NOTES AND OBSERVATIONS. 2B3 



of the pupa and the necessary width between the ends of the silken 

 band attaching it to the wood of the cage preclude any idea of it 

 a,ttaching itself to the stems of the food-plant, whicli "are extremely 

 fine and wiry. Another fact : I find that its silken attachments to 

 wood are very easily detached — i. e. the gummy silk does not stick 

 well to wood. On the other hand, two larvae which escaped and 

 pupated on the cement wall of our rooms were far less easy to detach 

 from the wall than from the cage. There may or may not be some- 

 thing in this. I give it you for what it is worth. — C. E. Morris ; 

 St. Etienne-de-Tinee, September 1st, 1919." 



Historical Note : Nicholas Gwyn. — When he was collecting 

 insects about Ipswich some years ago Dr. Phihp Brookes Mason told 

 me he conteniplated the compilation of a chatty book on entomo- 

 logical personalities, and I was much disappointed to hear, while on a 

 visit to Burton in 1901, that he had abandoned the task as too arduous. 

 But some day (when much of the most valuable material is irre- 

 trievably lost) a chronicler will arise and give us a word-picture 

 worthy of the Victorian and earlier pioneers of our science. Mean- 

 while the Editor of the ' Entomologist ' will heartily welcome 

 exclusive information upon this subject, which has never yet received 

 the attention it deserves — e. g. how slightly was Mr. Sheldon able to 

 associate Henry Tibbats Stainton, F.E.S., with his favourite hunting- 

 ground at Mickleham in ' Entom. Eecord,' 1919, p. 31. And Stainton 

 did not die till December 2nd, 1892. Thei'e is, then, small wonder 

 that the pronominor of Andrena givynana should nowadays be 

 utterly forgotten amongst us. This bee was so named by William 

 Kirby in ' Monographia Apum,' 1802, ii, p. 120 : " Memorise botanici 

 periti, tum et naturae scrutatoris indefessi, mihi at omnibus Historiae 

 Naturalis cultoribus semper amicissimum se praebentis, Nicolai 

 Gwyn, M.D. Gippovicensis, hoc insectum dicatum volo." It is, 

 however, remarkable that he is not referred to among Coyte and 

 other Suffolk entomologists at p. xvi of the preface of this work. 

 Nicholas Gwyn was a good all-round naturalist for his time and is 

 noticed as such in my ' Hymenoptera of Suffolk,' p. 13. We knew 

 he practised in Ipswich and that he died there in 1798, but I have 

 only just discovered exactly where he lived. In the ' Gentleman's 

 Magazine,' 1796, part ii, p. 913, is a note on the erstwhile mansion of 

 Sir Anthony Wingfield, executor to King Henry VIII, in that town, 

 M'herein we are told that "part of the building has served as a play- 

 house, and the family chapel opposite thereto is succeded by Dr. 

 Gwynne's house." That is to say that the mansion was on the 

 north side of Tacket Street, and the chapel, upon the site whereof 

 the doctor then lived, was on the south side of the same street, 

 almost or quite at the corner of the present Wingfield Street, whicli 

 branches out of it. Though Andrena givynana has stood in the 

 British list for over a century, the strict prtoritists are beginning to 

 threaten its perpetuity (c/. ' Ent. Mo. Mag.,' 1919, p. 10, nota) as 

 possibly synonymous with A. bicolor, Fab. We trust the change 

 will be averted. — Claude Morley. 



Stilpnid Ichneumons. — In continuation of my recent note upon 

 this interesting subject, it were well to record that I have received for
