Ants on Fruit-Trees. (Country Gentleman, for July 6, 1893, 

 Iviii, p. 523, c. 1 — 19 cm.) 



Ants occurring on fruit-trees are believed not to be injurious to the tree or 

 fruit, but are attracted to feed on the "honey-dew" secreted by the infesting 

 plant-Uce or aphides. Two species often met with are Camponotus hercu- 

 laneus (Linn.) and Cremastogaster cerasi (Fitch). The aphides cause the 

 injury to the foUage; they may be killed by spraying the first that appear, 

 before they find shelter in the curled leaves, with tobacco water, soapsuds, 

 or kerosene emulsion.

A Kew Grapevine Pest, (Country Gentleman, for July 6, 1893, 

 Iviiii, p. 523, c. 1, 2 — 11 cm.) 



In reply to a correspondent from North Carolina who writes of the habits 

 and ravages of Anomola marginata, for the first time, on his grapevines, 

 answer is made, that although the beetle is widely distributed over the 

 southern part of the United States, it has not been recorded as injurious to 

 the grape, except in a single instance, in Louisiana. Shaking them from 

 the vines into a collector such as recommended by Prof. Smith for the col- 

 lection of the rose-bug, is, perhaps, the best that can be done to reduce their 

 numbi^r. Paris green might safely be used before the grapes begin to ripen.

Ants on Peonies. (Country Gentleman, for July 6, 1893, Iviii, 

 p. 5-24, c. 1, 2 — 12 cm.) 



Peonies in Albany thickly populated with black ants fail to give perfect 

 blossoms. The ants are probably merely drawn to them to feed on the sweet 

 secretion of the buds, or on the small insects that visit them — possibly an 

 aphis, but no species is recorded as occurring on the peony. Ants have been 

 seen to carry away small insect visitors of the peony which may have been 

 injuring the blossoms. In Florida they are serviceable in preying on some 

 of the smaller insect pests of the orange.

Three-lined Leaf- Beetle. (Country Gentleman, for July 'o, 1893, 

 Iviii, p. 524, c. 2 — 9 cm.) 



An insect destructive in gardens in Buffalo, N. Y., is identified as Lenia 

 trilineata, conspicuously marked with three black lines on its wing-covers, 

 and belonging to the destructive family of Chrysomelidce. It is, at times, 

 abundant, and often injurious to the potato crop Remedies are, beating 

 from the plant into water and kerosene, or spraying with Paris green. 



A Useful Beetle. (Country Gentleman, for July 6, 1893, Iviii, 

 p. 521, c. 3 — 10 cm.) 



A beetle (described) found in Albany in a box of Sicily lemons when 

 opened, is the Calosoma sycophanta, of Europe, closely resembling our 

 beautiful Calosoma scrutator. These Carabidce are serviceable in their
