elongate, second short, almost globose ; first few flagellar joints 

 elliptic or ovate, progressively shortening and narrowing, the last 

 few joints (the terminal four in T. fastidiosa) linear (PI. vi., 

 fig. 27, $ antennse of T. fastidiosa). Collare inconspicuous. 

 Thorax elongate-ovate ; scutellum small ; metanotum convex. 

 Abdomen rather slender, at least twice the length of the thorax ; 

 (J forceps not incrassate, of simple structure (PI. vi., fig. 26, 

 forceps of T. fastidiosa) ; 2 ovipositor with rather small straight 

 pointed valves. Legs vexy long and slender ; all tibite with a pair 

 of small spurs ; tarsi twice the length of tibiae, the metatarsal joint 

 very long. Wings longer than the abdomen. Discal cell present. 



According to the generic description of Brachypremna, which 

 I understand to agree in the main with this genus (of which I 

 have not seen the original diagnosis), one of the most striking 

 features is the perpendicular position of the anterior branch of 

 the second longitudinal vein, which is inserted at the point where 

 the first vein incurves into the second, and looks like a cross- 

 vein ; in T. fastidiosa, however, this branch is obliquely situated.

 indistinct) narrow stripes extending to suture ; intermediate stripes 

 confiuent posteriorly ; lateral ones short, rather broader and less
