and an antehumeral stripe which is widened inwards at 

 its upper end — light green. Sides pale green with ill- 

 defined pale brown stripes on the two lateral sutures. 



Legs blackish, anterior femora green inferiorly. Tar- 

 sal nails toothed inferiorly before apex, tooth shorter than 

 nail tip, hence departing from the normal form of Ma- 

 crothemis. Second and third femora with teeth as de- 

 scribed for M. imitans. 



Abdomen blackish, 1-5 with a pale green stripe on 

 each side of dorsum, this stripe usually interrupted by the 

 black additional transverse carina (2-3) or suture (4-5); 

 6 in some cases with a small basal spot each side, 7 wnth 

 a large oval spot each side, 8 with or without a small spot 

 each side — pale green. Abdomen somewhat widened at 

 base, thence gradually narrowing to 4, 4-5 of uniform 

 width, 6-7 distinctly widened, 8-10 successively narrower. 

 Ventral surface pale, lateral margins of segments and the 

 sterna blackish. 



Superior appendages black, a little longer than 9, rather 

 slender, an inferior, median tooth whose basal side is 

 denticulated and forms an acute angle with the append- 

 age, apical side of the tooth entire, nearly at right angles 

 to the appendage; apex of the appendages acute, di 

 rected slightly upwards. Inferior appendage about one- 

 fifth shorter, triangular, slender, sides (viewed from be- 

 low) nearl}' straight or slightly concave, apex narrower, 

 with two minute denticles. 



Genitalia of 2 similar to those of J/. cchp)io Selys. 

 Anterior lamina with its margin entire or but very slightly 

 excised in the middle. Hamule more prominent than the 

 adjacent parts, but both absolutely and relatively shorter 

 than in celceno, not bifid, its apical portion forming a slen- 

 der, acutely -pointed hook which is directed backwards. 

 Genital lobe least prominent, wider than long.
