are, however, never provided with stings. While at rest 
many of the caterpillars assume a very peculiar attitude, 
supposed to resemble the Egyptian Sphinx, hence their scien- 
tific name Sphingide. 
THE THYSBE CLEAR-WING. 
(Hemaris thyshe Fab.)._ 
This beautiful insect is not as common as the closely 
related Bumble-bee Hawk-moth (H. diftinis Bdv.), the 
larva of which frequently strips all the foliage from our 
ornamental waxberry plants and honeysuckles. Both moths 
fly during the day and resemble very closely the common 
bumble-bees, both in size and general appearance. The 
wings of thysbe, which expand nearly two inches, are trans- 
parent, and crossed by dark brown veins. The fore-wings 
have a narrow costal border, a wide outer border dentate 
inwardly on the inter-spaces, and a basal patch extending 
along the hinder margin, of a dark, reddish-brown color, 
and overlaid on the basal portion with olive-green hairs. 
This species is readily distinguished from our other species, 
by a line of scales dividing the discal cell lengthwise. The 
hind-wings are bordered all around, narrowly on the costa, 
more widely on the outer margin, with dark, reddish-brown, 
while the hinder margin and base of the wing have a very 
wide border of rusty red. 
The trim-looking caterpillar, nearly one inch and three- 
fourths in length, tapering towards the head, is of a pea- 
green color, granulated, with dark breathing-pores; a 
pinkish stripe extends along the middle of the back, bord- 
ered on each side with a whitish line, which ends in front. of 
the caudal horn. A white or vellowish line runs along each 
side from the second segment to the base of the horn, which 
is curved, light-blue, tipped with yellow, granulated with 
white on the sides, and black in front.
