AND THEIR TRANSFORMATIONS. 
8] 
Although there are only two European species, the number of North American ones is very considerable *. The 
oresent genus diffe , xt 1 oY 3 We ; ; 
] genus differs from the next in the form of its wings, which are subtrigonate, with the outer margin 
rounded, the porrected palpi turned upwards, and the more robust body and female antenne ; these organs in 
the male are simple.

Tortrix (and Chelonias) Testudinana, Hiibner. | 
This interesting insect varies from 3 to 14 inch in the expanse of the fore wings, which are of a dark orange 
or reddish colour, with two oblique slender dark streaks, one of which extends from the middle of the costa 
nearly to the base of the inner margin, and the other from beyond the middle of the costa towards the anal angle, 
the space inclosed between them being often darker, and varied with fulvous spots, especially in the males, whilst 
in the females the wings are but little varied in colour; the males, moreover, have the hind wings dusky. 
The caterpillar is onisciform, naked, and green, with two whitish dorsal stripes. It feeds on the oak in 
September, and the moth appears in June; but is comparatively rare, sometimes, however, occurring in small 
quantities in the Kentish woods. 

HETEROGENEA +, Kwnocu. 
Mr. Stephens separates this group from the preceding in consequence of the “ trigonate form of the fore wings, 
which are somewhat truncated posteriorly ; the thorax and abdomen are rather slender, and the antennz in the 
female are more slender than in that sex of Limacodes, and the palpi are very minute.” 
SPECIES 1.—HETEROGENEA ASELLUS, Puare XVI., Fie. 8, 9, and 30. 
Synonymes.— Hepialus asellus, Wien. Verz.; Fabricius; Stephens Tortrix Asellanana, Hiibner; ditto, Verz. bek., Sch. (Chelonias 
(Heterog. A.), Ill. Haust., 2, pl. 17, fig. 2; Wood, Ind. Ent. pl. 7, | Asell.). 
fig. 89. Heterogenea cruciata, Knoch, Beitrage. 
This species varies from 4 to 2 of an inch in the expanse of the fore wings, which are of a brownish clay 
colour, without any spots, the fringe dusky, the hind wings dirty brown, ‘The caterpillar is described by 
Fabricius as being of a red colour, with a dorsal yellow line spotted with black, and the sides green, and as 
feeding on the poplar. It appears in June, and has hitherto been found only in the New Forest, where it is 
very rare. 

FUMEA, Haworrn. PSYCHE, p. Scuranx. 
The insects composing this and the next genus are still more anomalous than the Apode, the males being 
winged, whilst the females are wingless ; they, however, possess legs and antenne, whereas the females in various 
species, which are still retained as congeneric by Boisduval, are vermiform. These, therefore, differ still more 
from the little Chimney-sweeps (as the species of the present genus are called by collectors) than Psyche fusca, 

*% Several of these are copied in plates 21 and 22 of Mr. Duncan’s volume of Foreign Moths, just published ; but the insect represented 
at figure 2 of plate 22 as the imago of fig. 1 (which is evidently a Limacodes) is one of oe Anthroceridee, and is closely allied to Syntomis. 1 
possess specimens of it captured in Brazil by Mr. Swainson. Bombyx vulnerans of Lewin seems to be the Australian type of the same group, 
which, without sufficient characters, Mr. Duncan has termed Doratifera. 
+ So named from the heterogencous character of the caterpillar.
