Type. Incomplete wing; British Museum (Brodie Collection, no. I. 3896).

FIG. 15. Brodia, priscotincta, Scudder; diagram of a complete left wing showing position of tubercles 

 and character of neuration, natural size. Middle Coal Measures ; Dudley, Staffordshire. 



Specific Characters. Outer margin of wing spinulose, almost straight, or feebly 

 convex at the most. Subcosta remote from margin at base, and extending beyond 

 the middle of the wing, joining neither to the costa nor to the radius. Radius a 

 strong vein, and spinulose. Radial sector arising in the first half of the wing, and 

 giving off four branches. Median with two forward branches. Cubitus a single 

 vein. Anal veins two. Inner margin strongly convex. 



Description. The Geological Department of the British Museum possesses no 

 less than eleven examples of this species in addition to the type, while two more 

 are in the Geological Collection of Birmingham University, one being in the Beale 

 Collection, and the other presented by Dr. Blake. The British Museum specimens 

 are registered as follows: I. 1557, I. 1567, I. 3879, I. 3896, In. 18431, all from 

 Coseley; I. 2961, In. 18433, In. 18434, all from Tipton; In. 18429 from Sedgeley; 

 and In. 18430, I. 5866, I. 2962, and In. 18432. The following description and 

 remarks are based on a study of all these specimens. 



The longest wing I have seen measures 58 mm. in length, and we are not likely
