248 CATAIOGITE OF MOTHS. 



The late Mr. Robson recorded it for Killingworth and Harnham 

 in Northumberland. Mr. Harrison writes, " very common 

 everywhere — larvae equally abundant," that is, in the Birtley 

 district ; it is equally common around Hartlepool wherever 

 speedwell grows. 



405. Pterophorus lithodactylus, Tr. 



Pterophorus lithodactylus. Staint. Man., vol. ii., p. 443. 

 Akicita lithodactyla. Meyr. Hdbk. Brit. Lep., p. 439. 



This species is given in the "Manual" as being common at 

 Darlington ; there is, however, no entry in Sang's diary of its 

 occurrence there. I have taken it freely at Black Halls, and 

 seen traces of the larvae in Hezleden Dene. 



406. Pterophorus pterodactylus, Hiib. 



Pterophorus pterodactylus. Staint. Man., vol. ii., p. 443. 

 Alucita monodactyla. Meyr. Hdbk. Brit. Lep., p. 439. 



A species of very general distribution and common in many 

 places. It is given in the " Manual " as occurring regularly at 

 Newcastle-on-Tyne and commonly at Darlington. The only 

 record in Sang's diary is "Castle Eden, Aug. 29th, 1858." Mr. 

 Harrison records for Birtley " odd ones." I used to take a few 

 specimens every autumn at sugar on the borders of Hezleden 

 Dene, but it was never common ; also occasional specimens on 

 the railway side. 



407. Pterophorus microdactylus, Hiib. 



Pterophorus microdactylus. Staint. Man., vol. ii., p. 443. 



Marasmarcha microdactyla, Meyr. Hdbk. Brit. Lep., 



p. 438. 

 A common species in Hezleden Dene wherever its food plant 

 ( Eupatorium cannahimim ) grows ; also on the railway side 

 above Hart Station.
