AND TF^KTR TRANSFORMATIONS. gj 



IB 



Although tliere are only two European species, the number of North American ones is very considerable *. Tl 

 present genus differs from the next in the form of its wings, xvliich are subtrigonate, with the outer margin 

 rounded, the porrected palpi turned upwards, and the more robust body and female antenna? ; these organs in 

 the male are simple.

Tortrix (and Chelonias) Testudinana, Iliibncr. 



This interesting insect varies from | to 1> inch in the expanse of the fore wings, whicii 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 otiier from beyond the middle of the costa towards the anal an^le, 

 the space inclosed between them being often darker, and varied witli fulvuiis spots, especially in the males, whilst 

 in the females the wings arc but little varied in colour; the males, moreover, have the hind winfTs 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 Juno ; but is comparatively rare, sometimes, however, occurrino in small 

 quantities in the Kentish woods. 



IlETEROGENEAt, Knocm. 



Mr. Stephens separates this group from the preceding in consequence of the " trigonate form of the fore win»s, 

 which are somewhat truncated posteriorly ; the thorax and abdomen are rather slender, and the antenna? in the 

 female are more slender than in that sex of Limacodes, and the palpi are very minute." 



SPECIES 1.— IIKTEROGENEA ASELLUS. Plate XVI., Fig. 8, 9, and .3U.

Tortru' Asellanarui, Illibner; ditto, Veiz. bek. Sch. (Clieloniaa 

 Asell.). 



lleterogenea cruciata, Knoch, Bcitrnge. 



This species varies from ^ to ;[ 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 caterjiillar 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, Haworth. PSYCHE, p. Schrank. 



The insects composing this and the next genus are still more anomalous than the Apodw, the males being 

 winged, whilst the females are wingless ; they, however, possess legs and antennfe, whereas the females in various 

 species, which are still retained as congeneric by Boisduval, are vermiform. These, therefore, diiFer 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 tlie Anthrocerida;, and is closely allied to Syntomis. I 

 possess specimens of it captured in Brazil by Mr. Swainson. Bomby.t vulucrans of Lenin seems to be the Australian type of the same group, 

 which, without sufficient characters, Mr. Duncan has termed Doratifera. 



t So named from the heterogeneous character of the caterpillar.
