290 THE entomologist's recoed. 



Moths," ii., p. 155 (1844); Desv., "Zool.," iii., p. 842 (1845); Staud., 

 "Cat.," 2nd ed., p. 232(1871). Cyistana, Hb., "Eur. Schmett.," fig. 176 

 {post 1800); Dup. "Hist. Nat.," ix., pi. 244, fig. 1 (1834).— Upper wings 

 yellow-brown with dark shades ; a broad irregular white mark and a tuft 

 or button on the centre of each. Head and thorax white clouded. Lower 

 wings pale brown. It is distinguished by the unusual form of the white markings on 

 the upper wings, and particularly by the tuft or button which is situated in an 

 upright position near the centre of each ; these tufts appear only slightly feathered 

 on the upper parts to the naked eye, but when one of them is examined with a 

 microscope, or even common magnifier, it presents the appearance of a bundle of 

 fibres enclosed within a thin membrane ; narrow at the base, increasing in bulk 

 near the middle, and expanding at the summit into a number of shoots, in the 

 form of a crest ; several other tufts are dispersed near the extremities of the upper 

 wings, but they are not conspicuous to the naked eye. Coombe Wood in Surrey, 

 Kent (Donovan). 



39. ab. suhcristalana. Curt., " Brit. Ent.," 2nd ed., expl. pi. xvi., no. 10 {ante 

 1839); H. and Westd., "Brit. Moths," ii., p. 155 (1844); Desv., "Zool.," iii., 

 p. 843 (1845). — Palpi, head and collar ash-colour, superior wings beautifully 

 variegated and similarly marked to cristalana, Don., but entirely brown, the 

 broken angulated fascia at the base and the button are very dark brown, the 

 curved semiloop on the costa is pale purplish-brown, and at the apex is a lead- 

 coloured spot (Curtis). 



40. ab. unicolorana, Desv., "Zool.," iii., p. 841 (1845). — This insect has 

 generally been understood as the i^'o f a naii not Fabricius, but not at all agreeing with 

 his description I have given it the present name. Its colour is uniform dark green, 

 with the exception of the palpi, head and thorax, which are more or less dirty 

 white ; the button is very small, varying from a dark to a white dot (Desvignes). 



41. a}}, suhwnic.olorana, n. ah. {FL vi., fig. 18). — Head, thorax and palpi brown. 

 Anterior wings uniform brown, with large dark brown button, x^osterior wings 

 lightish brown. This aberration may easily be distinguished from unicolorana 

 which has no button, or only the very faintest trace of one. 



42. ab. vigrana, n. ab. — (PI. vi., fig. 19). — Head, thorax and palpi blackish. 

 Anterior wings blackish, mottled over with darker colour. Large black button, 

 posterior wings ashy. 



43. ab. rufinigrana, n. ah. (PI. vi., fig. 20).— Head, thorax and palpi blackish. 

 Anterior wings blackish, with a broad chocolate coloured marking extending over 

 the wing from the base towards the apex, the button is black, and from it a fine 

 black line runs along the edge of the chocolate marking towards the apex, posterior 

 wings light brown. The chocolate coloured marking which is totally absent 

 in ab. nigrana constitutes the difference between these two aberrations. 



44. ab. atrana, n. ab. (PI. vi., fig. 21). — Head, thorax and palpi yellowish. 

 Anterior wings blackish, suffused with darker marking; large black button, and 

 broad bright orange coloured vitta, posterior wings greyish-brown. The orange 

 vitta makes it easy to distinguish this aberration from the two foregoing ones 

 which it otherwise greatly resembles. 



45. ab. merlana, n. ab. (PI. vi., fig. 22). — Head, thorax and palpi ashy. 

 Anterior wings uniform black with large button, and an ashy coloured vitta, 

 posterior wings light brown. This aberration is much like ab. nigrana or ab. 

 rufinigrana, and might at first glance be taken for them, the ashy vitta is its 

 distinguishing feature. 



46. ah. sequana, Curt., "Brit. Ent.," 2nd ed., pi. xvi. expl., no. 13 {ante 

 1839) ; Desv., " Zool.," iii., p. 843 (1845).— Similar to ab. fulvovittana, but 

 smaller and having no white in the superior wings, which are purplish-brown and 

 variegated, an angulated brown space at the base spotted with black, button large 

 and ochreous at the apex, with a short black streak beyond it, the semiloop on the 

 costa purplish-grey, apex lead-colour, inner margin ochreous ; palpi, head and 

 centre of thorax pale ash-colour (Curtis). 



47. ab. lichenana, Curt., "Brit. Ent.," 2nd ed., pi. xvi. expl., no. 7 {ante 

 1839). — Superior wings purplish-brown with a large black button and a few small 

 tufts at the anal angle ; a bright ferruginous line from the button towards the apex, 

 softened into the costa ; head, thorax and a large patch at the base of the inner 

 margin white (Curtis). 



48. ab. scviiu.stana, Curt., "Brit. Ent.," 2nd ed., pi. xvi. expl., no. 2 {ante 

 1839) ; H. and Westd., "Brit. Moths," ii., p. 153, pi. xcii., fig. 2 (1844); Desv., 

 " Zool.," iii., p. 843 (1845). — Superior wings dull ochreous, button brown-black,
