Hah. Java. 



A very distinct and well-marked form, differing from the only 

 two other described species of the genus in the shape of the 

 thorax and notably in the colour of the body and wings. The 

 type and only specimen is evidently an insect collected many 

 years ago, though still in fair preservation.
