58 FAUNA HAWAIIENSIS 



paired subquadrate yellow spots at the anterior angle of each segment, ovipositor 

 projecting, slightly upturned and reddish-yellow. Legs yellow, the bases of the anterior 

 and the greater part of the intermediate and hind femora dark brown or blackish. 

 Wings hyaline, with three irregular dark brown bands running across from the costa 

 to the posterior margin ; the first commences immediately before the termination of 

 the 1st longitudinal vein and about its middle sends out a patch which extends beyond 

 the anterior transverse vein and joins the second band, the latter commences about 

 the middle of the wing as a very broad band, then suddenly narrows when it crosses 

 the 3rd vein, expands again on the 4th, runs over the apical half of the discal cell, 

 including the posterior transverse vein but leaving a small hyaline spot near the lower 

 exterior angle of the cell, and terminates on the posterior margin about as broad 

 as it commenced, the third band at the apex of the wing, covering the tips of the 

 2nd, 3rd, and 4th veins, and along the latter sending a projection inwards which nearly 

 meets the second band.

 and joining the former behind ; metanotum light yellow, scutellum black above, yellow 

 at the sides, halteres yellow. Abdomen black, the fore borders of the segments obscure 

 yellowish. Legs yellow with dark femora, the tips of all the tibiae slightly infuscated
