small rounded piceous spots ; vertex of head very finely and 

 obscurely punctate, the apex a little more angulate than in 

 the preceding species, traversed by two central, longitudinal, 

 somewhat obscure impressions; pronotum very obscurely 

 transversely striate; tegraina with the veins subprominent ; 

 wings hyaline, with the veins ochraceous. 



Length, inch tegm., 11 mm. 



Hah. Ceylon [Green). 



This description is based on a somewhat mutilated speci- 

 men sent to me by Mr. Green. It is to be readily separated 

 from L. spatulata by the less concavely sinuate lateral margins 

 of the vertex and by the piceous markings to the tegmiua. 



Amberbakia, gen. uov. 



Vertex of head not so long as pronotum and scutellum 

 together, but a little longer than pronotum, the lateral 

 margins gradually narrowed from in front of eyes to apex, 

 which is subangulate; ocelli near lateral margins a little in 

 front of eyes ; head beneath very foliaceous, face widened 

 and thickened between the antennae, thence anteriorly elou- 

 gately much narrowed and centrally sulcate, and posteriorly 

 less narrowed to clypeus ; pronotum a little shorter than 

 vertex, its lateral margins straight, anterior margin straight 

 but obliquely recurved behind eyes, posterior margin con- 

 cavely sinuate ; scutellum aUiiost as long as pronotum ; legs 

 moderately slender, posterior tibise moderately curved, very 

 long, and outwardly somewhat closely longly spinose ; 

 tegmina broad, costal and apical margins rounded, clavus 

 broad, Avith ti*ausverse veins on its basal area, two elongate 

 discoidal areas, and a series of transv^erse veins before apical 

 area defining longitudinal apical cellular areas.
