from 90 to 95 per cent of all of the mature lodgepole pine and 

 most of the yellow pine. It does not attack the young lodge- 

 pole pine but kills many of the young yellow pines. Nearly 

 all of the remaining live lodgepole trees were attacked this 

 summer in August and July, and by next year will be dead. 

 The beetles enter the living bark of the trunk in July and 

 August, and lay their eggs there. The eggs soon hatch and 

 the larvae feed in the bark until winter, and hibernate there in 

 the large larval stage. They pupate and change to adults in 

 the spring, and emerge during July and August, to attack 

 fresh trees. 



The destroyed area is brown, and looks as though scorched 

 by fire. From it the beetles are scattering to other parts of the 

 forest, and dead patches can be seen for miles around. 



From a forester's standpoint, the conditions may not seem so 

 bad, as there is a fine new growth coming up amongst the dead 

 trees. But if a fire should get into the dead timber, which 

 is very likely to happen unless carefully guarded against, this 

 new growth would be destroyed and the ruin would be 

 complete. 



The dead timber is sixty to seventy miles from a railway, 

 and is surrounded by private holdings. It is therefore inac- 

 cessible and can not be used, so must be left to decay, a com- 

 plete loss. 



— Mr. Currie stated that he had examined some remains of 

 dragonflies taken from the stomachs of birds collected in 

 Florida by the Biological Survey of the U. S. Department of 

 Agriculture. These were remarkably well preserved and con- 

 sisted in some cases of almost entire specimens. In the 

 stomach of specimens of the chuck-wills-widow (Antrostomus 

 carolinensis) , a southern and larger relative of the whippoor- 

 will, were a number of seshnines which he referred to Prof. 

 E. M. Walker, of Toronto, who is making a special study of 

 this group. The latter determined them as Epicrschna heros 

 (Fab.) and Coryphcuschna ingcns (Rambur), two of the larg- 

 est dragonflies in the North American fauna. The other 

 dragonflies, determined by Mr. Currie, were small agrionines 

 belonging to the species Ischnura prognata (Hagen) and were
