11. Eurypteryx Mirabilis sp. nov. Taf. VI, Fig. o. 

 Tliis extraordinary iiisect is tlu^ second discovered of the 

 genus Euryi)teryx. E. MoUuccae Feld., the other species, is 

 Yery imperfectly known as the only kiiown specimen, the 

 type, is in very bad coiidition, in fact almost unrecognisable, 

 and I believe the flgure in the Novara Reise to be i)ure 

 fantasy. I thought at one time the specimens I am des- 

 cribing below were only line examples of Moluccae Feld, but 

 the two conspicuous yellow patclies near the apex of the 

 Ibrewings are wanting. Forewings dark chocolate brown with 

 a double Stigma in the cell of l)rilliant silver. about one tifth 

 froni the base and behind the cell is a large wedge shai)ed 

 blotch of yellowish olive brown. traversed from the costa to 

 the inner margin by life light and dark transverse zigzag 

 lines. At the apex of the cell, joiiied to the costa, and reaching 

 from the cell two thirds of the way to the apex of the wing: 

 is an oblong and large brownish grey patch, in front of which 

 is a reddish dot. as also at the angle of the inner margin. 

 Hindwings l)lack. costal margin pale Inift", anal angle mucli 

 produced and brownish red; on the costa there is a large 

 hooked projection. Body black brown variegated with a few 

 red hairs. Female similar to male but much paler in colour. 

 Expanse S 0^/4 inches = 95 millim. 9 4 inches = 102 millim. 

 Habitat: S Kina Balu. Borneo. ? Sumatra.
