ochraceous ; apex of face, a central line and apex to 

 rostrum, bases and apices of anterior and intermediate 

 femora, apices of tibiae, two spots on anterior trochanters, 

 posterior margins of intermediate coxae, a linear streak 

 on intermediate and posterior trochanters, base of abdo- 

 minal segments, and a central longitudinal streak on 

 apical segment, fuscous. Opercula fuscous thickly 

 covered with grey pubescence, and with their posterior 

 margins narrowly ochraceous. 



Tegmina hyaline ; costal membrane and area, and 

 venation ochraceous ; transverse veins at apices of ulnar 

 areas infuscated ; a spot on costa near base, and a 

 smaller one beneath it, two spots in radial area, two or 

 three spots in each of the four upper ulnar areas, 

 fuscous ; apices of apical veins infuscated and thickened 

 at each end. Wings pale hyaline, the veins pale 

 ochraceous. 



The face is broad, slightly convex, with a very broad 

 longitudinal sulcation and strong transverse striations, 

 the upper striae black, their interstices broad- Eostrum 

 long, passing the posterior coxae. The pronotal margins 

 are considerably ampliated, and obtusely angulated 

 about the middle. The opercula are short and broad, 

 their inner margins overlapping, their lateral margins 

 obliquely rounded, their posterior margins convexly 

 rounded and about reaching base of first abdominal seg- 

 ment. Long. (? 31 mm. Exp. tegm. 94 mm. Long. ? 

 (one spec), 37 mm. Exp. tegm. 105 mm.

Malagasia, n. g. 



Head including eyes much narrower than base of 

 pronotum, ocelli situate on disk of vertex and distant 

 from base of head. Antennae moderately long and 

 slender, the first joint strongly incrassated. Pronotum 

 compressed and narrowed towards head, the lateral 

 margins obtusely dentate, the posterior angles amplified, 

 flattened and rounded. Eostrum about reaching poste- 

 rior coxae. Tegmina hyaline, the space between the 

 postcostal vein and the postcostal ulnar ramus amplified 

 towards apex ; apical areas eight, first or upper longer 

 than second, ulnar veins separate and parallel at bases ; 

 the basal area considerably longer than broad. Wings 

 hyaline, with six apical areas. Abdomen globose,
