THAMNOTETTIX (Zett.), Scott, Fieb., p., J. Sahlberg, p. 



For tlie most part elongate, slightly dilated across tlie middle of 

 tte elytra. 



Head — croivn : measured tlirougb the centre equal to or more 

 than half the length of the basal margin ; sides in front gently rounded 

 to the centre, which is itself rounded. Ocelli placed close to the front 

 margin and near the eyes. Face moderately convex. AntenncB short, 

 second joint cylindrical. 



Thorax — pronotum twice as broad as long ; anterior margin con- 

 vex ; j^osterior margin straight across the scutellum, from thence to 

 the short lateral margins acutely rounded. Scutellum triangular ; 

 apex acuminate. Eli/fra as long as or longer than the abdomen ; apical 

 areas, four. Wincjn : first and third longitudinal nerves entire, second 

 furcate at or just beyond the middle ; first concave next the apex, and 

 joined to the anterior branch of the second nerve by a short transverve 

 nerve ; third joined to the inner branch of the second nerve at a short 

 distance from the furcation by a short transverse nerve. 



Abdomen : geiiital valve short, triangular ; genital plates elongate 

 triangular, apex narrowly rounded, reaching to the end of the last 

 segment. 



A. Testaceous Species. 



Elytra lanceolate, witliout red spots or atoms, pale testaceous ; nerves 



almost white. 



Crown sometimes orange-reddish, with a short black streak on each side of tlie 

 middle of the anterior margin, and a ■whitish longitudinal streak down each 

 Bide of the centre. Pronotum and scutellum sometimes orange-reddish, the 

 fonner with five, the latter with three, longitudinal whitish streaks. Etytra : 

 central apical area and the adjoining ante-apical area generally black or pitchy- 

 brown 1. CKOCEA, H.-Sch., = (attenuatus, Marj^hall). 



Elytra not lanceolate, pale testaceous ; nerves almost white. 



Crown with a whitish line down each side of the centre. Pronotum with five, 

 scutellum with three, whitish longitudinal streaks. Elytra — clavus with a 

 black spot at the apex of the central nerve. Corium : apex of the discoidal 

 area and base of the adjoining ante-apical area each with a pitchy-brown or 

 blackish spot ; all the longitudinal nerves, more or less in different individuals, 

 very finely and irregularly margined with pitchy-brown ; central apical area 

 black or pitchy-brown 2. ATTENUATA, Germ., ^ frupicapra, Marshall). 



Very closely allied to the foregoing species, from which it mav 

 at once be separated by the difference in the shape of the elytra and 

 the black spot in the clavus. 



Entirely pale testaceous, and lliickly covered with minute red spots or atoms.
