of Guernsey and Sark.

The caterpillar feeds upon the cabbages and some other 

 plants in our gardens and fields, and in some seasons is quite 

 a pest. It is of universal occurrence in Guernsey and Sark. 



28.— Pieris Brassicse. (Large Garden White). Is very 

 similar to the preceding in marking, but is much larger. The 

 caterpillar almost invariably feeds upon our cultivated varieties 

 of cabbage and is often served up cooked with that vegetable. 

 Common in Guernsey and Sark particularly in May and August. 



It will be seen from the above list that Sark, although 

 much smaller, can boast of more species than Guernsey, 

 and not only that, but some of the rarer Guernsey butterflies 

 are comparatively common there. It is of the utmost im- 

 portance to science to obtain correct lists of all the insects of 

 the Channel Islands, but still more important results will be 

 obtained if the lists and insects from each island are kept 

 distinct. In collecting butterflies each specimen should be 

 labelled as soon as dry, with the date and locality of capture. 



In Ansted's Channel Islands, the species from Sark are 

 mixed with those from Guernsey. I find A. Aglaia (the Dark 

 Green Fritillary) and C. Pamphilus (the Small Heath) both in- 

 dicated in Ansted's lists as Guernsey species, but I have never 

 taken them here, nor have any of the collectors I have met with 

 here. A writer in Science Gossip, signing himself E. D. M. 

 says " Two species of butterflies A. Aglaia and C. Pamphilus I 

 have never met with in Guernsey, while in Sark they are com- 

 mon and many a sharp spin have I had through furze and fern 

 after the former.' ' 



P. Alsus (the Bedford Blue) is also named on Ansted's list 

 as a Guernsey species, but as very small specimens of the 

 common blue often occur I think that one of these must have 

 been mistaken for the former. One species of the skipper 

 butterfly is recorded on the same list from Guernsey and 

 another from Sark. This must also be a mistake as from their 

 peculiar flight, they would not escape notice. I have taken 

 both species in J ersey.
