A PREDACEOUS CAPSUS. 



An interesting note is published in the Entomologische Nachrichteriy 

 Jahrgang xvii, heft 2, by C. Verhoeff, to the effect that he has ob- 

 served Capsus capillaris feeding upon ApJiis rosae. An individual was 

 observed to insert its proboscis in the abdomen of the jjlant-louse be- 

 tween the honey tubes. 



WATER BEETLES FOUND IN AN OLD GASOMETER. 



An interesting note is published in the Entomologist's Monthly Maga- 

 zine for March, 1890, which indicates that Dytiscus marginalis may live 

 under extraordinary conditions. A number of specimens were found 

 living in rusty water at the bottom of a hole left when the iron casing 

 of a gasometer had been removed, both water and mud being strongly 

 impregnated with gas. Mr. T. H. Hall, the writer of the note, who 

 secured the specimens, states that they carried a strong odor of gas 

 even after they had had two or three baths of fresh water. The old 

 gas-holder must have been their home for a long period of beetle life^ 

 judging from the time of year when they were found and from the num- 

 ber of both sexes seen. The water was partly inclosed and was quite 

 stagnant, being unconnected with any other water. They could have 

 migrated had they desired to do so. They were quite active, and seem 

 undoubtedly to have remained entirely from choice. 



HICKORY HORNED DEVIL INJURING COTTON. 



Through Dr. Tate Powell, of Starke, Fla., we learn that the larva of 

 atheroma regalis has been doing considerable damage to sea-island 

 cotton in Bradford County the present season. 



A NEW FOOD-PLANT OF THE FLUTED SCALE. 



Mr. C. R. Orcutt, of San Diego, Cal., has recently sent us specimens 

 of leery a purchasi from the Mission Valley, which he found upon 

 Hymenoplea salsola. This plant has not previously been mentioned as 

 a food-plant of the Fluted Scale. 



TEMPfeRATURE OF WEEVIL-INFESTED PEAS. 



On page 59, volume i, Mr. Howard published a short note concerning 

 some observations by Judge Lawrence Johnson, upon a remarkable 

 increase of temperature of a mass of cow peas infested by Bruchus scu- 

 tellaris. The same observation has recently been made again by Mr. 

 William D. Richardson, of Fredericksburg, Va. We quote from a let- 

 ter from Mr. Richardson addressed to Mr. Schwarz, dated November 1, 

 1891 : 



August 13 I had occasion to move a bag of peas which had been iu the corner of 

 my room (in our farm house) for a month or more, and from which thousands of 

 Bruchus scutellaris had been emerging. On touching the bag I was surprised at the 

 temperature, and observed as follows :
