ACULEATE-HYMENOPTEEA OF GUERNSEY. 351 



The genus Anthophora, of which we have two species, 

 are large and conspicuous insects. 



The genus Apathus are parasites of the Humble Bees, 

 and are very similar to them in colouring and appearance. 

 Of the two species found with us, A. rupestris accompanies 

 Bombus lapidarius and A. vestalis is attached to B. terrestris. 



We now come to the " Social Bees," which live in com- 

 munities comprising males, females and neuters. The genus 

 Bombus are the well-known humble bees. They construct 

 their nests of grass, moss, &c, and make use of ready-made 

 excavations in banks, hedgerows, and sometimes in walls, 

 where they form large communities. 



The genus Apis closes the list. It consists of a single 

 representative, the common hive bee, Apis mcllifica, which is 

 well known everywhere. 



The following list contains 95 species of . Aculcate- 

 Hymenoptera taken in Guernsey, to which I have added two 

 species captured in Alderney. It may be considered far from 

 exhaustive, as I have no doubt that with further careful 

 Avorking many more will turn up ; it is, however, the first list 

 of Hymenoptera ever published for Guernsey. 



In Ansted's " Channel Islands " a list of 25 species of 

 Aculcata is given for Jersey by Mr. Piquet. To this list I 

 have made 20 additions as the result of two or three days' 

 collecting there this season in not very favourable weather. 

 I have appended a list of the 45 Jersey species for the 

 purposes of comparison. 



I have to thank Messrs. E. D. and E. P. Marquand for 

 kind assistance rendered in the collection of specimens, and I 

 am deeply indebted to Mr. E. Saunders, F.L.S., who is at 

 present engaged on a most valuable and exhaustive work on 

 the " Hymenoptera-Aculeata of the British Islands," for his 

 great kindness in examining and naming most of the species.
