 during the year of 1897: 40 are named, giving title, place and time of 

 publication, and a summary of content?. 



Elm-leaf beetle. (Country gentleman. Jan. 7, 1S97. 62 : 7, col. 4, 

 27 cm)« 



Corrections to an article on this insect from a correspondent of this 

 Journal, on p. 1,003 of the i)receding volume, as for example: there is no 

 such form of insect as 'the egg larva; ' the eggs are not infinitesimal in 

 size;' they are not placed on the ground with fine atoms of earth 

 intervening, but upon the leaves of the tree; the grubs do not descend 

 from the tree and hunt out the eggs in the soil for the purpose of covering 

 them with a protective secretion, and afterwards ascend the tree; it is 

 not true that only the larva that hatch out late in the season becom.e 

 beetles ; the eggs (on the leaves) can not be destroyed by treating the 

 soil at the base of the trees ; bands of cotton about the tree trunks could 

 not serve to prevent the grubs from ascending. 



Two insects. (Country gentleman. Feb. 11, 1S97. 62 : 106, col. 4, 8 cm) 



To an inquiry if the warble fly of England is identical with our ' buf- 

 falo-fly,' and when it first appeared in England, answer is made, that the 

 European warble-fly is Hypoderma bovis DeGeer, while that of the 

 United States is Hypoderma lineata Villers. The European species was 

 named about 150 years aso, and our species, till about 15 years ago, was 

 regarded as identical with it. H. liucata is known to attack the buffalo 

 in the west, but the so called 'buffalo-fly' is the one coiTimonly known 

 as the 'horn-fly,' Haeniatobia serrata Rob.-Desv., first noticed in this 

 country in 1886.
