BOTANY AND PALAEONTOLOGY 



23. Blattina venusta, Spec. nov. (PL 5, fig. 11.) It is one of the most 

 interesting remains found in the coal formations of America. It shows 

 the upper wing, partly broken, of an insect related to the genus Blatta, of 

 of which our common cockroach (Blatta Americana) is a species. Prof. 

 Germar has already figured and described in Germany some of these 

 always very rare remains ; but our species differs much from all those which 

 have been found in the coal of Europe. The wing represented, fig. 12, 

 belongs to the still living species, Blatta Madera? ; it is copied from the 

 figure of M. Germar, and shows the greatest likeness to ours. Its nervules 

 are also, though more remotely, marked by transverse reticulations. This 

 fossil wing found in the shales of Frog bayou, has apparently its extremity 

 broken out, and its general outline is likely the same as that of fig. 12. 

 The presence, in the coal-measures, of insects of which the identical type 

 has been preserved till our epoch, is a remarkable phenomenon of natural 

 history, and could not be but carefully recorded.
