line on each lateral area, and slightly longitudinally ridged 

 before the connexivnm, M-hich is broad and distinct ; poste- 

 rior femora less longly and strongly sulcate beneatb, posterior 

 tibiae slightly not considerably longer than the femora as 

 in Makonaima, and with a single spine beyond the middle ; 

 tegmina three times as long as broad, not prominently arched 

 at base. 



Type, N. insignis, Dist. 



The large and broad vertex is the character which princi- 

 pally allies this genus to Makonaima. 



Neomonecphora insignis, sp. n. 



Vertex and pronotura brownish testaceous ; scutellum, 

 abdomen above, body beneath, and legs black ; face and 

 lateral margins of prosternum brownish testaceous ; tegmina 

 brownish ochraceous, apical half of costal area, apical margin 

 narrowly continued to apex of clavus, and a rounded sub- 

 costal spot before middle black, posterior margin of clavus 

 piceons brown ; wings fuliginous ; pronotum distinctly 

 broadly foveately depressed on each side of anterior area, 

 its anterior lateral margins somewhat broadly reflexed ; 

 scutellum somewhat faintly transversely striate, the di^k 

 very strongly foveately depressed; other structural characters 

 as in generic diagnosis.

Makonaima, gen. nov. 



Vertex as long as breadth between eyes, centrally longi- 

 tudinally carinate, transversely impressed before the eyes, 

 the lateral margins before eyes lobately convex, their edges 

 ridged and raised upwardly, and somewhat abruptly separated 

 from the apical margin, which is broadly transversely convex, 

 and also distinctly separated from the lateral margins of the 

 central area or lobe, the margins of which are ridged; ocelli 

 placed on each side of the central carination at less than 

 one-third from base ; face somewhat globose, compressed, 

 centrally longitudinally ridged, deflected in front to a more 

 or less acute point, and then obliquely directed backward to 

 the base of the clypeus, which does not quite reach the 

 antericjr coxse ; pronotum about as broad between the lateral 

 angles as its length and that of vertex taken together, 

 rounded and somewhat gibbous on basal area and then 

 suddenly and obliquely deflected towards head, the anterior 

 lateral shorter than the posterior lateral margins, the former
