Their transformation to pupae occurs at different periods, sometimes 

 earlier, sometimes later, according to the forwardness of the season, 

 but usually not much later than the middle of July." Dr. Harris 

 added that the moths are yerj abundant in New England from June 

 15th till the end of August. 



There are many records of the capture of the moths at lights or 

 at sugar baits. In Canada the dates of capture range from June 

 19th till October; in New York the dates are between June 15th 

 and September 23d. In a series of six trap-lanterns kept lighted 

 every night during the spring, summer, and fall of 1889, we cap- 

 tured in all 21 of the moths on the following dates: 1 on June 

 10th, 2 on June 15t]i, 2 on June 2 1st, 6 on June 25th, 6 on June 

 28th, 6 on July 2d, 1 on August 28th, and 1 on September 20th. 

 Although the flight of the moths extends over so long a period there 

 seems to be but one brood of the insect in the course of a year in 

 this latitude. 



The eggs are doubtless mostly laid in June and July and the cut- 

 worms hatching therefrom attain about half their growth before 

 going into winter quarters. Prof. Forbes says most of the cutworms 

 finish their growth in Illinois in April and early May. In 1871, 

 Mr. Saunders found the half-grown cutworms under chips and logs 

 in open fields in Canada early in May ; these became full-grown by 

 May 25th and one pupated the next day. From nearly full-grown 

 specimens taken on peach trees April 29tli we bred the moth on 

 June 11th and 12th. 



Thus there is yet much to be learned of the life-history of this 

 well-marked cutworm. 



4. The Dingy Cutworm.

This is one of the most common cutworms in our State, and yet 

 only 3 per cent, of the specimens found on peach trees in Monroe 



* The scientific name of this insect has been the source of much discussion in 

 recent years. Much of the confusion has resulted from the fact that it was first 

 described in Enghmd from sui)posed Euglish si^ecimeus. We have made a criti- 

 cal historical investigation of the systematic literature of the species, and have 

 embodied the results in detail in an illustrated article in the Canadian Entomolo- 

 gist for November, 1895. At present, we believe, the evidence warrants the use 

 of the above name for the insect; the generic name may have to be changed to 

 Agronoma in accordance with the latest revision of the old and unwidely genus 

 Agrotis.
