 jarring method was not sufficient. Showering, at first appearance of 

 the curculio, with whale-oil soap and tobacco-water is recommended. 

 Plum-trees bordering water-courses have escaped attack.

Notice of a Scale-insect infesting trees in Albany, believed to be a 

 new species and named by Dr. Fitch as Lecaniam acericorticis. [This 

 species is now accepted as identical with Pulvinaria innumerahilis 

 (Bathvon), for an admirable article upon which by the late J. Duncan 

 Putnam, see the Proceedings of the Davenport Academy of Natural 

 Sciences, ii, 1880, pp. 295-347, pi. xii, xiii.] 



1860. Entomology. No. XXI. — Locust Leaf-miners. (The Country 

 Gentleman, February 2, 1860, xv, p. 82 — 40 cm.) 



Describes and figures the mines in locust leaves sent fi-om Plymouth, 

 Md., which are large and irregular, and have only the upper layer of 

 the parenchyma eaten. Such mines had not been seen by Dr. Fitch 

 and the insect therefore could not be determined. The eggs had been 

 placed on the underside of the leaf, in the angles where the i)rincipal 

 veins branch from the midvein. At first the young larva feeds on the 

 lower parenchyma, which it deserts for the upper layer, the excavated 

 portion below showing subsequently as a small brown spot on the lower 

 surface of the leaf. It probably leaves the leaf for its final transfor- 

 mation. It may possibly be the Locust Hispa, AnoplUes scuteliaris, of 

 whose operations no account had been given. It cannot be the Flat- 

 tened locust leaf-miner, Anacampsis Robiniella, or the slender locust 

 leaf-miner, Argyromiges Pseudacaciella [both of Fitch], which, al- 

 though they form a similar white blister-like spot on the surface of 

 a leaf, yet it is always on the lower surface, it being the lower layer 

 of the parenchyma which their larvae eat. 



1860. The Entomologist. No. XXIL — The Seventeen-Year Cicada. 

 (The Country Gentleman, March 29, 18G0, xv, p. 210—50 cm.) 

 Newspapers are announcing the coming of the 17-year locust the 

 present year. The name of locusts and grasshoppers are synonymous. 

 Their multiplication and ravages, at times, were well known. The 

 name of locust had probably been given to the 17-year cicada by the 

 first European settlers, when they were alarmed by their numbers and 

 noise when seen for the first time. The name of locust, as applied to 

 them, should be discarded for that of cicada, but the desirable change
