64 BRITISH MOTHS 



CLOSTERA*, HoFFMANSEGG. PYG.^RA (pars typica), Ochsenheimer. 



This "-enus agrees with Ilammatophora in the general form of tlie wings (destitute of teeth on the hind 

 margin) ; but tliey are shorter, and the outer margin is not denticulated: tliey are also niarlied with pale transverse 

 streaks, and a large chocolate-coloured apical patch ; the antenna? are also short and bipectiuated in both sexes ; the 

 thorax is only crested behind. The fore feet are not stretched forwards in repose ; the abdomen of the males is 

 lon<T, terminated by a bifid tuft. The caterpillars are thick, and slightly hairy, with the fourth and terminal 

 segment generally tubcrcled. They reside in a web, wherewith they draw together several leaves ; in which, 

 also, the pupa state is passed.

This species varies from 1 to 1^ inch in the expanse of the fore wings, which are of an ashen colour, with four 

 pale, transverse, slender bars, which unite together ; a brovvnish spot on the costa close to the fourth stripe ; 

 beyond which is a large chocolate-coloured patch, which does not extend to the tip. The hind wings are dirty 

 bi'own. The thorax black in front, with the sides ashy. 



The caterpillar is brown, with a broad, pale, dorsal stripe, and a row of yellowish rings at the sides of the 

 body. This is a rare species, but occurs in several of the woods in the London district. It has also been found 

 near Cambridge, Dublin, and in the Isle of Arran. 



The caterpillar feeds on the aspen, willow, and poplar, beneath the bark of which it is sometimes found, in 

 tiio autumn ; the moth appearing in May and July, or August. 



Clostera Anasto.mosis, Linn. (Wood, Ind. Ent. t. 53, fig. 30, and our fig. 5 and 5), was recorded by 

 Stewart as a native species : but no British specimen is known in any cabinet. It measures 1|- inch in 

 expanse, and has the wings grey and varied with brown and dark red, with three whitish subanastomosing bars, 

 and a reddish thorax. The caterpillar bears considerable resemblance to that of CI. Anachoreta. 



SPECIES 2.— CLOSTERA SUFFUSA. Plate XIII., Fig. 8. 



SvNoNvMES. — Clostera reclusn, var. 0, Stepliens, lllustr. Haust. | C/. suffusa, Stepb. Illustr. H. 4, p. 38.t ; Wood, Ind. Ent. pi. 52, 

 pi. 16, fig. 1. If. 165(1. 



This species, which Mr. Stephens at first considered to be a variety of CI. reclusa, is rather larger than that 



insect, having the hind wings " pale-glaucous ash, with two aqgulated, fuscous, transverse strio-ce ; the fore wincrs 



with the third striga united obliquely with the fourth on the interior margin." It was described from a specimen 



in the collection of the late N. A. Vigors, Esq. and is now in the possession of the Zoological Society of London. 



No locality is given of this specimen, unless it be the individual recorded to have been captured at Dublin by the 



Kev. 3. Bulwer. 



* Dciivi'il fiom tlie (I'reck K\uiaT))p, fusns, evidently from tlic fusiform abdomen. Hnlnier's svnonymous name Icbtbvura (fish-taikd) has 

 a similar ulhision, as well as Ochsenhcimir's l*}gu-ra, as stated above.
