xv, 2 Baker: The Genus Krisna (J as sides ) 211 
of genera formerly classified elsewhere must be removed to it. In 
fact, some of the species described in Selenocephalus do not even 
belong in the Selenocephalaria. The tribe Tartessusaria includes 
Tartessus Stal, (?) Borduria Dist., Macroceps Sign., Putoniessa 
Kirk., Sarpestus Spang., and Thymbris Kirk. Some of these 
may be synonymous with Tartessus. Drabescus Stal should be 
removed to the Selenocephalaria. 
The present paper is concerned especially with two genera of 
the Stegelytraria, the genera of which may be separated as 
follows : 
Tribe STEGELYTRARIA 
Key to the genera. 
a 1 . Tegmina without distinct appendix; length of tegmina beyond clavus 
about one-third length of clavus. 
b 1 . Vertex anteriorly horizontally rounded; anterior pronotal margin 
arched, posterior margin slightly emarginate; tegmina with two 
subapical cells . Stegelytra M. and R. 
b 2 . Vertex anteriorly subangulate; pronotum anteriorly subtruncate be- 
tween eyes, posteriorly subtruncate between scutellar angles; teg- 
mina with four subapical cells Iberia Kirk. 
a 2 . Tegmina with a well-developed appendix; length of tegmina beyond 
claws more than half length of clavus. 
b 1 . Venose portion of tegmina beyond clavus strongly narrowed, the apical 
cells long and narrow, anterior margin of pronotum broadly rounded 
between eyes; frons medially never carinate and always much 
broader than width of eye in facial view. 
c\ Tegmina apically with numerous supernumerary veins (Plate I, 
figs. 1, 3, and 5) Krisna Kirk. 
c 2 . Tegmina apically normally without supernumerary'- cross veins 
(Plate V, fig. 1) Gessius Dist. 
b\ Venose portion of tegmina beyond clavus not narrowed, the apical 
cells broad in proportion to length; anterior margin of pronotum 
narrowly rounded between eyes; frons medially carinate; distance 
between eyes subequal to width of eye in facial view. 
Coelidioides Sign. 
Genus KRISNA Kirkaldy 
A common evening visitor to one’s table lamp, almost any- 
where in the Malaisian countries, is a vividly virescent leaf- 
hopper of the genus Krisna, a half inch, more or less, in length, 
and with the transverse fore margin of the vertex black or a 
bright reddish color. This is likely to be Kristia strigicollis, but 
other species frequently occur. These insects were known for 
many years under the generic name Siva Spinola , 1 but that name 
being preoccupied, Kirkaldy 2 renamed the genus Kristia.
