Hab. Banks of the Maranon, near Balsas, Peru (on branches of a 
species of Jatropha); W. Lobb. 
This fine species is of a delicate cream-white, striped longitudinally 
by distinct ribands of light brown and dark purple chestnut, without 
any of intermediate tint. Immediately behind the lip there is more of 
the dark purple chestnut, approaching to black, and the interior of the 
aperture is coloured with the same, having a somewhat metallic hue. 
I have the pleasure to name it in honour of Mr. William Lobb, bo- 
tanical collector of Messrs. Veitch and Son, the eminent nurserymen 
of Exeter, to whose zeal in the pursuit of natural history the disco- 
very of these interesting species bears honourable testimony.
