The type of this species was received too late for its inclusion 

 in the synoptical table. It belongs to the group of brown- 

 faced species and really comes nearest to verecundus from which 

 it differs at once by its much larger size and the still longer 

 vertex. It has somewhat the aspect of the female oregonensis 

 but the vertex is longer, broader, and more rounded at tip. 

 The elytral reticulations and areolar spots are finer but dis- 

 tinct ; the general color is more cinereous than fulvous ; the front 

 is fuscous-brown irrorated with paler and becomes darker or 

 almost piceous at the pointed base below the short but distinct 

 and acutely angled white line, and the lower surface of the body 

 is varied with pale and brown. The last ventral segment of the 

 male is about as long as the third and is broadly subangularly 

 excavated; valve rather short and broadly rounded; plates 

 broad-triangular and shorter than the valve. The pale pro- 

 notal vittae are obvious but not conspicuous and the vertex 

 is blackened on the immediate apex with a white point at tip 

 and a pale marginal mark on either side and another half way 

 to the eye. The unique male type was taken in November at 

 Chapada, Brazil.
