170 OWLET-MOTHS. 
stigmata and a broad, white, lateral line are also seen. 
The under side is light green. All the piliferous warts are 
prominent, black, and bear a short fine hair. As soon as 
mature, which takes place about the middle of May, the 
larvee enter the ground in which they pupate. Some of the 
moths issue from the last of September to the early part of 
November, and seek shelter under loose bark and other suit- 
able places; other pupz remain in the ground until the next 
spring. 
The moths are rather uniformly brown with a few more 
or less distinct wavy lines of gray or grayish-white. Most 
of them have in the middle of the fore-wings a perfectly 
white spot, which is, however, in some cases colored very 
lightly with brownish. It is shown in Fig. 170%, Plate 
XXIII. 
A number of other species of the genus Scopelosoma fly 
at the same time; they have identical habits and their cater- 
pillars are all very similar. They are very general feeders, 
and as they hatch in most cases before there are any leaves 
they attack the leaf-buds of oak, cherry, apple, raspberry 
and blackberry. If numerous they can cause some damage. 
A single application of London purple will prevent’ any 
further injury. 
THE ASH-GRAY PINION. 
(Xvlina antennata Walk.). 
The caterpillars of this moth are also very general feed- 
ers, but as they have the bad habit of boring into young 
apples and of eating the foliage of that tree, of the hickory 
and other trees, it is best to describe them in this place. As 
far as the habits of this insect are concerned they are very 
similar to those of the one just given. The moths appear 
also very late in the year and quite early in the following 
one, having been captured in large numbers in April. The
