Green or testaceous ; thorax with an elevated dorsal line behind, the anterior 

 margin of the deflexed portion white or yellowish, sometimes bright green; 

 elytra horn-coloured, with a yellowish streak on the shoulders ; abdomen 

 with two black streaks towards the sides, and posterior femora with one on 

 the outside at the base ; ovipositor short and much curved. 



This species appears to be very rare in this country. I have 

 hitherto seen, so far as I remember, two examples only, which are in 

 my own collection, and were found in the vicinity of the metropolis 

 in the autumn, I believe at Hampstead.

 totis griseis, femoribus posticis interne et externe vittd nigra. (Long. corp.

 Ac. Kirbii. Dale MS. 



Green or griseous ; thorax with an elevated dorsal line behind, the hinder 

 edge of its deflexed portion alone white; elytra with the anterior and 

 posterior margins bright green, or entirely griseous in the females ; posterior 

 femora with a black streak at the base, both in the outer and inner surfaces, 

 the inner one shortest ; ovipositor of the female rather long and straightish. 



Not uncommon in the New Forest, and occasionally in the vicinity 

 of the metropolis : I have taken it at Coombe and Darenth woods, 

 and also near Ripley, in July and August.

 acuminated in front ; antennae about thrice the length of the body, very 

 slender, with the basal joint very robust, produced within, the second rather 

 smaller, the other joints considerably attenuated ; thorax rounded above, 

 with the sides gradually deflexed ; elytra more or less elongate, nearly or 

 quite as long as the abdomen, ocellated in the males; wings small, or rudi- 

 mentary; abdomen somewhat cylindric, with four very short styles at the 

 apex in the males, and two in the females, the latter sex with a short 

 slightly curved, or lougish and nearly straight ovipositor.
