clean seed is insisted upon.

 (Second Series.) — Queensland Bur. Sugar Expt. Sfa., Div. Entom., 

 Brisbane,^\x\\. 8, 1919, 51 pp., 1 plate. 



This bulletin gathers together the various monthly notes on sugar- 

 cane pests in Queensland from July 1918 to May 1919 which have been 

 published and noticed elsewhere [R.A.E., A, vi, 526 ; vii, 80, 109, 167, 

 200, 295, 411]. 



Froggatt (W. W.). The Peach Tip Moth {Laspeyresia molesia, Busck). 

 — Agric. Gaz. N.S.W., Sydney, xxx, no. 12, December 1919, 

 pp. 891-^92. 



Cydia (Laspeyresia) molesia, Busck, is now reported from Austraha, 

 where it causes severe damage to peaches. It appears to have been 

 present since 1909, and it has only now been definitely identified, 

 though its occurrence was recorded in 1914 [R.A.E., A, ii, 493]. 



The larvae were found at work towards the end of October, but by 

 the 18th of November neither larvae or pupae could be found in the 

 damaged twigs. Bandaging as for codling moth \Cydia pomonella] 

 proved the only successful remedial measure. On the 16th December 

 the bandages contained larvae and pupae. 



The moths were found attacking the peach tips in the early part 

 of January. Pupae were found under the bandages on 3rd February, 

 from which a parasite, Gambrus sfokesi, which also attacks C. pomonelkt, 

 was bred. 



Allen (W. J.). The Utility of the Spray Gun. —Agric. Gaz. N.S.W., 

 Sydney, xxx, no. 12, December 1919, pp. 893-894. 



The utility of the spray gun is compared with that of an angle nozzle 

 on a rod ; the latter proved the more satisfactory apparatus, as the 

 work done by the spray gun proved faulty near the tops of 11 to 12 

 foot trees. The spray gun is also unsuitable for the application of 

 caustic sprays in anything but very calm weather and cannot bo used 

 to spray downwards on to the tops of trees.
