130 S. H. SCUDDER ON PALAEOZOIC COCKROACHES. 



It does not, however, agree al all with the structure of the hind wings of palaeozoic cock- 

 roaches already known. 



Only after the printing of most of this paper have we had access to a paper hy Dr. 

 C. J. Andra (Eine Alge und eine Insectenfliigel aus den Steinkohlenformation Belgiens. 

 <Sitzungsb. niederrhein. Gesellsch. Bonn, 1870, 27-28) in which mention is made of the 

 occurrence of the wing of a cockroach in the coal formation of Belgium. The author 

 merely states that an elliptical fragment, representing the margin of a wing, was found, 

 the distribution of the veins in which substantially agreed with that of "Blattina." 



Explanation of the Plates. 



PLATE II. 



All the figures on this plate and the two following are camera lucida copies from other authors; the scale 

 is altered where necessary, so as to be uniformly about two diameters above the natural size; the marks out- 

 side the winp represent, the limits of the several areas. They all represent European insects. Drawn by the 

 author.

 however, is represented as broader than it should be, and the restored outline is probably too contracted.
