6. Uropoda ovalis (C. L. Koch). 



I |:;;ive here a more detailed desci'iption and a better figure than 

 are hitherto published. 



Length 0,485 mm. 



Nympha homeomorpha pedimculata. Shape oval ; dorsum convex , 

 smooth, with markings like those on the ventral plate (Jms.. 17) 

 and numerous minute hairs; only the border is flat , provided with 

 regularly placed minute hairs, like so many other Uropoda. The 

 most striking specific character is the strange peritrema. The stigma 

 is situated in the foremost part of the pit for the saving of the 

 third log. The peritrema extends on both sides of it : firstly straight 

 hindward within the said pit, ond secondly forward till near to 

 the head. This end first bends towards the border, then runs 

 along it, till the pit of the second leg. Here it bends inward, 

 running with a bow with the concavity turned towards the border, 

 on the bottom of the said pit ; when it has again reached te border, 

 it follows this up to the spot wliere the border suddenly becomes 

 very narrow. 



Six specimens hung on the body of Criocephalus ferns Kr. 

 (epihafa Schiödte). Found in Bremen, 31, 8, 1899.
