226 HOMOfiOSOMA SINUBr.JiA. 



On the 6th of September, 1878, 1 received from Mr. 

 C k G. Barrett, who had taken them on the 4th, at 

 Tenby, Pembrokeshire, several root-stocks of Plantago 

 lanceolata containing some larvae of this species, 

 together with instructions to plant the roots in a pot 

 and to keep them growing or alive through the winter 

 and spring, and to expect the moths to emerge in the 

 following July. The two roots I tore open contained 

 each a larva, one full-grown or nearly so, the other 

 full-fed. 



The full-srrown larva when extended is about half 

 an inch long, very stout and plump in figure, tapering 

 from the fifth segment to the head, and also more 

 from the tenth to the thirteenth ; the segments are 

 deeply cut and have a deepish transverse wrinkle 

 beyond the middle ; the thoracic subdivisions are also 

 deep, the sides dimpled, and with an inflated puckered 

 ridge beneath the spiracles. The ventral and anal 

 legs are all short and quite well beneath the body. 

 Dimples also occur on the back. 



In colour the head is shining reddish-brown, 

 blackish at the mouth ; the plate on the second 

 segment is also reddish-brown at its hind margin, but 

 pinkish-brown in the middle and in front, and shining ;. 

 a small shining reddish-brown plate is on the anal 

 flap; the thoracic segments are tinged with a delicate 

 pinkish -grey, melting from them gradually into the 

 yellowish-white of the back, soft and smooth like a 

 white kid glove, but without gloss ; the tubercular 

 most minute dots are dark grey, each with a blackish 

 hair ; the round spiracles are brown ; in the deep seg- 

 mental divisions occurs a transverse streak of rather 

 shining grey on either side of the unmarked dorsal 

 region ; the wrinkles on the thoracic segments are 

 dark violet-grey ; the anterior legs are shining brown.
