BUTTERNUT. LEAVES. 
Both species are very similar to the Tingis rhoniboptcra described 
in Fieber’s excellent monograph of this family, and figured, plate 
8 fig. 37, but that has a spot on the middle of the outer margin 
of the wing covers and their tips much less discolored with brown 
than in our insects. 
104. Butternut wooly-WORM, Selandria ? Juglandis, new species. (Ily- 
nienoptora. Tenthredinidse.) 
A worm remarkable for being enyeloped and wholly hid in a 
thick coating of snow-white flocculent meal which falls off with 
the slightest touch, resides in companies on the under sides of the 
leaves, feeding upon them, in the month of July. It is of a cy¬ 
lindrical form, a very little tapering from its head to its tip, and 
has ten pairs of dull pale yellow feet, its body being of a blackish 
color and its head pale yellow and polished, with a large black 
dot upon each side. It has numerous transverse impressed lines 
and a groove on the middle of its back its whole length. The 
individuals I have examined were nearly half an inch in length. 
My attempts to rear them have proved unsuccessful. In one in¬ 
stance the leaf on which they were found was pinned to a leaf of 
a butternut growing in my yard, without disturbing them, but 
they refused to move from their original abode and perished as 
the leaf withered. They are evidently a species of saw-fly, per¬ 
taining there is scarcely a doubt to the genus Selandria and the 
sub-genus Enocampa , thus named from its larva; being covered 
with pruinose woolly matter. 
The Hickory tussock-moth No. 183, occurs about as frequently 
on the butternut as on the walnut, and two other caterpillars be¬ 
longing to the same genus but which are not yet known to us in 
their perfect state are also common upon this tree. Other cater¬ 
pillars and worms which have been observed feeding upon the 
leaves of the butternut are the larvae of 
The White miller No. 125; 
The Fall web-worm No. 88; 
The Cecropia emperor moth No. 33; 
The Polyphemus moth No. 181; and 
The Black-walnut sphinx No. 186.
