INSECTS AFFECTING THE ORANGE. 



covered above with minute horny asperities, which are pressed against 

 the walls of the burrow, and serve to hold the body firmly in place while 

 the jaws are forced into the wood. The full-grown larva is about one 

 inch in length. 



The pupa is formed in the gallery, in a rude cell made by pushing 

 aside the chips with which the larva stops up all the approaches to its 

 burrow. 



The perfect insect has a long, cylindrical body with rather roughly 

 pitted surface j the color is dark brown, dusted densely beneath, but

irregularly above, with fine ash-gray hairs ; the antennae are not longer 

 than the body. The length varies from ll mm to 15 mm (-*fo to^- inch) ; 

 the males are smaller than the females. 



Fig. 48 illustrates, in all its stages, Elapliidion parallelum Newm., a 

 closely allied species, which lives in northern fruit-trees, and has habits 



similar to the Orange Sawyer. In the 

 figure, a represents the larva 5 6, the 

 pupa in its ^ell ; c, the perfect insect ; 

 dj the head; e,f, and #, the mouth parts; 

 and 7i, the antenna of the larva, enlarged; 

 i and^' show details of the antennaB and 

 tip of the wing-cases, respectively, in 

 the imago ; fc, the end of the twig which 

 contains the borer. 



The Iarva3 of this beetle are more prop- 

 erly scavengers or pruners, feeding by 

 preference upon dead branches, not only 

 of Orange, but also of Hickory and other hard-wood trees, and confin- 

 ing themselves to the dry and lifeless wood, unless compelled by hunger 

 to enter the living portions of the plant.

 beetle ; d, e, /, <j, h, head and mouth parts
