191 FRUIT INSECTS 



wing-covers of this borer (Fig. 185). Although this insect 

 is widely distributed throughout practically the same ter- 

 ritory as its near relative, it has been recorded as injurious 

 only in Iowa and Michigan. Besides injuring apple and wild 

 crab trees, it also attacks J uneberry and thorn. The beetles are 

 said to lay their eggs in the bark in pairs, half an inch or more 

 apart. The grubs of each pair upon hatching then work in 

 opposite directions around the trunk or branch, at first just 

 beneath the bark, and afterwards entering the hard wood. 



The remedial measures suggested for the round-headed borer, 

 Saperda Candida, will also apply to this spotted borer, except 

 that the latter often works in the larger branches as well as the 

 trunk, thus rendering it necessary to extend the protective or 

 preventive treatments to the branches.

The larva of another long-homed beetle {Leptostylus acidif- 

 erus Say) sometimes burrows under the bark of diseased apple 

 trees. The beetle is about J inch in length, and brownish- 

 gray in color. The wing-covers are ornamented with numerous 

 small thorn-like points and are crossed, behind the middle, 

 with a V-shaped band, margined with black. The adults 

 may be found from_ August to September. 



The Flat-headed Apple-tree Borer 



Chrysohothris femorata Fabricius 



This Buprestid beetle is widely distributed throughout the 

 United States and southern Canada. It is often found basking 

 in the sunshine on fallen trees and the warm, sunny sides of 

 the trunks of many kinds of trees, but the shy creature is not 

 easily captured, as it runs rapidly or flies readily when ap-
