markings; thoracic sliield pale yellowish, with a dark brown, triangular 

 mark on the caudo-lateral margin on each side. Tlie thoracic shield is 

 divided by a narrow pale line, which is bounded on each side by a narrow 

 pale brown stripe which is considerably wider posteriorly. The whole 

 of the dorsum above the spiracles is very dark green in colour, with the 

 tubercles conspicuous, and of a dull yellowish white. Below the spiracles 

 the body is pale yellowish, with the tubercles of that region light in col- 

 f)ur and prominent. In the centre (if each tubercle there is a dark hidwn 

 circular spot, from the centre of which arises a single pale seta. The anal 

 plate is paler than the dorsum, and bears eight setae. There is a pro- 

 nounced anal fork beneath the posterior margin of the anal plate. The 

 thoracic legs are pale brown; prolegs eoncolorous with venter. Spira- 

 cles dark brown. 



The pupa is 12 to 15 mm. in length, very dark brown above, and 

 somewliat paler beneath. Pupation takes place within folded ajiple 

 leaves in the same manner as with the other leaf-rollers mentioned in 

 this paper. The pupae under observation spent from 12 to 15 days in 

 this stage. Adult emergence from pupae taken in the field covered a 

 pi'riiul of approximately two months. 



Peronea maximana B. & B. 



In Scientific Agriculture, March, 1921, wc find the first authentic 

 record of this insect as an orchard pest in the Okanagan Valley. In this 

 article, "Some notes on the fruit worms of British Columbia," by Mr. R. 

 ('. Trehei-ne, Dominion Entomological Branch, Ottawa, this insect is 

 included among the fruit worms of the province, and is remarked upon 

 as follows: "Peronea, (Alceris) maximana has jnoved an interesting 

 insect attacking orchard trees in the Okanagan Valley, not so much from 

 its economic importance, which is slight, but from its identity and dis- 

 covery. The early authors on British Columbia insects record the pre- 

 sence in the province of Teras minuta. Much of the work ascribed to the 

 bud moth, T. ocellana ;ind the lesser apple worm has been placed to the 

 credit of Teras minuta in the minds of field inspectors. Its presence is 

 poinilarly Ijelieved to exist, and doubtless some moths M'ere originally 

 identified as referable to this species. The writer has, however, been 

 unsuccessful in recovering Teras minuta, and all efforts to collect it or 

 its near relatives have failed, until this year, when Peronea maximana 

 was bred from the North Okanagan. Its identity was proved liy Dr. J. 

 ]\IcDunnough, Dominion Entomological Branch, Ottawa." 



The life-history of this insect has only been slightly studied, and 

 beyond the fact that larvae were taken on the terminal shoots of apple 

 during the early summer of 1920, and that moths developed from these 

 in August and September nothing is known. Mr. E. H. Blaekmore re 

 ports that the insect is more or less common on Vancouver Island, and 

 that in some seasons it is extremely common at Eraser Mills, in the lower
