402 STATE HORTICULTURAL SOCIETY. 



This was the most common celery leaf roller found this season. It was 

 found more or less common in every locality visited. There are at least 

 two broods and probably three. Of the first brood noticed the larv8& 

 became full grown about the first of August and pupated early in the 

 month, remaining from five to nine days in this state before issuing as 

 moths. The next brood reached maturity the latter part of September and 

 probably remain over winter as pupse. Previous to this the species has 

 been bred on clover and common buttercup (Ranunculus acris). 



The larvae are light green all except the tips of the mandibles (jaws), 

 labrum (upper lip), and front feet which are black, and the head and 

 thorax which are lighter— almost a flesh color. They live in leaves drawn 

 together around them by a web which they spin, and feed on the adjoining 

 leaves. They pupate in the same leaves in which they live. The little 

 moths are a bright sulphur yellow with a network of small red lines and 

 larger reddish brown bands on the primary wings. The hind wings are 

 dusky. The band on the front wings varies considerably, the two extremes 

 of the specimens reared being shown in the figure. 



Should the species become still more common, and perceptibly reduce 

 the foliage of the celery, it is probable that a great deal can be done to 

 prevent the attack by cleaning up all leaves and refuse material left in the 

 field in the fall and burning it. From our present knowledge, it would 

 seem that this would destroy many winter pupse. 



THE CELERY TORTRIX {Sericoris bipartitana, Clem). 



Only occasional specimens of this species were found. The larvae feed 

 on the leaves and live in a gallery made by drawing several leaves together. 



They are half a inch long, or a little 

 more, quite slender and very active, 

 throwing themselves with great vio- 

 lence when taken from the case. 

 They are a dark greasy brown (almost 

 black) with black shield on thorax,, 

 legs and plate on terminal segment 

 black, prolegs and under side lighter.

 appeared as a moth two weeks later. The moth is black and white with 

 dark posterior wings and light abdomen. Prof. Fernald says the species, 

 has never been bred before to his knowledge.
