to strip the limbs they invade of the whole of their foliage. 
At least two broods of these worms appear annually, the one 
in 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 them¬ 
selves in cocoons under fallen leaves or other shelter on the 
surface of the ground, in which they remain during their pupa 
state. 
In addition to the Lophyrus described by Dr. Harris, four 
other North American species were described by the late Dr. 
Leach, the preparatory states of which are not known, but 
they doubtless feed upon the pine or fir as do all the species of 
this genus whose habits have been observed. I therefore sub¬ 
join a brief description of each of these species, as they may 
perhaps prove to be inhabitants of New-York. 
A sixth species, larger than either of the others, is known to 
me. This, its size indicates, may very probably be the parent 
of the worms which I have described above. I name it in 
honor of our distinguished American entomologist, whose labors 
have added so vastly to our knowledge of the Coleopterous in¬ 
sects of our country. 
Leconte’s Lophyrus measures 0.38 to the tip of the abdomen 
and 0.48 to the end of the wings in the female, and it may at 
once be distinguished from all our other described species by 
the joints of its antennae, which are twenty-one in number. It 
is shining dull tawny yellow, with the antennae black, and also 
the abdomen 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. 
274. American saw-fly, Lophyrus jfmericanus, Leach. 
The female 0.42 long, clay colored with the abdomen darker, 
the antennae black, with nineteen joints, the thorax spotted 
with black, and the wings hyaline with the forward pair slightly 
yellowish at least towards the base.
