Report of the State Entomologist. 323 



The Two-marked Tree-hopper. (Country Gentleman, for October 13, 

 1887, Hi, p. 783, c. 2-3 — 22 cm.) 



Insects described, sent from Glen Cove, Long Island, N. Y., as occur- 

 ring only on Juglans rapestris, are a variety of Enchenopa hinotata 

 (Say). Comparison is made with typical examples of this species, and if 

 the differences are constant, the form sent will at least merit a varietal 

 name. They resemble examples of Enchenopa taken from a honey 

 locust at Bennington, Vt. Juglans rapestris is native to Texas, Arizona, 

 and New Mexico. Remedies for this insect are, removing and burning 

 the twigs bearing the egg-deposits, indicated by the conspicuous 

 white egg-coverings, and driving away the timid winged forms. 



Mites on Arbor Vitse. (Country Grentleman, for October 20, 1887, lii, 

 p. 800, c. 2— 8 cm.) 



The mite infesting an arbor vitse as noticed in the Country Gentle- 

 man for September first, is believed to be Tetranychus telarms, "the red 

 spider," or a nearly allied species. Its occurrence on this food-platit is 

 new. 



Asparagus and Pear-Blight Beetles. (Country Gentleman, for Octo- 

 ber 27, 1887, lii, p. 817, c. 3-4—35 cm.) 



Beetles appearing, for the first, this year at Annapolis, Md., are iden- 

 tified as Grioceris asparagi. Its distribution in this country is stated, 

 and for remedies air-slacked lime, and chickens as collectors, recom- 

 mended. 



The beetles taken while commencing to bore in the trunk of a young 

 apple tree, are Xyleboi'us pijri (Peck). Its two forms of attack — the 

 burrowing of the larva near and into the bud, and by the mature beetle 

 in the spring, into the trunk, are described. Remedies : cutting off and 

 burning infested twigs, and poisonous or repellant washes. 



"White Grub Attack on Wheat. (Country Gentleman, for October 27 

 1887, lii, p. 817, c. 4 — 24 cm.) 



A white grub sent from Abingdon, Va., where in October, it is 

 destructive to young wheat, seems not to be that of Lachnosterna fusca, 

 but of some allied species. Description of the grub is given, and of its 

 method of traveling on its back. No remedy is known for an attack of 

 this kind. The grubs should have been destroyed when the meadow 

 was broken up for wheat, by methods mentioned. Should the grubs, 

 after heavy rains, show themselves above ground, poultry would 

 reduce their number materially.. 



The Bag- Worm. (Country Gentleman, for November 3, 1887, lii, 

 p. 837, c. 2-4 — 54 cm.) 



An insect destroying an arbor vit^ hedge in Plainfield, N. J., is the 

 bag-worm, Thyridopteryx ephemerceformis, of which the habits are 

 ^iven, and reference to its bag ; also, the degraded habits of the female ;
