316 Forty-first Report on the State Museum. 



The Seventeen-year Locust — - Cicada septendecim. (Tlie Owl, Organ 

 of Agassiz Association, No. 711, Glens Falls, N. Y., May, 1887, ii, pp. 

 17-19, figs. 1-5.) 



The interest attaching to this insect from its long period of develop- 

 ment, noticed ; also, a thirteen-year Soutliern race ; number of broods 

 in the United States, and the number occurring in the State of New 

 York ; the next appearance of the New York broods. A resume of the 

 life-history of the insect is given, and reference made to Cicada tibicen. 



[A Root Aphis of the Hop-vine.] (The Waterville [N. Y.] Times, for 

 May 6, 1887, p. 2, c. 3 — 32 cm.) 



Some insects sent in soil from a hop-vine hill in Waterville, are 

 recognized as belonging to the group of Bhizohmias, or underground 

 aphids, which feed on the roots of plants. They can not be referred to 

 any described U. S. species, as they differ from all such. A description 

 of them is given. They are viviparous females, and are now producing 

 living young. As these develop, it may be possible to identify them 

 with some known above-ground species. 



Lady-birds, Leaf and Carpet Beetles. (Country Gentleman, for May 

 12, 1887, lii, p. 381, c. 1-3, figs. 1-6 — 80 cm.) 



Importance of such a knowledge of lady-birds as should prevent such 

 destruction as they have been recently subjected to from having been 

 mistaken for the carpet-beetle ; the regard for them in Europe ; how 

 their form and markings may serve for their recognition ; the specific 

 names that indicate their usual spotted ornamentation ; figures of some 

 species ; how the Chrysomelidce with which they are liable to be con- 

 founded, maybe distinguished, particularly the "tortoise beetle; " the 

 tarsi as separating and distinguishing the two families ; description and 

 figures of the carpet-beetle, Anthi'erms scrophularias. 



The Little Winged Pest. (The Albany Argus, for May 16, 1887, p. 2.) 



An abstract from a pajDcr read before the Dana Natural History 

 Society of Albany, on the Mosquito, treating of the numerous species ; 

 their distribution ; means of protection against them ; the bite ; 

 palliatives of the bite ; only the female bites ; the biting organs ; 

 use of the mosquito ; the mosquito as a host for filariee ; perhaps one of 

 the ten plagues of Egypt; the life-history and transformation of the 

 insect. 



Another Apple-Tree Pest. (Country Gentleman, for May 19, 1887, 

 lii, p. 398, c. 4 — 10 cm.) 



A fiea-beetle sent from Coleman's Falls, Va., where "it caused the 

 apple-trees to look as if the buds had been burned out with a hot iron," 

 is Crepidodera rufipes (Linn.). Although G. Helxines has been reported 

 as injurious to apple leaves in Illinois, this has not previously been so 

 reported. The reasons are given why neither of these may be expected 

 to prove serious pests of the apple. [See revision and extension of the 

 above in pages 221-223 of this Report.]
