364 MAINE AGRICULTURAL EXPERIMENT STATION. 1908. 



Canthophorus cinctus Lot 392. 

 August 26, great masses of the red and black nymphs, in 

 several stages and the black and white adults of these bugs were 

 found congregated under chips and bits of rubbish. This 

 seems to be the hibernating habit of this species as such masses 

 are frequently met with late in the fall. 



Anasa tristis. 

 Squash bug. Strangely enough, the specimens sent from 

 Gorham, Maine, July 14, 1908, were the only specimens of these 

 squash bugs received by this Station in 5 years. 



Lygus pratensis. 

 The tarnished plant bug, Lot 308, was present among blacken- 

 ing and withering tips of potato vines at Waldoboro, July 20 

 where it was reported to be "working quite extensively in potato 

 fields." 



Podisus modestus. 

 Surely this species of soldier bug deserves honorable mention 

 as it was busily engaged in stabbing destructive caterpillars dur- 

 ing the entire season, over all parts of the State. 



Aphididae. 

 The plant louse collections have been more than 100 this sum- 

 mer and the material has been of considerable interest including 

 some new species as well as unrecorded forms of named species. 

 The dry warm season has proven a favorable condition for 

 aphid life and the weather was particularly good late in Sep- 

 tember and October when the true sexes are to be found. As 

 is to be expected, parasitic and predaceous enemies of the aphids 

 were abundant and many infestations were controlled by such 

 natural enemies. 



Nematus erichsonii and Other Sawflies. 

 Larvae of the Larch Sawfly, Lot 383, were taken at West 

 Houlton, July 7, 1908. Sawflies of many species seemed espe- 

 cially common upon the wing this season, and a considerable 

 number of undetermined species were collected.
