70 VARIETIES OF NOCTU^J 



series of large black spots exteriorly edged with white lunules " 

 (' Histoire naturelle ' etc. (Deltoi'des), vol. viii., p. 34). The description 

 I made of Hiibner's figure is as follows : " Anterior wings dark 

 chocolate-brown, almost blackish-brown, with a black basal longitudinal 

 streak and a transverse black basal costal streak (part of the basal 

 line) ; reniform black ; a black patch in the centre of the wing below 

 the reniform ; the elbowed line paler, brownish at the costa, the 

 lower part lost in the ground colour ; the subterminal made of white 

 lunules. The hind wings dark grey with a blackish lunule " (' Samm- 

 lung europ. Schmet.' etc. (Pyrales), fig. 163). This is a most extreme 

 form, of which I have seen no representative. 



Hypenodes, Gn. 



This genus contains only two species albistrigatis and cosfce- 

 strigalis both of which are British. Stephens included these in his 

 Cledeobia, but as he had previously used the latter name in a much 

 more extended form in his ' Catalogue,' the present genus was formed 

 by Guenee and the name Cledeobia retained for the principal genus of 

 the family Cledeobidce. Guenee writes of this genus : " The Hi/pen- 

 odes are very delicate little species which fly in the damp and shady 

 parts of woods and which are very rarely met with fresh, the markings 

 of the second species (costcestrigalis) especially, being almost always 

 partly effaced. As to its characters, they are very distinct from the 

 other Hypenidce on account of the absence of the stemmates and by 

 the neuration " (' Histoire naturelle ' etc. (Deltoi'des), vol. viii., p. 41). 



Our two British species are of much the same size and general 

 appearance, but costcestrigalis is to be distinguished by the dark costal 

 blotch before the elbowed line, whilst albistrigatis has no dark costal 

 blotch before the elbowed line, the latter being very conspicuously 

 edged with white. 



Hypenodes, Gn., costcestrigalis, St. 



This species appears to be much commoner than its congener in 

 Britain and also on the Continent of Europe. It frequents marshy places 

 and damp woods, in which localities I have occasionally captured it. 

 The type was described by Stephens as follows : " Alis fusco-cinereis 

 anticis macula subtriangulari versus apicem costse fusca, lineolaque 

 obliqua apicis alba, posticis albidis. (Exp. alar. 10 lin.)." " Wings 

 ashy-brown ; the anterior, with a somewhat triangular fuscous patch 

 towards the apex of the costa, bounded by an oblique white streak, 

 which terminates in a pale whitish-ash blotch ; the hinder margin is 

 brownish, with a faint waved whitish streak ; and on the external 

 edge is a row of detached black lunular dots ; posterior wings whitish, 

 with the apex fuscescent : cilia of all the wings, fuscous. A rare insect ; 

 the only locality I am aware of being in the vicinity of Whittlesea Mere, 

 and near Swaffham in Norfolk, where it was taken by the late Mr. 

 Haworth" (' Illustrations ' etc., vol. iv., p. 21). Guenee describes this 

 species and then writes : " Herrich-Schaffer has confounded this 

 species with albistrigalis, in fact his figure represents neither species 

 very exactly. Altogether the elbow of the median line and the pale 

 colour of the inferior wings make me think he had this species before 

 him " (' Histoire naturelle' etc. (Deltoi'des), vol. viii., p. 43).
