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 some 
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
