xv. 2 Baker: The Genus Krisna (Jassidae) 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\ Vertex anteriorly horizontally rounded; anterior pronotal margin 

 arched, posterior margin slightly emarginate; tegmina with two 



subapical cells Stegelytra M. and R. 



b*. Vertex anteriorly subangulate; pronotum anteriorly subtruncate be- 

 tween eyes, posteriorly subtruncate between scutellar angles; teg- 

 mina with four subapical cells Iberia Kirk. 



a'. Tegmina with a well-developed appendix; length of tegmina beyond 



clavus more than half length of clavus. 



b l . 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) Zrisna 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 Kri&na, 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 Krisiw, 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 ~ renamed the genus Krisna.
