 Pragse, 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 having 

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

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

 Desmazierii a plant altogether unlike that figured under that name 

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

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

 an undescribed species, Sp. Hugelii,

 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 Melittce of Kirby, or
