shields; and an elliptical anal shield, wider than long, and pro- 

 vided with a transverse narrow crïbrated band. 



Epistoma. (Fig. 18). In stead of the two lateral cusps, the 

 epistoma is finely denticulate on the base of the median long 

 and pointed cusp. 



Mandibles like those of the female, 



Maxillae. (Hypostoma and palps) (Fig. 19). The inner malae 

 are truncated anteriorly, their junction forms in the median line 

 a truncated cusp provided with the two usual feathered appendages. 

 The outer malae horn-like, sessile. Of the palps nothing peculiar. 



The legs are short, shorther than the body. Those of the second 

 pair thick. Genu 3 and tarsus 4 are provided with a long tactile hair. 



Remark. Also the (ƒ and the Q have a transverse postanal crïbrum. 



8. Haeinogamasus hirsutus Berl. 



(With Plate V, fig. 20, and VI, fig. 21-32). 



Berlese tells us of this species that it has a soft skin without 

 any shields, except in the female, which has a distinct hairy sternal 

 region imitatiug a sternal shield and an indistinct hairy region, 

 where we should search for a genital shield. Berlese does not 

 mention the stigma nor the peritrema. 



I have examined several specimens found by Mr. S. A. Poppe 

 in a mole's nest, and am in the opportunity to correct these 

 statements. 



Fig. 20 (PI. V) represents the dorsal side of the body of a nympha 

 which has just thrown off its (probably protonymphal) skin. The 

 animal was very pale and very transparent and shows the fol- 

 io wing particulars. The body is broad oval. The vertex bears 4 

 hairs directed forward. There is a very thin (little chitinized) dorsal 

 shield, oval in shape, with top turned hindward; just before the 

 top the edges are somewhat bent inward. The whole animal in- 

 cluding this shield is very hairy, but there are two long and 

 three small spaces on the shield, which lack the villosity. I have 

 delineated them in my figure. Behind these bare spaces the shield
