6. Tarsus of fourth leg comparatively stout, especially in the female, 
with one or two segments, but in the latter case the two segments are subequal 
in length and not movably articulated with each other. Patella and tibia of 
palp without true spines below, the tibia being thickly studded all round with 
brownish black truncated cylinder bristles. Chelicerae of male without spines 
above, but with long slender curved bristles. Flagellum of male a large flat 
rigid membrane rotatable at its narrow end, bearing on its mesial surface a 
delicate capsule with long slit-like opening, and terminating at its broader 
end in slight exfoliations, two of which are more or less like short horns: 
second and third sternites with numerous fleshy hairs. Species of small size 
and with strongly contrasting colours. Hemiblossia Kraepelin. 
7. Similar to Hemiblossia, but patella and tibia of palp in both sexes 
with stout spines below in a double row. Tarsus of fourth leg comprising only 
one segment, which is comparatively slender (5-6 times as long as deep). 
Flagellum membranous, forming an inflated capsule open along its mesial 
side. Second and third sternites of male each bearing two clusters of several 
modified fleshy hair structures. Gluviopsis Kraepelin. 
b. Tarsus of first leg with a pair of small or minute tarsal claws. 
Flagellum of male when present rotatable (or fixed apparently in 
some species). S. /. Karschiinae. 
Subfamily KARSCHIINAE. 
8. Tarsi of legs II— IV with two freely movable segments, the basal one 
five or six times as long as the distal segment, which has very long, strongly 
diverging, subungual appendages. Tibiae of legs II and III spined dorsally, 
but leg IV without spines. Tibia of palp more or less cylindrical, not attenuated 
distally, and without true spines or scopula inferiorly, the patella with five 
very long bristles on each side inferiorly. Upper surfaces of chelicerae and 
body without strong spines. Anterior margin of head -plate rounded. Ocular 
tubercle armed with a number of fine bristles especially in front. Basal enlarge- 
ment of flagellum small and not very sharply differentiated from the shaft, 
attached by a fairly large rotating joint (sometimes fixed?) to the inner 
surface of the jaw, and produced directly upwards into the shaft: basally, it 
is protected and more or less concealed on the mesial side by a fan -like row of 
feather bristles or by several spines. Upper lobe of rostrum evenly pointed 
at the apex, the lower margin being not horizontal but inclined upwards. Coxa 
of palp with a short maxillary process. Ceroma Karsch. 
9. Similar thereto, but adult male without a flagellum. Upper lobe Of 
rostrum unevenly pointed, the lower margin being horizontal and very slightly 
concave, and the upper margin curving strongly downwards. 
Toreus Purcell. 
10. All the legs with a single tarsal segment and small pul villus. The two 
halves of the genital sternite of the female not united mesially. Adult male 
without a flagellum and no fleshy hairs on the second abdominal sternite. 
Patella of palp with strong spines inferiorly in the male: tibia of palp with 
numerous truncated cylinder bristles inferiorly especially in the male. Ocular 
tubercle with a pair of spines anteriorly. Tibia of leg IV with slender spines 
inferiorly in the male: of legs II and III with four or five stout dorsal spines 
also. Lipophaga Purcell.
