xv, 2 Baker: The Genus Krisna ( Jassidse ) 217 
occur in Gessius. Here are included some common insects of 
the Malay Peninsula, Borneo, and the Philippines, which I have 
no doubt were frequently collected previously; and specimens will 
probably be found in collections placed with Krisna, especially 
Krisna strigicollis. 
Among these insects there is a most confusing variation of 
color shades from bright rufous to stramineous (virescent). 
All specimens in a large series of several species and varieties 
possess an unmarked vertex with at most a crimsoned anterior 
margin, a dot at the apex of the clavus, the wings more or less 
smoky, the dorsum more or less crimsoned, and all below stramin- 
eous. The three or four inner apical cells of the tegmina are 
subhyaline and impunctate, in strong contrast to the remainder 
of the tegminal surface. 
General sculpturing very similar to that of Krisna and simi- 
larly distributed. 
In all of my material I have no specimens with “the claval 
area fuscescent, this color longitudinally continued to apex of 
tegmina” as described by Distant for the type of the genus, G. 
verticalis, from Burma. 11 Is it possible that this fuscescent area 
is due to the color of the smoky wings beneath? 
Key to the Malayan species. 
at Transverse wrinkles of ocellar area confined to a space twice the width 
of an ocellus, the frons suddenly depressed below this, and irregularly 
rugose; supra-antennal area smooth G. malayensis sp. nov. 
a*. Entire upper part of face, down to lower margin of supra-antennal 
ledges, including supra-antennal areas, with coarse uniform wrinkles; 
frons scarcely depressed G. pallidus sp. nov. 
Gessius malayensis sp. nov. Plate V, figs. 1, 2, 5, 7, 10, and 12. 
Length, female, 10.5 millimeters; male, 9 millimeters. Above 
clear shining pale rufous (variable) , below stramineous. The 
form of the last ventral segment in the female is distinctive, it 
being deeply, broadly, angularly emarginated, the sides of the 
emargination sharply notched. Wings very dark veined. 
A common species in the Malay Peninsula and Borneo. 
A closely similar form is found in Butuan, Mindanao, and in 
Basilan, which differs only in that the lateral notches in the 
emargination of the female segment are uniformly shallow and 
reduced to a strong sinuation. This form may be known as 
var. mindanaensis var. nov.
