344 LÉPIDOPTÉROLOGIE COMPARÉE 



(i) Lycïa (Hiibner), type hirtaria (^chosen by Hulst, in 1896); 

 other species : Jirsaria (Walker). 



(2) Ithysia (Hiibner), type zonarïa (Hulst, 1896); other species : 



alpina (Sulzcr); ïtalica (Harrison), grœcaria 

 (Bdv.). 



(3) Pœcilopsis (Harrison), iy^^Q pomonaria (Harrison, 1910); other 



species : lapponaria (B.), rachelœ (Hulst). 



It is not necessary to repeat the characters of the gênera Ithysia 

 and Lycia hère, but, as there has been no previous diagnosis of 

 the new genus Pœcilopsis, the deficiency is remedied now. 



Pœcilopsis, gcn. nov., Harrison. 



Imagines not large. Maie fully winged. Head, thorax and 

 femora thickly covered with rough hairs mingled with strong red 

 scales and hairs ; not quite so rough as in Lycia, but much more 

 so than Ithysia. Abdomen more slender and hairy than in Lycia 

 or Ithysia, red speckled or lined. Thoracic crest f aintly indicated. 

 Antennas strongly pectinated although not quite to the apex. The 

 palpi short and the tongue slight. Termmal spurs of posterior 

 and middle tibias very weak or practically obsolète contrastmg 

 greatly with the development of thèse spurs seen in /. italica, 

 grœcaria, etc. 



Wmgs more or less hyaline and the lines nearly obsolète. 

 Vems very strongly marked. Neuration much as in the other 

 gênera except that veins 3 and 4 in both pairs of wings are 

 separate or rise from a point (PI. N, Fig. 2). Costal hollow well 

 marked and fully scaled with orange scales. 



The maie genitalia (See PI. E and F), like those of ail the 

 other gênera, are very simple. 



We hâve the strongly chitinised uncus with the end shaped like 

 a bird's head, with the tip of the bill rounded and clothed with 

 stout hairs. Then ventrally, we hâve the chinlike gnathos with a
