188 THE GEAPE CTTLTUEIST. 



they purport to be, as some are easily destroyed by Tery 

 simple means, but there is no universal remedy the appli- 

 cation of which is at all practicable. A material that "woiild

 while it would be vei-y diiBcuIt to find anything so povr- 

 ei'ful that it would kill all kinds of insects, and at the same 

 time not injure the plants upon which they were found. 



The following list is not supposed to contain aD, or any 

 considerable portion of the insects that are injurious to the 

 grape, but only those that are best known. 



There are often several species nearly related to each 

 other, and from a description of one of the number 

 the others may be readily recognized. Every vine- 

 yardist should make himself acquainted with the vari- 

 ous insects that infest the vine, and thereby be enabled to 

 more successfully check their ravages. 



There are several excellent works on entomology that 

 are within the reach of those who desire information on 

 this subject; the best among them is Harris' "Insects In- 

 jurious to Vegetation," a new edition of which has lately 

 been issued by Crosby & Mchols, Boston — edited by 

 Charles L. Flint. To this work I am mainly indebted for 

 many of the illustrations and descriptions I have given. 



ROSE CHAFER, or Rose Bug. — Mdolontha subspinosa, 



— ^Fig. 67 — of Fabricus, by whom it was first 

 described; it belongs to the modern genus 

 Maarodactylus of Latreille. 



This beetle measures seven- twentieths of an

 and behind, and is entirely covered with very short and close 

 ashen-yellow down ; the thorax is long and narrow, angularly 

 widenedin the middle of each side, which suggested the name 

 subspinosa, or somewhat spined ; the legs are slender, and 

 of a pale red color ; the joints of the feet are tipped with
