Icones Fungorum hucusque cognito7-um. Tomus 4. A. C. I. Corda. 

 PragJE, 1840. 

 Our object in noticing the present number, which in point of exe- 

 cution exceeds even the two preceding, is to call attention to the ad- 

 mirable figure of Puccinia graminis, or mildew. It is far more com- 

 plete than that so often referred to of Bauer. Among the points 

 elucidated in the present number, is the very interesting one that 

 Asterophora is a mere parasite of the second order, its matrix ha\dng 

 perfect sporidia. The author does not seem to have access to many 

 well-known journals, or he would not have published as Sporocybe 

 Desmazierii a plant altogether unlike that figured under that name 

 in the ' Annales des Sciences Naturelles ;' neither would Spharia 

 Robertsii, Hook., of which an admirable analysis is given, appear as 

 an undescribed species, Sp. Hiigelii.

ENTOMOLOGICAL SOCIETY. 



January 4th, 1841.— The Rev. F. W. Hope, F.R.S., President, 

 in the Chair. 



The President stated, in reference to Mr. Schomburgk's memoir, 

 read at a jirevious meeting, that migrations of butterflies to a very 

 great extent had been repeatedly observed in South America, in- 

 stances of which had been recorded in Helme's account of Buenos 

 Ayres. 



Mr. Westwood corrected an error which had occurred in the 

 printing of a memoir relative to the Pediculus Melitta of Kirby, or
