Proteopteryx oregonana (early aspen-leaf curler) was one of the three 

 IVIicrolepidoptera that infested aspen poplar {Po]iulus tremuloides) in 

 1917-18 [R.A.E., A, vii, 73]. The moths are on the wing in swarms 

 in March. The larvae usually hatch towards the end of April, and 

 drop from the trees to pupate about the end of May. The pupal stage 

 lasts from early June till the following spring. 



Parasites of P. oregonana are numerous, but have not been studied. 

 Of predaceous enemies there are a number, particularly a Carabid 

 beetle, Calosoma frigidum, the adults of which devour the caterpillars 

 on the trees, while the larvae seek out and destroy the pupae buried 

 under dead leaves. Several birds also feed on the caterpillars, species 

 that are passing during migration being the more useful, as the cater- 

 pillars have pupated before many of the native birds commence to nest.

Pissodes terminalis, sp. n., here described, seems to be the only 

 Californian species of this genus to breed on lodge-pole pine {Pinus 

 contorta), and the only one to attack the terminals. In certain dis- 

 tricts large areas of lodge -pole pine stands have suffered seriously 

 from its attacks, the general infestation being on the terminal of the 

 stem. 



Many of the trees that had been attacked for three years had a 

 squat appearance, caused by curtailing height and stimulating lateral 

 growth. Healthy trees were attacked, while trees infected by the 

 fungus, Peridermium harknessi, were avoided. The terminal is generally 

 killed down to, and sometimes including, the first whorl of branches. 

 The larvae mine the centre of pith of the terminal, each terminal 

 producing from one to six weevils. Transformation takes place in the 

 autumn, the adult apparently hibernating through the winter in the 

 larval gallery. In many places the larvae were heavily parasitised 

 by a small Dipteron.

Panscopus {Phymatimis) sulcirostris. Pierce, is here recorded from 

 Vancouver Island. Large numbers of this weevil were found in early 

 May 1916 feeding upon the leaves of Lilium pardalinum ; and quantities 

 of the larvae, and a few pupae were disclosed by digging about the 

 roots of the lilies. There is every likelihood that this weevil may 

 reappear as a pest of some importance in flower gardens along the north 

 Pacific coast.

 This paper records an infection of " Big-bud " on Ribes bracteosum, 

 a wild black currant, by mites from infested black currant bushes 

 imported from England to Vancouver Island. On the mainland the 

 native hazel (Corylus calif ornica) is frequently attacked by a similar 

 mite, which also attacks Ribes lacustre aiid R. bracteosum.
