84 BRITISH MOTHS 



Species 3. — Deep ana uncula " ?. — It appears very doubtful how far the true B. uncula of Hiibner is a 

 British species, since the old specimen described by Mr. Haworth does not accord therewith ; and Mr. Curtis 

 jAu<, «UjK"er»-' States that he was not aware of any British specimen of the Hiibnerian insect existing in our cabinets. The 

 *a«i« ■^ao»«<.i^«' fv< following is Mr. Stephens' description of specimens given to him by Mr. Haworth, taken, as is stated, in the 

 metropolitan district : — " Expansion 15 lines ; wings tawny-yellowish ; anterior, with two paler approximating 

 streaks, between which are two small, nearly united dusky points of similar size ; at the apex of the hinder 

 margin is a dusky patch ; posterior wings paler in the male, with three pale luteous streaks. Female with all 

 the wings paler, and the markings very indistinct." 



•" Synokymes. — Bombyx uncula, Hiibner? 

 Drepana uncula, Stephens ; Wood, fig. 755. 



Species 4. — Drepana unguicdla" — (Plate LXXIV., Fig. 7) — Measures 14 or 15 lines in expanse; fore 

 wings not so much hooked as in the preceding, dark fulvous, with two paler streaks, being more widely apart 

 towards the costa ; the space between them darker brown, with a brown spot towards the costa ; the apical 

 margin dusky, with a pale striga ; hind wings similarly coloured to the fore ones. The caterpillar is dusky- 

 brown, with the back red. It feeds on oak, beech, and blackthorn ; and the moth appears in May and June, in 

 Richmond Park, Eppiug and New Forests, Dorsetshire, &c. 



° Sykonymes. — Bombyx unguieula, Hiibner ; Haworth ; Stephens ; Wood, fig. 756. Godart, 140, 4. 



Bombyx sioula, Esper. 



Species 5. — Drepana fasciata" — Measures 17 lines in expanse; wings brownish-lutescent ; the anterior 

 with two oblique brown strigse, incurved towards the costa ; the hind wings with a single striga. Thus 

 described by Haworth, from a specimen of unknown locality, in the collection of the late Mr. Swainson.

CILIX, Leach. EUCLEA, Hubner. 

 The pretty little insect which is the type of this genus differs from all the other species of this group, in 

 having the extremity of the fore wings not hooked, and the apical margin rounded ; the palpi are short and 

 slender ; the antennae of the males are slightly bipectinated, and those of the females subserrated ; the hind 

 tibicB have two pairs of spurs. The caterpillar is lacertine in its form. The moths, during repose, sit with their 

 wings carried vertically, instead of extending horizontally, as they are in the species of Drepana. Platypteryx 

 lacertinaria sits, however, with its wings deflexed, like the roof of a house. — Lyonnet Posth. Eech., pi. 35. 



., Species 1. — Cilix compressaP — (Plate LXXIV., Fig. 8) — Measures from 10 to 14 lines in expanse; 



*,i>. wings pearly- wh ite ; fore ones with a large central blotch of grayish-brown, extending to the hind margin, 



where it is darkest, and tinged with several leaden-coloured scales ; the veins of the wing in this patch being 

 silvery ; apical margin with two rows of gray lunules, preceded by a dusky shade ; hind wings with the 

 margin dusky. The caterpillar is reddish-brown, with the back gibbose, and the taU acuminated. It feeds on 

 blackthorn ; and the moth occurs throughout the summer, and is a very common species.
