in irregular transverse rows. An oblique cream-colored 
lateral band, bordered below with darker green, and most 
distinct on the middle segments, connects with a cream- 
colored sub-dorsal line, which is bordered above with darker 
green, and which extends from the head to the horn at the 
tail. There are five and often six somewhat pale yellow 
triangular patches along the back, each containing a 
lozenge-shaped lilac-colored spot. The head is small, with 
yellow granulations, and four perpendicular lines, and the 
spiracles or breathing-holes are orange-brown. The cater- 
pillars vary considerably in coloration, especially those of 
the second brood, where the green is often replaced by a 
delicate reddish-pink, with markings of darker shades of red 
and brown. When full grown the caterpillar descends from 
the vine, and among old leaves or any other rubbish lying 
on the ground it forms a mesh 
of strong brown silk, within 
which it changes toa pupa (Fig. 
45), which is ofa pale brown col-

The moths of the first brood appear during May; those 
of the second late in July. The insect passes the winter in 
the pupal state. 
The best method to dispose of these pestsis to pick them 
off the vines, and as the worms are readily detected by the 
ravages they cause this remedy is very simple. Though fre- 
quently very numerous, their num- 
bers are kept in check by several 
parasitic insects. It is not uncom- 
mon to see one of these caterpillars
