posteriorly, but practically reaching the posterior margin of pro- 

 notum. Scutellum transverse, with 3 somewhat obscure keels, 

 legmina not nearly reaching apical margin of abdomen, rounded 

 apically. Tibial spur with about 13 teeth. 



I. perkinsi, sp. nov. 



Testaceous, frons embrowned, eyes black. Tegmnia hyaline. 

 Tergites hyaline. Tergites basally more or less pale orange 

 brown, apex more or less black.

Ectopioptcrygodelphax, gen. nov. 



Distinguished by the large, polished, convex pellet of chitin in 

 the middle of the'tegmina. The form of the head is different 

 from that of any other Asiracid known to me. 



Vertex long triangular, longer than pronotum, and longer 

 than its own width at base; lateral margins carinate, meeting 

 anteriorly in a slightly rounded acute angle, well beyond the api- 

 cal margin of the eyes ; median keel present but no other keels 

 dorsally. Posterior margin of vertex slightly roundly emar- 

 ginate. Eyes longer than wide, head and eyes wider than the 

 length of the vertex. Frons suboval, lateral margins rounded ; 

 median keel strong and entire ; lateral keels acute, starting from 

 lateral keel of vertex at a lower (inverted) elevation than the 

 middle keel, so that for at least the basal half of the length of the 

 frons, the middle keel is strongly visible in profile ; lateral keels 

 apically remote from middle keel ; apical margin of frons trun- 

 cate. Genae narrow. Clypeus tricarinate. Antennae very 

 short. Pronotum 'anteriorly rounded, posterior margin I'ghtly 

 emarginate, lateral keels remote anteriorly from middle keel 

 (practically a continuation of the head keels.) Scutehum with 3 

 entire keels. Tibial spur short, with a large number of pale, 

 translucent, ill-defined teeth. 



I. eximiiis, sp. nov. 



Pale green, faintly marked, mostly in interrupted longitudinal 

 lines, with brown. Apex of frons, clypeus. genae (partly), sterna 

 and abdomen, black. Tegmina subhyaline, pale brown; a large 

 spot near the base a wide band across the middle of the corium
