As may be seen from the above description, T, con- 

 spiciia is closely allied to T. Alonteironis, from which, 

 however, it can be easily distinguished, not only by the 

 prominent spot on the tegmina and the absence of the 

 spots on the lateral abdominal edges below, but also by the 

 following structural characters. The pronotum is broader 

 and more convex, and the frontal borders of the scutellum 

 very much more raised and distinct. The scidpture of 

 the upper surface of the head is also different.
