INJURIOUS INSECTS 



the insect. But even where the soap preventive is used 

 in the month of May, it is always advisable to examine 

 the trees in the fall, at which time the young worms that 

 hatched through the summer may be generally detected, 

 and easily cut out without injury to the tree. Particular at- 

 tention should also be paid to any tree that has been injured 

 or sun-scalded, as such trees are most liable to be attacked. 



THE FLAT-HEADED APPLE-TREE BORER. 

 (Chrysobothris femorata, Fabr.) 



This borer which is presented in the larva state at 

 figure 95, a, may at once be recognized by it anterior ends 

 being enormously enlarged and 

 flattened. It is paler than the 

 preceding, and makes an entirely 

 different burrow. In consequence 

 of its immensely broad and flat- 

 tened head, it bores a hole of an 

 oval shape, and twice as wide as 

 high. It never acquires much 

 more than half the size of the 

 other species, and is almost al- 

 ways found with its tail curled

is of a greenish-black color, with brassy lines and spots 

 above, the underside appearing like burnished copper. 

 This beetle flies by day instead of by night, and may often 

 be found on different trees basking in the sunshine. It at- 

 tacks not only the Apple, but the Peach, also the Soft Ma- 

 ple, Oak, and is said to attack a variety of other forest 

 trees; though, since the larvae of the family (Bupre&tida), 

 to which it belongs, all bear a striking resemblance to each
