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 

 strigicoUis 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. sinuatns 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. suffnsus var. nov. 

 (Plate V, figs. 6, 8, and 11).
