 the specimens were of a greenish hue, variably marked 

 with spots of other colours, chiefly resembling those on 

 the leaves themselves. Green grasshoppers and locusts 

 were very abundant, together with the common Mantis, 

 and various spiders ; while occasionally specimens of 

 Hemiptera were met with, one, a species of Membracis, 

 being chiefly remarkable owing to its large and pointed 

 crested thorax, the anterior wings being of a deep 

 green, striped with obscure red lines, and somewhat

 overhead, and quite out of reach, were to be seen 

 magnificent specimens of the flattened silver spider 

 (Argiope argentata), and the thick-bodied nephila 

 (Nephila clavipes), with immense webs spread out over 

 the curtain-like masses of leaves. 



Late on Tuesday evening we passed through consider-

 on the East bank, rushing and roaring down the slope. 

 Immediately beyond, a large island breaks up the 

 channel, the passage on the left bank curving out into a 

 deep bend, the whole distance being almost a continuous 

 rapid with a very strong rush of water ; while that on 

 the right, shorter and more like a catara6l, leads across 

 direftly to the upper side of the island, where a long

 and with a total height at least of about 15 feet, 

 opens to the view. The channel was rendered very 

 beautiful owing to the masses of the flowering water- 

 weeds (Lacis, etc,,) which are here particularly abund- 

 ant and of large size — a point of beauty quite unappre- 

 ciated by the hands, who found the bed extremely
