not reckon any benefit from black spot control, which is even a 

 more important problem, leaving that to the plant pathologists. 

 We conducted the experiment to show that when the weather is 

 fine and black spot not present that spray is not wasted on trees, 

 but that a man pays for his entire four or five applications of spray 

 which the plant pathologists recommend to keep black spot oft' 

 the various varieties in Nova Scotia from two to three times over 

 by controlling three groups of insects: the Fruit worms, the Bud- 

 moths and the Codling Moth, which are present in every orchard 

 and in every year in the Annapolis Valley, often in greater quantities 

 than in our experimental orchard. 



JUNE COLLECTING IN MAINE.— (COLEOPTERA). 



BY C. A. FROST, FRAMINGHAM, MASS. 



June 17th, 1912, found me in the pleasant little village of 

 South Paris, Maine, which is situated on the Little Androscoggin 

 River in the County of Oxford, formerly famous for its bears. 

 The general elevation of the village is about 350 feet above sea 

 level, and the highest point near there is Streaked Mountain about 

 1700 feet. 



This was the second season I had been able to collect in this 

 place, and as I had confined my investigations to the higher land 

 and the hills in 1910, this year I collected along the river and de- 

 voted considerable time to the numerous lumber yards in the 

 village. The most remarkable collecting I have ever experienced 

 was enjoyed in the yard of the Mason Manufacturing Company, 

 which contained huge piles of white pine boards and rapidly 

 diminishing tiers of short logs, mostly white and red (Norway) 

 pine. There were also long piles of slabs, the composition of which 

 showed that spruce, fir, hemlock, and several species of hard 

 woods were used in the establishment. 



Between the river and the yard on the east is a thick stand of 

 young white pines, which extends also a short distance on the 

 north side and forms an enclosed angle into which the afternoon sun 

 beats with tropical fury. In this corner the logs, the tree trunks, 

 along the edge of the woods, a pile of empty packing cases, and the 

 sides of several small buildings, provided resting places for hun- 

 dreds of wood-boring Coleoptera. Chalcophora virginiensis and
