irSG MODERN CLASSIFICATION OF INSECTS. 



Westio., from Java, in the elongated constricted prothorax and fine 

 blue colours, exactly imitates the Cicindelideous genus Tricondjla. 

 Stoll has figured a singular species, apparently belonging to this 

 family, under the name of the " Grillon aquatique cornu " (Henicus 

 Stollii, G. R. Gray); but it is quite evident, from the saltatorial 

 structure of the legs, and the impossibility of the insect executing a 

 leap under water, from the natural resistance of the element, that 

 there must be a mistake in the statement that it is aquatic in its 

 habits. 



The third and last family of the saltatorial Orthoptera comprises 

 the various species of migratory locusts, LocusTiDiE * Leach (Acrydii 

 Latr,), consisting of those species of the section of which the females 

 are destitute of an exserted ovipositor {fig. 56. 1. Locusta flavipes) 

 with the tegmina and wings deflexed, and the antennae short, filiform, 

 and cylindric, with from twenty to thirty joints (Jjff. 56. 8.), ensiform 

 (Jiff. 56. 19.), or clavate (Jiff. 56- 15.) The tarsi have only three 

 joints (fiff. 56. 12.), but the basal joint is longer than the others, and 



* BiBLioGR. Refer, to the Locustid^.
