The Zoologist — September, 1874. 4163 



Mr. F. Smith exhibited some earthen cocoons found in a salt marsh at 

 Weymouth by Mr. Joshua Brown. They proved to belong to a dipterous 

 insect (Machaerium maritimum), one of the Dolichopidfe. They were 

 found lying on the wet, salt sand or mud, and mostly fell to pieces when 

 touched. 



Mr. S. Stevens exhibited specimens of Agrotera nemoralis and other 

 Lepidopterous insects from Abbot's AVood, Lewes. 



Mr. Butler exhibited a very rare book on butterflies, which he accom- 

 panied with the following remarks : — 



Notes on Lees ' Coloured Specimens to Illustrate the Natural History of 

 Butterflies' (London, 1806.) 



" The exceedingly scarce, if not unique, book which has recently come 

 into the possession of Mr. E. W. Janson has not hitherto been quoted in any 

 synonymic catalogue, and as it contains plates and diagnoses of no less than 

 nineteen species, it is important, now that an opportunity has occurred, to 

 record them at once. 



PI. I. Papilio Hyparete, Lee — (Delias) Eucharis, Drury. Lee remarks 

 as follows : — ' This specimen does not exactly answer the description of 

 Linnaeus, nor yet of Fabricius ; yet it comes so near to both that there is 

 no doubt of its being the same, either with some slight variation, or that 

 the colours of the specimen have in some degree changed. The yellowish 

 hue on the upper side of the anterior wings is described by them as being 

 white ; nor is any notice taken of the marginal flesh-coloured spots on the 

 extremity of the posterior wings. It will not, however, by any means 

 answer the description of the Eucharis of Fabricius: and Drury clearly 

 describes Hyparete, as given here, and as mentioned by Fabricius, under 

 the name of Eucharis. Linnaeus has no fly under the name of Eucharis. 

 The insect is in itself extremely beautiful and delicate, and when alive must 

 be very brilliant.' Fortunately the figure in Clerck's ' Icones' sufficiently 

 determines what the P. Hyperate [sic) of Linneeus is ; Fabricius, however, 

 confounded the two species together as Lee has done. Drury figured and 

 described his P. Eucharis in 1773; it was first described by Fabricius 

 in 1775. 



PI. II. Papilio Thersites, Lee = Papilio Turnus, Linn. Lee says : — 

 ' Respecting this butterfly, of which Fabricius gives so detailed a description, 

 Linnteus is wholly silent. It was either unknown to him or described 

 under a different name. Indeed it so nearly resembles the Papilio Machaon 

 of the latter that it may be considered as a variety of that fly.' The true 

 P. Thersites is so entirely distinct that the ' detailed description ' of 

 Fabricius seems to have been of very little use to Mr. Lee. I tliink our 

 American friends will hardly agree with his concluding sentence.
