20 ARKIV FÖR ZOOLOGI. BAND 3. N:0 28. 



The lower jaw is shaped nearly as that of the male. Only 

 it is narrower towards the end and provided with a more closely 

 set row of about 12 small teeth; lacinia of the same shape. 



The maxillce. (Fig. 22. Pl. I.) The hairs of the coxse 

 and maxillary lobes of the same shape as those of the male, 

 but as far as I have been able to see there are two pairs of bare 

 lobes on the maxillary plates, instead of only one pair in the 

 male. 



The legs are shaped like those of the male except that the 

 tarsi II — IV have got no chitinous projections. 



Distribution: On several Julidae, especially in the coast- 

 bush of Natal and Znluland October — May; found at Durban, 

 Amanzimtoti, and Mbonambi Missionary-station. 



Developemeiit and biology. 



The reasons, which induce me to consider the above (p. 

 11 — 14) described imma tur e forms as the deutonymphse resp. 

 tritonymphse generantes of Neomegistus julidicola Tgdh are the 

 f ollowing : 



1. The softness of the cuticle, which at the first glance 

 made me beheve them to be Prostigmata, and the fact, that 

 the mandihles of hoth sexes are exactly alike, groves that the ani- 

 mals, in spite of the presence of genitalia are not adult forms 

 hut nymphce generantes. 



2. During my extensive researches upon the acari of Natal 

 and Zuiuland, which were carried on in numerous, different 

 locahties and in all arthropods and nests of termites and ants 

 I discovered and which were extended över more than a year, 

 I have been unable to find more than two Antennophorince 

 viz. Neomegistus jididicola Tgdh and Paramegistus conf rater 

 Tgdh, both occuring on several Julidse. Therefore we may 

 safély look upon it as well stated, that only two Antenno- 

 phorince^ occur in Natal and Zuiuland. 



3. Ne ver were any immature forms, larvse or nymphse, of 

 the two Antennophorinse found on the hundreds of Julidse 



^ At Cape-town one Antennophorine, Physalozercon raffrayi Berl 

 is found on Plagiolepis custodiens. This form cannot howev^er be taken 

 into consideration here, even if it were found in Natal, on account of its 

 quite differently shaped genital shields and legs.
