I only know this species by two specimens in the Atkinson 

 Collection, and have not seen it in any of the other Indian 

 collections which I have examined. 



2476. Atkinsoniella maculata, sp. n. 



Head, pronotum, scutellum, body beneath, legs and tegmina 

 ochraceous ; two spots on vertex at the region of the ocelli, three 

 spots in transverse series near the anterior margin of pronotum, 

 a spot at each basal angle of scutellum, a central transverse spot 

 at base and two elongate linear spots on posterior lateral margins 

 of face, a central spot on clypeus, central disk of sternum, apices 

 of femora, bases of tibise, and the apices of the tarsi, black ; 

 tegmina with narrow costal margins, a costal spot a little before 

 apex and the apical margin black ; vertex short, about half the 

 length of pronotum, strongly foveate on each side at inner 

 margins of eyes; face foveate on disk, the foveation neither 

 reaching base nor clypeus, the lateral areas transversely striate ; 

 pronotum with a narrow antei'ior collar preceded by a distinct 

 transverse impression ; lateral margins of the scutellum broadly 

 ridged ; tegmina very finely and obscurely wrinkled and punctate. 



Length iucl. tegm. 10 millim. 



Hub. Assam; Shilloug (Coll. Bist.). 



Genus SOIBANGA, nov. 



Type, S. hella, Walk. 



Bistrihution. British India. 



Vertex broad, robust, about half as long as breadth between 

 eyes, centrally, diseally, transversely depressed and a little foveately 

 depressed on each side before eyes ; ocelli on posterior disk a 

 little nearer to eyes than to each other ; face broad, moderately 

 convex, centrally longitudinally subsulcate ; pronotum about as 

 long as vertex, lateral margins nearly straight ; scutellum medially 

 narrowed to apex ; legs slender ; tegmina elongate, somewhat 

 narrow, apical areas four, clavus broad ; wings very broad, their 

 apices subtruncate, two transverse veins before apical area. 



The great breadth of the wings and the structure of the vertex 

 are the salient points of this genus.
