shape, the posterior edge nearly at right angles to the abdomen, the antero- 

 dorsal edge relatively long, longer than in awipennis, so that the face 

 of the hamule is relatively broader in icsseana. In inccsta the anterior 

 angle is obliterated in a curve joining the antero-ventral and the antero- 

 dorsal edges, and the face is relatively slender as in iiuripennis. 



In a younger male the labium, genae and mandibles are pale dull 

 yellow, the postclypeus shades out to dark greenish adjacent to the 

 eyes, and there is a green spot on the frons, against the eye, just above 

 this. The dorsum of the thorax is brown with a purplish cast ; the 

 sides of the thorax are largely pale yellow with the posterior two- 

 thirds of the mesepimeron and the upper part of the metepisternum 

 darker, thus defining two more or less distinct pale stripes, one just 

 posterior to the humeral and the other just posterior to the second 

 lateral suture. Dorsum of abdomen similarly paler, 3-6 slightly lighter 

 in color and yellowish adjacent to the lateral carina : 7-9 with a longi- 

 tudinal dorsal black stripe occupying about one-third the area on each 

 side between the middorsal line and the lateral carina (probably in 

 younger individuals this dorsal black stripe is defined on more basal seg- 

 ments) ; 10 and appendages yellowish brown; abdomen beneath, between 

 the lateral and ventral carinae, pale greenish or yellowish on 2 and 3, 

 shading darker to greenish or yellowish brown on the segments poste- 

 rior to 3, a more or less distinctly darker subapical area on either side 

 of each segment; sterna at base of 3 and on 9 and 10 yellowish, other- 

 wise dark to black. 



Coxae pale yellowish to pruinose brown ; legs brown to nearly black ; 

 femora paler at base and with the dorso-posterior surface pale yellowish 

 to brown, darker apically. 



Wings basally, posterior to A and proximal to the distal angle of the 

 triangles, hyaline ; remainder of wing reddish yellow, sometimes slightly 

 more intense in the area between nodus and stigma, the extreme apex 

 very narrowly and inconspicuously dusky tipped , the basal spaces 

 anterior to A are not as deeply tinged as the apical portion of the wing. 

 Venation basal to about the level of the triangles dark to black; distal 

 to this point all the veins are reddish yellow excepting the veins on the 

 anterior and posterior sides of the stigma and the posterior wing margin, 

 which are black; stigma dragon's blood red (Ridgway). For venational 

 characters see following the description of the female wings. 



9 . Labium pale dull yellowish brown ; genae and mandibles green- 

 ish ; labrum yellow with a large median basal rounded black spot which 

 is joined basally on either side with a more or less extensive lateral 

 spot which reaches and extends more or less along the anterior margin 

 but does not attain the lateral margin above; anteclypeus greenish 

 brown ; postclypeus and frons brown to nearly black, each on either 

 side in front,- against the eye, with a greenish or bluish spot; occiput 

 brown; rear of head brown, similar to that of the male. 



Thorax as in the younger males, the sides more uniformly yellowish,
