tf. Dorsal surface of the head blackish, the following blue : a large 

 postocular spot each side, lower margin of the frons, genae, rhinarium, 

 external surfaces of mandibles and labrum. Labrum and rear of head 

 cream -color, or very pale blue. Prothorax obscure blackish, sides and 

 perhaps the front lobe pale blue ; hind lobe produced upward as a me- 

 dian quadrangular process, the width of which is greater than its height. 

 Mesothoracic dorsum blackish-brown, a pale blue antehumeral stripe 

 the width of which at mid-height is about one-third of that of the dark 

 mid-dorsal band and somewhat narrower than the humeral stripe, 

 which latter is dark reddish-brown ; sides and ventral surface pale blue. 



Dorsum of abdominal segments 1-6 black, their sides inferiorly pale 

 blue, green, or yellow, 3-6 also with a narrow transverse basal mid- 

 dorsally interrupted pale ring; 7 chiefly pale blue, with a transverse 

 black band at anterior and at posterior ends, the latter wider, and an 

 inferior lateral longitudinal black stripe on each side connecting the 

 two transverse bands; 8 and 9 blue, 10 black dorsally, ventral sur- 

 faces of 1-10 pale blue, or yellow. Plind margin of 10 with a mid-dorsal 

 bilobed process, the height of which is about one-tenth of that of the 

 segment, and which is quite distinctly marked off from the rest of the 

 segment, as seen in profile view, by a slight constriction as its base. 



Superior appendages not quite as long as 10, quite complicated, 

 blackish ; in dorsal view diverging from each other, each bifid at tip, 

 with outer and inner branches, the latter reaching farther caudad. 

 In profile view three divisions of the distal part of the appendage 

 are visible, two outer and one inner between the other two ; of the 

 two outer, one is above the other, being the outer branch of the dorsal 

 view, and is separated from the lower outer branch by a regular con- 

 cave curve, within which the inner branch of the dorsal view appears. 

 From the ventral surface of the inner branch projects downward a
