each lateral marginal area being also more or less pale ochraceous ; 

 scutellum very pale ochraceous with a large fuscous spot near 

 each basal angle ; face very pale yellowish-white, its posterior 

 margins ochraceous, cheeks more ochraceous with their lateral 

 margins dark plumbeous ; clypeus ochraceous witli an apical piceous 

 spot ; body beneath and legs plumbeous, the anterior and inter- 

 mediate tibiae and tarsi pale stramineous, postei-ior tibiae plumbeous 

 palely spotted, the posterior tarsi pale ochraceous with the apices 

 of the joints piceous, apices of the anterior femora stramineous ; 

 tegmina greyish-white thickly mottled and punctured with shining 

 fuscous-brown, the claval sutural margin less so and paler, the 

 upper apical area pale plumbeous intersected by the brown veins 

 and with small brown spots ; vertex rounded between the eyes, 

 much broader than long, with a central anterior submarginal 

 impression ; scutellum deflected towards a profound central trans- 

 verse impression ; tegmina considerably longer than abdomen. 



Length $ 6 millim. 



Hah. Ceylon; Hakgala (G^re^n). 



Mr. Green sent me a single example of this distinctly marked 

 species. 



Genus XESTOCEPHALUS. 



Xestocephahis, Van Buz. Tr. Am. Ent. Soc. xix, p. 298 (1892) ; 

 Matsum. Termesz. Fiizetek, xxv, p. 402 C1902) ; Melich, Horn. Faun. 

 Ceylon, p. 205 (1903). 



Type, X imlicarius, Van Duz., a Nearctic species. 



Distribution. Neai'ctic, Eastern Palaearctic, Ethiopian and 

 Oriental Eegions. 



" Head tumid and rounded before, ocelli placed on the I'ounded 

 anterior edge superiorly, distant from the eyes ; vertex convex, 

 closely evenly punctured, without longitudinal ruga;." {Van 

 Duzee.) 



A^ertex broader than long, anterioi'ly roundly produced, the 

 lateral margins in a line with the eyes ; face narrowing to clypeus 

 which is about half its length ; pronotum longer than vertex, 

 convex, strongly deflected on each lateral area, the anterior margin 

 rounded, the posterior margin truncate in front of scutellum and 

 then oblique to the posterior angles ; scutellum broad, its apex 

 somewhat longly acutely produced; tegmina considerably longer 

 than abdomen, their apices angularly rounded, costal margin 

 moderately rounded, three prominent apical cells (sometimes imper- 

 fectly seen), a transverse subbasal vein in clavus ; legs moderate, 

 somewhat slender, the posterior tibiae prominently spinulose. 



This genus may here find a tentative location. A.t present as 

 already mentioned {ante, p. 265) its taxonomic position is not a 

 matter of uniform agreement among Homopterists.
