by Hyponomeuta padellus and H. euonymellus occurred. The attacks 

 of Galerucella (Galeruca) lineola on the alder forests in Vestlandet, 

 which began in 1912, continued in 1913 with, if possible, still 

 greater severity ; frequently the trees were killed, which was a 

 serious loss, as in many places this is the only kind of tree which 

 grows on the slopes of the fjords and their leaves are largely used as 

 forage, Melasonia (Lina) aeneum occurred together with G. luleola 

 and, at Telemarken, it seemed to outnumber it. Cladius vwiinalis 

 was reported from Ingdalem, where the larvae in two years defoliated 

 some big balsam poplars. The following Aphids were recorded :■ — 

 Telraneura ulmi on elm, Lachnns fagi on beech trees, FhyUoxera quercus 

 on oak, Aphis avenae on bird cherry, Phyllopsis fraxini on ash and 

 PsylJd alni on alder, Hylolrupes bojulws for many years has done great 

 damage to timber in houses, and another Cerambycid, CaUidium 

 violaceum, appeared in great numbers in several houses, having in all 

 instances been brought in with the timber. Anobium striatum occurred 

 in furniture, both new and old. and A. pertinax was recorded in the 

 timber of an old house ; Formica herculeana also damaged timber in 

 a house.

 Argyresthia iUumitiatella has hitherto only been recorded from 

 Germany, where it sometimes injures the fir plantations, and is evidently 

 common in Sweden, although it is now recorded as a pest in that country 

 for the first time. The larva attacks the young buds and hibernates 

 in them ; pupation takes place in May of the following year and the 

 moths appear in the latter half of June ; only one generation occurs 

 in the year. When the terminal buds of young trees are attacked, 

 their development is arrested, but the lateral buds usually develop 

 normally. A very characteristic feature of the damage is the narrow, 

 spirally twisted gallery in the axis of the bud, which the larva excavates 

 previous to entering the terminal bud. When, on the other hand, the 

 small buds on the lower branches of older trees are attacked, not only 

 the terminal and lateral buds are completely excavated, but also part 

 of the axis. At the end of the excavated part of the axis is a circular 

 hole made by the larva when it has finished feeding and before it 

 returns to the bud in order to pupate.^, illiuninatella has already been 

 recorded from several localities in Sweden. It occurs commonly in 

 the neighbourhood of Stockholm and has been reported from Vaster- 

 norrland and from Stromsund in Jilmtland, where from 25 to 50 

 per cent, of the young trees were attacked.
