the outer side. The larvae have spots on the 

 back and hve on oak. 



D. convergens, W. V. Fore wings violet- 

 grey, with a brown central area and a hook- 

 shaped black streak from the middle of the 

 base, and a whitish spot in front of this 

 reaching to the costa. It has a marginal line 

 and both the lighter transverse lines, of 

 which the anterior is hardly indented, and the 

 three stigmata, of which the claviform is large 

 and darker than the rest. The reniform stigma 

 is yellowish in the middle. Between the orbi- 

 cular stigma and the central shade, which 

 touches the claviform stigma, is a pale tri- 

 angle. In cell lb, near the hinder angle, there 

 is a rusty yellow blotch. The hind wings 

 are bluish grey, with a black marginal line, 

 and a lighter curved line and fringes. The 

 head and thorax are violet-grey, and the collar 

 and teguIzE are edged with black towards the 

 wings. It is found in Central Europe in 

 August and September. The larva is pale 

 yellow, dotted with white, with an interrupted 

 dorsal line edged with reddish brown, a yel- 

 lowish one beside it, and another above the 

 legs. There is a transverse row of dark red- 

 dish brown dots on the third and fourth seg- 

 ments, and from the fifth segment onwards 

 an irregular brown spot, indistinct in the 

 middle. The head is light brown. It feeds on 

 oak in May and June. The pupa is reddish 

 brown, with a terminal point. 



D. aeruginea, Hiibn. Fore wings brownish 

 grey, with a slight violet lustre and golden 

 yellow markings. The stigmata and base are 

 varied with green. The large claviform stigma 

 is sharply bounded by black, and its tip 

 touches a sharp angle of the posterior trans- 

 verse line. In front of this line is a golden- 

 yellow blotch reaching to the golden-yellow 

 submarginal line. In front of the angle and of 

 the tip of the stigma is a pale spot. The 

 nervures are darker in the marginal area. 

 The hind wings are white, with dark nervures. 

 The marginal line and central lunules are 

 greyer in the female. The head and thorax 

 are brownish grey, the collar with a double 

 black margin, having a golden-yellow stripe in 

 front of it. The abdomen is pale ashy grey. 

 The moth is found in September in woods in 

 South-Central and Southern Europe. The 



larva is whitish \ellow, varied with reddish 

 yellow dashes in front, and transversely dotted 

 with rusty brown. There is a white dorsal line 

 which bisects a series of lozenge-shaped red- 

 dish yellow spots on the fifth and following 

 segments. The spiracles are black, with white 

 rings and a few dots near them. The head 

 is brownish yellow. It feeds on oak in May. 

 D. aprilina, Linn. The Marvel du Jour. 

 PI. XXV. fig. 6. is common in Central Europe 

 in September and October, especially in oak 

 woods. The larva is dirty white, marked with 

 yellow and black, and with a white longitudinal 

 stripe above the legs. It lives in May and 

 June on oak, hiding between the ridges of the 

 bark during the daytime. 



Genus Chariptera, Guen. 



Wings shorter, wiJi broader hind margins 

 than in D. aprilina. Front and palpi with 

 depressed scales. The hair on the thorax 

 smooth, mixed with smooth scales. Fore wings 

 olive-brown, with pale green markings. The 

 larvae are stout in front, with four spines be- 

 hind. The only species is: 



C. culta, W. V. PI. XXV. fig. 7. This 

 pretty moth is found in South-Central Europe 

 in June, but is a somewhat scarce insect. 

 The caterpillar is green or brown, with bluish 

 lozenge-shaped spots on the back and dark 

 spots on the sides. It feeds at night on sloe, 

 pear, etc., in August and September, and 

 hides under moss or lichens during the day. 



Genus Miselia, Steph. 



These moths are closely allied to the last 

 Genus. The fore wings are broader towards 

 the ends. The thorax is coarsely hairy flat- 

 tened, with an elevated border on the sides, 

 and an angular projection in front. In the male 

 of oxyacantha the antennae are short and stout, 

 with thickly ciliated serrations. The larvae 

 resemble those of Chariptera. 



M. bimaculosa, Linn. Fore wings ashy 

 grey and brown, with dentated hind margins. 

 The two transverse lines are deeply zigzag, 

 edged with darker on the sides, and there are 

 three large stigmata. The orbicular stigma 

 is broad, and the reniform white, the two 

 being connected by a black streak. The sub- 

 marginal line is indistinct, but forms a black
