INSECT NOTES. 363 



Cryptorhynchus lapathi. 

 The Poplar and Willow Borer. Lot 327. This insect which 

 has been a serious pest in other states was observed on the 

 campus for the first time in 1907, a single specimen being taken 

 from a willow hedge, June 7. This season from the same hedge 

 these beetles were taken in several collections. On August 10 

 the females were observed chiefly upon new growth and some 

 were found with beaks buried in the bark. At this date also 

 they were mating. 



Conotrachelus nenuphar. 

 Plum Curculio as an Apple Pest. One of the most serious 

 apple pests in the State is the plum curculio. Besides the young 

 apples which fall in quantities and in which the weevils develop, 

 the fruit remaining upon the trees is so often and so generally 

 deformed that it is seriously injured. As is the custom of the 

 Station in regard to orchard pests, a circular of information 

 concerning the work and remedies for this insect is used for full 

 reply to questions about injuries due to the curculio. 



Aphrophora parallella. 

 The Parallel Spittle-Insect, Lots 319 and 326. In June, 

 deposits of white froth were observed generally upon the white 

 pines of the State and the young insects found in the froth were 

 frequently received with the question "are these the cause of 

 the 'pine blight?' " The full grown insects were abundant on 

 the white pine in the vicinity of Sebago Lake late in July, and 

 the specimens were determined by Mr. Heidemann through the 

 courtesy of the Bureau of Entomology, Washington, D. C. 



Briopeltis festucae. 

 The Cottony grass-scale was present as usual which means 

 parasited as usual. It could be found in localities where it has 

 been observed previous seasons but there were .no complaints 

 of serious injury to meadows. 



Leptoterna dolobrata. 

 This meadow insect could be swept up by hundreds in the net 

 about June 30 in the Orono grass lands. They exhibited great 

 variation both in color and in length of wins: covers.
