from the ventral region of the abdomen, the under-side of the thorax, and beneath 

 the head from the hinder part of the basal joining of the upper maxilla, is not 

 advanced by Mr. Balfour. 



In fig. 188 A, illustrating aquatic respiration (after Gegenbaur) the original 

 author's blunder over the name of the insect has been reproduced. The figure is a 

 sketch of the abdomen of a nymph of Cloeon rufalum (the Chloeon dimidiatum of 

 Lubbock's writings), the species being precisely indicated by a peculiarity in the 

 form of its tails, whereby it is distinguishable from the other German species of the 

 genus. It is named, however, Ephemera vulgata, an error which might have been 

 avoided by reference to Pictet's Monograph. It is adding insult to injury to give 

 bad names to an insect that has been subjected to the miseries of being drawn alive 

 under the microscope ; but it is a way some people have of showing their contempt 

 for creatures not so large as whales, and not so small as mites. Very likely Gegen- 

 baur, in the present instance, was misled by Wagner in " Isis " for 1832, pi. ii, 1. 



Reasons are given (p. 376) for considering the antennae to be unrepresented in 

 Arachnida, the chelicerae being homologues of the mandibles, the pedipalpi answer- 

 ing to the 1st maxilla?, and the 1st pair of ambulatory limbs to the 2nd maxillae of 

 Insecta. The telson is reckoned as a segment. — A. E. Eaton.

Gabriel Koch. — On the 22nd January, 1881, in the 74th year of his age, this 

 Frankfort Entomologist departed this life. He had amassed a very fair collection of 

 Lepidoptera, and from time to time had published sundry memoirs on this Order of 

 insects — of these by far the most interesting is the 8vo volume of 154 pages, which 

 appeared in 1854, on the Geographical Distribution of European Lepidoptera in 

 other parts of the globe : " Die geographische Yerbreitung der europaischen 

 Schmetterlinge in andern Welttheilen, nebst statistischen Tabellen." This work was 

 noticed at the time it appeared in the Entomologist's Annual for 1856, p. 153. 



In 1856, Koch published a larger work extending to nearly 500 pages : " Die 

 Schmetterlinge des sudwestlichen Deutschlands, insbesondere der Umgegend von 

 Erankfurt, Nassau und der Hessischen Staaten, nebst Angabe der Fundorte und 

 Flugplatze." A work which no doubt has proved very useful to many a young 

 collector in Western Germany. 



His latest publication on the geographical distribution of Lepidoptera appeared 

 in 1870, in Petermann's " Mittheilungen," as appears from the 8th volume of the 

 Eoyal Society's Catalogue of Scientific Papers.
