teriorly narrowly margined with black, this margined behind 

 with carmine ; face above with a submarginal narrow black line, 

 this again margined below with carmine. Tegmina thickly co- 

 riaceous, very strongly punctured, the appendix smoky, and somo 

 of the inner apical cells stained with smoky. Hind margin of 

 last ventral segment incurved. 



This very fine species is not uncommon in Singapore and 

 Penang; and I have specimens from Sandakan, British North 

 Borneo. 



A remarkable variety of this species, from Singapore, has 

 the vertex quite differently sculptured, and it is somewhat paler 

 in color, but otherwise similar to the typical form. I call it 

 var. singaporensis var. nov. 



Krisna magna sp. nov. Plate II, figs. 3 and 5 ; Plate III, figs. 1, 

 4, 12, and 14 ; Plate IV, fig. 3. 



Length, female, 14 millimeters; male, 13 millimeters. Dis- 

 tinct from all other oriental species in the genus by its very 

 robust form, the body being very thick, and very strongly arched 

 across base of pronotum. Very pale virescent above, stramin- 

 eous below. Vertex anteriorly with two minute black dots next 

 to eyes. No spot at apex of clavus. Wings milky subhyaline. 

 Sexes strikingly different in form of head. 



Specimens come from Penang Island and from Sandakan, 

 British North Borneo, though apparently the species is not com- 

 mon. This is the largest known oriental species of the genus. 



Krisna colorata sp. nov. Plate II, fig. 1; Plate III, fig. 7; Plate 

 IV, fig. 1. 



Length, female, 13 millimeters. Anterior portion of pronotum, 

 vertex, and all below stramineous; pronotum posteriorly and 

 scutellum pale rufous. Tegmina smoky subhyaline, veins and 

 basal two-thirds washed with carmine. Wings deep smoky. 

 Vertex with a marginal line of carmine, and two large black 

 dots near eye margins. Last ventral segment with the margin 

 broadly scarious. 



British North Borneo, Sandakan (Baker). 



Genus GESSIUS Distant 



There is no question of the very close relationship of this 

 genus to Krisna; the venation of the tegmina furnishes the only 

 real means of separating them and even this shows close rela- 

 tionship, in as much as occasional abnormal supernumerary veins
