of various pines. A key is also given to the Spanish species of Sign- 

 phora with notes on S. {Matritia) coitjugalis, Mercet, which is probably 

 parasitic upon some Coccid, like other members of the genus, and is 

 found on pines throughout the south and centre of Spain. S. (M.) 

 simillima, sp. n., taken on branches of Finns silvestris in July 1917 is 

 described.

Nearly the same results as already recorded [see this Review, Ser. A, 

 vii, p. 238] are given ; the author's view that Japan is the original 

 home of this fruit-fly {Dacus tsuneonis) is withdrawn.

The author further describes the morphology and life-history of, and 

 control measures for, the Japanese orange-fly {Dacus tsuneonis, Miysike). 

 Among the new data added are the fact that out of 1,000 pupae 

 buried under the soil about 67 per cent, emerged, the rest being found 

 to be dead. IVIoles prey extensively upon the pupae of this fly, so that 

 in this respect they should be looked upon as beneficial.

The authors agree with the ^transfer by Hampson of the moth, 

 Seudyra subflava, Moore, from the Agaristidae to the Acronvctinae. 

 The total life-cycle is not yet known. It is probably a two-brooded 

 insect. In Japan the caterpillars appear in May and June, the moths 

 in July, the caterpillars of the second generation in August, and the 

 moths in the following May. In Manchuria, the caterpillars appear 

 in June and July and the moths in August. This species attacks 

 the leaves of vine and ivy, and in Manchuria does no small damage in 

 vineyards, especially to young foliage.

The occurrence of the sawfly, Cryptocampus {Euura) laetus, Zadd., 

 is reported from Sweden, where a plantation of Salix viminalis (basket 

 willow) was seriously injured. The galls produced give rise to small 

 wounds in the rods, rendering them useless for the finer grades 

 of basket work and apt to be easily broken. The larva is described
