EUPITHECIA SUCCENTtJRIATA. 23 



of food in this way, and became full-fed after they had 

 moulted two or three times. 



On the 2nd of October Mr. Hellins tried mugwort 

 beating again to find me a small pug larva [Eupithecia 

 innotata] like I have described in this volume [i. e., 

 Note Book IV] at page 220, but, though not suc- 

 cessful in that, he took more E. succenturiata, and 

 kindly sent me a dozen of them, amongst them being 

 some almost full-fed, and several full-grown. 



The mugwort which yielded the larvae of E. suc- 

 centuriata grows on sandy soil. (William Buckler, 

 November, 1883; Note Book IV, 192.) 



EUPITHECIA PLUMBEOLATA. 



Plate CXXX, fig. 5. 



During the course of last summer (1865) I had the 

 pleasure of examining a very beautiful and carefully 

 executed collection of drawings of various species of 

 geometers, their larvas and food-plants. These draw- 

 ings were the work of a very painstaking Continental 

 entomologist, M. Carl Plotz. 



This gentleman figured the larva of Eujpithecia 

 plumbeolata Haw., feeding upon the flowers of the 

 purple cow-wheat, Melannpyrum arvense L. This plant 

 is not very common in Great Britain ; another species, 

 however, M. pratense L., is much more frequent. 

 Finding that this latter plant almost invariably grew 

 in some plenty in those localities where Eujpithecia 

 plumbeolata was most freely taken, it occurred to 

 myself and several other entomological friends that 

 the larva might very probably be found to feed upon 

 its flowers. I am happy to say that our suspicions 

 have proved correct. Towards the end of June I 

 received a few eggs of E. plumbeolata from Mr. J. B. 

 Hodgkinson of Preston, Mr. C. G. Barrett of Hasle- 

 mere, and Mr. George Baker of Derby. The parent 

 moths were all taken flying over or among Melampyrum
