CANNOCK CHASE, 1918. 255 



I was surprised to find a worn Scotosia rhamnata in a pine- 

 wood on Brindley Heath. 



Lygris testata was common, most specimens being of tiie 

 Yorkshire form. L. populata, common, showing no great 

 variation. 



Cidaria corylata, very common in Mansty Wood. 



Thera variata, on Brindley Heath, Cavan's Wood. 



Coremia designata was common in Mansty Wood and on alder- 

 trunks in the valleys. 



One example of Oporabia autumnata was taken in Shug- 

 borough Park. 



Mesoleiica ocellata was fairly common ; M. bicolorata very 

 common in all alder clumps, most of the specimens being of 

 ab. parvula. 



Perizoma affinitata, P. alchemillata, and P. Jiauofasciata were 

 all common in Mansty Wood from May to July. 



I Ijdriomena /areata was not at all plentiful, but 11. iinpluviata, 

 mostly of the infiiscata form, was abundant in the valleys and 

 i)y Pottal Pool. To find the larva of the latter examine trees 

 where the contour of the ground gives access to the higher 

 branches, or, if possible, a tree that has recently fallen. 



Eupithecia goosRensiata (uiinutata) is abundant on the moor ; 

 E. lariciata on Brindley Heath ; E. caMigata in Mansty Wood ; 

 Gyiii7ioscelis pumilata throughout the district. 



Chlorodystis curonata was taken in Mansty Wood and Birch 

 Wood, near Abbott's Bromley. 



Abraxas grossulariata : I did not see this species at all. 



Lomaspilis marginata was fairly common. 



Semiothisa liturata was common wherever the fir-trees were 

 numerous. 



Phigalia pedaria was normally common, some of the speci- 

 mens being abnormally large. This species could be taken in 

 good condition from January to the end of May. 



PacJiys stratdiia was very common in Shugborough Park, the 

 insects being large and heavily marked. Although many were 

 taken in cop., eftbrts to obtain fertile eggs were quite unsuc- 

 cessful. Of P. betularia I found a few larvae in various localities. 



Boarmia rcpandata was common, but devoid of notable 

 variation. 



T. bistortata was common, mostly of the delamercnsis and 

 similar forms. 



T. paiictularia was more [)lentiful in the valleys than I have 

 ever before seen it. 



Ematiirga atomaria, though abundant, was disappointing as 

 regards variation. 



Bupaliia piniaria common on Brindley Heath, all of the 

 northern form.
