The whole of the insects in this plate are lignred from specimens sent nic by Mr. II. Doubledaj-, witli tlie exception of H. remissa, from a 

 specimen in the British Museum. Tlic cateriiilhus are from Hubuer. 



I have omitted H. satura, which is now considered merely a pale and slightly marked variety of H. adusta and also H. oblonga, which 

 Mr. Stephens now considers a variety of II. remissa, in his specimen of whicli, the stigmata and other markings arc rather largei,, iialcr 

 .-ind of more even colour than in the true species. If, on examining a specimen of H. obscura it is found to be distinct, a liuure of it will bl 

 given in a supplemental jdate. IT. N. H. 



IIADENA, SciiR.\NK, Stkpii. (IIADENA, pars. Bdv., Guen.) 

 Many of the moths inchided in this genus by our English authors are known to collectors under the name of 

 brocade motlis, from the rich shining patches of varied tints upon the fore wings, which have the two ordin.ary 

 stigmata distinct and rather appro.ximating towards each other, the basal one being placed obliquely ; the place 

 of the supplemental stigma is indicated by a dark oval jiatch edged with black, and there is a pale strio-a runnino- 

 near the apical margin of the fore wings wjiich is strongly angulated towards their posterior angle. The palpi 

 are bent upwards, but do not e.\tend much in front of the head, and they have the terminal joint sh'o-htly exposed; 

 the antennae are either simple or slightly serrated and ciliated beneath in the males. It is chiefly on account of 

 the diiferencc in the structure of the male antennte that ]\Ir. Curtis has separated the genus into two croups ; 

 confining the name of lladena, to the species figured in our thirty-fourth plate, and calling those represented on 

 the thirty-third by the generic name of Rhizolitha, a group cquivalei:t with Boisduval's tenth section of Hadena, 

 that genus being regarded by Boisdnval and Guonc'e as of far greater extent, and comprising the genera Charieas, 

 Mamestra, lladena. Trachea, and Eui>lexia, divided however into a great number of sections.

This species measures l-i inch in the expanse of tlie fore wings, which arc of a pale greyish-brown colour, 

 marked with brownish-black patches, having a black jiatch at the base within and a dark black line in the place 

 of the supplemental stigma, and with the stigmata and strigaj paler coloured, edged with blackish-brown, one of 

 the striga; being before and the other beyond the middle, both much waved and connected together by the black 

 line before-mentioned ; and beyond the stigmata is another pale striga deeply bidentate towards the posterior 

 angle, and edged within with black spear-shaped dashes placed between the veins ; the Iiind wings are whitish, 

 with the veins and margin dark. The thorax is grey-brown, with two slender black arches in front. This rare 

 species occurs in the woods of Kent and Surrey, also found on Cliatmoss by Mr. Edleston and by Mr. Doubleday 

 at Epping in May. 



Dark varieties of this species occur in many cabinets under the name of 11. Satura. Mr. Stephens also 

 considered it possible that his specimens described under that name might be varieties of II. adusta, as
