J (Burmeister’s type). Face pale green, frons superiorly and 
vertex metallic blue, labium yellow, its median lobe and the extreme 
bases of the lateral lobes blackish. Eyes in contact for a distance 
less than the length of the occiput which is brownish above, green¬ 
ish behind. Rear of eyes varied with brown and green. Protho¬ 
rax pale brown. Thorax dark brown, mid-dorsal carina yellowish, 
a complete pale green antehumeral stripe situated half way between 
mid-dorsal carina and humeral suture and whose width is little more 
than the thickness of the carina, but which is abruptly widened on 
its inner side at its upper end, in front of the antealar sinus, so as 
to almost reach the same carina. Sides with four green spots, one 
oblong on the lower part of the mesepimeron, a larger and more 
irregular below the base of the front wing, a triangular on the 
lower part of the metepimeron, and, smallest of the four, a double* 
spot below the base of the hind wing. 
Legs reddish brown, blackish interiorly. Third tibiae with the 
spines of the posterior inner row slightly more numerous (14-15), 
a little shorter, but hardly stouter than those of the anterior (outer) 
row (11-12). 
Abdomen slightly narrower at 3 (.8 mm.) than at 2 (1.7 mm.) 
thence gradually widening to apex of 9 (1.5 mm.), which is slightly 
wider than 10; black spotted with pale green as follows: a double 
spot on either side of the middle of the dorsum of 2, a longitudinal 
stripe on either side of dorsum of 3-8 at base, interrupted by the 
additional transverse carina on 3 or suture on 4-7, pointed poste¬ 
riorly, not longer than half the segment, and an inferior basal spot 
on either side of 3 below the preceding. An indistinct pale streak 
just above the lateral carinae of 3-9. 
Sup. apps. brown, almost as long as 9 + 10, curved somewhat 
downwards, thickened before the acute apex, the thickening being 
greatest at two thirds the length of the appendage where there is a 
small, but distinct, inferior tooth. 
Inf. appendage one fifth shorter, about 1J times as long as width 
at base, apex narrow, ending in the usual two upturned denticles. 
Genitalia of 2 : anterior lamina with somewhat conical profile
