dividual variation and in consequence indicate the above synonymy. 

 Kirby, in 1906, placed obesus as a synonym of fortis. 52 In the 

 present material the dorsal surface of the caudal femora shows a 

 row of minute, blunt denticulations in the s )ecimen from Surigao, 

 this surface' being smooth in the others, though showing a sub- 

 obsolete undulation in the female from Los Banos. 



The insect is smaller and more inflated than the other members 

 of the genus, in general appearance resembling much more closely 

 Cratylus fenestratus (Stoll). 53

Nearest in relationship to C. neriifolius (Stoll), the present 

 species differs in the male sex in the somewhat larger size, more 

 elongate tegmina which are not ocellate, distinctive armament of 

 the median and caudal femora and caudal tibiae. The only 

 markings are a few large brown dots on the tegmina and a curved 

 brown line in place of an ocellate marking.

[Hebard Collection, Type no. 812.] 



Size medium, form slender for this genus of large and very robust 

 insects. Vertex with dorsal surface depressed mesad, small, 

 triangular and scarcely projecting beyond plane of face; as char- 

 acteristic of genus. Pronotal surface thickly supplied with small, 

 acute granules, showing two distinct transverse sulci ; caudal margin 

 of disk weakly and bluntly angulate at slightly over ninety degrees 

 and supplied with a few low tubercles; lateral lobes with ventro- 

 cephalic and ventral portion of margin strongly tuberculate. 

 Tegmina inflated, but by no means as much so as in C. fortis 

 (Walker), costal margin rather decidedly convex meso-distad, 

 mediastine vein oblique. Prosternum unarmed. Cerci stout, with 

 a sharp distal spine directed mesad. Subgenital plate very slenderly 

 produced, with styles at apices, as long as and slightly stouter than 

 the produced portion, forming a Y. Ventral margins of cephalic

54 Estimated, as the great convexity of the tegmina prevents the exact measure- 

 ment being taken. 



56 The measurements given by Brunner indicate a very great possibility that 

 the largest female which he studied does not represent the present species. It 

 seems doubtful also that the same species occurs both in the Philippines and the 

 Moluccas.
