dal part, of recumbent hairs. The wings are dusky gray, 
crossed by white lines as shown in the figure. The figure 
represents the male ; the female is much larger. The moths 
are found in August and September. The larva feeds upon 
the leaves of apple, poplar, and syringa. Its body is bluish 
gray, with many faint longitudinal lines; and across the back 
of the last thoracic segment there is a narrow velvety-black 
band. The larva reaches maturity during July. The cocoon 
is brownish gray, and is usually attached to one of the 
branches of the tree on which the larva has fed. 
The second species of this genus is known as the Larch 
Lappet, Tolype laricis (T. lar'i-cis). This is a smaller species, 
the females being about the size of the male of the preced¬ 
ing species, and the males expanding only about one and 
one fourth inches. The wings of the females are marked 
much like those of T. velleda , except that the basal two 
thirds of the front wings are much lighter, and the dark 
band on the outer third is narrower and much darker than 
the other dark bands. The males are bluish black, with the 
markings indistinct. The larva feeds upon the larch. When 
mature it is of a dull brown color and less than one and one 
half inches in length. When extended the front of the first 
thoracic segment is pale green, and the incision between 
the second and third is shining black. The larva matures 
during July. The cocoon is ash-gray, flattened and moulded 
to the limb to which it is attached, and partially surround¬ 
ing it. The moths appear in August or September. The 
winter is passed in the egg state. 
The genus Phyllodesma includes 
three Californian and two Eastern 
species. The more common one of 
the latter is the American Lappet, 
P. americana (Fig. 444). The moth 
is reddish brown, with the inner angle FlG . 444 
of the front wings and the costal 
margin of the hind wings deeply notched. Beyond the mid
