ocular spots. Labium. pale yellow. Labrum shining black, 
but its anterior margin broadly yellow (so that it is half 
black, half yellow) ; a broad yellow band occupies the vertical 
portion of the rhinarium ; margins of the orbits in front broadly 
yellow ; basal joint of antenne yellow beneath, and there is 
a yellow spot below it; back of the head black. 
Prothorax black, yellow at the junction with the head, 
with a large yellow spot above the anterior legs. In the male 
the posterior margin is gently rounded, with a minute median 
notch, narrowly yellow, which expands into a spot on either 
side. In the female the margin is thickened and broadly 
yellow, slightly elevated in its middle, with a distinct median 
notch in the centre of the elevated portion ; in this sex there 
are two small round discal yellow spots (which are absent in 
the male). 
Thorax bronzy green above. In the male there are four 
small yellow spots, two anterior and two posterior (with or 
without humeral lines) ; in the female there is a distinct nar- 
row yellow humeral line, connected with the spots anteriorly 
but abbreviated posteriorly. Sides yellow, with a broad black 
median band, which is furcate towards the anterior wings and 
encloses a yellow spot. Pectus black, yellow in the centre. 
Legs black, femora and anterior tibie yellow beneath ; 
spines black, long and divaricated, seven or eight on posterior 
tibiee. 
Abdomen slender, bronzy green above, passing into yel- 
lowish at the sides and ventrally. First and second segments 
broadly yellow on the sides, enclosing on the first a greatly 
curved black line, which is nearly circular in outline; ali the 
segments from the second to ninth with a narrow anterior 
yellowish sutural ring, which passes into obscure reddish on 
the apical segments; tenth segment nearly wholly obscure 
reddish. 
6. Margin of tenth segment broadly excised in the middle. 
Superior appendages slightly longer than the segment, nearly 
forcipate, stout, the apices curved inward and obtuse, divari- 
cate, internally much dilated in more than the basal half 
beneath ; black externally, the dilated internal basal portion 
reddish. Inferior appendages nearly one half shorter, elon- 
gately triangular, but gradually attenuate and nearly acute, 
turned upward and inward; black, but reddish at the base. 
9. Appendages short, black, conical. Valvules large, 
reddish, their appendages short.
