COLEOPTERA. 



it as being dark brown, and clothed with very short, rust- 

 yellow, flattened hairs, which are disposed in spots on its 



wing covers. It is nearly 

 three-tenths of an inch long, 

 exclusive of the snout. 



The genus H>/!obinx has 

 the antennae inserted before 

 the middle of the snout, not 

 far from the sides of the 

 mouth. The Pine weevil, 

 Ilt/loliiiis pales Ilerbst, is 

 very destructive to pines, the pitch-pine especially. This 

 deep chestnut colored weevil is very abundant in May and 

 June. It has a line on the thorax, and yellowish white dots 

 scattered over the body, while the thighs are toothed beneath. 

 and the slender cylindrical snout is nearly as long as the tho- 

 rax. The larv;e are found under the bark. In old trees it 

 Imrrows under the bark, its galleries extending irregularly over 

 the inner surface of the bark and in the sap wood. 



The White-pine weevil, Pissodes xlr<>! 

 Peck (Fig. 463; ., larva: />, pup:i). 

 equally destructive with the former, is a 

 smaller beetle, more slender, and oblong 

 oval in form. It is rust-colored brown, 

 with t\vo white dots on the thorax, a 

 white scutellum, and behind the middle 

 of the elytra, which are punctured in 

 rows, is a transverse white line. Harris 

 .states th it its eggs are deposited on the leading shoots of 

 the pine, probably on the outer bark, and the larva when 

 hatched bores into the shoot, and thus distorts the tree for life. 

 The pupa is found just under the bark, the beetles appearing 

 in the autumn, though in much greater numbers in May. 



We have found this insect, in all its stages of growth, 

 under the bark of the white pine the last of April, the 

 larv;e being the most numerous. The larva is white, foot- 

 less, cylindrical, with a pale reddish head. It is .32 of an 

 inch long, and transforms in a cell. The pupa is white, the 

 tip of the abdomen being square, with a sharp spine on each
