192 THE ENTOMOLOGIST. 



coloured map in six sheets and three plain maps, illustrating the 

 breeding-grounds, and showing the course of the migrations of 

 the grasshoppers and the natural characteristics of the regions. 



Altogether, these two reports on the destructive American 

 grasshoppers are one of the best exponents of how much is to be 

 learned about a single insect or group of insects. They can but 

 be very beneficially studied bj' all entomologists ; their practical 

 value must be immense ; the labours of the commission were 

 arduous, but the results arrived at are quite beyond expectation. 

 The United States Government generally and the members of the 

 commission specially, deserve to be congratulated on their 

 success. — E. A. F.

The Committee and Secretary of this energetic voung Society 

 are to be congratulated upon this series of Transactions. The 

 number before us contains several articles which will be found 

 interesting to our readers. The first we reprint in this number 

 of the ' Entomologist.' Another is that by Mr. Kaphael Meldola 

 upon " The Developmental Characters of the Larvge of the Noctuse 

 as determining the position of that Group." This paper is well 

 worth our reader's perusal, whether he may fully agree with the 

 whole of the theories advanced or not. Mr. English gives an 

 interesting account of " The First Night's ' Sugaring' in England," 

 which he further terms a " Reminiscence of Epping Forest in 

 1843." In this paper Mr. English claims to be the discoverer of 

 that mode of attracting moths now so universally adopted by 

 lepidopterists. The geological and anthropological sections are 

 illustrated by engraved plates. — J. T. C.

 Charles Lang, M.D., F.L.S. Part I. Four coloured

We have already noticed that this valuable work was in the 

 press, and it is now our pleasure to see the first part, which fully 

 confirms our expectations. The introduction is explicit, the 

 letterpress clear, and the plates are excellent. The circulation 

 is sure to be large. — J. T. C.
