TOMOCERUS FLAVESCENS TuUberg, var. SEPARATDS, new variety. 

 Plate 40, figs. 1, 2. 



This tridentate variety, already referred to, is well established in 

 this country, and to distinguish it from the typical bidentate form 

 which is common in Europe but rare here, I have been using the 

 varietal name separatus.
