PROMINENTS. 113 
The mimicry of the larva has already been mentioned; 
that of the moth is equally interesting. It always rests 
head downwards, with the legs all drawn together, and its 
wings folded round the body, which is stretched out at an 
angle of about 45 degrees, the dull gray coloring of the 
wings with its lichen-green and flesh-colors give the whole a 
perfect resemblance to a piece of rough bark so that the 
deception is perfect. Caterpillar and moth are shown in 
Fig. 112 and in Fig. 113, Plate XIX. 
These caterpillars are also general feeders and occur in 
some numbers on the plum, apple, rose, dogwood, elder, 
wintergreen, blackberry and raspberry. They can not be 
salled very injurious, as they are not common enoughin our 
State. 
THE LONG-HORNED PROMINENT. 
(Schizura ipomezx Doubleday). 
This insect is also not very common in our State, but as 
its larva feeds not alone on oak, maple, birch, etc., but also 
on the blackberry and raspberry, and perhaps on the plum, 
it is best to mention what is known aboutit. The cater- 
pillars vary considerably, but usually they are green, 
speckled with purple. There is also a faint sub-stigmatal 
sulphur-yellow line, most distinct on the thoracic joints, and 
a broad pale sub-dorsal line between which the dorsum is 
pale lilaceous, but thickly mottled with rich purple-brown 
and ferruginous, leaving a narrow dorsal line distinctly 
marked. Two elevated ferruginous warts occur on top of 
joints 4and11. The head is large, dark green, with a dis- 
tinct lateral black and white stripe. The caterpillar differs 
from that of unicornis chiefly by the spine on the front ab- 
dominal segment, which is almost three times as large and 
high and which ends in a deep fork, each tine of which bears 
a stiff truncated spine. When full grown the caterpillar 
makes an earthen cocoon, regular oval in shape, covered
