Gessius pallidus sp. nov. Plate V, figs. 3, 4, 9, and 13. 
Length, female, 10 millimeters; male, 8.5 millimeters. Above 
stramineous (in life) to pale virescent; veins of wings pale. 
The truncate last ventral segment of female is distinctive for 
the typical form of this species. It is the analogue of Krisna 
strigicollis but smaller and slenderer. 
Singapore {Baker) , frequent. 
A form very closely similar to this in every way, except that 
the hind margin of the last ventral segment of the female is 
shallowly sinuate, occurs commonly at Sandakan, British North 
Borneo. I name this var. sinuatus var. nov. 
Another variety, collected at Telok Ayer, Western Borneo, by 
Mr. F. Muir, is pale rufous above, and has the hind margin ®f 
the last ventral segment of the female distinctly incurved, and 
this may be known as var. incurvatus var. nov. 
In my Singapore material I have one male specimen, only 8.5 
millimeters long, which I cannot separate structurally from the 
typical form, but which is very dark sordid rufous above, with 
apical third of tegmina pale. I name this var. suffusus var. nov. 
(Plate V, figs. 6, 8, and 11).
