SCELIMENA.

Central and lateral carina? well marked, the latter slightly incurved 

 in front, and uot extending to the front lobe of the pronotum. 

 Prouotum with two elevations on each side 

 before the middle, and generally tipped with 

 red. Tegmina grey, twice as long as broad, 

 and obtusely pointed towards the extremity. 

 Wings slightly iridescent hyaline, as long as 

 or somewhat longer than the prothorax, and 

 crenulated on the hind margins ; costa brown. 

 Pront and middle femora with two or three 

 small teeth beneath ; hind femora with several 

 small pale teeth beneath ; hind tibiae and first 

 tarsal joint with narrower and less rounded 

 lamellae than in S. liarpago. 



2 • Anal appendages black or red, nearly as 

 in S. harjiago ; ^ appendages much shorter. 



Lem/th, to end of pronotum, 21-24 mm. ; 

 to end of abdomen, 11-14 mm. ; breadth of 

 pronotum from spine to spine, 8-10 mm.; 

 length of tegmen, 2 mm. ; of hind femur, 

 9 mm. ; expanse of wings, 43 mm. ; breadth, 

 13 mm. 



Madras: Trivandrum; Ceylon: Peradeniya, Damballa, Mas- 

 keliya, Pundaluoya. 



Type location unknown ; that of S. nodosa in the British 

 Museum. 



" One female, Dambella, October, ' from margin of tank ' ; two 

 females, Maskeliya, November and February ; five females and 

 four males, Pundaluoya, March, were taken from rocks in 

 mountain streams ; when disturbed, either takes wing or dives 

 under water and remains submerged for some time; larva in similar 

 situations. Two more males and several nymphs Mere taken in 

 June from the same locality." (Ilancocl-.) 



The white tip to the tegmina noted by Walker in his description 

 of S. nodosa only occurs on one side, and is clearly accidental. 



This appears to be the species alluded to as Scellmena liarpago 

 by E. E. Green (Entom. M. Mag. xxxviii, 1902, p. 215).
