thickened at the usual position of the cornuti. The 8th abdo- 

 minal tergite is not thickened. 



Ithysia italica, var. florenfina (Stef. nec graecaria, Bdv.). 

 PI. CLXII, Fig. 1585. 



In this form the ground colour is strongly suffused with light 

 brown whilst the markings and suffusions are much stronger than 

 in the type, and the thorax is quite brown. 



Ithysia italica, var. cariiiolica, var. nova, mihi. 



In this form the ground colour is grey heavily suffused with 

 blackish scales whilst the markings and suffusions are colder in 

 tone and much stronger than in the type. The thorax is dark 

 grey. 



Ithysia graecaria (Bdv.-Staudinger). PI. CLXII, Fig. 1586. 

 Wing expanse : 35-36 mm. 



This species was erected dehnitely by Staudinger in 1870, for 

 Boisduval's name, although proposed-in 1840, was without des- 

 cription. 



The ground colour of the wings is a dead grey, slightly mixed 

 with yellowish or brownish scales in the type. In the deadness 

 of the colour, we hâve a contrast to the gloss of italica and alpina. 

 The brown tmge is much more évident in the hindwings. On the 

 forewings the first, médian and second lines are ail présent, as 

 well as the subterminal band. The médian line is very near the 

 second one, which, at the Çth vein, takes a rapid inward sweep to 

 strike the costa nearly at right-angles. The subterminal white 

 band has both of the usual suffusions and is broader and less 

 prone to be scalloped than in the other two species. The markings 

 on the hindwings hâve the same characteristics. Both the suffu-
