mthiops, ¥., found in great abvmdance in flood refiise on the banks of the Spey ; 

 (fe) Criocephalus rusticus, Dej., taken in niimbers in the stumps of, and in small 

 standing Scots fir trees in pine woods, swept over by a forest fire some few years 

 ago ; and (c) Zeugophora turneri, Pow., beaten in great profusion from aspens 

 growing near Loch-an-Eilan. Mr. W. C. Crawley, a colony of the ant Lasius 

 niger which had accepted as qxieen a ? of Lasius umbratus in 1908. Up to this 

 aixtiunn the only ants whicli had come to maturity in the nest were pure Lasius 

 niger, thus confirming Reichenbach's experiments that Lasius niger $ s are able 

 to prodiice ^ s parthenogenetically. In connection with Mr. Crawley's exhibit 

 Mr. H. St. J. Donisthorpe exhibited ^ <? , winged and wingless 9 9 and $ $ of 

 Lasius niger and L. umhratus for comparison. He remarked that unibratiis was 

 a scarce but widely distributed ant of considerable interest. Mr. Donisthorpe 

 also exhibited ^ ^ , winged and wingless $ 9 , and $ ? of Lasius fuliginosus, 

 and pointed out that it was now proved that the 9 9 of this ant often foixnded 

 their colonies with umhratus. Mr. W. J. Kaye, specimens of Eueides pavana 

 (Heliconidse), Actinote thalia (Acrxidae), and Dismorphia actinote from S. Brazil. 

 Comment was made as to the very close resemblance between the first two. 

 The resemblance was greatest on the vmder-side, but the upper-side also showed 

 considei-able convergence of coloiu-ing, The specimen of E. pavana exhibited had 

 been caught and papered by Mr. Kaye as an example of the common Actinote 

 thalia. The specimen of Dismorphia actinote caught on the Corcovado at Rio 

 de Janeiro, was shown principally as a mimetic species, for which a sharp 

 look-otit was kept, while the much more convergent Heliconidx had been passed 

 over, because iinsuspected. The Dismorphia, while only a partial approach to 

 the Actinote on the upper-side, was extremely close on the under-side, with the 

 hind-wing brought well over the forewing in an attitude of rest. Mr. L. W. 

 Newman, examples of Ahraseas grossulariata, bred October, 1910, as a second 

 brood, including two fine ab. varleyata g $ ; also an interesting Lyca;na sup- 

 posed to be a natural hybrid between Agriades thetis (hellargus) J x Poly- 

 ommatus icarus, 9 , taken wild near Folkestone, on September 10th last, with 

 specimens of A. coridon, A. thetis, and P. icarus for comparison. Mr. G. T, 

 Bethune-Baker having examined this exhibit, gave it as liis opinion that the 

 butterfly was merely an aberrant form of Polyommatus icarus. Mr. Philip J. 

 Bari-aud, a case containing several series of a large form of Satyrus statilinus 

 from the Aurunci Mts., Southern-Central Italy ; series of Par^iassius mnemo- 

 syne var. frilhstofcri, from Mt. Petrella, Aurunci Mts., 9000 ft. ; series of Colias 

 edusa and ab. helice, from Formia ; a very small specimen of Gonopteryx 

 cleopatra, measiu'ing 37 mm., from Formia ; and foiir examples of a large form 

 of Pam-phila comma from Southern-Central Italy.
