Saperda cretata Now m. 

 Spotted appletree borer 



This insect is the more common appletree borer in Michigan, 

 whore it inflicts serious injuries according to Professors Cook. 

 Riley and Osborn. It is probably this insect that Mr L. J. Temp- 

 lin had in mind in 1877 when writing of the appletree borer in 

 the Practical Fanner for Nov. 17. He states that in the "West a 

 " majority of the specimens have a spot on each elytron on the 

 shoulder." and shows that it was quite injurious even at that early 

 date. It also works in the lower limbs of Crataegus, as stated 

 by Dr Hamilton. Professor Osborn has recorded this insect as 

 indicting considerable injury in Iowa. 



Description [pi. 4. rig. 2], Cinnamon brown with a white band 

 on the side of thorax, and a large, oblong white spot twice as 

 long as wide, at middle of each elytron, and another small spot before 

 apex; neither reaching to suture or margin. There is sometimes 

 a minute white spot at middle of base of thorax as well as at the 

 humeral angles. The sides are white; underneath, brown. 



Distribution. This species has been recorded from the follow- 

 ing localities: Paris Out. [E. B. Reed], New York and Penn- 

 sylvania [Hamilton], New Jersey and Ohio [Chittenden] ; Mr 

 Chittenden states that there are specimens of this insect in the 

 United States National Museum from northern Illinois and 

 Texas ; Leng and Hamilton record it from the following locali- 

 ties: Massachusetts, Canada, Michigan, Wisconsin, Iowa, Illinois 

 and Pennsylvania; and Mr "Wenzel informs us that he has re- 

 cently taken it at Philadelphia. Mr Blanchard took it at Tyngs- 

 boro Mass. 



Food plants. This species, in addition to the apple, attacks 

 wild crab apples, and it has been observed on Juneberry 

 [Chittenden],
