266 HYBRIDS OF SPHINGID^. By Dr. P. Denso. 



X hippophais $ bears a striking resemblance to that of euphorbiae and feeds on Euphorbia, Avhile of the only 

 known larva of pauli we know that it was found on Hippophae rhamnoides. 



harmuthi. C. hybr. harmuthi Kordesch (43 a) (Celerio euphorbiae euphorbiae L. ^ x Pergesa elpenor elpenor L. $). 



(Postal border broad and dark olive-green , merging into red apically. The oblique band, which has usually 

 a very distinctly convex inner edge in elpenor, is distinctly concave in its second tliird owing to being very broad 

 at the hind margin. The light olive-green elpetior-Mne is very broad, dark olive-green, and somewhat diffuse 

 distall3^ This line runs parallel with the proximal edge of the oblique band and corresponds to the atavistic 

 line of the species of Celerio, which line begins at the outer costal spot and runs to the hind margin of the fore- 

 wing almost parallel with the inner edge of the oblicpie band. The area between it and the oblique band which 

 in elpenor is mauve-pink is light pink. The lower black basal spot is only faintly indicated, distally of it there 

 is a deep red patch reaching as far as the faintly indicated median costal spot. The black discocellular 

 dot is usually present. The hiiidwing is pink, with a very broad black base and an olive-green diffuse mar- 

 ginal band. The anal spot, which is bright white in euphorbiae, and not present in elpenor, is slightl}' indicated and 

 light pink, the marginal band is light pink, thorax and abdomen dark olive-green, the patagia are slightly mar- 

 gined with a reddish tint. The underside of the wings reddish, pA the costal margin in the second third near 

 the apex a light olive-greei; spot, from which two parallel blackish green lines run to the hind margin, there 

 being two corresponding olive-green lines on the hindwing. In ab. griseofasciata Kysela the patch proximal to 

 the oblique band of the forewing, usually pink, is grey and mueli broader. Tlie hindwing bears a strongly 

 marked black marginal band. ■ — As yet apparently only obtained in captivity. 



galiphor- Q. hybr. galiphorbiae Denso (43 a, c) (Celerio gallii gallii Rott. ^ x Celerio euphorbiae euphorbiae L. $). 



■ Compared with the inverse cross hyhv. kindervateri, galiphorbiae inclines more towards gallii. The basal accessory 

 spot is closely united with the broad olive-green costal margui. The olive-green oblique band bears the con- 

 cavity tjfpical of gallii, but in a lesser degree. The lower black basal spot is more strongly developed than 

 in kindervateri. The hindwing is more yellowish red, which gets darker towards the anal angle. The yellowish 

 underside of the wings is very like that of gallii. The white dorsal line is nearly always distinctly present. The 

 philewphor- pulvillus is small. The moth named lnd>r. phileuphorbia by Mutzel and considered to be hybr. gallii x 

 ***"■ euphorbiae is distinguished from galipJiorbiae especially by the very characteristic oblique line; with respect 

 to its course it stands between gallii and galiphorbiae. The pulvillus is large, as in gallii. The white dorsal 

 line is absent. ■ — The larvae of phileuphorbiae were remarkably like those of gallii, but fed on Euphorbia. The 

 larvae of galiphorbiae are so like those of euphorbiae that they might be mistaken for them; phileuphorbiae 

 seems to be a secondary hybrid. The moths of galiphorbiae, only four being as yet known, are distinguished 

 by their unusual size. Their pupae lie over for years and only emerge if some specially strong factor comes 

 into play. The full-grown larva often only bears one row of lateral spots, the upper row being usually more 

 reddish than in euphorbiae, and on the whole more closely resembles the larva of gallii. ■ — Often obtanied in 

 captivity, occurrence in nature doubtful; philetiphorbiae was found in nature. 



galitanica. C. hybr. galitanica Denso (Celerio gallii gallii Rett. ^ x Celerio euphorbiae mauretanica Stgr. $). Distinguished 



from hybr. galiphorbiae by the light straw-coloured ground-colour being more broadly extended apicad at the 

 costal margin, the olive-green oblique band is also very steep before the hind margin and is deeply concave 

 in its last third. The red colour of the hindwing stronger, the black submarginal band is narrower and 

 more irregular, the marginal area broader. Antennae lighter. Full-grown larva very light in colour on account 

 of the very large striated spots. Subdorsal spots peach-red, the second row, when present, only consists of 

 small spots. Pupa similar to that of gallii. — Only bred in captivity. 

 carolae. f, ijybr. carolae Kysela (4:1 b) (Celerio gallii gallii Rott. ^ x Celerio vespertilio Esp. ?). According 



to the original description this hybrid has the same scheme of markmgs as gallii, but somewhat diffuse and dark 

 greyish olive on a grey ground. Tiie hindwing has a black basal area corresponding to that of gallii and a 

 uniformly red band, which is bounded by a grey submarginal band. Tlie anal spot is distinct, white. The 

 antennae resemble those of gallii. The greyish olive- abdomen bears two black-white lateral spots, the seg- 

 mental incision are edged with white, and there is an only faintly indicated dorsal line. Larva black- 

 brown, without subdorsal line, spots pale pink, small white striated spots. Horn short. On the whole it 

 resembles the larva of gallii. — As yet only obtained in captivity. 

 kramlingeri. c. hybr. kramlingeri Pernold (C. vespertilio Esp. ^ x C. gallii gallii Rott. ?). Forewing extraordinarily 



dark, but the sfn/Zu'-markings distinctly recognisable. The oblique band not projecting as far basad at the 

 hind margin as in gallii. Hindwing with carmuie median band, which is more uniformly coloured than in gallii, 

 being usually only very slightly lighter at the costal margui. Antennae white or brownish black with white 

 apex. Thorax and abdomen blackish olive-grey. Dorsal line not present. Underside of wings recalling 

 gallii, very variable.

neri. Qq^^^} margin very broadly suffused with olive-green. At the apex a yellowish pink lighter patch. The 



lower black basal spot small. The basal area, which is light pink in harmuthi, is smaller, grey. The ata-
