scarcely longer than broad, conical, taperin 2; rapidly; remaining joints 

 filiform, the antennte being much longer than the body. Pronotura 

 selliform, exceedingly contracted in the middle; the anterior and pos- 

 terior extremities greatly elevated, covering the head and base of the 

 tegmina, furnished along the lateral carlnie with half a dozen long, 

 acuminate, curving spines ; presternum with a pair of straight acicu- 

 lar spines. Fore femora longer than the middle pair, both provided 

 at the apex, the former anteriorly and a little interiorly, the latter 

 posteriorly and a little exteriorly, with an extensive spinous and 

 deeply serrate, laminate expansion nearly three times as broad as the 

 femora; bases of the fore and middle tibite compressed into similar 

 foliate expansions, but not so greatly nor so unequally as the femora; 

 otherwise these limbs are quadrate, sulcate superiorly, enlarged a little 

 at the apex ; hind femora exceedingly long and slender, cylindrical, 

 scarcely larger at the base than at the apex, provided apically on 

 either side with a stout divergent spine, and along the entire under 

 surface with a double row of obliquely divergent spines; hind tibiaa 

 conspicuously longer than the femora, slightly sulcate above, the api- 

 cal spines no larger than the others ; first and second tarsal joints 

 bluntly carinate above, the second and third with lateral lobes, those 

 of the third joint larger, bluntly acuminate apically, partially embrac- 

 ing the cylindrical base of the last joint. Tegmina large, exceedingly 

 broad, not so long as the abdomen, erect, the edges broadly eroded, 

 especially below near the apex, the principal vein very prominent, 

 the whole bearing a striking resemblance to a dead leaf; the dorsal 

 and lateral fields are sharply separated by a prominent ridge ; wings 

 longer than the tegmina, the exposed portion resembling them. Ab- 

 domen very stout, with a single mediodorsal series of small, back- 

 ward directed spines at the apices of the joints ; ovipositor exceed- 

 ingly broad, compressed, turned abruptly upward in the middle and 

 then rapidly tapering to a point. 



This genus, which belongs to the Phyllophoridae, is very distinct 

 from any other known to me, but is evidently allied, not very dis- 

 tantly, to Hetrodes. It is even more hideous in its appearance, and 

 the close resemblance of its tegmina to a dead leaf with the foliate 

 expansion of the two anterior pairs of legs renders It a most striking 

 object. A similar insect, from Silhet, is figured (PI. VI, fig. 2) in 

 Wood's '• Insects abroad " and called there Sanaa imper talis; but it 

 differs entirely from the Acanthodes imperialis of AVhite.
