 should be looked for where there is an abundance of Ash.

A coast species, and generally found on sand-hills, where the 

 larva feeds on a number of low plants, hiding during the day 

 below the sand and coming up at night to feed. Mr. Maling 

 reports it from the ^Northumberland coast ; Mr. Eales as ' ' gener- 

 ally common on the coast ; " Mr. Rhagg at South Shields links ; 

 Mr. Backhouse at Seaton Carew. It is abundant on the sand- 

 hills at Hartlepool, and very easily reared from the larvae, which 

 closely resemble those of Tritici; in fact I have more than once 

 bred Valligera when I expected I had Tritici larvae.

Suffusa is not a very common insect in either county. It is 

 in the Twizell list ; Mr. Finlay found it in Coal Law Woods, 

 but not plentiful, Mr. Maling met with it in several places on 

 the Northumberland coast, and Mr. Eales reported it as generally 

 common on the coast. We take it at Hartlepool at sugar but 

 not every season, and never more than one or two. The only 

 inland record I have for Durham, is that Mr. Boss has taken 

 three at Bishop Auckland.
