cuneate in shape, dentate and pilose ; the hairy, lateral pads 

 are but little in evidence. 



Lestes rectangularis 



has a pair of superior appendages that are long, broadish 

 at the base, rapidly tapering half way, and then fairly uniform 

 to the bluntly hooked apex ; connected with these are a pair 

 of hairy sclerites whose ofl&ce I cannot understand, they are 

 oval, pad-shaped with hairy edges. The inferior appendages, 

 also paired, are not so long as the superior, and curved down- 

 wards ; the basal parts are fairly broad, and they gradually 

 taper to a rounded apex fringed with long hairs. 



The same variety of organs obtains equally among the 

 Anisoptera, in the Gomphidae. 



Onychogomphus forcipatus 



is well named, for its appendages are large and strong, the 

 superior pair are bifurcate to the base and are markedly 

 asymmetrical in their apices ; they are long, strong and a 

 third from the end are suddenly curved almost at right angles ; 

 the one apex is bluntly rounded, the other is longer and 

 terminates in a fairly sharply pointed tip; the inferior pair, 

 also bifurcate to the base, are more or less evenly curved, 

 with a strong projecting tooth near the centre, the apex being 

 the shape of a bird's head with a stoutish beak ; the ventral 

 lateral pads are small in comparison, but well developed. 

 These organs must have a most powerful grasp, and the 

 central tooth of the inferior pair seizing the face of the female 

 should produce a deep impression. 



Dromogomphus spinosus 



has the superior pair of appendages wholly bifurcate, 

 broadish and terminating in a longish triangular finely hairy 

 apex; the inferior pair form a dtep hood arising just below 

 the dorsum, extending frontally on the venter into a rounded 

 pad which assumes a pointed apex in one position ; the hood 

 is entirely cleft on the venter, the lateral pads are well developed 

 and strongly haired. 



Of the Cordulegasteridae and the Aeschnidae I can only 

 show one genus each.
