406 R. I. POCOCK 
band; stoma-saddles testaceous, stomatal area dark-coloured ; 
legs of a very pale olivaceous tint, femora furnished beneath 
with two dark patches, patella marked with three dark green 
annuli, tibia with two dark green annuli, tarso-metatarsus with 
one proximal band of this same colour; head marbled with dark 
green, antennae ochraceous, the femur of the maxillipede with 
one external patch of dark green. 
Head; region of labrum hairy, frontal region spicular and 
marked with the three normal sulci, the oblique curved ones 
which run inwards and forwards from the inner angle of the 
eye and the median one which extends backwards to the occi- 
pital region; the inter-ocular area flat, defined behind by a 
crescentic depression which, concave forwards, runs from eye 
to eye; the posterior occipital region marked by a median nearly 
circular depression, which is scarcely noticeably continuous with 
the transverse depression; this region of the head sparsely 
spicular. 
Tergites marginally serrate, irregularly but conspicuously 
spicular, those in the anterior half of the body marked with 
shallow depressions defining two rounded elevations. Stoma- 
saddles much wider than long, each half rounded and but 
little elevated; stomatal area triangular, widely open behind; 
stomata small, elongate and slit-like, not projecting so far 
posteriorly as the margins of the saddles; posterior tergite 
very wide behind, quadrate, with lightly convex hinder 
border. 3 
Sternites hairy, medianly sulcate. 
Legs hairy; femora sub-serially spinous, patella and tibia ca- 
rinate and serrate. 
Length 19 mm. 
A single specimen from Palon, collected by Sig. L. Fea. 
In colour this species appears somewhat to resemble Se. ma- 
culata of Newport from Australia; it differs from it, however, : 
in its wide posterior tergite. By this character, as well as by 
being more strongly coloured and having the occipital region 
of the head differently depressed, it may be separated from
