was the same, the mine was the same, and the mined leaves were of the same plant 

 as I had found in "Wisconsin, but, to my surpiuse, all the specimens that I have yet 

 bred differ so decidedly from the ordinary Q. Hermannella, that probably any 

 Entomologist would have considered, them, if only captured, as of distinct species. Yet 

 a little ingenuity, on comparison of the specimens, will show how the one pattern 

 of ornamentation is readily resolvable into the other. One who knows this ' Micro,' 

 or the figure of it before mentioned, will remember the silvery fascia dark margined 

 on both sides, the small silveiy spot before the fascia beneath the fold, and the 

 larger one just above the fold behind the fascia. Now, suppose the dark margins of 

 the fascia increased in quantity, especially the posterior dark margin ; then suppose 

 all the dark margin behind the fascia gathered on the costal margin forming a velvety 

 black spot 80 large that it touches the small silvery spot above the fold behind the 

 fascia ; in like manner, suppose the anterior dark margin of the fascia gathered 

 together in a velvety black spot before the fascia on the dorsal margin, large enough 

 to incorporate the silvery sjiot before the fascia beneath the fold ; then sujipose the 

 fascia widely interrupted in the middle : — and you have the variety. The costal par 

 of the fascia thus becomes the anterior silvery margin of a large velvety-looking black 

 costal spot, which, by its confluence with the silvery spot above the fold, appears to 

 be margined with silvery at that point, and sometimes has a few silvery scales 

 scattered through it ; and the dorsal portion of the fascia becomes the hinder silvery 

 margin of a large velvety-looking black dorsal spot, which, by its confluence with 

 the silvery spot beneath the fold, appears to be margined vrith silvery at that place, 

 and sometimes contains a few scattered silvery scales. Except that the quantity of 

 black and silvery scales is increased somewhat, the insect does not differ from the 

 old form. 



Miss Mary E. Montfeldt, of St. Louis, Missouri, informs me that she has found 

 only the variety there. St. Louis is also near lat. 38 deg., that is, nearly 3 deg. 

 south of Naples ; but then we are on the isothermal line of London, England, with 

 much hotter summers and colder winters. But whether climate has anything to do 

 with it is matter of conjecture. — V. T. Chambers, Covington, Kentucky, United

Entomological Society of London: \st March, 1875.— Sir S. S. Saundeks, 

 C.M.Q-., President, in the Chair. 



W. D. Eobinson-Douglas, Esq., of Castle Douglas, N.B., formerly a subscriber, 

 was elected a member of the Society. 



Mr. F. H. Ward exhibited living examples of a Lepisma distinct from L. 

 aaccharina, and unknown to Sir J. Lubbock, to whom they had been submitted. 

 They had been found in and about a bake-house in the neighboiu-hood of London. 

 Mr. McLachlan said it would be interesting to ascertain if American flour were used 

 in the bake-house, as the species might be identical with one of those recently 

 described by Dr Packard in America. Mr. Ward said he had seen the species from 

 Philadelphia. He also exhibited a set of microscopic slides illustrating the oeconomy, 

 &c., of the chigoe. 



Mr. Champion exhibited a well-grown individual of Empiisa patiperala sent by 

 Mr. J. J. Walker from Corfu. 



Mr. W. C. Boyd communicated some notes witl»rcfcronce to the fleas from rabbits'
