276 Forty-ninth Report on the State Museum 



(Linn.). It can be destroyed by kerosene emulsion or a whale-oil 

 soap solution if applied at the hatching of the eggs and prior to the 

 curling of the leaves. 



Repelling the attack by mulching the plant with tobacco stems, as 

 reported, would be a valuable preventive if it should prove, on fur- 

 ther trial, effective. 



The Bean Weevil. (Country Gentleman, for May 16, 1895, Ix, p. 389, 

 cols. I, 2 — 17 cm.) 



To an inquiry from Buder Co., O., of the construction of kilns for 

 killing the bean weevil, reply is made that any excess of heat used in 

 killing the weevil in stored beans would endanger their germination. 

 Professor C. E. Weed's experiments in killing the pea weevil in an oven 

 exposure of 146'' Fahr. for an hour, are referred to. Exposure of in- 

 fested beans to the vapor of bisulphide of carbon is preferable to heat. 

 Where description of the " Tracy House " for killing the weevil 

 with bisulphide of carbon, may be found. 



The Bean Weevil. (Country Gentleman, for May 23, 1895, Ix, p. 408, c. 

 3 — 6 cm.) 



Answer is made to a correspondent from Binghamton, N. Y., that 

 the weevil comes from eggs deposited upon the pods, and no means 

 are known for preventing the deposit. As it is a rather local insect, 

 all bean growers in an infested locality should combine in killing the 

 insect soon after the gathering of the crop, by the bisulphide of carbon 

 treatment or some other efficient remedy. 



Millepedes and Wire- Worms. (Country Gentleman, for May 30, 1895, 

 Ix, p. 423, cols. I, 2 — 23 cm.) 



From 40 to 60 "black wire-worms" reported as occurring in single 

 hills of melons, in Pattersonville, N. Y., are millepedes or " thousand- 

 legged worms." What may be done to prevent them infesting crops, 

 as in not using manure in which their eggs occur, applying soot, lime- 

 water, trapping with baskets of damp moss, slices of potato, and cabbage 

 leaves. Figures of wire-worms and of millepedes are given to show 

 their difference. 



Carpet-Eaung Insects. (Country Gentleman, for May 30, 1895, Ix, p. 

 423, c. 3 — 16 cm.) 



Insects sent from Louisville, N. Y., from underneath carpets, are the 

 larvge of Tinea pellionella (one of the three species of clothes-moths) 

 and oi Attagemis piceus, the black-carpet beetle. An account of each 

 is given and how they may be destroyed. The supposed clothes- 

 moths attracted to light in the evening are not clothes-moths, but are 

 species that enter through open windows and are harmless within doors. 



Plum-Tree Aphis. (Gardening, for June i, 1895, iii, p. 281, c. 3 — 16 cm.) 



The aphides sent from Eaton, O., had all been devoured by the 

 larval Syrphus flies and a Coccinella p-notata inclosed with them, but
