In this species the colours are somewhat variable. When the tints are well defined, the tergites are adorned 
laterally with a wide, deep green band, and with a much narrower band of the same tint in the dorsal 
middle line; this median band is not complete behind, just falling short of the stomata; the stoma- 
saddles are flavous or pale olivaceo-flavous, the colour being continuous with a wide band on each side 
of the middle line, separating the median from the lateral green band. The legs have their femora, 
patella, and tibiz more or less distinctly ringed with deep green. Tarsi and antenne ferruginous. 
In some specimens the legs are nearly concolorous, of a deep green, and the bands of the dorsal surface become 
more or less fused. 
Head very flat between the eyes; the posterior portion swollen laterally, flat in the middle, the median flat 
area being continuous with that between the eyes. 
Tergites closely spicular, and very evenly convex, being hardly noticeably undulated at the sides; the stoma- 
saddles are ill-defined, and the stomata are inclined and short; the hinder borders of the tergites mesially 
emarginate, 
* Written Anartiostigmata by Silvestri; but this form of the neuter plural is, I believe, etymologically 
incorrect. Compare Echinoderma, sometimes written Echinodermata.
