confined to the immediate surroundings of St. Aubin's, Don Bridge, 

 and Bel Koyal. Two visits to St. Ouen's Bay, one to the neighbour- 

 hood of Gorey, and one to the north of the Island, viz., to Plemont 

 and Greve le Lee being the only longer expeditions 1 was able to 

 make. The list here given should therefore be very largely increased, 

 even for the species occurring in July. Altogether 129 species were 

 secured, and to these must be added seventeen recorded by W. A. Luff, 

 which I did not meet with, making a total record for the Island of 

 146 species. Of these, fifteen, viz., Scolia ^-punctata, Pompilus 6- 

 maculatus, fumipennis, pilosellus ?, Tachysphex, n. sp. ?, Sphex 

 flavipennis, Oorytes punctatus ?, Bembex rostrata, Sphecodes niyritulus, 

 Halictus scabiosce, II. brevicomis, Nomada similis, N. juscicornis, 

 Coelioxys brevis, Meqachile muraria, do not, so far as we know, occur 

 in Britain, neither have they been recorded from either Guernsey or 

 Alderney. 



The following comparative table of the species known as 

 occurring in the three larger Channel Islands has been formed from 

 the data already mentioned, so far as Jersey is concerned ; and from 

 the excellent lists published by Mr. Luff, in the Transactions of 

 the Guernsey Soc. of Natural Science for 1891 and 1899 respectively, 

 so far as concerns Guernsey* and Alderney. The comparison is far 

 from satisfactory, as the Jersey list mainly depends on my own efforts 

 in the three weeks of July which I spent there, and during which 

 time I gave up nearly all my time to collecting, whereas those of 

 Guernsey and Alderney are composed of species taken throughout 

 the season by Entomologists, whose other occupations must have 

 prevented them from pursuing their subject uninterruptedly. At the 

 same time the table may be of value, if only as a means of inducing 

 others to improve upon it. I have added a fourth column, to include 

 the species taken by me at St. Briac, in Brittany, in August, 1899, as, 

 although the time of year was a little later than that when the Jersey 

 captures were made, still most of the August species appear in July, 

 and it will give at any rate an idea of the relation of the fauna of this 

 mainland coast to that of Jersey. Out of the 61 species common to 

 St. Briac and the Channel Islands, 62 occur in Jersey, whereas only 

 30 are recorded from either Guernsey or Alderney. There can, how- 

 ever, be little doubt that many additional species will yet be found in 

 these latter Islands, as it seems probable that species common both 

 in the South of England and Jersey, of which there are many, will 



* To Mr. Luff's Guernsey list I have added four species, Colleles suceincta.fodient, Daviesana, and 

 Psithyrus campestris, taken by Mr. F. V. Theobald, the three species of ColUtts at Cobo, and the 

 Psithyrus at Gouffre.
