136 ME. W. F. KIEBI" OK THE 



is more than twice as long as the part of the head already 

 described ; on the upper side are two lateral diverging carinse, so 

 that its apex is broader than its base. On the lower surface the 

 head is continued so far back that the base of the rostrum (which 

 extends as far as the middle of the abdomen) lies just in front of 

 the anterior coxae. At this point the head is tricarinate, but 

 below the eyes the lateral carinae are angulated outwards, and 

 gradually disappear towards the base of the horn. At this point, 

 too, is a long double carina in the middle, ending in a point at 

 the base of the horn. Here rises another double carina, longer 

 and narrower than the first, meeting in a point at both ends, and 

 extending just beyond the expanded upper part of the rostrum. 



Not closely allied to any known species. 



Pundaloya. 



Genus Stmplana, g. n. 



Resembles DictyopJiora, but with very different neuration. 



Head and thorax above with a wide depression on the median 

 line ; head curved up beyond the eyes, the end of the frontal 

 prominence pointed, as seen from the side ; face very long, with 

 five carinae. Tegmina rather long and narrow, vitreous, with 

 longitudinal simple nervures ; at about five-sixths of their length 

 they are crossed by transverse nervures (not extending to the 

 last space on the inner margin), and then by a straight nervure 

 quite across, so that a row of three (or, by bifurcation, four) cells 

 is formed, running from the costa nearly across the wing ; beyond 

 these, the upper nervures are forked towards the costa at and 

 before the tip. Legs simple, rather long and slender.

Long. Corp. cum tegm. 7-8 millim. 



Grreen, brighter above, and inclining to yellowish below, the 

 wide groove on the head and thorax above, and a slender line on 

 the inner margin of the tegmina, bright scarlet ; tegmina hyaline, 

 with green nervures ; wings hyaline ; claws black. 



A very delicately formed and coloured species, which does not 

 seem to be uncommon in Ceylon.
