TRÄGÅRDH; TWO MYRIOPODOPHILOUS ANTENNOPHORIN.^. 11 



The moutJi parts show the foUowing differences from those 

 of the male. 



The mandihles (Fig. 19 Pl. I) are slightly smaller and not so 

 strongly chitinized. The upper jaw is narrow and straight, 

 only curved at the top and provided with one large front tooth 

 and behind this one smaller tooth. The internal si de of 

 the jaw is along its whole lengtli provided with a narrow mem- 

 branaceous and verv finely teethed plate. On the dorsal side 

 near the level of the condylus is a short hair. 



The lower jaw is provided with a »lacinia» of the same 

 shape as in the male; its anterior edge is membranaceous and 

 finely fringed. 



The maxillce. The exteriör median hair of the coxae is shor- 

 ter than in the male, the interiör median hair is shorter and 

 not flat, the anterior pair is straight and hairy, not bare. 



The central projection oj the maxillary plates icithout the 

 hiäton like appendage of the male. 

 _ The legs. 



? Legs I. The four interiör bristles of the femur, especially 

 the first two are shorter and not so strong. 



Legs II and III. The tarsi withont the chitinous projec- 

 tions of the male. 



Distrihiition. On Spirostreptus sp. found at Stamford Hill, 

 Amanzimtoti in Xatal, Dec. — March. and at Mkosi in Zululand 

 at the end of October. 



Beside the adult males and females of Xeo7uegistus, which 

 w^ere found from the end of October until the end of February, 

 I found at the end of March in möss at Enons' Bush in Xatal 

 one deutonympha, one tritonympha inasculina generans and two 

 tritonymphce feminince generantes and at the end of June 

 amongst decaying leaves at Entendweni Bush in Zululand 

 one deutonympha, which I unhesitatingl}^ ref er to the same 

 species. 



Before giving my reasons for doing so I will give the des- 

 cription of the mites, and of the other myriopodophilous 

 genus.
