postnodals, triangle with one cross-vein, internal triangle of three cells, three 

 post-triangular rows to the level of the nodus increasing to seven marginal 

 cells, upper sector of the triangle curved strongly forwards without affecting 

 the number of post-triangular rows but merely rendering the cells smaller. 

 Hind wings brown in the subcostal space to the second antenodal, the brown 

 overflowing into the costal and median spaces, which are somewhat clearer, 

 a large brown spot from the submedian vein nearly to the hind margin of the 

 wing and outwards to the level of the triangle, the centers of the cells within 

 this spot clearer, apex brown for a width of three cells, nine antenodals (the 

 last one on the left side of the broken female is not continued to the median 

 vein), nine to ten postnodals, triangle free, two post-triangular rows to the 

 level of the separation of median and principal sectors, increasing to ten to 

 eleven marginal cells. 



Dimensions: Total length 42 (?) mm., abdomen 30 (?) mm. (I have unfor- 

 tunately neglected to make these measurements from the entire female), 

 hind wing 30 mm., pterostigma 4.5 mm.

The shape of the appendages and of the genitalia of the second abdominal 

 segment of the male and of the vulvar lamina of the female is the same as in 

 T. umbrata L. The oldest individuals of both sexes have the body, includ- 

 ing the legs, black, both front and hind wings blackish brown from the base 

 to a little more than half-way from nodus to pterostigma. In younger males, 

 at least, the front wings may be clear from the base almost to the nodus, 

 smoky brown from the nodus half-way to the pterostigma, the hind wings 

 with the basal fourth clear, succeeded by smoky brown to the middle point 

 between nodus and pterostigma. In teneral males and females the colors of 

 the body are like those of teneral umbrata, the wings are usually yellowish 

 from the base to a little more than half-way between nodus and pterostigma. 

 In individuals of all ages, therefore, umbrata is to be distinguished by the 

 transverse band of the wings having its outer margin at the inner end of the 

 pterostigma, while in funerea the outer margin of the yellow or dark color- 

 ing lies only a little beyond the half-way point between nodus and 

 pterostigma.
