parts: festoons rectangular, twice as broad as long, nos. 1, 2, and 3 only, 
on each side, divided by the marginal groove from rest of body. 
Scutum, length 1'08—1'37 mm., breadth l - 05—131 mm.; broadly 
elliptical with flattened postero-lateral margins; dark reddish-brown 
with darker irregular markings; deeply emarginate anteriorly for 
reception of basis capituli; surface polished, traversed by minute 
irregular radiating furrows; punctations irregularly scattered, few in 
number: cervical grooves deep anteriorly, shallow and wider posteriorly, 
almost parallel throughout their length. Venter:—spiracles nearly 
circular, external margin flattened, macula large and slightly excentric: 
genital grooves divergent, do not quite reach festoons posteriorly: genital 
orifice opposite interspace between Coxae II and III: anus nearly 
circular; valves' punctate and bearing 5 minute hairs on each : anal 
groove well-marked, bifurcated at its anterior extremity in the form of 
a Y, the forks of which encircle the anus on either side and terminate 
in the genital grooves. 
Capitulum (see text figs. 3—9, p. 169 et seq.): length, 770—880 p 
(from line joining tips of palps to line joining extreme postero-lateral 
angles of basis capituli): basis capituli rectangular, cornua obsolete; 
porose areas large, well separated, rather wider than long ; ridge on 
ventral surface semicircular in contour: palps valvate, sub-conical, 
truncated; article 1 small, almost entirely concealed within the basis 
capituli, article 2 contracted proximally, much widened out distally 
with a prominent ridge running round its ventral, lateral and dorsal 
surfaces and forming the external angle of the palp; infra-internal 
margin furnished with a continuous fringe of feather-like hairs, usually 
thirteen in number but subject to some variation; three similar hairs on 
corresponding margin of third article, the ventral surface of which is 
produced as a large pointed backwardly directed protuberance; article 
4 small and stumpy, with a tuft of stiff hairs on its free extremity, 
Neumann (1897, p. 328) gives the number of these hairs on the fourth 
segment of the palp as six; we have found eight to ten such 
hairs, but the number does not appear to be by any means constant): 
chelicerae: internal article with large base and prolonged as a single 
cutting-lancet with an outwardly turned point; dorsal process crescentic 
with the points folded towards each other; external article a flattened 
plate with four (sometimes five) outwardly directed cusps, the first of which 
is the smallest, the others gradually increasing in size to the largest 
1 Neumann (1897, p. 328) says that the anal valves are punctate, but without hairs : 
we have invariably found five minute hairs on each valve in addition to punctations.
