DISTANT— RHYNCHOT A. PART II: SUBORDER HOMOPTERA 311 



lateral margins and veins to tegmina, head beneath, sternum and legs, ochraceous ; face 

 with a short central longitudinal fascia, a spot on each side of anterior margin, a large 

 spot on each side behind eyes and apex of clypeus, black ; anterior tibiae fuscous ; vertex 

 of head more evenly rounded than in preceding species. 



Long, inch tegm. 4^ mm. 



Log. Seychelles. Silhouette : near Mont Pot-£l-eau, highest forest, over 2000 feet ; 

 Mare aux Cochons, plateau and forest above. Mahe : top of Mount Sebert, nearly 

 2000 feet. 



A superficial but constant characteristic of this species is the posterior pale sub- 

 marginal fascia to the pronotum. 



218. Nehela aterrima, sp. n. (Plate 51, fig. 22 a). 



Head above, pronotum, scutellum and tegmina black, vertex with fine obscure 

 yellowish streaks on each side near eyes ; lateral margins of scutellum and outer 

 and inner margins of tegmina pale ochraceous ; body beneath and legs pale ochraceous, 

 face with a transverse anterior marginal fascia (sometimes broadly centrally longi- 

 tudinally continued as in figure, or with the anterior transverse fascia only), anterior 

 tibise, apices of anterior tarsi, and transverse abdominal fascise, black. 



Allied to the preceding species N. JlavoUneata from which it differs by the different 

 structure and markings of the face as shown in figures, smaller size, and more melanic 

 coloration. 



Long, inch tegm. 4 mm. 



Loc. Seychelles. Silhouette : near Mont Pot-a-eau, over 1000 feet. Mare aux 

 Cochons, plateau and jungle above. Mahe : high forest of Morne Blanc ; country 

 above Port Glaud, about 500 — 1000 feet; high damp foi-est at summit of Morne Pilot, 

 over 2000 feet; Mare aux Cochons district, 1000 — 2000 feet; Cascade Estate, forest, 

 above 1000 feet, and forest near Mount Harrison, 1700 feet; slopes of Morne Seychellois, 

 about 1500 — 2000 feet. Felicite Island: from forest. Very numerous throughout the 

 mountain-forests of Mahe and Silhouette. 



Subfamily Tettigoniellinse. 



This subfamily is represented by four genera, two of which are described for 

 the first time, the other two being originally recorded from British India where the 

 Tettigoniellinae are well represented. The Seychelles with only four genera and five 

 species are poorly illustrative of the subfamily in which the Oriental region is so rich, 

 and the Ethiopian region more moderately opulent. In the "Fauna Hawaiiensis," 

 Kirkaldy only enumerates one species and that one he had not seen himself. 



Genus KoLLA. 



KoUa Dist., Faun. Brit. Ind. Khynch. iv. p. 223 (1907). 



This genus has a very wide distribution and is found in the Ethiopian, Oriental, 

 Australasian and Neotropical regions, especially in the last.
