Porthetria dispar and Orgyia gonostigma are from specimens in the British Museum; all the others are from specimens liberally furnished 
for the purpose by Mr, H. Doubleday. The larva of D. pudibunda is drawn from one taken last season by Mr. Parrel! of the Museum; that 
of O. antiqua is also drawn from nature; that of D. coryli is from Wilkes, and the others are from Hiibner. I have not figured the female of 
D, fascelina, as it scarcely differs from the male, except in size ; it is in general nearly > larger, H.N.H. 
We are now arrived at the more typical species of the present sub-family, Arctiides, distincuished by the 
more densely squamose wings, the broadly pectinated antennee of the males, and the very hairy caterpillars, 
which are sometimes, moreover, ornamented with thick tufts of hairs on the back. The chrysalides are often 
clothed with delicate hairs. They constitute Ochsenheimer’s three genera Liparis, Orgyia, and Eyprepia; and the 
tribes Chelonides and Liparides of Boisduval, which Mr, Stephens has, perhaps too extensively, separated into the 
followin g 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 Arctie and allies; 
Lelia, Stilpnotia, Leucoma, Phragmatobia, and Cycnia, have the wings more or less diaphanous; whilst 
Hypercompa, in its elongated tongue, approximates to the Lithosiide, 

PORTHETRIA, Hisner. HYPOGYMNA, Svepnens, nec. Husner, Verz. 
This genus has the spiral tongue obsolete, the wings fully developed in both sexes, and opaque ; the anterior 
tarsi simple and ‘slender; the body of the female is 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 and tail.

This species varies from 13 to 3 inches in expanse ; the male being of a dusky brown colour, and the female 
white ; being similarly marked in both sexes with several slender waved fasciw, the markings of which towards 
the costa are more decided. Varieties occur not only in the ground colour of the wings, the males having the 
wings sometimes pale brown, and the females dusky, but also in the depth of the colour of the 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 with 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.

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

and in the porrected, clavate palpi and antennez of the males, with the wings ornamented with dark waved
