and tipped and banded with brown as shown In Figure 
410. The hind wings are deep carmine at the middle, and 
are bordered with pale tan or gray. Near the anal angle 
there is a large black spot in which there is a pair of blue 
spots, which suggested the name geminatus . The larva 
feeds upon the leaves of apple, plum, elm, ash, and willow. 
Harris’s Sphinx, Ellema harrisii (El-le'ma har-ris'i-i).—> 
This sphinx has interested us chiefly on account of the 
habits and markings of its larva (Fig. 411). It feeds upon 
the foliage of pine, and is colored with 
alternating green and white longitudi¬ 
nal strips; the dorsal stripe is green 
spotted with red. It has a way of 
hanging head dowrfward in a pine tas¬ 
sel that conceals it entirely from the 
sight of all but very sharp eyes, its 
stripes giving a close resemblance to 
a bunch of pine leaves. The moth ex¬ 
pands about two inches ; it is gray with 
the fore wings marked by several series 
of small brown spots. 
The Pen marked Sphinx, Sphinx 
chcrsis (Sphinx cher'sis).—This moth is 
of an almost evenly distributed ashy- 
gray color. This sombre color is relieved 
somewhat by a black band on each 
side of the abdomen, marked with four 
or five white transverse bars; by two 
dark brown, smoky bands which cross 
the hind wings; and by a series of black 
dashes on the fore wings, one in each 
cell between the apex of the wing and the anal vein. These 
dashes appear as if drawn casually with a pen. The larva (Fig. 
408) is not uncommon upon ash and lilac ; it is greenish 
or bluish white above, and darker below ; there are seven 
oblique yellow bands on the sides of the body, each edged
