widely distributed in Brit. India, Burma and Tenasserim. The specimen here figured 

 is of a varietal character, but one which is also found in India. I have (supra, 1908) 

 described the variation of the species. 



228. Jassus determinatus, sp. n. {Plate 51, fig. 16 a). 



Closely allied to J. indicus, but with the face testaceous with a broad central 

 longitudinal black fascia which neither reaches base nor apex, cheeks with a prominent 

 black spot on each side ; rostrum and legs ochraceous, apex of rostrum, apices of 

 posterior tibiae and apices of all the tarsi, black ; posterior tibise finely spotted with 

 black. 



Long, inch tegm. 7 mm. 



Loc. Seychelles. Mahe : Cascade Estate, about 1000 feet. 



A single carded specimen of this distinctly marked and coloured species. 



LiMENTiNUS, gen. nov. 



Allied to Jassus, but with the vertex of head distinctly longer than broad, the 

 apex considerably broader than base, rounded, and distinctly projecting beyond the 

 anterior margins of the eyes, strongly centrally and laterally carinate, ocelli near apical 

 margin, much farther apart from each other than from the lateral apical angles ; face 

 very long, about as long as vertex, pronotum and scutellum together, elongate, very 

 slightly convex, its anterior margin distinctly produced beyond the anterior margin 

 of the eyes ; scutellum small, centrally carinate, less than half the length of face ; 

 other characters generally as in Jassus. 



229. Limentinus aldahranus, sp. n. (Plate 51, fig. 12 a). 



Vertex of head ochraceous, black between the carinations ; pronotum and scutellum 

 black ; body beneath and legs ochraceous ; face and clypeus with broad lateral black 

 fasciae ; apices of the posterior tibiae black ; tegmina dull dark ochraceous, the venation 

 broadly black, costal membrane black, with a longitudinal line before middle, and two 

 prominent longitudinal spots beyond middle, pale ochraceous, the veins on apical ai-ea 

 spotted with pale ochraceous, claval veins also finely spotted with ochraceous ; pro- 

 notum obscurely transversely strigose ; scutellum strongly transversely impressed near 

 middle ; other structural characters as in, generic diagnosis.
