Insects. 843 



Sp. 8. PERONEA SUBCRISTALANA. 



Var. 1. subcristalana. Somewhat similar to cristalana : differs in 

 the usual markings not being white : scarcely variable. 

 Var. 2. sequana. Similar, with a yellow dash. 



Sp. 9. Peronea striana. 



Var. 1. striana. Well known and described; the stria white. 



Var. 2. insidana. I did not capture this insect. Similar, with the 

 button white or cream-coloured. 



Var. 3. fulvostriana, D. Similar to striana, with fulvous markings 

 on the inner margin : nearly a distinct dash. 



Sp. 10. Peronea profanana. 



Var. 1. profanana, Fab. Cinereous, with tuft of scales of the 

 same colour. 



Var. 2. provittana, D. Similar, with a yellow dash. 



Sp. 11. Peronea semtustana. 



Var. 1. semiustana, Curt. Somewhat similar to the last species, 

 with the exception of a very dark or black patch above the button, 

 and touching the base. 



Var. 2. Bentleyana. Similar, with a yellow dash. 



Var. 3. semistriana, D. Similar to semiustana, with striana 

 markings. 



It will be perceived I have endeavoured to reduce the number of 

 species of this beautiful genus of Lepidopterous insects, but have not 

 sufficient specimens to assert the whole of them to be but one variable 

 species.* P. ruflcostana and P. cristalana are very dissimilar, and I 

 think the most circular method cannot assimilate them, — to do so, 

 the number of captures must, at least, far exceed mine. Great varia- 

 tions from the type are to be found amongst plants, but such are 

 generally the effects of art, whereas our insects are the genuine pro- 

 ductions of nature. There cannot be any objection, in my opinion, 

 to retain the names by which the varieties ? are known, and it would 



* This conjecture can only arise from their similarity in size. The usual mark- 

 ings attending them may, I think, justly be compared to the ordinary stigma attending 

 the majority of the full bodied moths. 



D. means, throughout, names that I have given. When the words striana markings 

 are used, I mean those similar to P. striana.
