this instance a large number of specimens in all stages were received. 

 The species is larger than any of the native species of Catorama, 

 and it is strange that its presence in the United States has not been 

 located hitherto. On account of its large size it is likely to cause 

 much more damage to cigars than the cigarette beetle. 



-W. D. Hunter exhibited a sketch of a very successful device 

 for breeding Simulium perfected by Mr. A. W. J. Pomeroy during 

 his connection with the Illinois State Laboratory of Natural His- 

 tory. The device provides the two essential requisites in breeding 

 Simulium larvae, that is food and well aerated water. It consists 

 essentially of two wooden tanks through which water is allowed to 

 pass. The first of these tanks is partly filled with algse. The 

 water passing through this tank becomes impregnated with the 

 detritus of the alga?. It then passes through a pipe to a second 

 tank in w r hich the actual breeding takes place. This second tank is 

 provided with lantern globes lying on the bottom on their sides but 

 slightly tilted upward in the direction from which the water flows. 

 When the apparatus is in operation the water passes into the second 

 tank forming minute waterfalls when it flows into the lantern 

 globes. The flow can be regulated so that the discharge through 

 the chimneys is as shallow as a quarter of an inch. It is in this 

 stream that the larvae or eggs are placed. In actual practice it was 

 found that in this situation they were perfectly at home, not show- 

 ing any tendency to leave the chimneys. 



In the original apparatus the tanks were about 5 feet long. This 

 gave sufficient space in the lower tank for about twenty lantern 

 globes which would allow the breeding of as many isolated lots of 

 Simulium larvae in a space considerably smaller than the top of an 

 ordinary table. 



Mr. McAtee presented the following note: While exploring 

 Lake Pomme de Terre, near Hamburg, Louisiana, last September, 

 my old negro guide inquired whether I would like to see how fish- 

 bait was obtained in that locality. As I expressed an interest in 

 the procedure he pulled up a long leaf stem of Nelumbo lutea. All 

 of the stem except a foot or two nearest the leaf was thickly studded 

 with larvae and cocoons of Donacia. The part of the stem bearing 

 them was probably buried in the almost liquid bottom of the lake, 

 the upper layers of which are composed of coarse vegetable detritus.
