III. Insects of other Orders. By several Contributors. 



Five species of Odonata, two of Hymenoptera, and one of 

 Diptera were also captured Ijy Mr, Bennett : the first were kindly 

 named by Mr. E. McLachlan, r.R.S., the second by Mr. W. F. 

 Kirby, and the third by Mr. E. E. Austen. 



The Odonata were all common species with wide distribution, 

 and it is of interest that they should in this respect contrast so 

 sharply with the Lepidoptera Rhopaloeera and Araneidea, and to 

 a less extent with the Orthoptera. The contrast is probably to 

 be explained by the facilities for distribution which the Odonata 

 possess in their powers of flight. 



Mr. Bennett records that the Odonata are very numerous on the' 

 plains where streams abound. — E. B. Poulton.
