d\ Supra-antennal carina sharply angled where it crosses frontal 



suture, from this point passing straight cephalad for a short 



distance; tegmina thickly coriaceous, opaque, the puncturing 



very coarse. 



«\ Transverse wrinkles numerous on face above, and fine and 



regular; supra-antennal area with about ten small wrinkles 



between its lower point and the ocellus K. muirii sp. nov. 



e\ Transverse wrinkles few on face above, and coarse and irreg- 

 ular; supra-antennal area with about five large wrinkles 

 between its lower point and the ocellus. 



K. olivascens sp. nov. 

 e\ Vertex with a series of about four submarginal carinse, the pos- 

 terior incomplete, together occupying about one-half of vertex, 

 the posterior portion of disk rugose; otherwise like the species. 

 K. olivascens var. singaporensis var. nov. 

 «-. Lower margin of transversely wrinkled ocellar area with a strong, 

 uniform, transverse carina, without or with very few weak wrinkles 

 below it, and with the wrinkles above it much weaker ; supra-antennal 

 area smoothly concave; frons below ocellar area strongly deeply 

 depressed, and with three large smooth foveate arese above; punctura- 

 tion of tegmina minute, weak, sparse, most evident along veins; vertex 

 without a submarginal carina near anterior marginal carina. 

 b\ Disk of pronotum very strongly arched; color pale virescent; wings 



milky subhyaline K. magna sp. nov. 



fc\ Disk of pronotum very weakly arched; tegmina carmine basally; wings 

 deep smoky K. colorata sp. nov. 



Krisna minima sp. nov. ul Plate I, fig. 2; Plate II, fig. 8; Plate 

 III, figs. 3 and 6. 



Length, male, 8.5 millimeters. Pale stramineous dry, but 

 doubtless virescent in life. No dark spot at apex of clavus and 

 no dark markings on head. Vertex anteriorly margined with 

 carmine. Similar to K. strigicoUis but very much smaller.

Krisna strigicoUis Spinola. Plate I, figs. 1, 5, 6, and 8 ; Plate II, 

 figs. 7 and 9 ; Plate III, fig. 10 ; Plate IV, figs. 6 and 12. 

 Length, female, 12 millimeters; male, 10 millimeters. Pale 

 stramineous dry, but vividly virescent in life, with vertex an- 

 teriorly bordered more or less broadly with carmine, and with 

 a submarginal black stripe, which is often obsolete on middle of 

 sides, leaving two black dots near margins of eyes and two near 

 median line, but these also may be obsolete. Wings usually 

 milky subhyaline. Last ventral segment of female behind trun- 

 cate to more or less broadly angularly emarginate.
