If that were really the case, there would obviously be 4 pairs 

 of hairs on the sternal (= sterniti-metasternal) shield- 

 MiCHAEL liad, liowever, only delineated 3 pairs. As there were 

 no females in the collection, I asked J)^' Oudemans to let me 

 hâve one in exchange for another species, to which he kindly 

 consented. On examining the female, the fourth pair of hairs 

 was discovered, and it was thus proved that in Euryjjarasitus 

 the metasternal shields are fused with the sternal one, a 

 characteristic which is too important not to be included in the 

 generic diagnosis. 



The following additions to, and corrections in, the previous 

 descriptions are to be made. 



Nympha. 



The two posterior hairs of the posterior dorsal shield are 

 much longer than in Oudemans' spécimens, and, indeed, of 

 an unusual length, more than half the length of thebody; they 

 are flexible, whiplash-like (fig. 45), 



Ventral side (fig. 46), Sternal shield finely pimctured, 

 its anterior margin more strongly chitinized than the rest. 

 Endopodal shields well de veloped in the angles beween 

 coxee II, III and IV respectively, triangular, not fused with 

 the sternal shield, 



The stigmata are sm'rounded by a narrow peritrematic 

 shield ; the médian edge of the peritremata is wavy in the 

 basai part (fig. 50). 



The legs (figs. 51 et 52). Tarsi I are very plentifully provided 

 with tactile hairs at the top, and, above ail, ^vith numeroiis, 

 finger-shaped, hyalin appendages, resembling the sensillœ 

 found on the antennae of insects. The ambulacresof legs I 

 are fully as weU developed as in legs II to IV, and are of a 

 peculiar structure, unlike those of the adults. 



The claws are slender and straight for the greater part of 

 their length, curved alniost at a right angle near the top. The 

 supraunguinal lobe is large — radion one and half times the
