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 Q-egenbaur) the original 
authoi s blunder over the name of the insect has been reproduced. The figure is a 
sketch of the abdomen of a nymph of Cloeon rufulum (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 vutgata , 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 lias been subjected to the miseries of being drawn alive 
under the microscope ; but it is a w r ay 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. 370) for considering the antennae to be unrepresented in 
Araehnida, the chelicerae being homologues of the mandibles, the pedipalpi answer- 
ing to the 1st maxillae, 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 
I rankfort Entomologist departed this life. lie had amassed a very fair collection of 
Lepiclopte/ a, 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 Verbreitung der europaischen 
Schmetterhnge in andern Welttlieilen, 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 
Schmetterhnge des siidwestlichen Deutsclilands, insbesondere der Umgegend von 
Frankfurt, 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 18/0, in Petermann’8 “ Mittheilungen,” as appears from the 8th volume of the 
Royal Society’s Catalogue of Scientific Papers.
