GREVILLE COLLECTION OF CHALCIDID^, ETC. 345 



One of the chief points of value in the Greville collection 

 lies in the fact that the specimens representing eleven of the 

 species are types, specially referred to by Walker in his 

 original descriptions ; while considerable value and interest 

 attach to the other specimens (with only seven exceptions) 

 through the words '■^ fide Walker " which are written on each 

 label. It is evident that Walker examined and named the 

 whole collection, and quite probable that in describing many 

 species he examined Greville's specimens at the same time 

 as those from other sources. Hence we may reasonably 

 conclude that these examples are possibly co-types, or at 

 least metatypes. 



Robert Kaye Greville was born at Bishop Auckland, 

 Durham, in 1794, and settled in Edinburgh in 1816, where he 

 died in 1866. He thus spent fifty years of his life in the 

 Scottish capital, and may be regarded as essentially a Scottish 

 naturalist. He is best known as an authority on Cryptogamic 

 Botany, and published several important works, both in his 

 own name and in conjunction with such men as W. J. 

 Hooker, J. H. Balfour, and others. An interesting recogni- 

 tion of his work is found in the fact that an important 

 magazine devoted to his favourite subject received the 

 title of Grevillea. Although Greville was an assiduous 

 collector of insects, I have been unable to find any article 

 on the subject from his pen, with the exception of a list of 

 beetles obtained in the Edinburgh district (^Magazine of 

 Zoology and Botany, vol i., 1837, pp. 494-495) and a short list 

 of insects occurring in the parish of Dalmeny {New 

 Statistical Account of Scotland, vol. ii., 1845, PP- 93"4)- 



Since our knowledge of the distribution of Scottish 

 Chalcididae and Proctotrypidae is extremely scanty, the list 

 which follows, old as it is, may serve as a nucleus to work 

 upon in the future. In any case it is probable that Greville's 

 specimens as a whole pre-date any other Scottish records of 

 these much neglected but none the less interesting and 

 important insects. For the sake of completeness, I have 

 included a few species taken at Twizell, in Northumberland. 



In the following lists the species are arranged in the 

 sequence adopted by Claude Morley in his Catalogue of 

 48 2 P
