obscure line towards base, irregularly angulated above middle ; a second

 marked with dark fuscous or blackish blotches ; a sinuate cloudy dark 

 grey median shade, often obsolete ; a similar shade from apex, parallel and 

 near to second line. Hindwings moderate, hindmargin shortly dentate; 

 whitish-grey ; a cloudy fascia before middle, and a broad hindmarginal

82. Decl. crassitibia, Feld. 

 (Amphitape crassitibia, Feld., eix., 10 (?').) 

 Male. — 33-36 mm. Thorax with a strong crest curved forwards. 

 Abdomen longer and stouter than in P. floccosa, sometimes largely de- 

 veloped, with large anal tuft. Forewings as in D. floccosa, but costa 

 somewhat more sinuate ; whitish or pale ochreous, often partially suf- 

 fused with brownish, especially towards apex; costa with numerous fine 

 oblique black strigulae ; a short blackish longitudinal mark from base ; an 

 irregularly curved double dark fuscous or blackish line towards base, and a 

 similar twice inwards sinuate line at § ; both these vary very much in 

 shape, tending to be sharply angulated towards each other and even con- 

 nected on submedian fold ; second margined on upper half posteriorly by a 

 fuscous suffusion, more blackish on costa, followed by a pale apical space ; 

 generally two rows of blackish marks towards hindmargin. Hindwings as 

 in D. floccosa ; white or pale whitish-ochreous, hindmargin slightly suffused 

 with fuscous. 



Female. — Forewings with apex more projecting ; grey-whitish, very 

 finely irrorated with dark grey ; costal strigulaa as in male ; other markings 

 obsolete, or represented by a few blackish dots. Hindwings fuscous-grey, 

 paler towards base. 



Very variable, and the sexes are also very different ; but the species 

 may always be recognized by the fineness and obliquity of the costal 

 striguhe.
