h. Costal membrane of tegmiua pvominentlj arched 

 at base and dilated. 

 i. Costal membrane of tegmina much narrower 



than costal area Umjaba. 



it. Costal membrane of tegiuina always as bi'oad 



or broader than costal area Pycna. 



D. Pronotal lateral margins strongly angulately am- 

 pliated, the angular apices reaching the middle 

 or near apex of basal cell of tegmina. 

 hh. Costal membrane not prominently arched at 



base and only moderately dilated Ugada. 



II. Tegmina with numerous, always more than eight, 



apical areas. 

 ; a. Tegmina semihyaline, only more or less reticu- 

 lately veined on apical area ; opercula not quite 



reaching middle of abdomen Anffcaniana. 



aa. Tegmina opaque, venation on apical half dense 

 and furcate ; opercula not extending beyond basal 

 segment Polyneura. 



lOBA, gen. nov. 



Head (including eyes) wider than the base of the mesonotura, 

 not truncate anteriorly, but with the lateral margins ot" the 

 vertex a little oblique on each side and the front prominently 

 produced ; pronotum transverse, its posterior margin only a 

 little less in length than the vertex, the lateral margins 

 strongly and angulately produced on each side, the angula- 

 tions medial, their apices when the tegmina are expanded 

 reaching near or to about the end of the basal cell ; meso- 

 notum about as long as the pronotum ; anterior femora with 

 one or more distinct spines, posterior and sometimes inter- 

 mediate tibiae spined on apical areas ; metasternum elevated 

 and centrally sulcated ; tympana covered ; opercula short, 

 broad, their apices more or less convexly rounded ; rostrum 

 reaching the posterior coxae; tegmina with the basal cell 

 broad, irregular, with four, or sometimes five, angles ; ulnar 

 veins widely separated at their bases ; interior ulnar area 

 somewhat broadened at apex.

 transverse, its posterior margin little more than half the length 

 of veitex, the lateral margins strongly and angulately
