August and in September. Mr. Maling too recorded it in the 

 Transactions for 1875, p. 282. In Durham I have no doubt 

 it is well distributed and common in most places, but the only 

 records I have are that Mr. Gardner found it freely both in 

 Castle Eden Dene and in Hezleden Dene, and that Mr. 

 Backhouse got it at Shotley.

Cerostoma costella. Staint. Man., vol. ii., p. 314.

Generally well distributed and common. It is given in the 

 "Manual" as being abundant at Newcastle-on-Tyne, and 

 occurring regularly at Darlington. Mr. Finlay found it all 

 over the Morpe'th district, but never very common. Mr. 

 Maling also recorded it in the Transactions for 1875, p. 282. 

 In Durham Mr. Backhouse took it at Shotley, and Mr. Sang at 

 Castle Eden Dene, as far back as 1854. Mr. Gardner has 

 subsequently taken it there as well as in Hezleden Dene. He 

 found it common in both places. 



78. G. lucella, Eab. 



Cerostoma lucella. Staint. Man., vol. ii., p. 314. 

 ,, ,, Meyr. Hdbk. Brit. Lep., p. 700. 



A very local and rather scarce species. No one appears to 

 have taken it in these counties but Mr. Sang, who got it at 

 Elders, near Darlington, in 1869, 1870, and 1871, according to 

 his diary. In the Entomologist's Monthly Magazine, vol. vi., 

 p. 170, he records the capture of this insect and says that 

 when beaten out of young oaks "by day they generally drop 

 straight down, but not towards evening." 



79. G. scabrella, Linn. 



Cerostoma scabrella. Staint. Man., vol. ii., p. 314. 

 ,, ,, Meyr. Hdbk. Brit. Lep., p. 699. 



A very local species, and apparently only occurring here in 

 the neighbourhood of Darlington. It is given in the " Manual"
