This, the largest Pseudophyllid known, is closely related to 

 C. titan (White). In addition to the larger size, the male before 

 us differs from that sex of titan in the smaller number of equally 

 decided pronotal tubercles, the much broader and much more 

 inflated tegmina, median femora which are smooth dorsad and 

 caudal femora armed with a row of minute blunt tubercles dorsad 

 instead of stout spines. The ventral femoral margins are also 

 much less strongly armed with much smaller spines, none of which 

 show any tendency toward lamellation. 



Type : cf ; Sandakan, British North Borneo. (From C. F. Baker.) 

 [Hebard Collection, Type no. 813.] 



Size very large and robust. Vertex as in C. dyaka here described. 

 Pronotum with surface mesad supplied with (about thirty) stout, 

 blunt, prominent tubercles, with two very deeply impressed trans- 

 verse sulci; caudal margin of disk weakly and bluntly obtuse 

 angulate and supplied with a few low tubercles; lateral lobes with 

 margins strongly and thickly tuberculate, these tuberculations 

 longest on cephalic margin. Tegmina very large and strongly 

 inflated; costal margin broadly convex, sutural margin showing 

 broad concavity meso-distad, thence broadly convex to the rather 

 strongly rounded apex; mediastine vein oblique. Prosternum 

 unarmed. Cerci and subgenital plate as in dyaka, except that the 

 styles are narrowly paddle-shaped. Ventral margins of femora 

 armed with small spines, those of the caudal femora being more 

 elongate distad, as follows. Cephalic internal 3 and 4, cephalic 

 external 0, median internal 6 and 7, median external 5 and 6, 

 caudal internal 13 and 14, caudal external 11 and 12. Spines on 

 caudal tibiae likewise small and slender, showing no lamellation. 



General coloration light green. Antennae with brown suffusions 

 forming elongate, vague annuli. Tegmina in proximal area between 

 anal and ulnar veins with a large opaque, buffy, circular marking, 

 margined with brown and with a dot of brown in its centre; branch 

 of median vein, from near its base, showing a very slender brown 

 line. 



Length of body 56, length of pronotum 17.6, greatest width of 

 pronotal disk 16.3, length of tegmen 99.3, approximate width of
