are promptly infested and destroyed, usually before the 

 blossoms expand. 



In regard to the service-berry moth (Argyresthia conjugella 

 Zeller), Mr. Quaintance said he had no difficulty in finding 

 larvae of this species in considerable numbers in apples in 

 orchards on Orcas Island. The larvae at this time (late 

 August) were mostly full grown and occurred in the blossom 

 end of apples, feeding in a cavity there excavated, while many 

 individuals had penetrated to the seeds, which had been more 

 or less hollowed out. The larva very much resembles the lesser 

 apple worm (Enarmonia prunivora Walsh) and might readily 

 be mistaken for it. In one orchard examined, approximately 

 75 per cent of the fruit was infested. In others investigated 

 farther back from the shore-line, and which had evidently been 

 sprayed, the injury was much less. 



Mr. Quaintance also called attention to a recent account of 

 the service-berry moth by Professor Sven Lampa, and exhibited 

 a translation of this paper which Mr. C. B. Hardenberg had 

 kindly prepared for him. It was not thought that this service- 

 berry moth would prove to be especially important in orchards 

 regularly sprayed for the codling moth, since its habit of feed- 

 ing within the calyx cavity in a way very similar to the codling 

 moth would render effective arsenical treatments. 



It was found, during the course of a day's examination of 

 apple orchards in the Orcas Island region, that the codling 

 moth had not yet reached that territory. 



Attention was called to an investigation in progress, in north- 

 ern Ohio, of two barkbeetles, Scolytus riigulosus Ratz. and 

 Phlceotribus liminaris Harris, which have become unusually 

 abundant, infesting principally the peach, but also attacking 

 other deciduous fruit trees. This work was undertaken in 

 cooperation with the Ohio agricultural experiment station, and 

 Mr. H. F. Wilson, working for the Bureau of Entomology, 

 spent the entire season in the field, with headquarters at Lake- 

 side, Ohio. Considerable time was being devoted by Mr. Wil- 

 son to life-history studies of the two species, and extensive 

 tests of various tree washes and other remedial operations 

 were in progress. Photographs were shown of an orchard
