DILEFIIILA. 35 



This species is of about the same size as D. galii. The 

 head, thorax, and abdomen are similarly coloured, but the 

 white lateral stripes and dorsal line are wanting. The antennae 

 are white, and the wings narrower and more pointed. The 

 ground colour of the fore-wings is ashy grey, speckled with 

 blackish. The costal area is dark brown, varied with green, 

 and shades into the light grey central area. The hind-wings 

 are rose-coloured, with a black base, and a black sub-marginal 

 band. The larva, which is uniform green, feeds oil sea- 

 buckthorn {^Hippophac rhamnoidcs). 



Stainton called special attention to this species as one likely 

 to occur on the south coast of England, where its food-plant is 

 common ; but this prediction has not yet been confirmed, and 

 as the moth is a South European species, scarcely known north 

 of Switzerland, where it is scarce and local, its presence in 

 England does not seem probable. It is double-brooded, the 

 moth appearing in June and September. It is said sometimes 

 to hybridise with the next species.
