 the road, and to distant parts of the compound." 



The noise made by tlic jaws of these creatures can bo often heard during the 

 stillness of the night, in one's tent when encamped in the forest, and till its origin 

 is known is rather puzzling. It is produced apparently by numbers of these 

 creatures simultaneously gnawing or tearing with their mandibles, and ceases if 

 the traveller gets a light to ascertain what can be making this noise in the ground 

 within his very tent, but recommences as soon as his head is again laid on the 

 pillow. The best protection for timber against the ravages of white ants is using 

 seasoned wood, charring its surface and pouring round it coal tar or gas refuse, or 

 watering the ground with a saturated solution of sulphate of copper. It would be 

 worth while, in the case of public buildings, importing gas refuse for this pui-pose 

 from Europe, when not procurable on the spot.

The 'May fly' is a representative of this family. These insects lie for two or 

 three years in a larval condition, and the perfect insect then issues in countless 

 numbers, and always in the evening. The perfect insect takes no food, and Uvea 

 only a day or two.

"Wings sub-equal, reticulate. Jaws strong. The eyes very large and complex. 

 The larvEE and pupa; are aqiuitic, and the insects are in all theu- stages highly 

 prodatoiy and voracious, and a terror to the insect world.

Speaking of the Dragon-fly, Dr. Mason says, " This is one of the few insects 

 which the Karens recognize in its larval state, and they often point out the larva 

 in the water, which bears a distant resemblance to the perfect insect, but the body 

 is shorter and thicker, and their wings arc only rudimentary."
