were breeding enough to be troublesome. The species was 

 determined by Mr. Schwarz through the courtesy of the United 

 States Bureau of Entomology. 



Corticaria ferruginea Gyllenhal Lot 291. 



Dense swarms of these minute beetles occurred at Orono in 

 the early evening of July 13, 1908. At that time a forest fire 

 was raging west of Orono and the wind was from the west at 

 the time the beetles were taken. Whether the beetles were 

 escaping from the burning district or whether this circumstance 

 was merely a coincident was not ascertained. 



Brachys aerosa. 

 These Buprestid beetles (Lot 249) were common upon oak 

 the leaves of which they were eating in the vicinity of Portland 

 ]\Iay 25, 1908. The larvae are leaf miners. The beetles were 

 by no means so numerous as last season in the same localities, 

 as recorded on p. 270 of Bulletin No. 148 of this Station. 



Dendroctonus terebrans. 

 The Turpentine Bark Beetle, Lots 244 and 300, were abun- 

 dant at North Fryeburg, May 29, about windows and were 

 reported in numbers from East Denmark, July 14. 



Monohmmnus titillator'^ Lot 302. Sub. i. 



Monohammus sciitellatus Lot 302. 

 Two of these pine borers were received from Ross Corner, 

 July 17, with the comment "They had about stripped one side 

 of the tree" (a small white pine). Being in doubt as to whether 

 the stripped pine was the work of these beetles, as sawflies were 

 pretty generally numerous, the writer placed the beetles in a jar 

 with fresh pine twigs and they very soon began to chew along 

 and through the needles, strewing the bottom of the jar with the 

 needles which they had nipped through.
