easily recognized. So are the Lady-birds or Lady-bug beetles, the 

 Lace-wing flies and Syrphus flies that devour such a vast number of 

 plant lice and scale insects. Mantes and Wasps also render effective 

 service in the same line. These should be familiar to every fruit- 

 grower, in order that they may in all cases be protected. 



It is requested in conclusion, that any member of the Horticul- 

 tural society, or any person who may read these lines, whose fields, 

 orchards or gardens are attacked by insects unknown to him, and who 

 desires a remedy for the same, will send specimens securely packed in 

 tin or wooden boxes, and accompanied by a description of the injuries 

 done, to the writer, who will be glad to give all possible information.

The Buffalo Tree-hopper fCeresa hubalus,¥a,hT.) — The accompany- 

 ing cut graphically depicts a series of peculiar scars on the young 

 wood of apple-trees, with which many of our orchardists and nur- 

 serymen are only too familiar. It 

 represents the work of the small 

 jumping insect named above, a spe- 

 cies of the Whole-winged division 

 (Homoptera) of the True bugs. 



It has been known in collections 

 for more than 100 years, but has 

 only recently taken rank as an im- 

 portant pest of the orchard, and, 

 while it occurs in all parts of the 

 United States and Canada, its at- 

 tacks are peculiarly local, being 

 commonly restricted to a single 

 neighborhood or to a single orchard 

 in that neighborhood. 



The perfect insect, the females of 

 which do the cutting, is of a some- 

 what humped-back, angular form, in 

 shape not unlike a small and elon- 

 cLMAHu-rr. gated beech-nut. The color is a 



Scarred twig of apple with a, eggs natural size; b, =
