A Grapevine Coccus. (Country Gentleman, for July 4, 1878, xliii, 

 p. 423, c. 3, 4 — 19 cm.) 



A piece of grapevine from Cleveland, O., is covered with the scales of 

 a Coccus, of which no description is found. The scale, in two forms 

 and sizes, is described, together with the eggs beneath them. Under one 

 scale were 1,054 eggs. Kemedies for this and other Coccidce are given. 



Insects in Illinois. (Countr}^ Gentleman, for July 4, 1878, xliii, p. 



425, c. 2, 3 — 15 cm.) 



Insects sent from Champaign Co., 111., as Coccus hesperidwn, and 

 occurring on soft maple, osage orange and black walnut (estimated, p. 

 421, c. 1, at more than 100,000 on each tree), are identified as Lecanium 

 acericola, figured in American Naturalist, i, p. 14, and in Packard's 

 Guide, p. 530. The twigs received are swarming with the active, newly- 

 hatched lice; the scales are described, with their projecting cottony 

 masses. It will probably not continue to beasabundant in future years. 

 See notice of the same insect in issue of July 25 [proves to be Pulvinaria 

 innumerabilis Kathvon]. 



Apple-Bark and Pear-Blight Beetles. (Country Gentleman, for 

 July 18, 1878, xliii, p. 455, c. 1, 2 — 36 cm.) 



Xyleborus p;/ri (Peck) [dispar Fabr.] and Crypturgus {Monar thrum] 

 mail (Fitch) are found associated with pear-blight by a gentleman in 

 Bradford county. Pa., supposed by him to be the cause of the blight. 

 They are described with notice of their injuries, preventive measures, 

 and their distribution. 



The Cockscomb Elm-Gall. (Country Gentleman, for July 18, 

 1878, xliii, p. 455, c. 2 — 16 cm.) 



This gall, of which inquiry is made from Staunton, Va., occurs on the 

 Ulmus Americana, and the insect producing it is the Bryoscripta ulmi- 

 cola of Fitch, subsequently removed to the genus TJielaxes by Walsh, 

 and to Ghjphina and Colopha by later writers. No remedy is known 

 against the attack of this insect.

An Apple Tree Insect. (Country Gentleman, for July 25, 1878, 



xliii, p. 471, c. 1 — 11 cm.) 



Larvfe in crevices of a section of a limb — not in a burrow— varying 

 in length from one-eighth to one-fourth of an inch, and apparently 

 hymenopterous, can not be identified. They may be of parasitic origin. 



The Maple Bark Scale Insect — Lecanium acericorticis. (Country 



Gentleman, for July 25, 1878, xliii, p. 471, c. 1, 2 — 34 cm.)

 Albany, its naming, and remedies suggested for it — for a long time over-
