males. Moreover, even the females have not been properly investigated, as in 
many of them the shape of the epistome has not been described.

Colour chestnut-brown. 
The dorsal shield (fig. 121) covers almost the whole dorsal side, leaving 
only-a very narrow strip of soft cuticle unprotected at the sides and the pos- 
terior end. Its anterior edge is broadly rounded and from the shoulders it 
narrows gradually backwards with almost straight sides. The texture is poly- 
gonal, marked with fine raised lines, the areas being areolated. The whole 
pattern is, however, rather faint and is obliterated along the anterior margin 
and in the posterior end, where there are smooth areas. From the shoulders 
there runs an almost semicircular, darker line across 
the body. A somewhat similar line has been de- 
scribed “by VITZTHUM (1926, figs-20;"pi830)) ames 
multthamatus. 
The vertical hairs (fig. 122) are lanceolate, thin, 
with fine oblique fringe at the top. The other hairs 
are fairly stout, curved and finely hairy in the distal 
half (fig. 123) and of almost uniform size. There are 
also numerous pores scattered over the dorsal shield. 
Ventral side. The sternal. shielde(iemuzes) 
is fused with the endopodal shields to the angle be- 
tween coxe II and III; further backwards it is free. 
Its anterior margin is deeply excavated, less so the 
posterior margin. It widens considerably between 
coxe II and III, and the postero-lateral angles are 
obtuse. The sternal shield has a very distinct, straight,

posterior pair a line is running transversally towards 
the middle. In the anterior half, in the middle very faint small circular de- 
pressions are visible, otherwise the shield has no sculpture. The three pairs 
of hairs are present in their usual places. 
Metasternal shields very small, oval, with one bristle (fig. 129). 
Genital shield (fig. 129) rather small, with straight posterior margin, a 
little excavated near the postero-lateral angles. It is by a pair of deep lateral 
incisions constricted in the middle into two parts, one posterior which is al- 
most semicircular, and one transparent anterior, which is oval. Along the 
margin of the posterior shield there is a pair of narrow, bar-shaped ridges. 
The genital shield has two oblique lines converging forwards and one pair 
of hairs. 
The ventri-anal shield (fig. 130) is small, about 270 ». long and 250 u. wide, 
elongated pentagonal, with almost straight anterior margin and well rounded 
posterior end. It is sculptured by six anteriorly convex, nearly paralell, curved
