right fore wing with one row of three cells next to the 

 triangle. 



Evidently a more fully aduU specimen. Even under the 

 most favourable illumination, abdominal segments 7 and 8 

 show no trace of pale markings. On the ventral surface of 

 segments 5-7 (but not ""on 4 and 8) are just discernible 

 orange-brown stripes similar to those seen in the holotype. 

 There are also some patches of orange-brown on the under- 

 side of segments 1 and 2. The labrum, clypeus, frons, 

 raetepimeron, pectus, and legs are blacker than in the 

 holotype.
