79. Li Contk's saw-fly. 
Lophjfrui leeontei Fitch. 
Clusters of dirty yellowish, Mack-spot te<l false caterpillars on the outer branches 
of ornamental pines and firs on lawns, stripping the leaves and disfiguring the 
shrubs. 
Dr. Fitch described under the above name this saw-fly, but did not 
rear it from the larva, though inferring that it was the parent of certain 
false caterpillars, of which he found two broods on "pines, particularly 
those set in our yards for ornaments, stripping the limbs which they 
invade of their leaves." He further says : 
When nearly mature these worms are so large that the end of a single leaf of the 
pine probably furnishes them a very insufficient mouthful, hence two worms often 
unite, standing face to face, and thus hold the five leaves which grow from each 
sheath on the white pine pressed together in a bundle as they eat them, commencing 
at the tip and gradually stepping backwards as the leaves become shorter. It is 
only the old leaves of the previous year's growth which these worms consume, 
never touching the new ones at the outer end of the limb; hence they injure 
the tree much less than they would were they to strip the limbs they invade 
of the whole of their foliage. At least two broods of these worms appear annu- 
ally, the one yi July, the other in September and October, the latter often 
remaining on the trees after frosty nights have occurred. Having finished feeding, 
they leave the tree and inclose themselves in cocoons under fallen leaves or other 
shelter on the surface of the ground, in which they remain during their pupa state. 
The female. — Length, 0.33 inch to the tip of the abdomen, and 0.48 inch to the end 
of the wings. It may at once be distinguished from all our other described species by 
the joints of its antenna), which are twenty-one in number. It is shining dull, tawny 
yellow, with the antenna) black, and also the abdumen and base of the thorax. The 
under side is paler yellow, with two broad black stripes on the abdomen. The wings 
are smoky hyaline, their veins black. Captured the middle of May. (Fitch.) 
Eiley states that this saw-fly has been found feeding on the Scotch and 
Austrian pines in Xew Jersey. The larva he describes as an inch long, 
dirty or yellowish white, with dorsal black marks wider before than 
behind, and usually broken transversely in the full-grown individuals. 
They are further apart than in L. abbotii. The lateral spots are some- 
what square, with an additional row of smaller black marks below 
them, and the last segmeut is entirely black above. 
The antennae of the male fly are twenty-one jointed, and have on one 
side seventeen large and on the other seventeen small branches, there 
being eighteen on one side and fifteen ou the other in L. abbotii. The 
female may at once be distinguished from L. abbotii by her abdomen 
being jet black above, with a small brown patch at the end and a trans- 
verse line of the same color just below the thorax. 
Remedy. — These saw-flies, living as they do,iu societies in large masses 
of coarse castings like sawdust, are easily detected by the eye, and can 
readily be removed by hand, especially in the case of ornameu tal shrubs. 
Also shower and jar the trees.
