UFE-HISTORIKS OF SAWFLIKS. 275 



the opening left by my carelessness. The only safety now 

 lay in a determined lesohuion : 1 suddenly lore open llio 

 curtain, and threw my pillows so that 1 could jump upon 

 them and reach the door of the room without the danger of 

 stepping with my bare feet on the wasps, which probably 

 covered the floor of the room; and so I got out of it. I then 

 called to my servants to bring a lighted candle. As soon as 

 they saw the aniuials they declared that they did not sting, 

 and handled them without fear. Thus reassured I went back 

 to my room, and saw that it was filled with insects, which 

 appeared to have come up as full-grown termites from a hole 

 between the stones of the floor. It is clear]}' the habit of 

 termites to live in the ground in their imperfect condition, 

 and, when perfect, the winged specimens fly away. They 

 thought little of the fitness of time and place when they 

 ruthlessly disturbed my rest. It was nearly an hour and a 

 half before they had all flown out to a light set outside the 

 room to attract them. About a year afterwards the same 

 thing happened in the same room. I sent the insect to the 

 Netherlands — to the Leyden Museum ; and it has been 

 determined by Ritsema to be Dorylus Kiugii, Hagen.
