length of caudal femur 15 and 16, length of ovipositor 17 to 19.2 mm. 



Togona philippina new species. Plate XV, figure 4. 



Closely related to the Formosan T. unicolor 62 Matsumura and 

 Shiraki, 63 the present females may be distinguished by their slightly 

 smaller size, much smaller pronotum, longer tegmina, shorter 

 ovipositor and the lamellate and much more abundantly spinose 

 ventro-external margins of the median and caudal femora. 



This genus is clearly very near Tympanoptera, differing in the 

 subobsolete medio-longitudinal sulcation of the pronotum, narrower 

 ovipositor which is evenly though weakly curved upward, shorter 

 tegmina with veins not minutely tuberculate proximad, median 

 vein forking slightly beyond end of proximal fourth, greater distal 

 divergence of discoidal and median veins and sinuous ulnar and 

 branch of the median vein. 



Type: 9 ; Surigao, Mindanao, Philippine Islands. (From C. F. 



Baker.) [Hebard Collection, Type no. 818.] 



Size small, form moderately slender, structure delicate. Vertex 

 acute, projecting very slightly beyond antennal scrobes, dorsal 

 surface concave to near apex. Pronotum weakly tuberculate 

 with a weak medio-longitudinal line defined by lateral carinulae 

 which are mainly indicated by tubercles, with two transverse sulci 

 which are not interrupted mesad; caudal margin of disk convex, 

 humeral sinus obtuse-angulate but distinct, other margins weakly 

 tuberculate; lateral lobes higher than wide, ventro-cephalic angle 

 rounded rectangulate, ventral margin very weakly convex, ventro- 

 caudal angle sharply rectangulate. Tegmina and wings fully 

 developed and capable of sustained flight. Tegmina with costal 

 margin broadly convex, sutural margin almost straight to the 

 rather sharply rounded apex at its distal extremity; veins of dis- 

 coidal field parallel in greater part, though the ulnar and branch 

 of the median vein are sinuous, median vein branching slightly 

 before end of proximal fourth and diverging from discoidal vein in 

 distal third; majority of cross- veinlets of discoidal field transverse 

 and straight, those of scapular field irregularly branching and 

 moderately oblique. Supra-anal plate linguliform, medio-longi- 

 tudinally carinate. Ovipositor not heavy for group, curving 



6? Karny has recorded a male from Los Bailos, Luzon, Philippine Islands, as 

 unicolor, having compared it with Formosan males of that species. That in- 

 dividual almost certainly represents the present insect and it is probable that 

 the differences in limb structure were not noted (Philippine Jour. Set., XVIII, 

 p. 610, {1921).) 



63 The figure originally given of unicolor does not show the acute-angulate 

 branching of the median vein, nor the gradual distal divergence of the discoidal 

 and median veins of the tegmina, found in the material here treated. This is 

 probably attributable to faulty drawing.
