Four c^'s, 12 $'s bred from larvae of Lophyrus Abbotii. 



REMEDIES. 



As evergreens suffer more from defoliation than deciduous trees, 

 it is essential, during the j)roper season, to scan them very closely 

 every few days where this insect is known to prevail. When the 

 worms are noticed, a syringing of hellebore water, or a dusting of 

 fresh air-slacked lime, while the tree is bedewed, will destrov them. 

 Care should be taken to prevent their injuries by clearing the ground 

 around the trees late in the Fall, and burning the fallen needles and 

 rubbish, with such cocoons as may be among them. 



DESCRIPTIVE. 



Lophyrus Abbotii ; — Larva — Average length 0.80 inch, though many will measure 

 about an inch. A soft, dingy, white worm, having often a greenish or bluish line 

 superiorly. On all joints but the first, which is entirely white, two oblong square 

 black spots along the back, and another somewhat rounder spot each side. These 

 become somewhat diffuse on the three latter joints, forming on the last a single black 

 patch. Three black thoracic legs, fourteen abdominal, and two caudal prolegs. 

 Thoracic joints largest ; the three last, smallest and tapering. Some are marked very 

 regularly, while in others the white space on the back between the spots on joints 5, 6, 

 7 and 8, is much wider than between the others. This is probably sexual difference, 

 since those thus marked are shorter, thicker, and of a yellower white than those regu- 

 larly marked. After each change of skin the head is at first white like the rest of the 

 body, with the usual eye-spots black. No markings while young. 



LE CONTE'S PINE WORM— Zo^Ay/'ws LeContei Fitch. 



[Ord. Hymenoi'tera ; Fam. Tenthredinid.e] 



Abbott's Fine Worm shows great preference for the White Pine 

 and is seldom found on any other. It is, moreover, the most common 

 and destructive species of the genus in our part of the country. La- 

 Conte's Pine Worm is, on the contrary, a more general feeder and pre- 

 fers the coarse-leaved pines, such as the Austrian, Scotch and Pitch.
