(With Plate V, fig. 18 and 19). 



Male and female are well described and figured by Michael 

 (Journ. Queck. Mier. Club. ser. 2, v. 15, p. 260—268, PI. 16) 

 except as to the genital shield of the latter, of which I gave a 

 letter description in the Tijdschrift voor Entomologie, vol. 45, p. 

 XI and 30. 



In a material gathered in a mole's nest by Mr. S. A. Poppe, 

 I found a male, a female and a nymph. They were all very dark 

 coloured, almost reddish-brown, as if they had feel on blood (pro- 

 bably on Haemogamasus hirsutus). The nymph was amongst other 

 nyraphs imrnediately recognizable as a nymph of Euryparasitus 

 terribilis by its two long hairs on the posterior margin of the 

 posterior dorsal shield. 



Nymph. Length 1340 yt.. Colour straw coloured, occasionally 

 darker, or very dark. Shape like that of the female. Dorsal side 

 (Fig. 18). There are two dorsal shields. The anterior shield pro- 

 tects a little more, the posterior one a little less than the half 

 of the dorsum. Both the shields are provided with the usual hairs, 

 which are very fine, and of which the following may be men- 

 tioned : 6 vertical hairs, directed forward ; two hairs on each 

 shoulder, turned outward: one on the shield and one on the weak 

 skin ; one hair on each posterior corner of the anterior shield, 

 somewhat longer than the others; four hairs on the posterior 

 margin of the posterior shield, at least twice longer than the 

 others. On and before the shoulders the peritrema is visible, having 

 become dorsal, and reaching the iniddle of coxa 1. 



On the ventral side (Fig. 19) we may enumerate the following 

 features : a long sternal shield, surpassiug the coxae 4, provided 

 with 8 hairs, and touching the mentum; two small inguinal
