feeding on seedling cmcifers in frames, though it does not generally 

 attack farm crops. Larvae of Hepialits spp. are abundant on waste 

 places and among grass, and have been taken at the roots of rye grass 

 and clover in April. 



Natural enemies of these insects include two unidentified Hymenop- 

 terous parasites reared from Mayetiola {Cecidoniyia) destructor and 

 Agromyza nigripes. No parasites of wireworms were observed, though 

 carnivorous ground beetles, such as Pterosfichus (Steropus) madidus and 

 Nebria hrevicollis, apparently devour them, and larks and jackdaws 

 probably destroy large numbers.

In this further account of the biology of Agriotes [R.A.E., A, 

 viii, 137], descriptions are given of the egg of A. obscurns, L., and of 

 the early and late larval and also the pupal stages. In a subsequent 

 part, it is hoped to give some description of the larva of Agriotes 

 sputator, L., with notes on the early stages of A. sobrinus, Kies. 

 {acuminatus, Steph.) and Athous haemorrhoidalis, F.

The life-history of Philaenus lineatus, L. (grass-feeding frog-hopper) 

 is described from observations under wire cages in the field, the data 

 being given in the form of tables. The stages of the insect are 

 described and the habits of nymphs and adults discussed. The 

 remedial measures advocated by Osborn are recommended [R.A.E., 

 A, vi, 11].

Aspidiotus perniciosus (San Jose scale) was less abundant than 

 usual ; this was probably due to the severe winter weather rather 

 than to the activities of the parasite, Prospaltella perniciosi, Tower, 

 which has become less effective than formerly. The most serious 

 feature of the insect situation was the continued spread of Pyrausta 

 nubilalis, Hb., though injury attributed to this moth in some locaKties 

 was found to be due to Papaipema nebris, Gn. {nitela, Gn.). In the 

 spring and early summer, Conotrachelus nenuphar, Hbst., caused much 

 damage to plums and apples, and the red bugs, Heterocordylus malinus, 

 Rent., and Lygidea mendax. Rent., were serious pests, having gradually 

 increased in "numbers during the last five years. Macrodactylus sub- 

 spinosus, ¥., was unusually abundant on grapes, roses and other 

 plants. The increased number of vegetable gardens owing to the 

 War resulted in an abundance of Haltica spp. (flea-beetles), Diahrotica 

 vittata, F., Leptinotarsa decemlineata. Say, and Lema trilineata, 01. 

 Severe defoHation of beech, maple and other trees was caused by
