cacy noted. Their source in the above infestation can not be indicated : 

 their manner of spreading is given. Cleanhness is the most efficient 

 preventive. Fumigation with sulfur and washing with kerosene 

 emulsion is recommended for infested rooms. The mites work super- 

 ficially and the infested meat may be dijiped in a weak aqueous solu- 

 tion of carbolic acid after the mites have been removed so far as 

 possible. 



Canker worms. (Country gentleman. April i, 1897. 62 : 248, col. i, 



2, 18 cm) 



A correspondent from Spencerville, Ind., requests a remedy for an 

 insect which has been injurious for the past three years, and causes the 

 apple trees to appear as though the tops had been killed by fire. The 

 insect is identified as most probably Anisopieryx venmta Peck, the 

 spring canker worm, although it may be the fall canker worm, Anisop- 

 ieryx pometaria Harris. The life history is briefly given, and banding 

 trees or spraying with paris green is recommended. 



Apple-tree borers. (Country gentleman. April 22, 1897. 62:307, col. 



3, 18 cm) 



In reply to an inquiry from Harrison, N. Y., of proper treatment for 

 apple-tree borers, it is stated: the principal apple-tree borers are two — 

 the ' round-headed,' Saperda Candida Fabr., and the ' flat-headed,' Chry- 

 sobothris fenwraia Fabr., — the former attacking the base of the tree and 

 the latter the upper part of the trunk. Some information of the species 

 is given, and the best methods for preventing their injuries by means of 

 washes, paper bands about the trunk, and digging out the larvae. 

 Where detailed information of habits, remedies, etc., of these pests 

 may be found. 



Grasshopper. (Country gentleman. April 29, 1897. 62:326, col. 3- 



4, 1 1 cm) 



The two rows of eggs touching one another and overlapping in each 

 row sent for name from Augusta county, Va., are those of the ' angular- 

 winged katydid,' Microccntniin retinervis Burm., of the southern states. 

 The eggs are described and the manner of their peculiar deposit (over- 

 lapping) given. Dr Riley's account of the insect and its oviposition is 

 referred to. In one instance the eggs were placed on a shirt collar in a 

 laundry instead of their usual place on a small twig of a tree. 



Cow-horn fly. (Country gentleman. May 6, 1897. 62:350, col. i- 



2, 17 cm) 



To a request for a remedy for the attack of the above-named insect, 

 known scientifically as Haeinaiobia serrata Rob.-Desv,, recommenda- 

 tion is made of breaking up the cow droppings to promote their rapid 

 drying, in which the eggs are deposited, and treating the manure 

 in the stables with lime. Kerosene emulsion applied with a spraying 

 machine to the cattle is recommended. Other remedies are the appli- 

 cation of coal tar and lard, pine tar and grease, tallow and carbolic 

 acid, and dusung the animals with tobacco dust or the X. O. dust.
