satisfied that one cannot restore Thorell’s genus Dolopaus for 
the Eastern Asiatic forms, as I had at first hoped. Thorell 
himself regards Dolopeus as a synonym of Thalassius. 
Genus THALASSIUS, E. Sim., 1885. 
Diagnosis.—Legs 4, 2, 1, 8, or4 (2, 1) 8. Tarsal claws 3. 
Superiors long, armed beneath with 9 long denticles, inferior 
claw with one or two minute teeth. Sternum as broad as 
long, circular, emarginate opposite cox and pointed behind. 
Labium longer than broad, more than half the length of 
maxilla. Maxille attenuate at base, enlarged at apex. 
Lower margin of fang-groove with 3 stout teeth, superior 
margin with 2. A single small tooth lies on the floor of the 
fang-groove near lower margin nearly opposite the third 
tooth. Eyes in three rows (or four if one separates those of 
the posterior row)—2, 2,4. Ocular quadrangle as broad as 
long or slightly longer than broad, broader in front, narrower 
behind. Anterior centrals larger (one fourth) than posterior 
centrals or subequal, half a diameter apart; posterior centrals 
2 diameter apart. Lateral anteriors smaller (half) than ante- 
rior centrals, 2 a diameter from the latter, rather more from 
posterior centrals, 1 diameter from posterior laterals. Eyes 
of posterior row subequal ; centrals nearer together, forming a 
slightly recurving line. Lateral posteriors 1 diameter from 
central posteriors. Clypeus equal to length of ocular quad- 
rangle, sometimes more. Femora with numerous spines. 
Patelle i., ii., iii., iv. with two lateral basal and one central 
apical spine. ‘Tibie i. and il. with 2—2—2—2 spines be- 
neath, last pair apical; 1—1 lateral spines on each side in 
apical half, 1—1 dorsal spines basal and apical. Protarsi 1. 
and ii, 2—2—-2—2 ventral and 1 central apical spine, 2—2 
lateral spines in basal half. ‘Tibia and protarsi 11. and iv. 
somewhat similarly but more irregularly spinulate. 
No true scopula beneath protarsi or tarsi, but a band of 
sete: and fine short hairs mingled. 
A single palpal claw with 3-4 short blunt denticles.
