 It is very probable that this is the same as rittata Westwood. 



(2) jaimna sp. n. 



$ Vertex and face narrower than in rittata, but not so narrow as 

 in niakii; a faint Iteel dividing vertex from face. Tegmina broader 

 than in rittata, being produced on hind margin beyond clavus, a char- 

 acter shared by niakii. 



Stramineous or light brown, darlc brown or black between keels of 

 vertex, face and clypeus, and along outer sides of keels, dark mark 

 down first and second coxae, two longitudinal marks on femora, the 

 tarsi and tips of tibiae fuscous, six dark marks down scutellum, ab- 

 dominal segments lightest on posterior edges; tegmina light strami- 

 neous, veins yellow bordered with fuscous, fuscous over radial cell and 

 gradate cross-veins, a round black spot at base of cubitus. 



Ventral edge of pygophor slightly angularly produced in middle, 

 lateral edges forming a broad angular plate, the ventral edge of which 

 is toothed near apex; anal segment quadrate, longer than broad, anus 

 about middle, a small ridge across base, apex forming a flattened 

 surface; styles longer than anal segment, lanceolate, the apices turned 

 upward. 



9 Last abdominal sternite broader than long, posterior edge pro-

(1) pseudornoesta sp. n. 



This species differs from iiior.sta in having the face, antennae, mid- 

 dle of thorax, lateral keels and apex of scutellum and pleura of thorax 

 yellowish; the dark markings on tegmina slightly reduced. 



$ Ventral edge of pygophor produced into small point in middle, 

 anal segment shorter, straight, apex rounded and not turned ventrad, 

 styles long, narrow, edges subparallel except at base where inner edge
