INSECTS INFESTING THE PINE. 



CHAPTER CLX. 



The Pales Weevil. (Cal.) 



{Hylohhia iviloi. — Herbst. ) 



Order, Coleoptera ; Family, Curculionid^. 



[Living beneath the liark of the pine tree; a whitish footless 

 grub, finally transforming into a dark ])rown or black snout- 

 beetle, about four lines long, and marked with numerous 

 whitish spots.] 



Before pupating the larva gnaws a passage to the outside of 

 the bark, but leaves a thin covering to its burrow in which it 

 assumes the pupa form. 



Fig. 234. — Pales Weevil — colors, black, brown 

 and white. 



In due time it is changed to a beetle (Fig. 234) 

 which gnaws through the thin covering of its 

 burrow and makes its escape. I have found the 

 grul), pupa and perfect insect of this species in 

 pine slabs shipped from the mountains, and 

 have found a specimen having a similar appear- 

 ance on pear trees.
