2. T. longipennis, sp. nov. 



A typical Tetrix having long wings and subulate pronotal process. 

 Stature small, body somewhat scabrous-tuberculate in the female, 

 smoother granulate in the male ; colour variable, more often fuscous, 

 sometimes greyish or testaceous or dark covered with light granula- 

 tions, disc not maculate, variably marked behind, hind tibia? 

 infuscated more often lighter behind the knees and distal third part. 

 Vertex wider than one of the rather small eyes, somewhat flattened, 

 front margin barely advanced beyond the eyes, rounded or convex, 

 median carina little produced anteriorly ; frontal costa slightly 

 sinuate opposite the eyes, lightly convex between the antenna ; in 

 profile the vertex and facial costa distinctly advanced beyond the 

 eyes. Pronotum often scabrous, anteriorly truncate, posteriorly 

 subulate, extended beyond the femoral apices ; dorsum transversely 

 tectiform, subfossulate at base of process ; median carina compressed 

 subarcuate anteriorly often undulate in the female, nearly entire in 

 the male ; humeral angles carinate ; prozonal carinae parallel, 

 slightly ex^iressed ; lateral lobes posteriorly bisinuate, the posterior 

 angles rounded or hebetate. Elytra oval, rather large, apices some- 

 what widely rounded ; wings fully explicate extended beyond the 

 apex of pronotal -process. First articles of posterior tarsi twice the 

 length of the third, the pul villi unequal, the third equal in length to 

 the first and second combined, straight below, the first pulvilli small, 

 acute ; anterior femora elongate margins entire j middle femora com- 

 pressed, in the female the margins undulate, in the male the femora 

 ampliate, margins entire ; posterior femora elongate.

 8*5-9'5 mm.; posterior femora 4*5-5 mm.
