10. The common orange sawyer. 



Elaphidion inerme Newman. 



In his report on Orange Insects, Mr. H. G. Hubbard says that "the 

 larvae of this beetle are more properly scavengers or pruners, feeding 

 by preference upon dead branches, not only of orange, but nlso of hickory 

 and other hard-wood trees, and confining themselves to the dry and 

 lifeless wood, unless compelled by hunger to enter the living portions 

 of the plant." The female deposits one or two eggs in the dead stubs 

 of orange trees, and presumably of hickory trees.

11. The lurid dicerca. 



Dicerca luridn (Fabricius). 



Order Coleoptera ; family Buprestid^. 



Boring in the trunks and limbsof the pig-nut hickory, aflat- 

 headed grub of a yellowish-white color, changing to a flat- 

 tened, hard-shelled beetle with short slender antennic, of a 

 lurid dull brassy color above, and bright copper beneath, 

 with the wing-covers lengthened into diverging obtuse points. 



Larva.— 0{ a yellowish-white color, very long, narrow, and 

 depressed in form but abruptly widened near the anterior ex- 

 tremity. The head is brownish, small, and sunk in the fore- 

 part of the first segment; the upper jaws are provided with 

 three teeth, and are of a black color; and the autenuse are very 

 short. The segment which receives the head is short and trans- 

 verse ; next to it is a large oval segment, broader than long, 

 and depressed or flattened above and beneath. Behind this, 

 the segments are very much narrowed and become gradually 

 longer; but are still flattened, to the last, which is termin- 

 ated by a rounded tubercle or wart. There are no legs, nor
