THE TERJIESTKIAI. ISUPODA OK NATAL. 579 



Length 14 mm. 



Colour (in alcoliol) a silvery-grey with darker irregular 

 markings^ variable. 



Habitat. — Umbilo Bush, near Durban, Natal, September 

 16th, 1915. (E.Warren.) 



Type. — In the Natal Museum. 



This handsome species is easily separated from any known 

 form by the form of the antennae, in which the first three 

 joints are stoutly built, also by the form of the cephalon, first 

 maxillae, maxillipedes, uropoda, and telson. 



The colour is subject to a considerable amount of variation, 

 approaching sometimes that found in Philoscia dilectum 

 Cllge. ; in most cases, however, there is an oval light-coloured 

 marking sui'rounded by darker pigmentation, just above each 

 pleural plate, and in the mid-dorsal line a somewhat similar 

 light-coloured area on each segment of the mesosome, with a 

 darker one immediately posterior to it.

Body broadly oval, convex, surface finely granulated, 

 metasome abruptly narrower than the mesosome. Cephalon 

 (PI. XLII, figs. 21 and 22) small, convex above, frontal 

 margin distinct, lateral lobes absent, epistome concave above 

 dorsal ridge and slightly raised in the median line. Eyes 

 large, also ocelli, situated dorso-laterally. Antennula3 (fig. 

 23) short, with 1st and 2nd joints stout, 3rd joint with 

 lateral and terminal seta?. Antennas (tigs. 2-i and 25) com- 

 paratively short, slender, 1st joint larger than usual, 2nd and 

 3rd almost subeqiial, 5th the longest, setaceous; fiagellum 

 3-jointed, 1st joint the longest, 2nd and 3rd subequal, with 

 bluntly ending style. First maxilla? (fig. 26) with outer 

 lobe terminating in four stout curved spines, and five shorter 

 ones with bifid terminations ; inner lobe truncate terminally 

 with two large setose spines. The segments of the mesosome 

 are convex, terminal margin of the pleural plates truncate, 

 posterior angles on segments 1-3 rounded, on remainder 

 pointed and produced slightly backwards. Maxillipedes
