66. Topana rubiginosa sp. nov. 



About the size of ciucticornis Stal, but somewhat more robust. 

 Hind margin of elytra for about two-thirds of their length straight. 

 Fastigium of the vertex open behind, but scarcely tuberculate. Pro- 

 notum with the disc flat and entirely margined with a raised carina, 

 which on the sides is bisinuate, so as to leave a rather prominent 

 outwardly directed tooth. Legs much as in cincticornis, but with only 

 two large compressed spines, instead of four to five smaller slender 

 ones on the front and intermediate femora. 



Head rust-red, the fastigium of front and of vertex ivory-white, 

 basal antennal joints testaceous, beyond at rather distant intervals 

 widely banded with fuscous, as in cincticornis. Pronotum on the 

 lateral lobes, pleura, and abdomen ferruginous; the disc dirty yellow, 

 very narrowly bordered in front and at sides with purple, becoming 

 black on hind margin inside of the bounding carina, the latter old- 

 ivory-white. Tegmina yellowish green, with the stridulating field 

 and dorsal margin, the base of costal field, and a large patch 

 on middle of hind border, solid ferruginous; the remainder of costal 

 and ulnar borders irregularly blotched with patches of the same 

 color. Basal third of hind femora and apex of all the femora and bases 

 of the tibicC dark ferruginous. 



Length of body, cf , n mm., of pronotum, 3 mm., of tegmina, 21 

 mm., width of tegmina, 7.15 mm., length of hind femora, 12.25 mm.
