NEW WORKS ON ENTOMOLOGY. 



FARM INSECTS ; being the Natural History and 

 Economy of the Insects injurious to the Field Crops of Great 

 and Ireland, and also those which infest Barns and Gra- 

 naries, with Suggestions for their Destruction. By John 

 Curtis, F.L.S. Price Ws. Blackie and Son. 



In this handsome volume of 528 pages, with 16 coloured plates 

 and numerous wood engravings, Mr. Curtis has given, in a collected 

 form, the mass of information on insects injurious to agriculture, 

 which had already appeared from his pen in the "Journal of the 

 Agricultural Society" and in the "Gardener's Chronicle." 



Mr. Curtis observes in the Introduction — " I commence with the 

 tui-nip crop, investigating the several species which live upon the 

 leaves, those which inhabit the flosveis, such as devour the seed, 

 and those which injure and destroy the roots. I then pass on to 

 the cereals, and investigate the iiistory of the insects which cause 

 abortion either by inroads on the flowers, or by reducing the su})j)ly 

 of sap to the germen ; of those which attack the folias^e, and of 

 such as cause the roots to perish. I next proceed to the barn and 

 granary and describe the beetles and moths, together with their 

 larvae, which subsist upon stored grain. I then enter the pea and 

 bean fields, where we are sure to find abundance of depredators. 

 Mangel-wurzel and carrots next occupy my attention ; and thence 

 I proceed to examine the potato crops, which afford a wide field for 

 inquiry among the beetles, bugs, &c., which live on their haulm, 

 as well as the larvae of various beetles, gnats, flies, &c., which in- 

 jure the tuber itself." The volume concludes with "an exami- 

 nation of the insects injurious to clover crops and pasture lands." 



The author observes, in his concludint; paragraph, that his object 

 has been "to make the farmer acquainted with the habits of his 

 insect enemies, and to enable him to recognize them under their 

 different aspects of egg, caterpillar, pupa and perfect insect."
