width across its wings, which are of a dusky rust color and 
without spots above, paler grayish beneath, the fore ones with 
a dislocated black band beyond the middle, edged on its hind 
side with snow white, and beyond this a row of black crescents, 
each with a white spot in its concavity, and the hind wings simi¬ 
larly but more complexly variegated. 
Boisduval says, “ This insect lives in Georgia and Florida, on 
several species of pine, and is very rare and seldom seen in col¬ 
lections.” It, however, is a common species in the State of New- 
York, in all our forests where pine trees abound, coming out 
with the first warm days of spring, before collectors are much 
abroad in search of insects, and continuing but a short time. 
273. Leconte’s saw-fly, Lophyrus Lecontei, new species. (Hymcnoptcra. 
Tenthredinidse.) 
Clusters of cylindrical, slightly tapering worms with twenty- 
two legs may occasionally be noticed on pines, particularly those 
6et in our yards for ornament, stripping the limbs which they in¬ 
vade of their leaves. They are the progeny of different species 
of saw-flies pertaining to the genus Laphyrus. One of these, 
which occurs upon the fir as well as on the pine, the transfor¬ 
mations of which have been traced by Dr. Harris, will be found 
described on a succeeding page with the other insects of the fir 
and spruce. Another kind which 1 have noticed at different times, 
but have not yet had an opportunity to rear to its perfect state, 
grows to an inch in length and is white with two rows of oblong 
square black spots along its back and a row of broader square 
ones along eacli side, with the head and the six anterior legs 
also black. 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, stand¬ 
ing 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 con¬ 
sume, never touching the new ones at the outer end of the limb, 
hence they injure the tree much less than they would were they
