soine IIcmi])tera-IIo}noptcra. 175 



This species is allied to the Madagascar form, P. guttu- 

 lata, Sign. ; the tegmina are, however, much narrower 

 and much less arched on the costal edge near base, the 

 lateral edges of the thorax differ in being pointedly acute, 

 the rostrum is longer, ground colour much darker and 

 markings different, though the general pattern is much 

 followed. 



Genus ToSENA, Amyot and Serville. 



Tosena albata, n. sp. 



General colour and markings of T. melanoptera. White ; 

 but tegmina with five longitudinal whitish fascia situated 

 between the veins commencing near base, two of which 

 amalgamate with the broad central transverse band, and 

 a subapical row of five irregular longitudinal fascise of 

 the same colour, the first of which is placed at about one- 

 third the length of outer border from the apical point of 

 tegmina, and the last is fused into the central band near 

 the inner margin. Wings as in T. melanoptera, but 

 with a submarginal row of nine whitish fasciae, com- 

 mencing near costa, of which the seventh and ninth are 

 the largest, the last very much so; two-thirds of the outer 

 border narrowly edged with the same colour. 



$ . Long. 59 mill. ; exp. tegm. 132 mill.' 



N. W. Himalaya. 



This species is also smaller than T. melanoptera, with 

 the tegmina narrower and rostrum quite reaching the first 

 abdominal segment, which is not the case in the males of 

 that species. The apices of the femora are not luteous. 



CERCOPIDA. 



Genus Cosmoscarta, Stal. 



Cosmoscarta andamana, n. sp. 



Sanguineous, thickly and finely punctured ; tegmina, 

 with a broad band across centre and apex broadly, black : 

 these bands are united at inner margin, in some specimens 

 very broadly so. Wings sordidly hyaline, with the veins 

 much darker; base slightly sanguineous. Femora, tibia3 

 and tarsi, piceous, hind tibia armed with an acute spine. 



Long. 9 mill. ; exp. tegm. 24 mill. 



Andaman Isles. 



Allied to C. heros, Fab., with which, liowever, it 

 cannot be confused.
