straight, produced medially as a small rounded lobule; orange females of J. verticalis 
have the metallic green on the abdominal dorsum covering more of the sides, not 
constricted anteapically, and the basal yellow rings on segments 4-7 much narrower, 
medially interrupted. 
The disagreement with Hagen’s description of the superior appendages of the male, 
noted above, is rather significant, and I cannot explain it, except by suggesting an 
individual abnormality in the type. Mr. Henshaw has kindly compared one of these 
males with the type, and says that the inferiors agree, and they are very characteristic.

As in Ischnura, there are two colour-forms of the female—one black, one orange ; 
the former coloured like the male on the head, the latter coloured more like the male 
on the abdomen. There is but, one known species.
