26 IVAK TRAGÂRDH, (Schwed. Südpolar-Kxp. 



The palpi (Text-fig. 48); the second joint is much wider and more curved than 

 in E. niedioareolahis and the third joint is shorter than the second one, whereas in 

 E. medioareolatus they are of the same lenLjth; the terminal joint is slightly longer 

 than the claw of the fourth joint. Hairs of the palpi are simple with exception of 3 — 4 

 larger hairs which are serrated and situated on the dorsal side of the second joint, 

 near the front margin. 



The cuticle of the palpi as well as that of the maxilhe is thick and penetrated 

 by numerous, fine pores. 



The maxillc wholly fused together, forming a short rostrum, the length of which 

 is not twice its width at the base; rostrum anteriorly rounded, provided on the ventral 

 side with about 10 pairs of fine hairs (Text-fig. 50). 



The crista inetopica (Text-fig. 49) is finely punctured, not strongh- chitinized, 

 anteriorly square, not projecting as in E. medioareolatus; the part of the crista in 

 front of the posterior tactile hairs is twice as long as the part behind the hairs, whereas 

 in E. inedioareolatics the posterior tactile hairs are situated at the middle of the crista. 



Eyes single, sessil, situated halfway between the crista and the sides of the body, 

 on a level with the posterior tactile hairs. In front of the crista (Text-fig. 49) at 

 the base of the pseudocapitulum is a collar-shaped portion where the cuticle is soft 

 and finely reticulated by very minute, semispherical projections, which are arranged 

 in transverse rows at the sides. By means of this soft portion the pseudocapitulum 

 seems to be capable of being slightly retracted. 



The hairs of the body are simple, setiform and slightly curved. 



The vejitral side. All the coxte are strongly chitinous and finely punctured; 

 coxae I and II and coxae III and IV contiguous; coxa; I short triangular, not conti- 

 guous at their proximal ends but separated by a space equal to their own width. 



The legs (Text-figs 50, 51) shorter than the body; legs I and IV of equal 

 length, 0,8 mm, legs II and III also of equal length, 0,68 mm. The cuticle is thick 

 and richly provided with fine pores; the tarsi twice as high as the tibiae; hairs of 

 the legs simple, except on the ventral side of the tarsi where they are hairy on the 

 ventral side.
