anus. The legs are dark brown or black on the outer base and have a 

 heavy black blotch at the base. The prolegs are marked on their outer 

 side by a somewhat triangular, black or very dark brown spot. The 

 cocoon is double walled, the outer wall being loosely woven and it is dull 

 white or pale brown in color, and is from 12-14 mm in length. 



The larvae were found in considerable numbers in the month of August 



feeding on the foliage of common chokecherry (P r u n u s v i r g i n i a n a) 



at Jamaica Plain Mass. I-^rom these larvae a number of female imagos 



were bred in the latter part of the following May. 



Cherry leaf beetle 



Galcriicclla cavicollis Lee. 



A small red leaf beetle, about '/s inch long, eats in midsummer irregular round holes 

 in the leaves of wild cherrytrees. 



This little species is somewhat abundant in the Adirondacks on wild 

 cherry, and was repeatedly observed by the writer in August 1900. It was 

 so numerous that the foliage on many of the trees was badly riddled, and 

 large numbers of the beetles could be collected with little trouble. This 

 species has also been observed by Dr Lintner injuring cultivated cherry 

 trees on several occasions.

Apple tent caterpillar 



Malacosivna auicriiana Fabr. 



Web tents in the forks of wild cherry and apjile trees in early spring, are most char- 

 acteristic of this very common spei ies. 



This cater[)illar is well known because of the conspicuous and charac- 

 teristic tents or webs it spins in the forks of wild cherry and apple trees. 

 The full grown caterpillar is abcut two inches long and may be easily dis- 

 tinguished from the closely allied forest tent caterpillar, Malacosoma 

 disstria Hiibn., h\ its possessing a continuous white line down the 

 middle of the back, whereas the forest species has a row of silvery white, 

 diamond-shaped spots. This caterpillar has marked preferences for the
