been recorded as feeding on oak, elm, apple, raspberry and common brake, 

 P t e r i s a q u i 1 i n a. Dr Smith states that it lives on most of the orchard 

 trees and small fruits as well as many other trees and shrubs. ' Occasion- 

 ally it is common though not destructive. The full grown larva ranges in 

 length from about ^ to l % inches. The body is short, broad and flat 

 and the head a deep honey-yellow. The caterpillar is so densely covered 

 with long hairs that it appears about one half as long as broad and rounded 

 at each end. The hairs on the thoracic segments are mouse-gray, those on 

 the remainder of the body are pale fawn brown, sometimes dark reddish 

 orange. 



Filament bearer 



A n ia I i in bat a H aw. 



A slaty brown measuring worm about Y\ inch long, remarkable because of the two 

 pair of dorsal filaments near the middle of the body, occurs in June on oak, maple, currant 

 and strawberry. 



This larva is a rather rare one and is noted in this connection because 

 of the peculiar dorsal filaments which at once excite the curiosity of the 

 observer and afford an easy means of identifying this species. 



Archips fervidana Clem. 



Black-headed, yellowish green caterpillars occur in thick web nests on scrub oak in 

 early June. 



This species, kindly determined by Prof. C. H. Fernald, was common 

 in June and July 1901 on scrub oaks at Karner. It was rarer in 1902, 

 indicating a considerable fluctuation in numbers. 



Description. The larvae are nearly 1 inch long with the head and 

 thoracic shield jet-black and the body varying in color from yellowish to 

 olive-green. The dark brown tubercles are inconspicuous. The larvae spin 

 scanty cocoons in their nests, the meshes entangling a mass of excreta. 



The pupa is about 3/g inch long, dark green, ringed with lighter brown, 

 and each segment bears a conspicuous row of stout spines with another row 

 of smaller ones behind. 



The adult has reddish brown fore wings, which are rather clouded with
