xv - 2 Baker: The Genus Krisna (Jassidte) 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. 



a 1 . 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 areae, with coarse uniform wrinkles; 

 frons scarcely depressed „ 6. 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.
