attention, and not being very numerous in genera and 

 species are not so difficult to study as other sections of the 

 insect world. There are excellent works on the subject, 

 including Saunders' " Aculeate Hymenoptera of the British 

 Islands," Sladen's " Humble Bee," and Donisthorpe's 

 " British Ants." The student will find in these works all 

 the information he requires on the subject, with admirable 

 figures and descriptions. The position of the Irish list is 

 at once shown by the fact that out of 316 British species 

 only 167 have been recorded from Ireland.
