 Taken by Zeller in Sicily ; the larvae abundant on Thapsia 

 garganica ; sometimes 50 — 60 larvae on one plant. He bred the 

 perfect insect from April 30th to June 4th ; but never saw it at 

 large.

 Yeatsii, Haw. 

 Putridella, Hiib, 244? Haw. 



Distinguished from all its congeners by the glossy pale greyish- 

 purple anterior wings; it is more or less dusted with fuscous; 

 and frequently the nervures of the hinder portion of the wing 

 are darker ; it then becomes the putridella of Haworth ; but Hiib- 

 ner's figure of putridella, if meant for this species, is very bad. 



Taken rather commonly by some of the collectors at the east 

 end of London. 



Sp. 24. Intermediella, n. sp. (PI. XVH. fig. 4.) 



Alae anteriores ad apicem ohtusie, nee rotundatcs ; ochraceae, 

 plus ininusve rufescentes, atomis fuscis conspersis, punctis 

 duobus oblique positis ante medium, duobus albis pone me- 

 dium, et supra ea macula fusca. 



This forms a connecting link between the group of which are- 

 nella may be considered the type and applana ; the form of the 

 anterior wings is nearly square at the apex, thus very different 

 from applana; the ground colour of the anterior wings is ochreous, 

 or reddish ochreous, interspersed with numerous fuscous atoms ; — 

 before the middle are two black spots placed obliquely and be- 

 yond them two smaller white ones margined with black, and above 

 these is a fuscous blotch ; towards the base is the ordinary dark 

 shoulder mark, which reaches about half across the wing. 



Expansion of the wings, 9 — d\ lines. 



Head ochreous. Face paler. Palpi, second joint, pale ochre- 

 ous above, beneath rather darker, terminal joint pale ochreous, 

 but with the base, a ring before the apex, and the extreme 

 apex, fuscous. Antennae fuscous. Thorax ochreous or reddish 

 ochreous, according with the colour of the anterior wings. Ab- 

 domen pale ochreous. Legs pale ochreous, the anterior rather 

 darker on the outer side. Tarsi ochreous, rather darker than the 

 legs. Anterior wings described above ; a little before the hinder 

 margin is an indistinct angulated fascia, which, from not being
