Being requested, at ratlier short notice, to contribute to the 

 " Annual," for the first time, any fresh information I may 

 possess on the non-aculeate Hymenoptera, I have limited the 

 subject to the above four families, to the exclusion of the 

 Tenthredinidce and ChalcididcB. Even after this deduction 

 about four-sixths of the order remain, comprising several 

 thousands of insects more or less obscure and unfamiliar, a 

 mass of material with which no one single-handed should 

 attempt to deal. Nor should I presume to do so, if it did 

 not appear that otherwise they would remain unnoticed, and 

 that the little I can effect is probably better than nothing. 

 If I could have examined, for the purposes of this paper, the 

 stores of unnamed specimens in my own boxes, the results 

 would have been more satisfactory. But the occupation of 

 compiling catalogues has for some time obliged me to attend 

 more to printed books than to the book of Nature ; and has 

 also required a diffiision of labour upon several subjects, 

 instead of the concentration favourable to progress. Hence
