rubbish in the same way, and under this imperfect cover 
it changes to a papa or chrysalis 
(Fig. 154), and finally appears in 
the winojed state in the month of 
July of the following year. The 
moth, to which Sir James Edward Smith gave the name 
of Pampinatrix^^ (Plate V. Fig. 4), from its living on the 
shoots of the vine, expands from two and a half to three 
inches, is of an olive -gray color, except the hind wings, 
which are inist-colored, and the fore wind’s and shoulder- 
covers are traversed with olive-crreen bands. 
Among the Sphinges of Massachusetts may be mentioned 
those belonging to the genus Smerinthus^ Avhose tongue is 
very short and scarcely visible, and whose fore wino-s are 
generally scalloped on the outer edge. Their caterpillars 
are rough or granulated, with a stout thorn on the tail, and 
a triangular head, the apex of the triangle corresponding 
to the crown. The blind-eyed Smerinthus (aS'. exccecata^ 
Fig. 155) is fawn-colored, clouded with brown, except 
the hind wings, which are rose-colored in the middle, and 
ornamented with an eye-like black spot having a pale blue 
centre. The caterpillar lives on the apple-tree, but is not
