ment to me, as having visited this country before and having found 

 a great variety of insect life, I had counted upon this to 1:)C so again. 

 I had intended to push on further into the interior and I would liave 

 done so only for my becoming ill, which put an end to all my plans. 

 In the meantime and before I was taken ill I captured a few inter- 

 esting specimens in places where the ground was beginning to show 

 green, but the variety of species was lacking. 



Bartica. — Temperature in the sun, 110 to 120 degrees, in the 

 shade, 80 to 84 degrees, during rain, 70 to 72 degrees. The ground 

 is comparatively low, but a short distance back it rises into the 

 hills.

 shade, 80 to 84 degrees, during rain, 68 to 70 degrees. The altitude
