makes an oval cocoon of light gray silk. The cocoon is very strong 

 and elastic. The larva of the first brood remains within this cocoon 

 about a week and theu changes to pupa, while the larva of the second 

 brood remains within the cocoon in the larval state through the winter 

 and changes to pupa in the mouth of May. 



Professor Sasaki makes but one suggestion as to remedies, and that is 

 to gather the fallen fruit every day and to dispose of it in such a way 

 as to destroy the larva. We have already written hitn that he will un- 

 questionably find a good remedy in the application of arsenical poisons 

 for the first brood. 



A REPORT ON THE LESSER MIGRATORY LOCUST. 



By C. L. Maklatt, Assistant. 



The following account of the recurrence in injurious numbers of the 

 Lesser Locust {Melanopus atlanis) the present season in the Merrimao 

 Valley near Franklin, N. H., may be considered as supplementary to 

 the extended article in the report of the United States Entomologist for 

 1883, in which a lull record of the earlier occurrence of this species in 

 northern New England (1743-1883) is given ; its life-history and habits, 

 natural enemies, and means against it. 



As stated in the article cited, Professor Eiley visited the infested 

 region in person in 1882 and 1883, and with the aid of some of his assist- 

 ants introduced and explained to the farmers some of the machines 

 for collecting and destroying the locusts successfully used against the 

 closely allied but more destructive Rocky Mountain species. 



The value of these appliances was immediately recognized by the in- 

 telligent farmers of the Merrimac Valley, and numbers of them were 

 constructed after the pattern of the one described on p. 176 of the re- 

 port for 1883 and figured PI. vn, 1; and with the incentive of a bounty 

 of $1 per bushel, granted by the State, they were used with such effect 

 against the locusts in the two years following (1884 and 1885) that no 

 serious injury has, previous to the present season, been occasioned by 

 them since 1880. 



To illustrate the success which attended their use, the statement of 

 Mr. George B. Mathews may be given, viz, that no less than 500 bush- 

 els were caught at the Webster place in 1884, a much less number in 

 18S5, since which time they have occurred in but small numbers. 



A letter to the entomologist from Mr. E. A. Fellows, July 3, 1889, 

 quoted below, again called attention to a serious outbreak of locusts in 

 the Merrimac Valley, near Franklin, N. H., and but a few miles above 

 the region unusually infested in 18S2 and 1883, and seemed to warrant 

 the investigation recorded in this article.
