62 THE ENTOMOLOGIST. 



All the Noctuae above mentioned, P. chi and C. haworthii 



excepted, and a number of other species, were taken at ragwort. 



There is no other plant nearly so attractive as ragwort in this 



locality. We have, during the last few years, taken at least sixty 



species at its flowers. 



Many of the August insects continued to be taken in 



September. In addition we took larvae of — 



Orgyia antiqua Notoclonta dictsea 



Bombyx rubi N. dictseoides 



Platypteryx lacertula Agrotis porphyrea. 



Imagines of Orgyia antiqua, Agrotis agathina, and Xanthia 



ferruginea. 



During October and November, owing to the inclemency of 



the weather, we did very little entomological work; ivy Avas 



a complete failure. 



Cidaria miata Orthosia macilenta 



Agrotis suffusa O. lota 



A. saucia Anchocelis pistacina, 



usually pretty common, did not put in an appearance ; only a few 

 Cerastis vaccinii Calocampa vetusta 



Scopelosoma satellitia C. exoleta 



were seen. A few larvae of Acronycta j)si, and some pupae of 



Notodonta dromedarius, N. ziczac, and Ampliydasis betidaria were 



our only other captures during these months.
