the triangle, the second of the triangle longly and regu- 

 larly trifiircate. 



$ . Wings hyaline, anterior margin slightly tinged with 

 greenish-yellow ; tlte apex (from about the middle of the 

 pterostigma) brown, slightly areolated with paler (in the 

 posterior Avings this brown portion forms only a rather 

 large spot under the pterostigma). 



Nasus, labrum, cheeks and orbits livid (possibly bluish 

 in life); head otherwise black, with four bluish-grey spots 

 between the eyes, two anteriorly and two posteriorly. 

 Prothorax with two large brown spots. Thorax yellowish 

 on the sides, varied with black (or, more properly, black 

 with yellow lines), above black, the ante-humeral and 

 humeral lines greenish, enclosing a black oval between 

 them. Legs black ; the base of the femora brown in- 

 teriorly. Abdomen black; first segment broadly yellow 

 on the sides ; second ^\\\h. rather broad lateral lines ; third 

 with a yellow spot anteriorly followed by a very narrow 

 lateral line ; fourth with a similar spot, but with no line. 

 Appendages distinctly denticulate externally. 



2 . Wings entirely hyaline, very slightly tinged with 

 yellowish ; the anterior margin more distinctly greenish- 

 yellow. Front nearly entirely piceons ; the cheeks and 

 orbits livid ; prothorax Avith a brown spot on either side, 

 and margined with brown. Thorax more distinctly 

 yellowish, Avith black lines, the yellow predominating. 

 Base of abdomen as in the $ (mutilated after the third 

 segment).

The $ is very distinct from all described species in
