[In life this species is slate-grey with bright lemon-yellow 

 markings. It is common on exposed banks and on the leaves of 

 bushes, where its colours render it a conspicuous and striking 

 object.— F. H. G.] 



Cubaris robusta, n. sp. 



(PI. xxxiii, figs. 1-9.) 



Body (fig. i) oblong oval, convex, with lateral margins of the 

 segments slightly revolute, mesosomatic segments marked mid- 

 dorsally with a broken white line and laterally with raised longitu- 

 dinal tubercles. Cephalon (figs. > and 3) small with deep epistoma 

 and small triangular lateral lobes, median lobe absent; the dorsal 

 surface exhibits a slight median depression whilst posteriorly it is 

 sHghtly raised. Byes (figs. 2 and 3) prominent, sub-dorsal. An- 

 tennulae 3-jointed. Antennae (fig. 4) short, setaceous, flagellum 

 2-jointed, the distal joint two-and-a-half times longer than the 

 proximal one. Mandibles variable, ist maxillae (fig. 5): the 

 outer lobe terminates in four stout, incurved spines and five more 

 slender ones; numerous long hair-like setae on the outer margin. 

 2nd maxillae (fig. 6) small, terminating in a thin blade-like outer 

 lobe with numerous setae, inner lobe tooth-like with dense mass 

 of long setae. The segments of the mesosome are convex, the ist 

 strongly so ; lateral plates of anterior segments well separated and 

 slightly revolute. Maxillipedes (fig. 7) : outer palp terminates in a 

 strong spinous process with a multispinous termination, there are 

 two smaller spines on the inner border and a fourth basally ; the 

 inner palp has a single spine and a small tooth-like process on the 

 inner border. Thoracic appendages (fig. 8) elongated, with nu- 

 merous strong spines mostly on the inner border. Uropoda (fig. g) 

 somewhat robust, with triangular basal plate not extending be- 

 yond the telson ; exopodite small and articulating in a groove on 

 the inner dorsal margin, endopodite a little larger, articulating 

 with the under side of the extreme inner border, and not extend- 

 ing beyond the basal plate. Telson strongly convex, contracted 

 laterally, posterior margin almost straight. Length 8-5 mm. 

 Colour (in alcohol) horny brown. 



Habitat. — Sadyia, N.E. Assam. Under logs. 25-xi-ii. No. 

 8083/10. (5. W. Kemp.) 



Type. — In the collection of the Indian Museum. 



This interesting species finds its nearest ally in Cubaris fragilis, 

 Cllge.,^ a species I have recently described from the Andamans. 

 It differs, however, from that species in the much stouter and 

 stronger build of the first mesosomatic segment, the lateral 

 plates of which, ventrally, are much thickened, dorsally the mid- 

 dorsal portion of the segment anteriorly has a raised triangular 

 area. In the form of the telson and uropoda there are also im- 

 portant differences and the antennae are rather shorter. The
