2. kochelci. 



The 7th segment (female) triangularly (sides somewhat round- 

 ed) produced, the 8th segment attaining laterally about half the 

 length of the pygophor, which has sparse dark hairs along by 

 the ovipositor and at the apex, and very slightly exceeds the 

 ovipositor in length. 



5 and 9. albotnargiitata. 



Tcttigonia alboiiian^iiiata Signoret 1853 A. S. E. France (3) I, 



347, PI. X, f. 4. 



Tcttigonia pcfliiiioliia Kirkaldy 1906 Bull. Ent. H. S. P. A., J.

At the time of writing my description, Signqret's 'Revue' was 

 unpurchasable, and I did not imagine that this species would 

 be described as 'alboniarginata ;' I have since been able to ac- 

 quire, for the Station, Signoret's work and to identify Signoret's 

 species. The colour of the tegmina, as indeed Signoret figures 

 them, is dark metallic green, not plumbeous-black, as he writes. 

 The species was found by Koebele on Sacclianiiii otticiiiannii. 



7. cocnilcsccns. 



For Signoret's reference, read: cocnilcsccns Sign.. 1853 A. S. 

 E. France, (3), I, 672, PI. XXI, f. 16. 



The vertex is subangulate, and the species is probably not a 

 true Tcttigonia. It is not coerulescent. 



The genera of this tribe may be temporarily disj^osed as fol- 

 ic jws : 



1 jnga porrect, straight or slightly deflexed at the ixpcx, dis- 

 tinctly interrupting the lateral curve of the vertex; fore 



" tibiae distinctly sulcate or Hat, sometimes dilated (2) 



1.') Jnga suddenly deflexed or noticeably curved from the 

 base, never interrupting the lateral curve of the vertex ; 

 fore tibiae subcylindric (rarely otherwise) (26) 



2 Pronotum distinctly sexangular (or more), lateral angles 

 distinct; tegmina com])letelv covering the sides of the 

 abdomen (3) 



2a Pronotum transverse, r|uadrangular ; rarely fet^bly hex- 

 angular (in which case the lateral angels are rotundate) ; 

 tegmina often exposing the sides of the abdomen (8) 



3 Pronotum normal; head not shorter than the pronotum. (4)
