like. Mouth opening rather large; proboscis small; palpi not broad. 

 Dorsum of thorax with two pale lateral stripes, not always distinct, 

 running from scutellum to suture; the disk of thorax sometimes pale, 

 or of the color of ivory; anterior pair of dorsal bristles considerably 

 behind the suture. Scutellum with four bristles. Metathorax in the 

 middle with a round dark spot. A very distinct black spot occurs 

 just behind the root of the wing. Abdomen pilose, with bristle-like 

 hairs on hind borders of last segment. Ovipositor broad, flat, as 

 long as last two segments of abdomen. Legs stout, front femora 

 with bristles above and below; hind femora with sparse bristles 

 below and those above confined to the distal end. Wings large 

 with a banded pattern, much more diffuse than in allied species; 

 picture yellowish in color, consisting of (i) an indistinct band, 

 beginning at the humeral cross vein; (2) a band starting from the 

 costa at the middle of the second costal cell, traversing the cross 

 veins which limit the posterior basal cells, and uniting with (3) a 

 third band, near the end of the sixth vein; the third band proceeds 

 perpendicularly to the costa and fills out the stigmatical cell; (4) a 

 small band arising upon the costa, bisecting the marginal cell and 

 joining third band near small cross vein; (5) the main band of the 

 wing crosses it over the posterior cross vein and is connected with 

 (6) the sixth bantl which fills out the tip of the wing along the costa 

 to a little past the end of the fourth vein. The fifth band throws out 

 three branches distally, the first connecting with the second on the 

 fourth vein, enclosing a clear space; the second and third (sometimes 

 absent) reach the margin of the wing in the second posterior cell. 

 Third vein well bristled; lower corner of anal cell produced. 



Length of male, 7 mm.; female, 9.5 mm. 



Fifteen specimens, Kansas (Williston and F. H. Snow;, State of 

 Washington (Morrison). 



This species is a true (Edicarcna which differs from Spilographa 

 chiefly in the tumidity of the head, and the straight course of the 

 third vein. The two species which have been previously assigned to 

 this genus have a much simpler wing pattern than diffusa, greatly 

 resembling Spilograplia electa. Both were described from males and 

 the females have never been described. The females of diffusa pre- 

 sent the character of a broad, flat ovipositor, differing strongly from 

 the short, thick, not at all flattened borer of S. electa.
