rupted basal rings on 3-7 ; an apical ring widening into a quadrate 

 median spot on 7 ; all of 8 excepting a very narrow basal ring ; all of 9, 

 the blue narrowed at either side near the middle ; two small round basal 

 spots on 10, and the extreme tip of the elevated posterior margin of the 

 segment which is also blue underneath. Sides of 1 and 2 blue and black ;

 bordered below with blue. Dorsal posterior margin of the tenth segment 

 moderately elevated and produced, the apex scarcely bifid. 



Abdominal appendages black, resembling tho?e of /. verticalis Say, 

 but slenderer and longer. Superior appendages lamellate, sinuate, about 

 half as long as the tenth segment, rounded triangular in form, the depth 

 at base equal to the sides ; the upper, outwardly rolled half scimitar- 

 shaped in profile, and lying above and outside of the upper process of the 

 inferior appendage ; the lower, inwardly rolled half lying inside of the 

 upper half of the inferior appendage. Inferior appendages longer than 

 the superior ; the lower outer two-thirds produced into a slender process 

 curving downwards, outwards and inwards, the extreme apex turned 

 upwards and inwards and tipped with a small shining tooth ; the upper 

 third produced upwards and backwards into a triangular lobe, about one-
