SOUTHERN SPREAD OF THE COLORADO POTATO-BEETLE. 



Apropos to the note on page 22, current volume of Insect Life, allow 

 me to state that there are good reasons for the belief that Doryphora 

 10-lineata occurred at Jackson, Miss., in April, 1888. While at Vicks- 

 burg, late in April, last year, I was told of their appearance on po- 

 tatoes, in the vicinity of Jackson, and took pains to question my in- 

 former as to their looks, and his replies left no doubt as to the identity 

 of the species.— [F. M. Webster, La Fayette, Ind., July 25, 1889.] 



THE GAS process FOR SCALE INSECTS. 



While at Orange I learned of four persons who had used the gas pro- 

 cess for ridding their trees of the red scale, and they much preferred it 

 to spraying. Dr. W. B. Wall, the county treasurer of Orange County, 

 told me that it cost him about one and a half times to fumigate what it 

 would to spray the trees with a wash costing one cent a gallon, and that 

 one fumigation accomplished as much good as three sprayings, besides 

 leaving the tree in a better condition. There is still considerable injury 

 to the leaves of trees fumigated in very hot weather, but I hope to over- 

 come this by using a tent constructed from a different material than 

 those heretofore used, as there is reason for believing that it is the rays 

 of light rather than of heat that decompose the gas. — [D. W, Coquil- 

 lett, Los Angeles, Cal., July 22, 1889.] 



A SAD BLUNDER IN NO. 2. 



Unfortunately I allowed a very careless error to appear in print in 

 Fo. 2 in the item entitled "A Peculiarity of Certain Caddis Flies." The 

 title should read instead of " Caddis Flies," " Trichopterygid Beetles." 

 In reading the German article in the Entomologische Zeitung the word 

 " Trichopterygier " impressed me as referring to the Trichoptera and I 

 allowed the item to go to press before discovering the blunder. Pro- 

 fessor Riley was absent and about to leave France, so that copy of the 

 item was not sent him, as the mistake would otherwise never have oc- 

 curred.— [L. O. H.]
