4. dealbana, Frol. Alls anticis albis ; basi fascia rhombea fusca.

 analem macula ocellari plumbea; posticis fuscis. <$ Exp. al.

Head fuscous in front, sub-ochreous behind and above the eyes. 

 Face drab. Eyes black. Palpi fuscous, with the apices dirty white. 

 Antennae dark brown, alternated with a paler shade. Thorax in 

 front dark fuscous, paler on the vertex. Patagia fuscous at the 

 base, the apex sub-ochreous. Anterior wings dull, pale cream-colour 

 with black, brown, fuscous and greyish clouds and markings ; at the 

 base is a deep fuscous patch, streaked transversely with dark brown, 

 somewhat paler towards the costa, and sometimes also at its origin ; 

 its posterior margin is convex to the fold, then dilates towards the 

 dorsal margin, which it attains, after forming a strongly- denned 

 obtuse angle. The costal and dorsal margins maculated with fuscous 

 and brown ; the former distinctly so, in broad and narrow oblique 

 streaks on its apical portion ; an ochreous brown spot at the apex. 

 At the centre of the costa is an irregular fuscous cloud, extending 

 obliquely towards the anal angle and having a strong black or 

 intense brown streak across the middle, towards the apical margin. 

 Within the anal angle is an obtuse trigonate mark of ochreous or 

 pale fuscous, irrorated with black. In the apical region is a fuscous 

 cloud, and below it are two curved lustrous leaden-coloured streaks, 

 in a roundish white space, together forming an indistinct ocelloid 

 patch. Apical scales dark brown, somewhat interrupted, with pale 

 cream-coloured bases, cilia fuscous, mottled with black, and pale 

 bases, both becoming white at the anal angle. Posterior wings 

 clothed with coarse fuscous scales on a pale-grey ground. Marginal 

 scales fuscous with luteous bases. Cilia shining and paler. Abdomen 

 pale fuscous, the caudal tuft straw-colour. $ Exp. al. 6 lin. In 

 colour slightly darker than the $ . 



A very common species, subject to great variation in the 

 colouring, and slightly so as to size. On the one hand it is 

 very like H. neglectana, but the markings are neither so large nor 

 so distinctly expressed, and the colour is less black -, on the other, 

 it resembles H. Aceriana ; but this latter species is larger, the 

 cream-coloured ground richer, and the basal patch not so angulated. 

 Stephens mentions two varieties in the ' Museum Catalogue/ 

 viz. incarnana and Paykulliana, the former being slightly re- 

 moved from the type by a faint suffusion of the pale parts of 

 the wing (see Wood, Ind. Ent. pi. 32. fig. 966) ; the latter is 

 still more suffused and smaller in size (vide /. c. fig. 967). To 

 these should be added Alnetana, or the very suffused examples, 

 which Mr. Stephens has elevated to the rank of a species, with 

 a mark of doubt, we presume on the authority of Guenee, who
