SPHINX ELSA. 127 



towards base where tliey tire on upper side pale rose. Beneath liead and body white tinged with rose, a 

 dark brown line on sides of thorax, legs brownisii mixed with rosy wliite, tarsi blaek. 



Upper surfaee jiriniaries wdiite tinged on inner two-thirds with rose colour, a blaek jiowdery basal patch 

 extending some distanee'outwards and terminating in scattered black points about the michlle of wing ; also 

 three sonicwliat wa\ed lines or narrow l)ands composed of more or less segregated blaek points or atoms, these 

 lines run more or less ]iarallel 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 blaek points; no indications of a discal 

 spot; fringe white witli blackish at terminations of veins. Secondaries white with black mesial and submar- 

 ginal bands like in Draplferarum, but not as heavy in proportion. 



Under surfiice 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 upj)er side faintly repeated. 



Fkmale. Expands :3 inches. 



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

 less tinged with rosy, the ))atagiae and part towards head being j)ure white, abdomen also as in c?, but the white 

 parts without the ros}- tint. 



Upper surface of all wings pure white exce]it a reddish tint which accompanies the fii-st black 

 band from the base; black bands, etc., much as in d, but more distinct. The wings in this sex are liroader: 

 the primaries less j)ointe<l 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 hne of the c?. Its neai'cst 

 American congenor is Drupi/erarum, and its European of course Liguntri, L., from both of which, as well as 

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

SPHINX HAGENI. Grote.

This species was originally described Trom an example in the Miis. Conjp. Znol. Cambridge, taken liy Boll in Texas. Since then 

 that gentlemen has bred it in some numbers from the larvie. Grote's superficiality was again made painfully evident in his description 

 of this species by placing it in the genus (or sub-genus) Cera(omi'n, Harris, of which the larva Ls distinguished from all others of the 

 Sphingidie, as fiir as I am aware, in the presence of lour liorns, 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, lingeni is nearest to Sphinx iDaremma) Undu- 

 losa, Wlk., and it is almost incredible tliat Grote, who even made some eompiirisons between that species and Ikigeni in his description 

 of tlie latter, could overlook their aflinity. In truth, so close are the two that in a large series of both species, received from B<dl, there 

 are some examples about which it is difSeidt to decide to which species they belong, and the absence of the greenish or olivaceous hue 

 alone makes it a fair proliability that they arc Undulosa, though as a general thing this latter is by far the larger of the two, but it 

 attains a greater size in the New England and Middle .States than it does to the far soutli or west, and tiie 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 .Sphingida' 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 ciosely 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 ilesh coloured, thickly studded with ^mall 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 lo 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 Loudon, Eng., 

 this insect has been a puzzle to American Lepidopterists. In 1S76, Prof. Westwuod 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 Harririi, of which
