36 LEPIDOPTERA. 



Cleodora striatella, W. V. {Frontispiece, Fig. 6.) 

 Alis anticis griseis, lineis duabus albis, una plicae, altera 

 disci (punctis pono medium nigris), strigulis costa? apicis 

 tribus albis. Exp. al. 5 — 6 lin. 



Head and face greyish white; palpi whitish, tip of ter- 

 minal joint dark fuscous ; antenna? dark fuscous. Anterior 

 wings grey, a slender white streak runs from the base along 

 the fold ; in it in the middle is an elongate black spot; above 

 it is a less distinct white streak, with an elongate black spot 

 a little beyond the middle, and half-way between that and 

 the hinder margin is a round black spot ; towards the apex 

 an oblique white streak runs from the costa to above the 

 anal angle, and immediately before the apex are two short 

 white streaks from the costa sloping inwards; on the inner 

 margin, near the anal angle, are two or three short white 

 streaks ; a black line runs along the hinder margin ; cilia 

 grey, with two dark fuscous lines. Posterior wings grey, 

 with greyish fuscous cilia. 



From the different ground-colour and basal streaks this is 

 at once distinguished from our only other British species of 

 the genus, Cytisella. It, however, very nearly resembles an 

 Italian species Kefersteinella, but in that the broader an- 

 terior wings are more brownish, and the basal white streaks 

 are absent. 



I have a specimen of this species ; it came to my light on 

 the evening; of the 11th of August last. I am not now in the 

 habit of lighting my attracting lamp, but on that evening so 

 many moths came tapping at the windows of the room in 

 which I was sitting, that I resolved upon " lighting up," and 

 about half an hour afterwards the Striatella made its ap- 

 pearance. 



On the continent the insect is common, and the larva feeds 

 in the stem of the Tansy (Tanacetum vulgare) ; hence we 

 are led to infer that the larva of Cleodora Cytisella, which
