additions to the Natural History Mnseuin, especially in the Entomological 

 Dei^artnient, and on the motion of Mr. G. T. Bethune-Baker, seconded by 

 Dr. Dixey, a i-esokition protesting against this appropriation was unanimously 

 passed, explanations of the disastrous conseqiiences to the Museiuu having been 

 given by Mr. C. O. Waterhouse and Rev. G. Wheeler, in addition to the proposer 

 and seconder. Mr. H. Eowland-Brown then moved that " If a depxitation be 

 appointed to wait on Mr. Eunciman with regard to this matter, the 

 OiRcers and Council of the Entomological Society desire to be represented on it." 

 This was seconded by Mr. Bethune-Baker and carried unanimously, and Mr. C 

 O. Waterhouse said that he ^vould see that it was made known in the right 

 quarters. 



Commander J. J. Walker exhibited, on behalf of Mr. Geo. Brown of Coat- 

 bridge, Lanarkshire, living specimens of Helophorus txiberculatus, Gyll., hitherto 

 exceedingly rare as a British insect These were taken by Mr. Brown at the end of 

 April, walking about on bare dry peaty soil on the moors near Coatbridge. 

 Mr. O. E. Janson, a new and remarkable Lamellicorn beetle, belonging to the 

 Cremastochilides group of the Cetoniidx, in which the anterior tarsi were 

 unmistakably six-jointed. The specimen was received in a collection made by 

 Dr. Bayon in Uganda, and sent to him for determination by Dr. Gestro, the 

 Director of the Civic Museum, Genoa. Mr. C. O. Waterhouse suggested that 

 it was probably an abnormal si^ecimen, six-jointed tarsi being so far unknown in 

 Entomology. Mr. G. C. Champion expressed conctirrence in this opinion. 

 Mr. A. Harrison exhibited a drawer of Delamere Forest Aplecta nebulosa, bred 

 last year from var. robsoni i^ and var. thonvpsoni 9 by himself and Mr. H. Main. 

 He said : " Only fifty moths were bred, 26°/^ of the grey form, 42°/^. of rohsoni 

 and 32°/q of thompsoni. This result quite negatives our idea that the form 

 robsoni was a heterozygote, or hybrid (so called) and that the gi'ey form and 

 thornpsoni were homozygotes, or pure. We had been led to this conclusion by 

 the resvilts previously reported as being obtained by oiu'selves and by 

 Mr. Mansbridge. From a large bi'ood, both parents robsoni, we had previoiisly 

 bred 25°/ogrey, ol"/^ robsoni, and 24°/^ thompsoni, obviously Mendelian proportions. 

 From several broods, both parents grey, we had bred only the grey form. From 

 the grey form crossed with thompsoni, Mr. Mansbridge had obtained only 

 robsoni, and from the grey form crossed with robsoni he had bred 50°/^^ robsoni 

 and 50°/o grey. The results obtained last year show that the jjroblem is not so 

 simple as we had supposed, and that it will reqtiire further experiments before 

 it can be solved." Mr. Donisthorpe, thi-ee ? ? of Lasius mixtus, Nyl., a race of 

 L. umbratus, Nyl., and a ? of the latter for comparison. He remarked that 

 there were only two pi-evious records of its captiu-e in Britain. He pointed out 

 the difference between this race and umbratus, and said it was probably widely 

 distributed. He added that Mr. Evans had sent him ? t' and ^ $ from the 

 Isle of Moy to name. Mr. H. Rowland-Brown brought for exhibition examples 

 of Agriades thetis (bellargus) ab. ? coelestis, Obthr., taken last August at 

 Dompierre sur-Mer, Charente-Inferieure. He said that so far as is known at 

 present, this brilliant form of tlie blue V is confined in Western Europe to the 

 west and south-west of France ; roughly speaking between tlie valley of tlie 

 Loire and the Gironde, where it occurs locally not infrequently ; tlie blue
