206 PERCY SLADEN TRUST EXPEDITION, 
and inconspicuous, scarcely prominent; the median pair separate by about their own 
width, broadly conical, their outer margins smooth or inconspicuously excised ; second 
pair duplex, the inner lobule largest, the outer lobule with a large oval pore on its 
dorsal face. Circumgenital glands in five groups; median 4 to 7; upper laterals 6 to 7; 
lower laterals 4. Length of body 0°60 to 0°65 mm. 
Near Vytilaspis pomorum, but differing in colour of puparium and in the presence 
of ear-like lobes at base of head.

Mytilaspis ocellata, sp. nov. 
Female puparium elongate, narrow, approximately straight, moderately convex above, 
with or without a narrow flattened border. Colour pale fulvous; larval pellicle 
ochreous yellow. Surface usually with fine transverse corrugations, occasionally 
smooth. Length 2 to 2°50 mm.; breadth averaging 0°50 mm. 
Male puparium similar, but much smaller. Length 1:25 mm,

Mytilaspis ocellata. 
Cephalic extremity, showing rudimentary eyes and antenne. 
Adult 2 of normal form: broadest across the median abdominal segments. There 
are well-defined eye-spots on the lateral margins of the cephalic segment, on a level 
with the rudimentary antennxe. These spots take the fuchsin stain somewhat deeply, 
and are further defined by a surrounding area of fine concentric lines (see fig. 47). 
Anterior spiracles with a small group of parastigmatic glands. Lobes of pygidium 
arranged as in citricola; lateral lobes very small, each lobule less than half the width of 
one of the median lobes. Circumgenital glands in five groups, median group with from 
2 to 4 orifices ; anterior laterals 9 or 10; posterior laterals 7 or 8. Length 0°75 mm.; 
greatest breadth 0°35 mm. 
Habitat. On fronds of Davailia sp., Seychelles: ‘in mountain forest, 3000 feet.”

This species bears a very close resemblance, in form and colour of puparium, to
