to the Hemerobiidse, Panorpa communis and Bittacus Italicus, 

 and Hagenii, Brauer. The larvae of the latter are extremely 

 interesting animals, being covered with large branching spines 

 like the caterpillars of some species of Vanessa (Vienna Zool. 

 Botan. Verein, 1871). 



The admirable series of illustrations of the larvae of Coleoptera 

 by Dr. Schiodte has been continued in the ' Tijdskrift,' of Copen- 

 hagen. 



We are indebted to Dr. Emile Joly, of Toulouse, for several 

 ''memoires" on the transformations of diflerent species of 

 Ephemeridae, published in the Bulletin of the Society of Natural 

 History of that city, vol. iv. 



The same gentleman has also published a curious memoir, 

 *' Sur un nouveau cas d'hyper-metamorphose constate chez la 

 Palingenia Virgo a I'etat de Larve," in the ' Annales des Sciences 

 Naturelles.' 



Naturalists have been long interested as to the real character and 

 relations of a small aquatic animal, figured by Geoffroy under the 

 name of the "Binocle a queue en plumet," found near Paris, which 

 had eluded all subsequent research. Latreille, however, obtained 

 specimens of an analogous animal from Madagascar (which I for- 

 tunately secured in one of my visits to Paris, and which are now 

 in the Oxford Museum), and on which he founded the genus 

 Prosox^istoma, in the 'Nouv. Annales du Museum,' t. 11, p. 23, 

 ranging it amongst the Branchiopodous Crustacea. An elaborate 

 memoir on the French species of this genus by Messrs. N. and E. 

 Joly have led them to the conclusion (upon grounds which I have 

 not space to detail) that the animal is an insect, and that it is 

 most nearly allied to the larvae of certain Ephemeridae (' Annales 

 des Scienc. Natur., tom. xvi.) 



A summary of the memoir by Dr. Joly on the genus Prosopistoma, 

 regarded by him as the immature state of a species of Ephemeridae, 

 has also been published in the ' Memoires de la Societe Nationale 

 des Sciences Naturelles de Cherbourg,' tome xvi.) 



We are indebted to M. C. Kitsema, of Leyden, for an interesting 

 memoir on the transformations of the common flea, treated in a 

 popular manner, and published with illustrations in the ' Album 

 der Natuur' for 1872.
