TRÄGÅRDH, TWO ]MYRIOPODOPHILOUS ANTEBNOrHORTN.E. 21 



011 which I searched for them and it is the same in the case of 

 the 5 hitlierto knoAvn myrmecophilous Antennophorince and of 

 the one found on Scolope7idra. This can not possibly be a 

 mere coincidence, but seems to me to pro ve sufficiently, that 

 only the adiilt and not the ifnrnature forms live upon the myrio- 

 poda resp. the ants. 



4. Therefore the fact, that the present nymphae Avere found 

 not on the JuHdse but amongst decayed leaves, cannot be used 

 as evidence against my theory. On the contrary, as the 

 immature forms do not Hve on the Juhdae, the first places 

 where one should look for them, are Avhere the Julidse are 

 to be found, viz. amongst decayed leaves in the bush. 



5. Therefore the nymphse must be the immature forms 

 either of Neomegistus julidicola Tgdh or of Paramegistus con- 

 j rater Tgdh. 



6. A comparison draAvn betAA-een the three different forms 

 elicits the folloAving fäets . 



A marginal shield is present in Neomegistus and the trito- 

 nympha, Avhereas it is missing in Paramegistus. 



The ^ genital aperture is situated betAveen coxse II in Neo- 

 megistus and the tritonympha, Av^hereas in Paramegistus it is 

 situated on a line draAvn betAveen coxse III and IV. This fact 

 must be emphasized, as it is Avell knoAvn that the far forward 

 situation of the J" genital aperture is a secundary character, 

 and, it Avould be very remarkable if the nymphae should exhibit 

 a more secondary character than the adult forms, as Av^ould 

 be the case, if the nymphae belonged to Paramegistus. 



Of the four pairs of liypostomatic liairs tAA^o pairs are spe- 

 cially modified in Neomegistus and the nymphae, Avhereas in 

 Paramegistus only one pair is shaped differently from the others. 



Both digiti of the mandibles are of the same length in both 

 sexes of Neomegistus and the nymphae ; Avhereas in Paramegistus 

 the digitus mohilis exceeds the digitus fixus by one third of 

 its length. 



The la.st joint of the inaxillary palps in Neomegistus and 

 the next last joint of the nymphae (A^hich corresponds to the 

 last one of the adult forms) are narroAv and elongated, Avhereas 

 in Paramegistus the last joint is comparatively broad and short. 



Femora I of both Neomegistus and the nymphae have an 

 interiör ro av of four larger bristles, Avhereas in Paramegistus 

 the femor and genu I have one larger bristle each.
