MALAYAN CICADIDAE. 89 



The opercula are long and overlapping at inner mar- 

 gins, their outer margins slightly concavely sinuate, their 

 apices convexly rounded; the rostrum reaches the poste- 

 rior coxae.

This genus is allied to Bceturia and Karenia by having 

 the anterior margins of the first dorsal segment of the 

 abdomen neither produced nor sending forward a lobe , thus 

 rendering the tympana visible. Its principal characteristic 

 is found • in the vertex of the head , which is laminately 

 produced on each side in front of the inner margin of the 

 eyes in somewhat rectangular processes. 



The body is very robust , the abdomen broad and mode- 

 rately inflated , its lateral margins distinctly keeled beneath ; 

 the opercula are short, as in the genus Pomponia; the 

 rostrum in the typical species here described about reaching 

 the posterior coxae, its second joint somewhat compressed 

 laterally and dilated and deeply grooved above; anterior 

 femora robust and spined beneath at apex. Tegmina short, 

 broad , about as long as the body , apical areas eight in 

 number, first longer than the second, basal ulnar area 

 very slightly ampliated anteriorly.

Body above and beneath dark chocolate-brown ; head 

 with a longitudinal fascia to front, the margins and a 

 transverse fascia to the ampliations in front of eyes , and a 

 transverse spot at anterior margin of vertex, behind which 

 are two outwardly curved lineate spots ochraceous, eyes 

 luteous; pronotum with a central black hour-glassed sha- 

 ped fascia somewhat margined and streaked with ochi'a- 

 ceous , the posterior margin also ochraceous ; mesonotum
