Orchesia saltatoria, n.sp. 
Short, robust, convex, shining. Dark castaneous, legs and 
antennae slightly paler. Moderately densely clothed all over with 
short brownish-yellow pubescence, shortest at apex of elytra, 
longest on prothorax. Feebly transversely punctate-strigose all 
over. 
Head somewhat triangular in shape; antennae thickening to 
apex, passing intermediate coxae, 1st joint one and a half times as 
long as 2nd, 2nd-3rd subequal, longer than those following, 4th- 
6th short, subcylindrical, 7th-llth broader, flat, 11th about twice 
as long as 10th. Prothorax much wider behind than in front; 
broadly and feebly bisinuate, and with a shallow depression on 
each side of the base; median line invisible. Scutellum small, 
broadly transverse. Elytra about two and a half times as long 
as wide, a very feeble depression on each side of suture, most 
visible towards apex. Posterior tibiae short, thick, their spurs 
stout, almost equal, as long as themselves, and about three- 
fourths the length of first tarsal joint; tarsi with the basal joint 
distinctly longer than tibiae, or the three following joints com- 
bined. Length 3|, width 1 J mm. 
Hab. — Porest Reefs. 
I have nine specimens under examination, in the size of which 
there is but very little difference. I suppose I must have the 
sexes, but I cannot distinguish them; the species comes closest to 
0. Macleayi, but its much smaller size, broader form, &c, will 
easily separate it from that species. All my specimens were taken 
on tops of posts at dusk; they hopped immediately the hand was 
brought near them, and in this way I lost many others.
