speckled wood) so abundant. Although a common species, 

 it is usually associated with wooded districts. In a note 

 published in the " Entomologist's Monthly Magazine," the 

 late Mr. R. McLachlan, F.R.S., noticing the abundance 

 of this species in Guernsey, suggests that at one time 

 these islands were much more thickly wooded than at present. 

 The Small Heath butterfly, C. pampkilus, is also abundant, 

 although it has only been once observed in Guernsey. 



During the Society's excursion to the island on June 

 loth, 1889, I found five nearly full-grown larvae of Malaco- 

 soma neastrza, the Lackey Moth, all feeding on bramble 

 leaves. They must have been abundant as the remains of 

 their webs were to be seen on the bramble bushes in different 

 parts of the island. Mr. Marquand found numbers of the 

 larvae again this year. One specimen only of this moth 

 has been taken in Guernsey. 



The form of Zygcena trifolii, the 5-spot Burnet moth, 

 found in Herm, is somewhat different to that occurring on 

 the Guernsey and Sark cliffs. The latter form occurs in 

 June and the former in late July and August. Mr. J. W. 

 Tutt, F.E.S., has named this variety sub-species palustris. 

 A precisely similar variety is to be found at the same 

 period of year on the marshes by the seaside at Cancale 

 and the Isles Chaussey between Granville and Cancale. 

 On August 11th, 1874, I bred a specimen, from a 

 pupa found in Herm, still bearing the head of the larva, 

 with not a trace of the antennae of the perfect insect. This 

 is a very rare form of monstrosity. 



The Coleoptera, or beetles, number 133 species, almost 

 as many as are recorded for the much larger island of 

 Alderney. The non-British Cetonia morio is not uncommon and 

 the beautiful rose chaffer Cetonia aarata has been taken, 

 but is not nearly so common as in Sark. Mr. Marquand 

 found three specimens of the pretty little Chrysomela polita, 

 a species not yet recorded for Guernsey. In an interesting 

 little book entitled " Rambles in the Channel Islands by a 

 Naturalist," a letter from Dr. F. C. Lukis to William 

 Yarrell, the celebrated naturalist, is quoted, in which the 

 writer states that he has found that rare beetle Nebria 

 Complanata in Herm, but has never seen it in Guernsey. 

 This species has not been found by Mr. Marquand or 

 myself, but being such a local insect it may still exist in some 

 unexplored spot in the island. 



Fifty species of the Aculeate-Hymenoptera (ants, bees 

 and wasps) have been taken. Twelve of these have not
