would enable us to figure fully three and a half broods for Fort Collins, 

 where we know there are but two broods. 



In working to determine broods there are two factors that should be 

 kept in mind. In the first place, the individuals of a brood do not all 

 appear at one time but are usually distributed over many days, often 

 several weeks. We have had the first brood of the codling moth appear- 

 ing in our cages for over two months. And then the early individuals of 

 the last brood of an insect begin to hibernate or otherwise prepare to go 

 over winter long before the late individuals of the brood. Citing the cod- 

 ling moth again as an instance, the larvae of the early part of the second 

 brood begin to spin up to pass the winter as larvae early in August at Fort 

 Collins but the late members of the brood are in apples till winter. 



Doings of Societies. 



A- regular meeting of the Chicago Entomological Society was 

 held in the John Crerar Library April ijih. Seven members 

 were present. President L,ongley in the chair. Mr. Healy 

 gave an interesting talk on edible insects. Among other 

 things he spoke of the Digger Indians eating grasshoppers. 

 He also said he had heard his father tell of the troops in the 

 Mexican war eating ants on their hardtack when food was 

 scarce. Prof. Westcott told of an experiment which C. V. 

 Riley had made on baked grasshoppers. It was suggested 

 that the Society indulge in grasshopper cakes in the coming 

 season. Mr. L,ongley spoke of a Mexican delicacy -the bottle 

 ant. Many other instances of insects being eaten were dis- 

 cussed. 



A meeting of the American Entomological Society was held 

 April 24th. Dr. Calvert, President, in the chair. Fourteen 

 persons were present. Dr. Skinner exhibited a new variety of 

 Papilio polyxenes Fab. Mr. Laurent said he had had a speci- 

 men of Thyreus abbotti emerge to-day. The pupa was kept 

 outside all winter. He attributed the early emergence to the 

 warm spell. Mr. Wenzel said he and Prof. Smith had recently 

 visited Anglesea, N. J., and had examined the ponds and 

 found multitudes of mosquito larvae. Mr. Wenzel predicted a 

 large crop of the images this summer. Mr. Wenzel also 

 reported the capture of both sexes of Batrisus ione at Angle-
