40 THE ENTOMOLOGIST. 



Durham, but it occurs in tiie upper parts of both Tees, Wear 

 and Derwent Valleys, as well as on the Magnesian Limestone on 

 the coast ; it likewise grows on the Coal Measures not far from 

 Birtley. In the last locality no juniper insects have been detected 

 except Lachnus juniperi and Oligotroplius junipermus, but almost 

 certainly the other localities have supported, or do support, 

 Thera simulata. I say advisedly " have supported," because the 

 juniper has practically vanished for some unknown reason from 

 the coast, and no captures of the insect had been reported for years 

 until I captured a single example in 1914 at Black Hall Eocks. 

 My friend Johnson has netted it on Stanhope Moor, which 

 appears to be an addition to the known localities, unless it be 

 the same as that otherwise called " Wolsingham " in Robson's 

 Catalogue. 



Larentia ccesiata, Lang. Quite a common insect on all of the 

 moors in Durham, Northumberland, providing they are not too 

 low-lying. The larva is a much more general feeder than sup- 

 posed, and it can be beaten from, or collected from. Erica tetralix, 

 E. cinerea, Calluna vulgaris, Empetruvi nigrum, Salix repens, 

 Vaccinium myrtillus and V. vitis-idcea. In degree of melanism 

 exhibited, those from the Cleveland moors far surpass those sent 

 out in such profusion from Scotland, which more nearly approach 

 those I have seen in multitudes resting on the fences crossing 

 Whitfield Fell in West Allendale, Northumberland. 



Cheimatohia horeata, Hb. Somewhat local with us and very 

 patchy in its special haunts, although plentiful where it does 

 occur— Lonsdale, Cleveland ; Ebchester, Northumberland ; Hur- 

 worth and Chopwell, Durham. 



Acidalia divudiata, Hufn. Neither in Scotland nor in the 

 north of England can this be described as other than rare. I 

 have noticed it at Birtley, Durham ; on ragwort both at King- 

 horn, Fifeshire, and Forres, Elgin. Very plentiful and variable 

 along the Orriter Road, Cookstown, Tyrone, and near a village 

 (which I couldn't find !) known as Mackuey in the same vicinity. 



Amphidasys betularia, L. Not uncommon wherever I have 

 collected in Great Britain. Black and dark intermediates (never 

 the tvpe) in Durham ; black in Nothumberland ; black in the 

 neighbourhood of Middlesbrough ; black and intermediate on 

 Eston Moor ; type in Lonsdale — all three localities in Cleveland ; 

 type at Kippen in Stirling and Forres. 



Himera pennaria, L. Sparingly at Eston, Cleveland, on 

 larch, Lonsdale on alder, Easby Wood on oak; in Durham in 

 the Derwent Valley on oak, alder, birch, Calluna, etc., the last- 

 named being to me a very unusual food plant. 



Notodonta treniula, CI. Sparingly everywhere in Durham, 

 Northumberland and Cleveland, even on poplars in the streets 

 of large towns such as Middlesbrough and Gateshead ; also 

 taken at gas-lamps at Forres.
