8o The Butterflies and Moths of Teneriffe. 



The fore-wings are dark ashy-grey, with bronze 

 markings, and have a pale golden mark in the middle 

 resembling the letter r. The hind-wings are brown, of 

 a lighter shade towards the base. It measures in ex- 

 panse about two inches ; the antennae are long and fine. 

 The larva, which is green with a yellowish stripe at the 

 sides, feeds on the potato and other low-growing plants, 

 and is found during the early spring months, and well 

 on into the summer. 



PLUSIA ERIOSOMA. 



This is the fourth species described here of the large 

 genus Plusia. It is a much brighter golden-brown 

 colour than the last described specimen, measuring about 

 one and a half inches across the wings. The fore-wings 

 are golden-brown, having two distinct gold spots about 

 the centre. The hind are of the same tint as the fore- 

 wings, darker at the margin, and shading off lighter 

 towards the base. It is found in India, but is not a 

 European species.
