92 INSECTS INJURIOUS TO GARDEN AND ORCHARD CROPS. 



past season peach was unknown as a host plant. That it prefers the 

 cultivated to the wild plant appears to be assured by recent observa- 

 tions, and there seems little doubt that as fruit growers become more 

 familiar with entomology more instances of injury will come to light. 



The beetles are recorded to feed in June and September, the first 

 beetles seen representing the hibernated generation; those appearing 

 in the fall consisting of their progeny, since there is little doubt that 

 the species is single brooded. It is probable, judging from the date 

 of our correspondence, that the beetles appear sometimes in May in 

 their southern range and continue until July at least in more northern 

 localities, since beetles were observed by Dr. Lintner's correspondent 

 as late as July 10. 



The reported occurrence of the species on chestnut is hardly of suffi- 

 cient value to carry much weight as the statement quoted by Lintner 

 from one of his correspondents was not supported by specimens. 



Wild cherry it seems probable is a natural food plant. Larvae are 

 known to occur on cherry and probably also feed on peach leaves, but 

 were not said to do so by our correspondents. 



DESCRIPTION AND DISTRIBUTION. 



This species, a^ its generic name indicates, is a near relative of the 

 imported elm leaf beetle. It is smaller than the latter, measuring less 

 than one-quarter of an inch in length (4.5 to 5.5 mm ); is bright red in 

 color, with the antennae, eyes, and the exterior portion of the legs black. 

 From G. rufosanguinea, which this species very closely resembles, it may 

 be distinguished by its coarser punctuation, the punctures with dis- 

 tinct intervals and its more shining surface. It was first described by 

 LeConte in 1865 (Proc. Acad. Nat. Sci. Phila., 1865, p. 216) under the 

 genus Galeruca, and afterwards and until recently was classified under 

 Adimonia. A technical description will also be found in Dr. Horn's 

 paper on the Galerucini of Boreal America (Trans. Am. Ent. Soc, vol. 

 xx, p. 76), published in 18!>3. It is there stated to occur from Canada 

 to the New England and Middle States westward to Wisconsin, and is 

 stated on the authority of LeConte to be found also in North Carolina, 

 the type locality. The following list includes more exact localities from 

 recorded notes and from specimens in the National Museum and other 

 local collections: Berlin Falls, Mount Washington, Mount Adams, 

 N. H. ; Cambridge, Mansfield, Mass.; Corning, Ithaca, Ausable Forks, 

 Catskill, N. Y. ; Hartford, Conn.; Spruce Creek, Lebanon, Kicketts, 

 Allegheny (vicinity), and elsewhere in Pennsylvania; Woodstock, Va. 

 (Pratt); St. Ignace, Bellaire, Mich.: Texas; Vancouver, B. C. 



From beetles received from Mr. Heilman June 15 eggs were obtained 

 from which the following description has been drawn: 



The egg.— The egg at first sight is wholly unlike that of the congeneric 

 imported elm leaf-beetle (G. luteola), being of an entirely different form.
