SPHINX ELSA.

towards base where they are on upper side pale rose. Beneath head and body white tinged with rose, a 
dark brown line on sides of thorax, legs brownish mixed with rosy white, tarsi black. 
Upper surface primaries white tinged on inner two-thirds with rose colour, a black powdery basal patch 
extending some distance outwards and terminating in scattered black points about the middle of wing; also 
three somewhat waved lines or narrow bands composed of more or less segregated black points or atoms, these 
lines run more or less parallel with the exterior margin, but all unite into one at the apex where it is most dis- 
tinctly defined. Whole wing loosely scattered more or less with minute black points; no indications of adiscal 
spot; fringe white with blackish at terminations of veins. Secondaries white with black mesial and submar- 
ginal bands like in Drupiferarum, but not as heavy in proportion. 
Under surface primaries white tinged very faintly with rose, powdered with fine black points, two parallel 
submarginal lines composed of loose black atoms and converging into one better defined line at the apex. Sec- 
ondaries white tinged with pale rose and with the black bands of upper side faintly repeated. 
Female. Expands 3 inches. 
Head white, antennae black with white tips, thorax much as in d but with much more black on back and 
less tinged with rosy, the patagiae and part towards head being pure white, abdomen also as in d, but the white 
parts without the rosy tint. 
Uppes surface of all wings pure white except a reddish tint which accompanies the first black 
band from the base ; black bands, etc., much as in d, but more distinct. The wings in this sex are broader ; 
the primaries less pointed at the apex and more rounded on the costal margin, and the whole insect is, ex- 
cept in the two points embraced in above description, devoid of the lively roseate hue of the d. Its nearest 
American congener is Drupiferarum, and its European of course IAgustri, L., from both of which, as well as 
from all other species of known Sphingidse, as far as I am aware, it differs in its white colour.

SPHINX HAGENI. Grote.

(PLATE XIV, FIG. G d-) 
This species was originally described from an example in the Mus. Comp. Zool. Cambridge, taken by Boll in Texas. Since then 
that gentlemen has bred it in some numbers from the larva?. Grote’s superficiality was again made painfully evident in li is description 
of this species by placing it in the genus (or sub-genus) Ceratomia, Harris, of which the larva is distinguished from all others of the 
Sphingidse, as far as I am aware, in the presence of four horns, two on the back of the second segment and two on the third, from which 
peculiarity Dr. Harris named his genus as well as the only species in it.* The fact is, Hageni is nearest to Sphinx ( Daremma ) TJndu- 
losa, Wlk., and it is almost incredible that Grote, who even made some comparisons between that species and Hageni in his description 
of the latter, could overlook their affinity. In truth, so close are the two that in a large series of both species, received from Boll, there 
are some examples about which it is difficult to decide to which species they belong, and the absence of the greenish or olivaceous hue 
alone makes it a fair probability that they are TJndulosa, though as a general thing this latter is by far the larger of the two, but it 
attains a greater size in the Xew England and Middle States than it does to the far south or west, and the eastern examples are 
lighter coloured. 
The larva of Sphinx Hageni, when full grown, is about 2£ to 3 inches in length. Generally pale apple green, but occa- 
sionally it occurs of yellowish green with darker streaks, like most of the larva of the Sphingidse it varies somewhat in colour, but 
the apple green is the prevailing hue. The body, all over the back and sides, is covered with whitish points arranged transversely in 
regular rows; head very closely covered with white points not arranged with any regularity ; on the sides are diagonal white lines, 
shaded with rose red on the upper edge, this red shading being darkest in the middle. Spiracles surrounded with brown, which is 
further encircled with yellow. Caudal horn flesh coloured, thickly studded with small raised points. Feet rose red ; prolegs pale 
reddish. Undergoes its transformation in the ground. For the above description, accompanied by a faithful drawing, 1 am under 
obligations to Mr. Boll, who was the discoverer of the species.

Ever since its description by the late Mr. Walker front a unique, at that time in the collection of Mr. Saunders of London, Eng,, 
this insect has been a puzzle to American Lepidopterists. In 1875, Prof. Westwood made for me an accurate coloured figure from the 
type, which latter is now in the Hopeian coll, of Oxford University. The differences between this figure and Sphinx Harrisii, of which
