from Than-Moi, Tonkin, alone, by Krausze and Carl. We are 

 told by Dohrn 5 that one of the former's species is referable to 

 Hemielimaea and another to Ducetia. We believe, however, that 

 the numerical abundance of the species of Elimaea in Indo-China 

 is very large. 



In Brunner's key 6 the species runs nearest to appendiculata 

 Brunner. The insect is large, with comparatively broad tegmina 

 for the genus, though not as large or with tegmina as broad as in 

 E. insignis (Walker). 



Type: cf; Phuc-Son, Annam. November to December. (From 

 H. Fruhstorfer.) [Hebard Collection, Type no. 783.] 



Cephalic femora slightly compressed and distinctly curved in a 

 Phasmoid manner; dorsal surface convex, but with its internal 

 margin weakly ridged, except in the more slender proximal portion. 

 Cephalic coxae unarmed. Foramina of cephalic tibiae flattened 

 conchate. Tegmina with median vein branching at end of proximal 

 third, this branch sending three branches to the sutural margin 

 distad. Pronotal disk with surface weakly convex to flattened 

 caudal portion, lateral margins very broadly and evenly concave, 

 the least width of disk meso-cephalad; lateral lobes slightly longer 

 than greatest (caudal) depth, ventral margin weakly concave in 

 cephalic half, weakly convex in caudal half, these portions forming 

 a very weak rounded angulation at their juncture. Tegmina and 

 wings fully developed, the former with greatest width decidedly 

 greater than pronotal length, narrowing very slightly and evenly 

 to the broadly rounded apex. Femora with genicular lobes bi- 

 spinose. Caudal femora with dorsal surface deplanate in proximal 

 three-quarters. Ventral femoral margins armed with minute 

 but rather broad spines, as follows. Cephalic internal 11 and 12, 

 cephalic external 6, median internal 0, median external 15, caudal 

 internal and 1, caudal external 12 and 15. Supra-anal plate 

 elongate shield-shaped, with apex narrowly acute-angulate. Cerci 

 cylindrical, curved and gradually tapering to near apex, where 

 they are briny enlarged, the external margins showing weak emar- 

 gination at base of this enlargement, the apical enlarged portion 

 with a low, longitudinal ridge extending to the apex, which there 

 projects as a short, stout tooth. Subgenital plate elongate and 

 slenderly produced, cleft for slightly over half its length, the two 

 distal portions thus formed slender, parallel, curving very weakly 

 dorsad, of nearly equal width in distal portions to their rounded 

 apices. 



Occiput and disk of pronotum victoria lake, this continued along 

 the sutural margin of the tegmina as a broad suffusion, narrowing 

 and disappearing near their apices. Disk of pronotum showing a
