Macdougall (R. S.). Insect and Arachnid Pests of 1920. — Separate 

 from Trans. Highland & Ai^ric. Soc, Scotland, 1921, 38 pp. 

 18 figs. [Received 24th May" 1922.] 



The insects recorded are : Saperda carcharias, L. (large poplar 

 longicorn) [R.A.E., A, ix, 171] ; Hylesinusfraxini, ¥., and H. crcnatiis, 

 F., on ash ; Piiyogenes chalcographits, L., chiefly on spruce [Picea 

 excelsa), the differentiating characters of the adults and brood galleries 

 of this species and of P. bidentatus being described ; and various gall- 

 producing Cecidomyiids, including Rhahdophaga saliciperda, Duf., on 

 willow, which may be controlled by cutting and burning infested 

 shoots before the issue of the brood, and covering the attacked places 

 with tar so as to entangle the emerging adults. 



The ermine moths, Hyponomeuta padellus, L., H. malinelliis, Z., 

 and especially //. padi, Z. {euonymellits, L.), are destructive to fruit 

 and other trees, and a brief account is given of the hfe-history of the 

 latter. 



Other pests recorded are Hylemyia coarctata, Fall, (wheat bulb fly), 

 Sitona lineata, L. (pea and bean weevil), and Ceuthorrhynchits pleiiro- 

 stigma (turnip gall weevil). 



A brief account is also given of the life-history of, and damage caused 

 by Anohium striatum, 01., in pine and spruce wood, etc. ; Sitodrepa 

 panicea, L. [R.A.E., A, vi, 160] ; Ptilimis pedinicornis, L. ; Xestobium 

 ritfovillosum, DeG. {iesselatnm, 01.) ; and Lyctus brunnetis, Steph., and 

 L. linearis, Goeze [canaliadatus, F.). Various ways of treating and 

 protecting furniture against the attack of these beetles are quoted.

— Agric. Gaz. N.S.W., Sydney, xxxiii, pt. 4, 1st April 1922, 

 pp. 253-259, 12 figs. 



This is an annotated list of species occurring during 1916-18 in 

 stored wheat, together with a brief reference to the part played by 

 each in the destruction of the grain. The species causing most damage 

 were Rhizopertha dominica, F., Calandra oryzae, L., and Tribolium 

 ferriiginenm, F.

XXV, no. 4, 15th April 1922, p. 290. 



Scales, identified as Aspidiotus perniciosus, Comst. (San Jose scale) 



and traced to a garden at Pelotas, were found on peach twigs received 



from the State of Rio Grande do Sul, this being the second record 



of infestation from that source. Immediate measures were taken 



to prevent any further dissemination of infested material to other 



localities.

 Loxostege sticticalis on Sugar-beet in Lower Austria.] — Mitt. 

 Bundesanst. f. Pflanzenschutz , Vienna, 1921, 7 pp. [Received 

 24th May 1922.] 



At the end of June 1921 the beet webworm, Loxostege {Phlyctaenodes) 

 sticticalis, L., began ravaging the sugar-beet fields in many districts 

 of Lower Austria, this being the first occasion that such an outbreak 

 has occurred there. Two generations probably occur in this region.
