A(^r. nebulosa : captured in plenty by Mr. Raddon, in July, near 

 Barnstaple, Devon. 



Agr. subgolhica : near Barnstaple, Devon, by Mr. Raddon. 



Agr. cursoria : this appears a coast insect ; I have received it from 

 Essex and the coast of Dorset. 



Agr. cinerea: taken in June; it has been found near Reading, 

 Berks ; in Kent ; and 1 have a female captured in the Isle of Wight. 



Agr. pascuea : I should feel obliged to any of your correspondents 

 who would, through your pages, give the habitat and time of appear- 

 ance of this species. — William Bentley ; 3, Critchell Place, New 

 North Road, July 8, 1842. 



210. Argyrosetia semifasciella. I have always beat this pretty and 

 distinct species from sallow in the month of June. I once found a few 

 specimens near Coombe Wood, but have taken them more plentifully 

 near Ringwood, Hants. — Id. 



211. Enquiry respecting the Caterpillars which feed on Cabbage. 

 Is not the green caterpillar which feeds on the cabbage the original 

 of the cabbage-butterfly ? Does it change its colours during its me- 

 tamorphoses, or are these two caterpillars varieties of one species ? — 

 Your answering the above questions will oblige your correspondent, 

 G. TV. Edginton, Surgeon ; Binjield, Berks, July 11, 1842. 



[There are three species of Pontia or white butterflies which feed 

 on the various species of cabbage, viz., P. Brassicae, Rapoe and Napi. 

 The largest of these, Pontia Brassicae, is produced from a caterpillar 

 of a greyish colour, with three yellow lines and black tubercles, it 

 feeds principally on the outer leaves of cabbages. The catei-pillars of 

 the two other species are green, and closely resemble each other ; but 

 P. Napi feeds more upon turuips and Cardamine 2^i'(^tensis than on 

 the common garden cabbages. The larva of a moth, Mamestra Bras- 

 sicae, is also very common on cabbages. — H. Doubleday^. 



212. Note OH Captures of Lepidoptera at Epping. I send you a 

 few remarks on the appearance of various Lepidoptera at E])23ing this 

 season ; although upon the whole the weather has been much warmer 

 and apparently more favourable, yet the number of insects has cer- 

 tainly been considerably less than last year. About the middle of 

 March Orthosia instabilis, stabilis, mundaand cruda, and Semiophora 

 gothica appeared, all, with the exception of O. munda, in tolerable 

 plenty, but their numbers were not to be compared with the multitudes 

 seen last sjiring. I captured two specimens of Calocampa cxoleta in 

 fine condition on the 16th of March: Towards the end of March and 

 during the first week or two in April, the nights were cold and i'o\y
