JSTo. 6538. 

 Wings pale cinerascent, slightly glossy, the anterior thickly covered with 

 numerous darker strigte and fasciae, composed, as it were, of fuscous clouds 

 and black spots, the band m the middle of the wings being most conspi- 

 cuous, and having a black dot within it towards the costa ; on the hinder 

 margin is a row of geminated black dots : posterior wings whitish, with two 

 darker evanescent striga on the middle, the hinder margin with a row of 

 geminated black dots : ciha cinereous. 

 Slightly variable in tint, some examples being of a darker hue than others, and 

 more distinctly fasciated. 1 possess one specimen of a very dark fuscous-ash, 

 spotted with white; and another of a pale ashy-white, with a very distinct 

 unsolid central fascia, as in the other species of this genus. 

 Although this insect diflPers a little from the other species of this genus, the 

 close approximation of its female to that of Cidaria didymata, and of some 

 of its varieties to those of La. bipunctaria, seem to indicate that this is 

 its true location J— it certainly cannot associate with Oporabia dilutata, with 

 which it has lately been united ! inasmuch as the antennae of the male are 

 pectinated, whereas in Oporabia they are but slightly ciliated. 



Rare : found on heaths near London in March : I have several 

 times taken it on Hampstead-heath. " Epping."— i¥r. Doiibleday. 



Genus CXCIX. — Cidaria, Treitschhe. 



Palpi short, densely squamous, the terminal joint concealed, obtuse; triarticu- 

 late, the two basal joints of equal length, the first curved, the second straight, a 

 little attenuated, terminal minute, subglobose : maxilla; rather long. Antenna; 

 rather short, each joint producing, in the males, a pubescent branch on each 

 side, excepting towards the apex, which is simple, and at the base ; in the 

 females simple, and shghtly pubescent within: head small: et/es globose: 

 ^/loraa- slender: Wmg-* forming a triangle during repose, subtrigonate, entire, 

 the anterior with the hinder margin slightly acute, traversed with a broad 

 central fascia composed of waved lines, and sometimes abbreviated, and 

 towards the hinder margin, near the apex, are usually two conspicuous, nearly 

 united spots : abdomen slender, obtuse in the males, conic and stouter in the 

 females. Larva with 10 legs, slender, smooth, naked, and generally spotted; 

 head rounded : pupa in a folli cuius among leaves. 



The species of Cidaria may be known from the foregoing 

 insects by their comparatively shorter wings, which have their 

 hinder margin more rounded and entire, the anterior not very 

 acute at the apex, and adorned with a central fascia, in which are
