forking again toward apex; sutural vein (second cubital of Tillyard) 

 forking no great distance beyond the union of the anals; second anal 

 (Tillyard) running parallel with margin and close to it, the first anal 

 having a double curve and joining it not much before middle of 

 tegmen; lower margin strongly angulate subbasally. 

 Type. — Thaumastocladius simplex, new species.

Represented by a tegmen lacking part of base and apex, the length 

 as preserved 8 mm.; probable total length, 9 mm.; width in middle, 

 3.3 mm.; veins fuscous. Mediocubital fork about 1.2 mm. anterior 

 to fork of sutural, the latter about 5 mm. from base of tegmen; junc- 

 tion of anals about 4 mm. from base; costal area about 1 mm. wide.

This is evidently a Fulgorid, but the combination of a broad costal 

 area with simplified discal veins and a definitely forked sutural 

 excludes it from any genus known to us. There is, however, a close 

 general resemblance to the oriental genera Gaja Distant and Bochara 

 Distant. In Fulgora maculata Olivier, from Ceylon, the sutural 

 vein may fork a short distance before the apex, or may be simple.
