far as to include the Coleoptera, Lepidoptera, Hemiptera and 

 Ortboptera, which are now represented by 25,000 cards. The 

 other orders of insects are still to be copied from the thin slips • 

 upon which they were first written. This catalogue is of very 

 great assistance in our work, and saves a vast amount of time in 

 looking up the literature of any insect. 



Many letters have been received from different parts of the 

 State about the depredations of certain common insects, of which 

 the most important are the army-worm, the canker-worm, the boll- 

 worm, the Vanessa butterfly, the red-humped caterpillar, the vaga- 

 bond cr ambus, the raspberry-cane girdler and the wrinkled scolytus. 

 Information concerning these insects and what can be done to hold 

 them in check will be given later in a bulletin. 



The studies on cranberry insects have been continued, and sev- 

 eral insects discovered injuring cranberries, which had not pre- 

 viously been known to feed upon this plant. 



The common span-worm of the Cape Cod bogs has been bred, 

 and proves to be Emattirga faxonii Miuot. I had long suspected 

 that this insect fed on the cranberry, as the moths were found in 

 abundance on bogs infested with the span-worm. 



Noctaa c-nigrum Linn, was found quite abundant on many bogs. 

 They remained, during the day, concealed in the sand and fallen 

 leaves, and fed by night on the leaves at the tips of the runners, 

 and on the berries, eating out the whole inside through a large 

 hole in one side. Many of the cranberry growers had supposed 

 this to be the work of span-worms. 



The^ red-striped span-worm was found on several of the bogs 

 feeding on the leaves. This larva is about three-fourths of an 

 inch in length, with the dorsal surface yellowish, ornamented with 

 a longitudinal reddish band with short, oblique branches extending 

 from it, and sprinkled with fine white dots. A lateral red stripe 

 occurs on the first few segments of the body. These span-worms 

 were sent to the insectary, where the moths emerged August 11, 

 and proved to be Eupitliecia implicata Walk. 



The green span-worm was found on several bogs, where it was 

 said to be very injurious. Specimens sent to the insectary died 

 on the way, and therefore they have not been bred. Thamnonoma 

 argillacearia has been taken flying on the bogs, in such numbers 

 and under such circumstances as to lead me to suspect that it is 

 tlie moth of the green span-worm. Thamnonoma sulfararia has 

 also been taken flying over bogs under such circumstances as to 

 lead to the suspicion that it may also be a cranberry insect. 



Cramhus topiarius has been bred by Mr. S. H. Scudder, as a 

 girdle-worm ; and while I have for a long time been convinced
