This species somewhat resembles T. viorio and grandis, 

 but is much more slender and easily recognized bj^ the whit- 

 ish antennae. 



Distribidion. — This species ranges from Costa Rica to 

 southern Brazil; it has been reported from Cache, Costa 

 Rica. Szepligeti's specimen came from Marcapata, Peru, 

 and I have before me specimens from San Carlos, Costa 

 Rica, and Rio Grande do Sul, Brazil
