bb. Mesosternal lobes with their inner margins more or less distant. 

 c. Posterior margin of the pronotum rounded. 



d. Tubercle of the prosternum transverse, broad, the apex truncate to

dd. Tubercle of the prosternum conical, more or less acute. 



e. Body very graceful, or slender. The front strongly oblique. 

 Head much exserted, conical. Antennae distinctly ensi- 

 form. Eyes rather elongate, viewed from above strongly 

 convergent, meeting at an acute angle. Pronotum dis- 

 tinctly dilated posteriorly, the lower edge of sides straight, 

 oblique. Tegmina plainly dilated towards the apex. 



Inusia Giglio-Tos. 

 ee. Body more robust. Front less oblique. Head only gently ex- 

 serted, not conical. Antennae filiform, or with immediate 

 basal segments alone flattened. Eyes not at all, or but 

 little, elongated, when viewed from above slightly con- 

 vergent, forming an obtuse angle. Pronotum not, or 

 but little, dilated posteriorly; the lower edge of sides straight 

 on posterior half, emarginate on anterior half. Tegmina 

 narrowed toward the apex. 

 /. Pronotum cylindrical, the dorsum straight viewed laterally, 

 the metazona not elevated. Frontal costa below the 

 ocellus and the lateral carinae of the face subobsolete. 

 Eyes rather oblique, less prominent. 

 g. Head back of the eyes not narrowing posteriorly; eyes less 

 prominent; antennae somewhat incrassate, the immedi- 

 ate basal joints flattened; anal field of tegmina pallid. 



Mesosternal lobes distant Stenopola Stal. 



gg. Head back of eyes narrowing posteriorly; eyes strongly 

 prominent. Antennae linear; tegmina ferruginous, the 

 anal field concolorous. Mesosternal lobes less distant. 



Oxyblepta Stal. 

 ff. Pronotum gently dilated posteriorly, the dorsum when viewed 

 laterally sinuate, subselliform, the metazona gently ele- 

 vated, the humeral angles rather distinct. Frontal costa 

 and lateral carinae of the face distinct. Eyes less oblique 



and strongly prominent Henia Giglio-Tos. 



cc. Posterior margin of the pronotum obtusangulate, sometimes truncate, 

 entire, or emarginate at middle. 

 d. Angle of the posterior margin of the pronotum entire, not incised. 

 Tegmina greatly surpassing the hind femora. 

 e. Tegmina with their apices subacuminate. Frontal costa not 

 prominent between the antennae. Eyes less strongly con- 

 vergent and not distant from anterior edge of pronotum.
