IVAR TRAGArDH 



The maxillae are, as pointed out previously (p. 561), of a remarkable 

 shape. Their basal part is set off from the rest as a pair of narrow transverse 

 plates the bases of which are concealed underneath the edge of the hypostome. 

 These plates have a sculptured surface and are obviously mere thickened por- 

 tions of the maxillae, the function of which is as yet obscure. On these plates, 

 which meet in the middle, we find inserted both pairs of maxillary hairs; one 

 submarginal pair near the median angle is straight and points forwards, while 

 the other pair is inserted at the posterolateral angle, so that their base is hid- 

 den by the projecting edge of the hypostome; they are rather stout and curve 

 abruptly inwards towards the median line. 



The maxillae are thin, triangular blades, with rounded sides and a cutting 

 edge of one lateral stronger tooth, two smaller rounded teeth and then a con- 

 vexe, thin blade. 



The palps (fig. 14) have a very small triangular basal joint; 2nd joint 



with a sharp longitudinal ventral edge and 

 two fairly long tactile hairs in the middle 

 exteriorly; 3rd and 4th joint short, cylind- 

 rical, the former with one, the latter with 3 

 hairs, one on the inner, two on the exterior 

 side; terminal joint cylindrical in the prox- 

 imal half, the dorsal side sloping downwards 

 in the distal half to a narrow point. Dors- 

 ally in the middle a short, fingershaped pro- 

 jection with short bristle, at the top dorsally 

 the three usual short bristles pointing obli- 

 quely upwards, two ventral subterminal hairs 

 and further backwards 2 — 3 hairs. 



Ventral side (fig. 19) resembles much 

 that of Neoliodes vermmilatus Jacot, as re- 

 gards the general shape of the genital and 

 anal shields and their sculpture. There are, 

 however, some features wich are of a special 

 interest, since it seems that they are in difierent degrees present in all the 

 species of this genus although their presence has not hitherto been enough 

 emphazised. Thus at the back of coxa III there runs a narrow but very dis- 

 tinct ridge which begins at the exterior side a little in front of the coxa and 

 then curves obliquely backwards and inwards. Coxa IV has a similar very 

 distinct ridge which runs forwards on the exterior side of the coxa as far as 

 to coxa III. 



Epimera I with 3 short bristles, epimera II with only one median pair, 

 epimera III with 3 pairs and the space on the anterior side of the 4th post- 

 coxal ridges with 3 pairs and along the sides of the anal aperture 3 pairs. 



Legs (figs. 16—18) areolated; all femora with ventral, rounded, thin 

 blades in the distal half; tibia long and narrow, tarsi short with 3 claws of equal 

 size; tibia I distally and dorsally with short projection, carrying a tactile hair.
