apicem subrotundate, pilosiuscula, ante apicem plica trans- 
versa instructe ; venis numerosis hyalinis dense sed irregu- 
lariter cribrosis, cellulis apicalibus numerosis : posticze parve, 
vix angustate ; venis simplicibus, furcis apicalibus duabus, 
vena transversa una. Pedes vix pilosi; tibiae plane, utrin- 
que sulcate ; tarsi 2-articulati, posteriorum articulo 1° valde 
elongato. 
A very singular genus, on account of the deep transverse fold 
or bend in the anterior wings just before the apex. These wings 
are densely reticulated with numerous little hyaline veinlets dividing 
the membrane into small cell-like spaces, which are more abun- 
dant in some parts than in others, and are altogether absent in the 
apical portion beyond the fold; some of these veinlets branch off 
without meeting others, and are then abruptly terminated in the 
membrane.

A beautiful insect; the large blue blotches on the anterior wings 
are visible only in certain lights.
