SPHINX ELSA. 127 



ttiwards Ikisc where tliey are kii ii|)]iei' side pale rose. Jienealli head ajid hddv white linked with rose, a 

 (hirk hfowii line on sides of tliorax, h'<rs brownish mixed witli rosy white, tarsi hhiek. 



l'l)j)er surface primaries white tinijed on inner two-tliirds witli rose cokmr, a Macic j)owdery liasal patch 

 oxteiidinji some distance outwards and terniinatino; in scattered i>hiek points about the middle of wing ; also 

 tliree soniewliat waved lines or narrow bands composed of mort' or less segrejiated black points or atoms, these 

 lines run more or less parallel with the exterioi- maro'in, but all unite into out; at the apex where it is most dis- 

 tinctly detiucd. M'liole wiuii' loosely scattered more or less with minute black |ioints; no indi(tations of a diseal 

 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 projiortiou. 



Tender surface primaries while tinged very i'aintly with rose, powdered with tine black points, two parallel 

 submargiual lines composed of loose black atoms and converging into one better defined line at the apex. Sec- 

 ondarit's white tinged with pale rose and with the black bands of upper side faintly repeated. 



Female. Expands o inches. 



Head white, antennae black with white tips, thorax much as in c? but with aiuch more black on back and 

 less tinged with ro.sy, the ])atagiae and part towards head being pure white, abdomen also as in d', but tlie white 

 parts without the rosy tint. 



U[)pcr surface of all wings jiure white excejit a reddish tint which accompanies the first black 

 band from the base; black bauds, etc., much as in c?, l>ut more distinct. The wings in this sex are bi'oader : 

 the primaries less jiointed 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 c?. Its nearest 

 American congenor is Drupiferarum, and its European of course Ligustri, L., from both of which, as well as 

 from all otlier species of known Sphingidfe, as far as I am aware, it differs in its white colour.

SPHINX HAGENI. Grote.

This species was origimilly descriljed from an example in the Mus. Coinp. Zool. Cambridge, taken liy 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 his description 

 of this .species by placing it in the genus (or sub-genus) Ceralomia, Harris, of which the larva is distinguished from all others of the 

 Sphingid.'e, as far as I am aware, in the presence of tour 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) Undu- 

 losa, Wlk., and it is ahno.st 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 clo.se 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 aj-e Undulosa, though as a general thing this latter is by I'ar the larger of the two, but it i 

 attains a greater size in the New England and Middle States than it does to the far south or west, and the eastern examples are 

 lighter coloured. 



Tiie larva of Sphivx Hageni, when full grown, is about 2J 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 Sphingid* 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 email raised points. Feet rose red; prolegs pale 

 reddish. Undergoes its transformation in the ground. For the above description, accompanied by a faithful drawing, I am under 

 obligations to Mr. Boll, who was the discoverer of the species.

Ever since its description by the late Mr. Walker from a unique, at that time in the collection of Mr. Saunders of London, Eng., 

 this insect has been a puzzle to American Lepidopterists. In 18TO, Prof. Westwood made for me an accurate coloured figure from the 

 type, which latter is now in the Hopeian coll. of Oxford University. The diflerences between this figure and Sphinx Harririi, of which
