The palpi (Text-fig. 48); the second joint is much wider and more curved than 
in E. medioareolatus and the third joint is shorter than the second one, whereas in 
E. medioareolatus they are of the same length; 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 maxillæ is thick and penetrated 
by numerous, fine pores. 
The maxille 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 metopica (Text-fig. 49) is finely punctured, not strongly 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. medioareolatus 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 ventral side. All the coxae are strongly chitinous and finely punctured; 
coxae I and II and coxae III and IV contiguous; coxae 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 ot 
the legs simple, except on the ventral side of the tarsi where they are hairy on the 
ventral side.
