Portlictm Hispar and Orjiyia pinosticma arc from specimens in tlic Biitisli Museum ; all tlic otlici's are from specimens liberally furnished 

 for the purpose by Mr. 11. Doubloday. The larva of D. puililninila is drawn friim one taken last season by Mr. Parrel! of the Museum; that 

 of O. antiqiia is also drann from nature; that of 1). coryli is from Wilkes, and the others arc from Hiibner. I have not figured the fenjaU- nf 

 D. fiscelina, as it sc.ireely differs from the male, except in size ; it is in general nearly \ larger. H. N. H. 



Wo aro now arrived at tlic uunv typical sjit'cics of the present sub-family, Arctiide.s, distinn-uislitJ by tlio 

 more densely sqiiainosc wings, the broadly pectinated antenniB of the males, and the very hairy caterpilhirs, 

 which arc sometimes, moreover, ornamented with thieh tufts of hairs on the back. The chrysalides are often 

 clothed with delicate hairs. They constitute Oclisenheimer's three genera Liparis, Orgyia, and Eyprepia ; and the 

 tribes Chelonides and Li]iarides of Boisdiival, whieli Jlr. .Stephens has, perhajis too extensively, separated into the 

 following genera — of which the first four have the spiral tongue obsolete : — Demas, in its developed tongue and 

 opaque wings, and its tufted larva, forming a connecting link between them and the typical Arctia3 and allies ; 

 Lffilia, Stilpnotia, Leucoin.a, Phragniatobia, and Cycnia, have the wings more or less diaphanous ; whilst 

 Hypercompa, in its elongated tongue, appro.xiiiiates to the Lithosildte. 



PORTllETUIA, I!i:i!Ni=rt. HYl'OGViMNA, Stephens, nec. Uub.n'er, Verz. 



This genus has the spiral tongue obsolete, the wings fully developed in both se.xes, and ojiaque ; the anterior 

 tarsi simple and slender ; the body of the female i.s robust and obtuse at the tip, which is thickly clothed with 

 wool. The caterpillars are cylindric, hairy, and furnished with tubercles, emitting long pencils of hairs especially 

 on the sides of the head ami tail.

This species varies from 1 .' to li inches in expanse ; the male being of a dusky brown colour, and the female 

 white; being similarl\' marked in both se.xes with several slender waved fasci;n, the markings of which towards 

 the costa are more decided. Varieties occur not only in the ground colour of the wings, the m.ales having the 

 wings sometimes pale brown, and the females ihisky, but also in the deptli of the cidour of tiie markings, which 

 are also sometimes almost obliterated. The caterpillar is dusky, irrorated with black spots, with a pale dorsal line, 

 and the sides above the feet whitish ; the fore part also spotted witli blue, and the hind part with red. They 

 feed on the oak, lime, elm, and other trees, from June to August. It occurs in great profusion in the Hunting- 

 donshire fens, and has also been found in the neighbourhood of London. 



PSILURA*, Stephens. LIMANTRIA, Hi}BNER. 



This genus is far too nearly allied to the preceding, with which it agrees in the tubercled setigerous larvK, 

 id in the porrectcd, clavate palpi and antcnnsB of the males, with the wings ornamented with dark waved 



• Derived from i(.iAds, nudus, and ujpi, c:'nda,iu allusion to the pointed n.iked tail of the leuialcs.
