the various anatomical characters of the group, and the classi- 

 ficational details are given, is followed by careful descriptions of 

 all the species, of which a great portion are represented in the 

 elaborate [plates, much care having been taken to ensure the 

 identification of many of the species insufficiently described by 

 Mr. Walker by carefully prepared drawings of the types in the 

 British Museum, made at the expense of the author. Followdng 

 in the steps of Herrich-Schatfer, great attention has been devoted 

 to the arrangement of the wing-veins of the different species 

 represented in the first seven plates of the work, the remaining 

 six plates being occupied with the figures of the perfect insects, as 

 crowded as possible. 



The second part of the Micro-Lepidopterous portion of the 

 work of H. von Heinemann and Wocke on the Lepidoptera of 

 Germany and Switzerland has appeared (Brunswick, 1877, 8vo, 

 825 pp. and 102 pp. of tabulation of species). 



Papers by Herr Ritsema and Mr. Dunning on the Genus 

 Acentropus have appeared during the year. 



A memoir on new Lepidoptera from South America ( Tortricidse), 

 by Dr. Staudinger, has appeared in the 'Yerhandluugen' of the 

 Vienna Zool. &; Bot. Society (vol. 25). 



A memoir by P. C. T. Snellen on the Eastern species of 

 Pyralidffi, forming the genus Oligostoma, is published in the 

 ' Tijdschrift v. Entomologie.' 



HEaUPTERA. 



An extended memoir on the Hemiptera-Heteroptera of the 

 Astrakan district — written in Russian, with characters of new 

 species in German(!) and fuller descriptions in Eussian — appears 

 in the ' Moscow Bulletin,' 1875, part S, occupying thirty pages. 

 The inconvenience of such a publication is very great, as, for 

 instance, we find the habitat, Sarepta, printed in Eoman type 

 on one page, whilst in the opposite one it appears as " Capenta." 

 Fourteen new species and several new genera are described. 



The following part of the same 'Bulletin' contains a more 

 extended memoir on the Russian Heteroptera, by the same 

 author, with a plate. 



Mr. Uhler has published a list of the Hemiptera of the region 

 west of the Mississippi River.
