is another black mark, but triangular in outline; and 

 on the ninth segment the subdorsal black stripe is 

 interrupted by a white spot, which extends somewhat 

 into the grey colour of the side, and along the side 

 run two dark brownish interrupted lines ; the head is 

 dark brownish-grey, lobed and freckled with black ; 

 the tubercles are grey or brownish-grey, and the tufts 

 of hair growing from them are of the same tint. (J.

LlTHOSIA STRAMINEOLA. 



Plate XLI, fig. 1. 



This insect, as previously recorded in the ' Zoologist,' 

 M. Guenee has pronounced to be a variety of L. griseola 

 after comparing the figure of the larva with preserved 

 skins of griseola in his possession. The larva was 

 depicted June 24th, and the imago appeared July 30th. 



The larva was brown, the head of a darker brown, 

 the back of the second, third, and anal segments 

 orange-red, as though the subdorsal marks had become 

 confluent ; a similar red mark, of an irregular trape- 

 zoidal figure, formed the subdorsal line on the anterior 

 two-thirds of each segment, a thin blackish line border- 

 ing them externally, a thin dark brown dorsal line, 

 interrupted on the second and third, and terminating 

 on the twelfth segment, tubercles and hairs brown.

From eggs of L. stramineola kindly sent to me in 

 August last by Mr. C. G. Barrett, I have lately suc- 

 ceeded in rearing four perfect insects, one male and 

 three females. Two of the females were yellow all over, 

 one of them having its wing somewhat clouded with 

 grey ; and the male was grey all over, in fact, a true 

 griseola. 



The correctness, therefore, of M. GrueneVs opinion 

 as to the identity of these two forms is completely 

 established, and stramineola must take the position
