SPOLIA ZEYLANICA. 
But the principal entomological interest was centred in the ancient 
reservoir, which was still watertight and contained a fair-sized poo 
surrounded by mud and sand. Hundreds of small red and black 
Staphylinid beetles (of a species that appears to be common all over 
the Island) were running over the mud. I captured two species of 
Tettrigid grasshoppers (Scelimena logani and Euparatettix personatus). 
The former is truly aquatic, having the hind legs flattened and 
flanged for swimming. Both the larvse and the adult insects rest 
on the margin and dive into the water when disturbed. Another 
abundant insect on the water’s edge was a small shining black cricket 
(Tridactyla nigrceneus). Mr. R. C. Punnett, who visited the place 
a few days later, brought back specimens of a mole-cricket that 
were found in the mud, actually under water. The time at my 
disposal was too short to permit of an exhaustive investigation of the 
fauna of this pool. The insects captured were, none of them, rare 
or peculiar ; but it was interesting to find this small isolated pool on 
the summit of a barren rock so fully populated.
