THE ENTOMOLOGIST. 267 



Machaon is easily found, and easily reared upon the common 

 carrot-top, upon which it thrives, and ultimately produces a 

 finer perfect insect than is to be found in the natural state, 

 probably owing in some degree to being less exposed to 

 bleak winds, generally prevailing in marshy districts. —

Hemigynoiis Specimen of Acronycta leporina. — Mr. Bond 

 exhibited a British specimen of Acronycta leporina, present- 

 ing a remarkable instance of dimorphism, the right-hand 

 wings being coloured and marked as in the variety known as 

 bradyporina (which at one time was considered a distinct 

 species), whereas those of the left-hand were entirely typical 

 of leporina. The body also partook of the two forms, being 

 divided longitudinally into two tints. 



The Common Hornet in Siberia. — Mr. Smith said that

 had induced him to examine specimens of the common 

 hornet, from Europe, Siberia, and North America, and he 

 found that individuals from these districts presented no 

 appreciable differences, and their specific identity was proved 

 by the genital organs being alike in all cases, whereas those 

 of the Asiatic V. orientalis differed considerably. 



Ravages of Locusts in South Australia. — Mr. C. A. Wilson 

 communicated the following: — 



" Some of the farmers in the North appear to have suffered 

 very seriously from the swarms of locusts that have suddenly 

 made their appearance there ; and during the past three 

 weeks the papers have been full of letters, paragraphs, and 

 articles, upon the scourge, which have traversed the colony 

 in force from the north, and attacked Adelaide in their march 

 southward. As the subject is one of deep interest to every 

 tiller of the soil, we collect the most important items of 

 information and comment for the benefit of our readers. The 

 'Register,' referring to the subject on December 19th, says: 

 — ' It will be remembered that, in alluding to the locusts in a
