Cordulegaster annulatus 



has the superior appendages large, entirely bifurcate, they 

 are strongly notched on their interior margins ; the inferior 

 pair are of moderate width and length with notched apices, 

 the lateral pads are roughly cuneate in shape with a fine 

 membranous apophysis of a straight horn shape connected 

 with each. 



Epiaeschna heros 



has the superior pair of great length and size bifurcate to 

 the base, strongly angled at a third from that point, being 

 notched bluntly before the angle, then gradually expanding 

 into long spatulate apices which are fringed below with long 

 hairs and are shortly spined on their dorsal areas for the 

 whole length; the inferior pair are rather more than half 

 the length of the superior, broadish, slightly tapering to blunt 

 extremities, which are turned down and fringed with hairs ; 

 the lateral pads are somewhat cuneate, with the apex produced 

 into a blunt tip, a strongly haired lobe being attached to the 

 inner side of each. 



Of the Libellulidae I can but show two genera. 



Lihellula quadrimaculata 



has the superior appendages deeply bifiu'cate, hollowed 

 internally, broadish and gradually tapering to bluntish apices ; 

 the inferior appendages are decidedly shorter than the superior, 

 with the upper margin straightish and the lower well curved ; 

 whilst the apex or apices, as the case may be, are more or 

 less pointed, they may in other species be somewhat rounded 

 or squarish. This type of formation obtains in other Libelluline 

 genera that I have examined also. 



Sympetrum sanguineum 



has the superior appendages bifm'cate to the base, with 

 somewhat razor -shaped blades ; the inferior is bifurcate 

 basally to a quarter from the apex, when it becomes one solid 

 organ terminating in a blunt point ; the lateral pads are small. 



The Trichoptera bear a close resemblance in many characters 

 to the Lepidoptera. One organ, however, is very different
