Front of head moderately produced, with the sulcus distinct and the sides 

 nearly parallel, not expanding below the middle as in minor. Head broader 

 across the eyes than the front margin of the pronotum ; sides of the pronotum 

 nearly parallel until just before the posterior angles when the pronotum is 

 suddenly widened at the collar. Body very hairy, the hairs on the head and 

 pronotum darker than those on the rest of the body, especially on the under 

 side, where they are almost white. Fore wings with the front margin evenly 

 but considerably curved ; the wings themselves are broader across the middle 

 than in aperta. Uncus when viewed from above broadly lanceolate and sub- 

 acute at ape.x, its width about half the length; seen in profile when raised 

 above the valve it resembles the upturned head of a broad-headed snake. In 

 the female the notch in the last ventral segment \'-shaped.
