publications 1846 and 1848; Notes in the Entom. 187 1, &c.); West- 

 wood; Halidayand others. The 4th vol. of Thomson's Hymenoptera 

 Scandinavise is devoted to the Linnean genus Pieromalus. In his 

 classical 'Introduction to the Modern Classification of Insects,' 

 published 1840, Prof. Westwood estimates the number of British 

 species as follows : — Chalcides, 8; Eurytomides, 54; Spalangiides, 

 14; Torymides, 73; Miscogasterides, 96; Onnocerides, 33; Ftero- 

 jnaltdes, 2,T(>'} Cleonymides, 4; Encyrtides, 155; Eidophides, 224; — 

 altogether 1037 British species; and he thinks that there are 

 probably 1500, These insects are exceedingly minute^ of 

 parasitic habits^ and very obscure. 



Their collection and preservation is referred to under the 

 heading " IchneumonidDe," p. 36. 



Our Yorkshire species have not as yet been examined 

 sufficiently by any entomologist for us to attempt a list. Mr. 

 Inchbald sent a gall-maker to Mr. E. A. Fitch, viz. : — 



Eurytoma hyalipennis? Galls on Ammophila arundi- 

 nacea, near Saltburn. 



Family CHRYSIDID^. 



A small group of very brilliantly metallic-coloured insects, 

 which have received such English names as Golden-wasps, Ruby- 

 flieSj &c. Conspicuous by their refulgent and resplendent colours. 

 In 1862 Mr. Frederick Smith wrote a Monograph of the British 

 species, which will be found in the Entomologist's Annual for 

 1862, pp. 82-104. Mr. Smith there enumerated 6 genera and 22 

 species, and these numbers remain the same in the Rev. T. A. 

 Marshall's Catalogue, published in 1872. In addition to the 5 

 species in the following list, which are all we are as yet able to 

 show for our county, I have seen an old record (circa 1835?) 

 of Hedychrum regium (? = Z^ lucidulinn, Fab.) at "Rufforth 

 Wood." 



Hedychrum roseum, (Rossi). One specimen near Wake- 

 field (Smith, Mon. Chrys. in Ent. Ann. 1862, p. loi).
