doubts as to whether it is anything but a form of Thaumas vespertilio. 

 His argument appears to support us in this conclusion. 



6. Hyles hybr. pauli *, Mory, " Mitt. Schw. Ent. Gesell.," x., p. 350, fig. 1 

 (1901). — Head dark olive-green above, white towards the sides; palpi grey, 

 terminal joint below dark grey, above olive-green ; antennae white above, 

 pectinations red-brown. Thorax dark olive-green above ; white towards the 

 sides, the inner edges of basal half of patagia white; reddish-grey beneath. 

 Abdomen above dark olive-green; the 1st and 2nd abdominal segments each 

 bear laterally a black spot with white scales behind each spot ; brown-grey 

 beneath, the centre grey with scattered black hair-scales, the 1st abdominal, 

 however, whitish, without black hair-scales. Wings pointed, but not so acutely 

 as those of T. hippophaes ; the disc whitish-grey, the margins grey, the costa 

 olive-green, blended with the three somewhat darker dorsal f spots; oblique 

 band darker olive -green, broad on inner margin, towards apex much waved, 

 the costal border indistinctly dentate ; at the base a black ^pot bordered at 

 sides with white scaling, reaching the inner margin at its base and touching 

 the first costal spot at its apex. Alost of the nervures are white where they 

 pass through' the oblique band. Fringes on outer margin dark brown, on 

 inner margin white. The upperside of the hindwings is of a salmon-pink ground- 

 colour, just as in T. hippophaes, the basal black spot extends towards the middle 

 of the wing and joins, at the outer angle, the very broad marginal band ; anal 

 angle white ; fringes white. The underside ol wings are very similar to those 

 of Hyles tithymali, both in colour and markings as well as the sprinkling of black 

 scales. The uppeiside (especially of the forewings) also bears a certain resem- 

 blance to H. tithymali. 



The moth from which this description was made was bred 

 from a pupa obtained from a larva taken in 1897, near Sion, in 

 the Valais, by Paul, on Hippophae rhamnoides. No description of 

 the larva was made, but, on the superficial appearance of the imago, 

 and without any further evidence, Mory concludes that the parentage 

 of the moth is $ euphorbiae X 2 hippophaes.

 is, in its penultimate instai, light green, with an ill-developed yellow spot on 

 each segment on either side of the darker dorsal stripe. The horn is light red, 

 black at the tip. The length of the largest larva almost 100mm. In the last 

 instai^ the ground-colour is light olive-green, flesh-colour, or reddish vent rally ; 

 on either side is a fine yellow-green dorsal stripe, and not far from this stand 

 ten — on the anterior segments quite small, on the posterior larger — yellow 

 spots on a black ground, and, for the most part, having a brick-red tinge in 

 the middle ; on each segment there is a blackish spot towards the venter ; on 

 the sides, as far as to the yellow spots, and also between the same, the larva 

 is covered with fine red -yellow dots, which sometimes appear only sparingly, 

 and are then usually lighter ; the head and caudal horn are red ; the former 

 about the mouth black, whilst behind it stands a red prothoracic shield ; the legs, 

 prolegs, and anal claspers black, spotted with red. The pupa, of which the 

 wino--cases are darker than the rest of the body, is coffee-brown with blackish 

 dashes and dots ; the spiracles black. None which I have seen have exceeded the
