370 FORVY-FOUR'IH REPORT ON THE StATE MuSEVM 



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. Remedies for this and other Coccidce are given. 



Insects in Illinois. (Country Gentleman, for July 4, 1878, xliii, p. 

 425, c. 2,3 — 15 cm.) 



Insects sent from Champaign Co., 111., as Coccus hesperidum, 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 be as abundant in future years. 

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

 innumerdbilis Eathvonj. 



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

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



♦ Xylehorus pyri (Peck) [dispar Fabr.] and Grypturgus {Monarthrum] 

 mali (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 Thelaxes by Walsh, 

 and to Glyphina 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 — 11cm.) 



Larvae 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.)
