in addition to the transverse carina, an equally distinct carina going down each side 

 from a transverse keel at the extreme base ; by the depression in the middle of the 

 metanotum at the base being longer and broader ; by the scutellum being more gibbous ; 

 by the petiole having distinct tubercles in the centre towards the middle, there being 

 also a longitudinal depression in the middle above. The wings are, as in T. tolteca, 

 hyaline,, smoky at the apex, the cloud being darkest. Antennae as long as the body.

 so long as the two following joints united. Sides of the . metanotum obscurely trans- 

 versely striated, the middle transverse keel very distinct. Scutellum carinate at the 

 base. Base of the abdomen semiperpendicular, hollow in the centre ; sides of the 

 segments depressed in the centre above. Areolet 4-angled, angled where the recurrent
