218 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



in considerable numbers in a certain loch in Scotland, about 

 a thousand feet above the level of the sea, and about one acre 

 in extent. It is so shallow that a man can wade through it, 

 and has a stony bottom, with a few weeds. Although sur- 

 rounded by other lochs, the tailless trout were found exclu- 

 sively in the one in question. The precise nature of the mu- 

 tilation was not given in the article. 



It was stated, in the discussion w T hich ensued upon the ex- 

 hibition of this specimen, that in other localities in Great 

 Britain there were streams in which trout without tails, and 

 sometimes without other fins, were not uncommon. 18^4,

INSECTS IN HAILSTONES. 



During a recent meeting of the Entomological Society of 

 London an insect known as Chlorops lineata was exhibited, 

 which had been found frozen up in the centre of a hailstone, 

 proving that it must have been flying at a very considerable 

 height in order to have been inclosed in the mass of ice. 3 (7,

PECULIARITIES OF MADEIEAN ENTOMOLOGY. 



* The entomology of the island of Madeira, according to Mr. 

 Wollaston, presents some very peculiar features as compared 

 with that of the main land, this being especially the case in 

 regard to the coleoptera. From a review by Mr. Wallace, in 

 Nature, of the paper of Mr.Wollaston, we learn that the most 

 striking facts indicated are : first, the affinity of the Madeiran 

 with the Mediterranean fauna ; second, the total absence of 

 certain large divisions of coleoptera abundant in that fauna; 

 third, the number of new and peculiar species and new and 

 anomalous genera ; and, fourth, the unexampled preponder- 

 ance of apterous species. This characteristic is exhibited, 

 very strikingly by the fact that species are apterous in Ma- 

 deira which are winged elsewhere ; also, that genera usually 

 winged embrace apterous species only in Madeira ; and, again, 

 by the presence of peculiar or endemic apterous genera, some 

 of which have winged allies, while others belong to groups 

 wholly apterous. This shows, evidently, according to Mr. 

 Wallace, that there is something in Madeira which tends to 

 render wings rudimentary, and Mr.Wollaston himself sug-
