far from maturity ; some doubt exists about the existence of a male 

 form that remains hyaline throughout the imagiual life. Of the series 

 here described, 6 males are banded, 7 hyaline. 



? . Very similar to male in colour and pattern. On the prothorax 

 an anterior transverse yellow band ; the humeral and lateral yellow 

 bands very slightly broader than in male. Abdomen shorter and 

 much stouter ; a broad yellow lateral band from base to segment 8, 

 a narrow one on 9. Wings hyaline in all specimens examined.

c? (adult). Labium yellowish brown. Occiput bronze black. 

 Labrum metallic green ; auteclypeus, base of mandibles and medial 

 half of geuae yellow ; postclypeus dull reddish brown. Dorsal side of 

 head dull black with a greenish metallic lustre between the eyes and 

 ocelli. Prothorax black, two broad lateral bands and the anterior 

 third entirely dull ochre brown. Thoracic dorsum bronze black ; a 

 broad eutii'e oblique greyish ochreous humeral baud, in front of the 

 ventral end of humeral suture, divided in two about equal halves by 

 the dorsal end of the same. Mesepimeron bronze black not fully to 

 the ventral end ; rest of sides ochreous yellow with an indistinct 

 brownish shade on dorsal end of mesepisternum and metepimerou. 

 Ventral side ochreous yellow ; a rather broad lateral brown stripe at 

 the anterior half of metasterua. Legs ochreous ; antero-external side 

 of femora, ventral side of tibiae, tarsi and spines black. 



Abdomen dorsally dull reddish brown with metallic gi'een lustre, 

 this metallic colour shading to darker bronze towards the end ; a 

 broad but somewhat diffuse terminal blackish ring on segments 3-7. 

 Appendages black, very much like the following species. 



Wings with opalescent white and smoky brown bands, as described 

 in key, and illustrated in Plate VII, fig. 5. Pterostigma broad and 

 comparatively short; the proximal part blackish, the distal rich 

 ferruginous ; the proportion of both colours somewhat variable. 



One immature specimen (S. Afr. Mus.) shows the opalescent band 

 alone, with no trace of smoky brown ; it is very probably of the same 

 species ; the terminal abdominal segments are lost.
