HyBOCAMPA UrOPUS — StA UROPVS. 1-1)1 



and alder. {C. Verbasci, Fabr., from South France, is pure white, with bluish-black spots on 

 the fore-wings, which are mostly arranged in two interrupted bands ; and three orange dots. 

 Expands i^ inches. C. Interntpta, Christoph, from Sarepta, is rather larger than Bifida ; the 

 fore-wings are chalky-white, spotted with black at the base and hind margin, with a black 

 central band, broadly interrupted in the male, and sinuated on both sides in the female ; 

 but with no reddish-yellow markings ; hind-wings white. C. ^^niginosa, Christoph, also from 

 Sarepta, is allied to Diatspis ; the head, thorax, and fore-wings are pale ochreous. The latter are 

 spotted with black at the base and hind margin, and marked with a transverse ashy-grey band, 

 waved on the inside, and denticulated, but scarcely waved, on the outside, and bordered with black. 

 Hind-wings whitish, with ochreous fringes. Size oi Bicuspis. It appears in June.) 



GENUS V. — HYBOCAMPA (LED.). 



The thorax is densely clothed with flattened hairs ; the fore-wings are rather narrow, and 

 pointed at the tips ; the hind margins are rounded, and the fringes very short. The larvae 

 have fourteen legs, and are truncated behind. There are humps on the six middle segments. 

 They become pups in a firm cocoon, covered with pieces of bark and moss, and attached 

 to the trunk of a tree. The only species, H. Milhaicseri (Fabr.), has the fore-wings varied 

 with lighter and darker grey, a broad interrupted blackish stripe on the inner margin, and 

 an oblique pale yellow band beyond the middle, which is not sharply bounded. The hind- 

 wings are white, spotted with black at the anal angle. Expands li inches. Widely distributed 

 in Southern and Central Europe, except Britain, but always scarce. It appears in May and 

 June. The larva is green, granulated with whitish, with a broad pale brown stripe on the 

 sides ; there are small red points on the humps of segments 6 to lO, and a branch-like 

 excrescence, divided above, on that of the 5th segment. It lives on oak in July and August, 

 and the cocoons, which are very difficult to distinguish from the bark, are nearly always found 

 hollowed out by woodpeckers. The moth and larva are figured at PI. 30, Fig. 7, a, b. 



GENUS VI. — UROPUS (BOISD.). 



The thorax is clothed with woolly hair; the fore-wings are rather long and pointed, with 

 the hind margin slightly sinuated, and the hind-wings are short and narrow. The tongue is 

 long and horny, and the antenns are more than half as long as the tore-wings. The larvae 

 have fourteen legs, and rather long bodies, clothed with fine and short hair, and the abdomen 

 terminates in two short diverging points. They change to pupae in the ground. The only 

 European species is U. Ulini (VV. V.), a moth with dark grey fore-wings, crossed by two black 

 transverse stripes, the hindmost of which is sharply dentated ; and white hind-wings. Expands 

 about 1 1 inches. It occurs in South Europe in April and May. The larva is brownish or 

 yellowish green, with a yellow stripe on the back divided with black, an indistinct pale line 

 on each side below it, and a black arrow-shaped protuberance on the 5th segment. It feeds 

 on elm in June. 



GENUS VII. — STAUROPUS (BOISD.). 



The thorax is woolly, the fore-wings are rather broad and slightly sinuated on the hind margins, 

 and the hind-wings are rounded. The fringes are longer than in Uroptis, the tongue is weak, 

 and the abdomen is slightly tufted above. The larva; have fourteen legs. They are naked,
