 III. Sub-Family Lamiin.e. 



The species belonging to this family may usually be distinguished 

 from those of the other sub-families by the vertical head, but there 

 are quite a number belonging to (J erambycinse, which have the 

 face so strongly inclined that care must be taken in using this 

 character. The last joint of the palpi or feelers is cylindrical and 

 pointed. 



The larvae are footless grubs resembling in some respects the grubs 

 of the Buprestians, but are more cylindrical, the indentation is more 

 distinct, and the front segment is not so much larger in proportion to 

 the others. Although there are a number of species found in Illinois 

 which are more or less injurious, we can mention here only a few of 

 the more important, which belong chiefly to the genus Saperda. 



Saperda Candida, Fabr.; (S. bivittata) — Say 



Apple-tree Borer.) 



(The Round-headed 



SapekdaT'candida, Fabr.; (S. bivittata, Say); the Round-headed Apple-tree Borer : —a, larva ; 

 b, pupa; c, beetle. 



This is one of the most injurious borers with which the orchard- 

 ist is troubled, its only rival in this respect being the Flat-headed 

 Apple-tree Borer — (Chrysobothris femorata.) 



It is easily recognized by the following characters : 



It is long and narrow, the length varying from about three-fifths 

 to three-fourths of an inch, the width across the shoulders being 

 about one-fourth the length ; the antenna 3 are nearly as long as the 

 body, slender and tapering ; there are two very distinct white stripes 

 running from the head to the tips of the wing-cases between three 

 rather broader cinamon-brown stripes. These stripes are so distinct 

 and well mavked that they are sufficient of themselves to distinguish 

 the species. 



It makes its appearance in the beetle state in May and June, but, 

 as it remains quiet and hid during the day, and flies at night, it is 

 seldom seen except by those who search for it. During the month of 

 June or the first part of July, according to latitude, the female depos- 

 its her eggs, one in a place, upon the bark of the tree, low down on 

 the trunk or near the ground.
