yond the tegmina a distance about equal to the length of the pronotum. 

 Abdominal styles long and tapering, about half the length of the oviposi- 

 tor, the latter being slightly longer than the body, slender, slightly arcu- 

 ate dorsad in the proximal half, the apex armed ventrad with blunt teeth, 

 the immediate apex very sharp ; subgenital plate obtuse-angulate emar- 

 ginate at the apex. Caudal femora slightly less than the body in length, 

 not very robust, the greatest width contained about four times in the 

 length ; caudal tibiae hardly exceeding the femora in length. 



General color wood brown, the limbs slightly tinged with mars brown, 

 the head with cinnamon-rufous, the tegmina with their neuration but 

 little relieved from the base color, and the abdomen and ovipositor near 

 burnt umber in tone. Eyes cinnamon ; antennae of the general color, 

 faintly annulate distad ; angle of the tegmina narrowly lined with pale 

 yellow and this finely interrupted with blackish spots and points ; apex 

 of the ovipositor blackish ; limbs more or less obscurely sprinkled with 

 minute umber spots.

t The horns of the female type are very well marked, but none are present in the male 

 type. As twenty-six specimens of this submenus have been examined, and all possess 

 horns except this male, it seems highly probable that their absence is purely accidental.
