110 CATALOGUE OF MOTHS. 



A coast insect which appears to reach the limit of its northward 

 range on the Yorkshire coast. Two only have been captured in 

 Durham, to my knowledge, — one by the late Mr. Tollman and 

 another by the late Mr. Wasserman, both on the sandbanks south 

 of the river Tyne.

 Saucia has only twice been recorded in our district. It is in 

 the Twizell list under the name of cequa, but the specimens 

 were not in the collection. Mr. G. Boss, of Bishop Auckland, 

 has taken two specimens there. These are the only notices of 

 its occurrence that have reached me. It is an insect that, though 

 generally rare, occasionally appears in large numbers. It has 

 been taken in many parts of Yorkshire, from Scarbro' on the east 

 coast, where it is often plentiful, to Leeds in the west. It is 

 also found in Scotland, both east and west, extending even to 

 the Shetlands. It is often double brooded.

 Larva. 



Very rare in this district, only two records having come under 

 my notice. The first is that of the Twizell list, but the speci- 

 men was not in the collection when I had it examined. The 

 other was taken in 1874 at sugar in Loutan Pall "Wood, Upper 

 Teesdale, by P. A. Lees. I see no reason why it should not 

 occur regularly.
