Boisduval's ' Icones ' there were three copies, which realised £3, 

 £3 3s. and £3 respectively, whilst the only copy of the same author's 

 'Chenilles' was purchased by the writer for £4 15s. Leach's 

 ' Butterflies of China ' sold for £4 10.5. The total realised was 

 £731 9s. 6d., which sum ought to have been doubled. A considerable 

 portion of the library was acquired, by the courtesy of the Misses 

 Chapman, for the Entomological Society, and this, of course, did not 

 figure in the sale.— W. G. Sheldon ; March 18th, 1922. 



KECENT LITERATURE. 



Catalogue of Indian Insects. Parti — Aervdidae (Tettigidae). By 

 T. Bainbrigge Fletcher. Calcutta, 1921. 



Here we have the first instalment of what promises to be a most 

 useful publication. In addition to the actual catalogue, which itself 

 contains a certain number of notes, we have a bibliography of Indian 

 forms, a short account of the family, and a key to the sub-families as 

 far as India is concerned. In all 169 species are enumerated, one 

 only of which, Tetrix (= Acrydium) bijyunctatus, Linn., is British. 

 This family is usually considered to be part of the family Acrididas 

 ( = Acridiidse or Acridiodea of most authors). If, therefore, these 

 grasshoppers, with no pad between the claws and with elongated 

 pronotum, are constituted a family in themselves, the name 

 Acrydidae, named from the genus Acrydium {—Tetrix), which appears 

 to be but an incorrect spelling of Acridium,* 'is rather confusing to 

 say the least. To raise the sub-family Tetriginae to the family 

 Tetrigidse (or Tettigidae) would seem to be preferable. W. J. L. 



OBITUARY. 



Lachlan Gibb died March 1st, 1922, aged 68 years : thus ran the 

 legend that we read when we laid him to rest in Charlton Cemetery 

 on a beautiful spring day such as he would have loved. A man of 

 wonderful energy, too great perhaps for his bodily strength, for he 

 was not a very robust man, he was throughout his life actively 

 engaged in business, yet he found time to devote to his two chief 

 recreations, his garden and the Lepidoptera, in both of which he 

 took a keen interest from very early days. He had considerable 

 business interests in Canada and spent some years of_ his life in 

 that colony, during which he made many " entomological friends 

 there, with whom he was enabled to keep in touch almost to the last 

 by reason of his visits to Montreal, which after his re-settlement in 

 this country it was his custom to pay regularly every year. 



Gibb made no profession of scientific study and it is doubtful 

 if he personally ever made any contribution to literature, although 



* Greek, 'A/cpi'e = a locust. Schrank and Zetterstedt use the correct derivative, 

 Acridium.
