DISTANT— RHYNCHOTA. PART II: SUBORDER HOMOPTERA 309 



Melichar has recently described and figured a Javau species under the name of 

 Oncopsis nigritus (Notes Leyden Mus. xxxvi. p. 121, PL 3, fig. 9) which should either 

 be included in Nehela, or otherwise that generic name should give place to Oncopsis 

 Burm. (1837). But as Burmeister gives as typical Oncopsis the lanio Linn., it cannot 

 very well apply to nigritus Melich. which I regard as an undoubted Nehela.

 Estate, forest, above 1000 feet; Anonyme Island. Also found in Ceylon, Brit. India,

Jacobi's figure (supra) appears, at least, to represent a variety? 



212. Nehela spectahilis, sp. n. (Plate 51, fig. 27 a). 



Ochraceous ; two spots on vertex of head, an oblique line on each side of pronotum 

 from inner margins of eyes and two large spots at base of same, a spot at each basal 

 angle of the scutellum, and a broad submarginal fascia to the tegmina — united to 

 the margin near base — black ; body beneath and legs ochraceous ; face with two spots 

 on apical margin, an oblique spot behind eyes, followed by an elongate spot on each 

 side before clypeus, three spots on disk, and a central fascia to clypeus, black ; sternum 

 and base of abdomen black ; structure of face better shown by the figure here given. 



Long. incl. tegm. 5 mm. 



Loc. Seychelles. Mahe : Mare aux Cochons district, 1000 — 2000 feet. 



A single specimen of this handsome species was alone found in this collection. 



213. Nehela elegantula, sp. n. (Plate 51, fig. 24 a). 



Ochraceous ; two spots on vertex nearly equidistant from eyes and from each other, 

 between them a central longitudinal line, a large spot on each side of pronotum 

 before middle, between them a central longitudinal fascia, and a curved anterior 

 fascia on each side behind eyes, a spot at each basal angle of scutellum and a transverse 

 spot on disk ; tegminal veins and a very broad submarginal fascia, two anterior marginal 

 spots to face and two smaller spots beneath them, a curved marginal spot on each 

 side behind eyes and a spot at apex of clypeus, black ; vertex of head narrow, sub- 

 conically rounded anteriorly ; anterior tibise and tarsi pale fuscous. 



Long. incl. tegm. 5 mm. 



Loc. Seychelles : a fairly long series, entirely from the endemic forests. Silhouette :
