All the segments are marked by grooves, while the muscular spots, 
of which those in the median rows are placed near to each other just 
as the hindmost ones in Eu. segmentatus, are comparatively indistinct. 
The head is more hairy, ånd the hairs, chiefly those in front, much 
longer. The first pair of eyes are round, the second oblong. The 
labial appendages bear three median slender hairs that are directed 
outwards. 
Pseudocapitulum. As I had only one specimen at my disposal, 
I have not been able to examine and understand the pseudocapitulum 
in the details, which I regret, because there seems to be some 
important structural differences, perhaps of generic value. The free 
part of the labrum is very well developed, directed upwards, toothed, 
and as long as one third of the pseudocapitulum. The hindmost 
largest fifth tooth of the maxillary lobe bears a secondary basal 
tooth. I have not seen any maæillary plate, so that it must either 
be missing or shaped quite differently. — There is a well developed 
maæillary spine. The lateral lobes on each side of the mouth of 
Eu. segmentatus are comparatively small (only "/20 of the length of 
the pseudocapitulum) but in this species they are large and very 
conspicuous. (/10 as long ås the pseudocapitulum). Their lateral 
parts seem to be directed upwards to coalesce with the labrum, in 
this way forming a very spacious mouth: their median parts are 
divided by an incision inwardly into two rounded lobes provided 
with small teeth and have outwardly a long process, the pointed 
tip of which is directed inwards. This structure of the lateral lobes 
perhaps corresponds with the great development of the free part 
of the labrum. 
Antennae.. The antennae are 'scarcely different from those of 
Eu. segmentatus. ' 
Legs. The palps, the first, and the fourth pair of legs are 
missing. The second and the third pair of legs are slender and much 
longer than the body. There is no sharp distinction between the fan 
hairs and the pointed hairs, as set forth pag. 143; the pointed hairs 
of the distal joints are more similar to those of Eu. segmentatus.
