APPLE TREE PESTS. 



Sohonherr'8 'WeoWl and the Orchard Moth. — Asa Fitoh, M. D., Salem, N. T. 



Salem, JV. Y., June 30, 1853. 

 Hon. B. P. Johnson: My Dear Sir — The Michigan insects 

 reached me in safety. They pertain to the weevil family (Cur- 

 culionid;e), and are one of the largest of that kind of insects 

 which we have in this country. They are the Pachyrhynchus 

 Sc/ionfterri, so named by the late Rev. Mr. Kirby, in honor of the 

 Swedish entomologist Schonherr, who has devoted a great deal 

 of attention to this family of beetles, so noted for the injuries 

 which they inflict, and who has published several volumes upon 

 them. Mr. Kirby's description of this species may be found in 

 the Zoology of the Northern Parts of British America, vol. iv, 

 page 103. It also appears, from the short description given in 

 Turton's System of Nature, vol. 2, page 264, to be the species 

 named Curculio Jfoveboracensis, or the New-York weevil, by Fors- 

 ter; but not having Forster's work at hand, I am unable to speak 

 decidedly. It is rather a rare insect, I should judge, for I have 

 never seen but three specimens of it heretofore. One of these I 

 captured in this (Washington) county, twenty years ago. The 

 others were sent to me, one from Long Island, and the other from 

 Rhode Island. Mr. Kirby's specimens were taken in Canada. 



This weevil, though variable in size, is commonly over half an 

 inch in length, and is about two and a half lines broad. It is of 

 a gray color, produced by short whitish hairs upon a black ground. 

 Upon the thorax are three white stripes, more or less distinct, and 

 upon each wing-cover are four white stripes which are interrupted 

 by small black spots. These marks will suffice to distinguish
