and less conspicuous; with a medio-longitudinal line, which becomes 

 subcarinate in metazonal portion, but is only slightly heavier at 

 the caudal margin. Pronotal lateral lobes as here described for 

 E. moluccarum (Griffini),but with prothoracic pleurites unarmed. 

 Tegmina short and broad, costal margin showing distinct obtuse- 

 angulation slightly beyond median point, sutural margin rounding 

 broadly, then very fainty and broadly concave (indicating very weak 

 falcation) to the acute apex, situated on the costal margin and 

 forming an angle of slightly less than ninety degrees. Wings 

 failing to reach apices of tegmina by a short distance. Abdomen 

 with distal tergites, excepting the ultimate, each produced meso- 

 caudad in a decided finger-like projection, directed caudad; ultimate 

 tergite with a triangularly impressed area before the triangular 

 supra-anal plate. Cerci elongate, but decidedly shorter than in 

 moluccarum, tapering strongly and straight, then toward apex 

 incurved, the apex terminating in a minute tooth. Subgenital 

 plate elongate produced, but decidedly shorter than in moluccarum, 

 deeply V-emarginate distad, the lateral portions weakly divergent, 

 tapering to their narrowly truncate apices, each of which is sur- 

 mounted by a minute, rounded, socketed style, twice as long as 

 its basal width. Cephalic and median femora rugulose, showing a 

 feeble trace of carination dorso-distad. Caudal femora heavy 

 proximad, dorso-external and ventro-external surfaces weakly 

 concave between the medio-lateral and dorsal carinae, dorsal carina 

 with (two or three) blunt but decided tubercles and a few sub- 

 tuberculations. Ventral femoral margins unarmed. Cephalic 

 tibiae with auditory foramina subconchate. 



General coloration that of a dead leaf. Warm sepia, shading to 

 tawny-olive on sides of thorax and with greater portion of tegmina 

 bay. Limbs blackish, except proximal portions of caudal femora, 

 which pale toward tawny-olive. Vertex immaculate. Antennae 

 blackish, with widely spaced, short buffy annuli. Tegmina with a 

 large blackish spot, meso-proximad in stridulating area; meso- 

 distad with a number of small desiccated-appearing patches.
