dd. Pronotum or pronotal carina twice intersected by transverse 

 sulci. 

 e. Pronotal carina percurrent, not obliterated between the 

 sulci. 

 /• Pronotum cristate anteriorly; tegmina generally mem- 

 branaceous over most of the apical half. 

 g. Lateral lobes of the pronotum posteriorly rectangulate 

 or obtuse-angulate, the posterior margin descending 

 obliquely forward, their metazonal portion posterior 

 to the typical sulcus, thereby narrowed inferiorly ; 

 prozona posteriorly scutellate on the disc; vertex 

 of the head with a transverse cannula on either 



side next to the eyes Derotmema, Scudd. 



gg. Posterior portion of the lateral lobes of the pronotum 



of equal width throughout. 



h. Inferior margin of the lateral lobes oblique, the 



posterior angle thereby acute or posteriorly 



produced. 



i. Lateral canthi of the metazona terminating at 



the principal sulcus or, if continued, it is in a 



different course ; prozona posteriorly scutellate 



on the disc ; inferior margin of the lateral 



lobes straight, the posterior concave ; tegmina 



fasciate or maculate ; head tumid ; the frontal 



costa moderately constricted Mestobregma, Scudd. 



it. Lateral canthi of the metazona acute, passing in 

 the same course beyond the principal sulcus. 

 J. Disc of the prozona not posteriorly scutellate ; 

 inferior margin of the lateral lobes straight 

 or arcuate, the posterior concave, the angle 

 slightly produced posteriorly ; frontal costa 

 of the head very strongly compressed ; basal 

 half of the tegmina densely coriaceous , . Psinidia, Stal. 

 jj. Disc of the prozona more or less distinctly 

 scutellate posteriorly ; lower margin of the 

 lateral lobes straight and oblique, the pos- 

 terior margin nearly straight, the angle pro- 

 duced inferiorly; head narrow, its frontal 

 costa moderately constricted ; tegmina densely 

 reticulate, fasciate on the costal „margin, the 

 distal third only membranaceous ; . . . Conozoa, Sauss. 

 hh. Inferior margin of the lateral lobes horizontal, but 

 anteriorly oblique, the posterior angle rounded- 

 rectangulate ; disc of the prozona not or scarcely
