The previously unknown female of minuta differs only from the 

 female of L. cryptisema, here described, in the vertex which is 

 broader proximad, in the immaculare antennae and in the pro- 

 portions of the pronotum, tegmina and ovipositor.

 pronotum 4.8, depth of pronotal lateral lobe 5, width of pronotal 

 lateral lobe 3.9, length of tegmen 39.3, greatest width of tegmen 

 8.7, length of cephalic femur 5.9; length of caudal femur 24.3, 

 length of ovipositor 6 mm. 



Liotrachela iliganae new species. Plate XIV, figures 8, 9 and 10. 



Related to L. minuta Brunner, the male before us differs from 

 the male type of that species in its slightly larger size, broader 

 tegmina, distinctive genitalia and caudal tibiae which have a small 

 dark brown suffusion on their external faces proximad. 



Type: cf, Iligan, Mindanao, Philippine Islands. (From C. F. 



Baker.) [Hebard Collection, Type no. 804.] 



Size slightly larger than minuta, form similar. Vertex much as 

 here described for L. cryptisema, except that it is more evenly 

 declivent. Pronotum as there described, except that it is slightly 

 broader. Tegmina similar except that they are wider, the first 

 branch of the median vein forking mesad. Supra -anal plate weakly 

 produced to a bilobate apex, with emargination between very 

 small and rounded, below which projects the small, acute, trian- 

 gular supra-anal plate. Cerci extending caudad nearly to apex of 

 subgenital plate, proximal portion cylindrical, feebly tapering and 

 feebly recurved; external margin very weakly convex proximad and 

 strongly so distad to the acute, toothed apex, which is horizontal 

 and directed mesad; internal portion of distal half enlarged into a 

 somewhat flattened, rounded triangular projection, the internal 

 margin, from the apex of this projection to the apex of the cercus, 

 strongly concave and armed to near apex with (9 to 11) minute, 

 stout teeth. Subgenital plate with margins moderately convergent 

 in proximal portion, produced in two slender, sharp, straight 

 spikes in slightly over distal third, the interval between these very
