light brown with obscure darker shadings ; in brighter individuals 

 these lobes are rich reddish brown above, with a median longitudinal 

 pale blue shading, and the sides blue ; hind border wide, with round 

 lateral wings and a rounded median border of the same height. Pro- 

 pleuron pale, almost white to bright blue. 



Thorax above very variable; in all a dark metallic green middorsal 

 stripe, on either side about one-fifth as wide as the mesepisternum, 

 with the sides parallel, except at the extreme upper and lower ends; 

 remainder of mesepisternum rust red and very variable ; in some the 

 color seems fairly uniform over the entire surface, but in most speci- 

 mens there is a faint hint to a rather definite pale stripe on either side 

 of the median dark green, and of about the same width; this stripe 

 may show as a lighter rust red or parts of it may be greenish or 

 bluish; in life in bright-colored individuals I recall it as an evanescent 

 bright light blue stripe. Sides from the humeral suture light to 

 bright blue ; the mesepimeron usually slightly paler than the mete- 

 pisternum and metepimeron, with a narrow posthumeral darker blue 

 stripe; a small brown dot slightly above the middle of the first 

 lateral suture and another near the upper end of the second lateral 

 suture. In the case of a few very mature specimens the rust red of the 

 mesepisternum has become almost or quite as dark as the middorsal 

 stripe, in which case the pale stripe on either side of the dark middor- 

 sal stripe is distinct and well defined, rusty silvery white in color, the 

 mesepimeron largely overlaid with silvery white, and the under parts 

 and coxae with scattered powdery pruinescence. Coxae and beneath 

 pale, cream or bluish. 



Abdomen seen from above, i blue with a median brown spot which 

 is usually pale centered; 2 blue with a wide longitudinal median brown, 

 more or less black stripe, which is slightly widened basally and 

 apically, not reaching the base which is pale, and usually slightly 

 separated from the narrowly brown apex ; 3 to 6 brown, shading
