* The observations on this class of animals are especially recommended to such natural- 
ists as are situated in the neighbourhood of large rivers, or on the sea-coast. 
+ This species is inserted as being in M. Quetelet’s original list: in England it is rare, 
and not often met with. 
+ In this species the commencement of the stridulous cry of the male should be especially 
noted. 
§ As the species of this genus strongly resemble one another, and appear much about the 
same period of the summer, it will be sufficient to notice the first appearance of the genus only. 
Note.—It should be borne in mind that the names dcrida and Locusta are differently 
applied by the continental entomologists; the genus here termed dcrida being with them 
Locusta, and Locusta their Acridium. 
\| Note here, as in the case of Locusta, the first appearance of the genus only. Under 
Formica, mark, besides the first coming abroad in the early part of the year, the period of 
the summer or autumn when the winged ants migrate.
