February. The main stem of the vine is ringed, but only a few 

 mulberry plants per acre are affected [cf. R.A.E., A, viii, 100]. 

 Trachvs hicolor is widely distributed as a pest of Butca frondosa 

 \R.A.E., A, viii, 514]. 



Young sugar-cane in sandy soil was considerably damaged from 

 July to September 1920 by larvae of a sugar-cane root grub. In 

 October 1915 a Dynastid was found damaging the roots of paddy. 

 The adults were able to remain under water for some time. An 

 occasional serious pest of grape vines is Scelodonta strigicollis, Mots., 

 a Eumolpid beetle which feeds on the leaves and scrapes the surface 

 of immature canes and shoots in patches. It does not occur on 

 vines trained in the local way, but was a serious pest in a 

 vineyard trained in the European manner. It was controlled by 

 collecting the adult beetles by means of a box 3 ft. square with the 

 inside tarred.

 Res., London, xii, pt. 3, November 1921, pp. 211-220, 7 figs. 



The new species described are Pinnaspis simplex and Fiorinia 

 chinensis, on undetermined food-plants from China ; Lepidosaphes 

 tubulorum, on Sapitim sehifenim and Salix laarburgi in Formosa, and 

 on Ilex crenata, willow and currant in Japan ; and Pygalataspis 

 miscanthi, gen. et sp. n., on a grass, Miscanthus sinensis, in Formosa. 



The opportunity is taken to rectify certain errors in the identification 

 of a few species from Japan. The collections examined indicate that 

 the Coccid fauna of Formosa is more closely related to that of Southern 

 Asia than to that of Japan.

—Bull. Ent. Res., London, xii, pt. 3, November 1921, pp. 221- 

 232, 17 figs. 



Several species of Bibionids occur in large numbers in the spring 

 and early summer in Britain, and their larvae are at times reported 

 to have damaged various crops. The life-history of Bibio johannis, L., 

 has previously been dealt with [R.A.E., A, vi, 118]. The present 

 paper gives an account of B. marci, L., B. ladeipennis, Zett., and 

 B. venosns, Mg. Very few parasites of Bibionids are known. In 

 addition to those mentioned by other authors, a Gregarine (probably 

 Schneideria mucronata, Leger, recorded by Keilin) was found in a 

 larva of Dilophus febrilis, while another, probably the Glugea also 

 mentioned by Keilin, was taken from a larva of B. johannis. A 

 Phorid, Hypocera incrassata, Mg., emerged from a mature larva of 

 B. marci, only a single parasite being observed in each individual 

 attacked.

The damage done by Agrilus foveicollis. Mars., to rose trees in 

 Bulgaria, especially Rosa damascena, Mill., which is extensively grown 

 for making attar of roses, is described, and the known facts about
