He marks. The species reminds me in its shape of the 

 mucronai segment of A. longicornis but is well separated by 

 its shorter antennae and the occurrence of dental spines. 



One cannot be too careful when examining and drawing the 

 mucronai segment of the ApJiysa species as in different 

 positions of the object and at different degrees of magnification 

 one gets the most different pictures. One figure is given here 

 taken at normal magnification and two other ones taken with 

 use of oil immersion. In the first all dentes and lateral 

 processes are plainly visible.

Of this very interesting form there are two individuals 

 of somewhat different size. The segmental formulae are as 

 follows : — 



Diagnosis. Ant. 1=1 : 0.85. 



Ant. I : II : III : IV = 1 : 0.64 : 0.96 : 1. 

 Abd. Ill: IV=1 : 13.33. 

 Manubr : Mucrodens=l: 1.14. 



Eyes 8 + 8, arranged in two parallel rows. Thanks to the 

 thin pigment they are visible without the use of extra 

 methods. Their relative size I cannot fix. 



Antennae longer than half the body, in shape, colour, etc., 

 quite peculiar. Ant. I and II are thick and dark brown and 

 the two apical joints narrow and nearly pure white. 



All joints are covered with a bottom layer of brown feather- 

 shaped setae, which become shorter on the apical joint. Ant. 

 I and II are also provided with big tufts of strong brown plainly 

 serrated setae and from Ant. II and III some uncoloured long 

 setae of the same structure are seen extending in oblique 

 directed downwards. The two apical joints are furthermore 

 covered with fine vitreous sensitive setae, which are placed at 

 a certain distance and at right angles towards the joint. Upper 

 claw with pseudonychia, a proximal double tooth and a distal 

 simple one ; empodial appendix lancet-shaped. The tibio-tarsal 

 sensitive seta comparatively short, distinctly incrassate. The 

 two segments of furcula of the same length; dentes parallel, 

 slightly tapering downwards. On the internal side they are
