in. broad, nearly plane dorsally, and quite convex ventrally. Color, 

 chesnut brown, on the posterior margins of the segments dark brown. 

 Head-case sub-quadrangular as seen from above, and quite prominent. 

 Tongue-case dark brown, 1.25 in. long in its exterior curve, projecting 

 beyond the head-case, rising from .15 to .18 in. above the breast, regu- 

 larly ridged transversely and bicarinated medially, terminating between 

 the tips of the antennae-cases in a conspicuous bulb; the buried portion 

 extending just beyond the tips of the wing-cases. Third segment with 

 a central dark brown fold reflected posteriorly. The fourth, fifth and 

 sixth segments with dorsal transverse wrinkles. Abdominal segments 

 with numerous impressed points, except on their anterior margin, where 

 they are conspicuously indented. Anal segment terminating in a short,

Unlike most of the Sphinges, this species is very easily reared. I 

 know of no parasite which attacks the larva. When mature, if merely 

 inclosed in a box, without providing it with earth, it undergoes its pupal 

 transformation, and with very little care, beyond simple exclusion from 

 the light, seldom fails of giving out the imago in due time. Very rarely, 

 its final transformation is delayed until the second summer. 



Sphinx cingulata Fab, 



The larva of this species presents a great number of varieties, which 

 reduce themselves to two principal types — those of a green ground, and 

 those of a brown. Of the former there are found three varieties : 



The first variehj^ which is that which is met with most ordinarily, is 

 of a dark green, with seven oblique black bands on the sides, which 

 terminate on the back in two longitudinal stripes of the same color, often 

 indistinctly marked, and always interrupted at the incisures. These 

 bands, which commence on the fourth segment, and of which the last 

 terminates in the horn, are lightly bordered with white inferiorly. On 

 the dorsum of third and fourth segments there are two black spots, four 

 very small on the tenth, and two very large placed laterally on the inci- 

 sure of the first and second segments. Head green, slightly yellowish, 

 with five black perpendicular lines, of which the middle one is divided in 

 two inferiorly. Legs blackish, and prolegs green, with the crown gray. 

 Caudal horn smooth, yellow or ferruginous, with a black tip. The 

 stigmata are covered by some orbicular black spots. The caudal shield 

 is orange-yellow.
