Peach Root Aphis. (Gardener's Monthly and Horticulturist, Phila., 

 September, 1884, xxvi, pp. 271-2 — 29 cm.) 



A root aphis which is destroying all the seedling peach trees of Mr. 

 Lorin Blodget, at Philadelphia, is believed to be Myzus persicce Sulzer. 

 For destroying it the following are suggested : Hot water, leached ashes 

 and sulphur, bisulphide of carbon and soluble phenyle. As superior to 

 the above, the sulpho-carbonates are recommended, and Iff. Dumas, of 

 the French Academy, quoted upon their use. 



A New Rose Pest — Homoptera Lunata. (Country Gentleman, 

 for September 1, 1884, xlix, p. 737, c. 1-2 — 25 cm.) 



Caterpillars feeding at night on rose buds in a rose-house in Madison, 

 N. J., proved to be Homoptera lunata. This food-plant had not been 

 previously recorded. The life-history of the species, as detailed by 

 Prof. French, is given, together with Guenee's description of the cater- 

 pillar; also mention of the sexual difference in the moths, and the 

 distribution of the species. Injury from the larvae in rose-houses best 

 prevented by hand-picking them.

 1888, pp. 57-59.] 



Jumping Seeds. (Country Gentleman, for September 11, 1884, xlix, 

 p. 757, c. 1-2 — 40 cm.) 



The seed-vessels described ; said to be a species of Euphorbia. The 

 contained insect (a lepidopter) causing the motion, was described and 

 named as Carpocapsa saltitans, by Prof. Westwood, in 1858— later by M. 

 Lucas as C. Deshaisiaua. The interesting generic relation of the insect 

 is referred to, its leaps described, their cause explained, and period of 

 emergence of the moth stated. Three other kinds of jumping seeds are 

 known. Reference to further information.

The "White Grub — Lachnosterna fusca. (Country Gentleman, for 

 September 11, 1884, xlix, p. 757, c. 2-3 — 22 cm.) 



In reply to inquiries from West Stockbridge, Mass., of remedies, etc., 

 reference is made to a paper upon the insect giving about all that is 

 known of it published in the Forty-third Annual Report of the New York 

 State Agricultural Society, for 1883. The starvation remedy, as there 

 given and believed to be effectual, is quoted.

 in the straw examined than elsewhere seen ; the wheat greatly shriveled ; 

 life-history of the insect; its description; two parasites infest it; reme-
