T^YO NEW FOSSIL COCKROACHES FROM THE 

 CARBONIFEROUS OF CAPE BRETON. 



By Saml'el H. S^ctddsr. 



Tlirougli the kindness of Dr. J. W. Dawson, I have been 

 •enabled to study two fossil cockroaches, from the collections made 

 by R. Brown. Esq., F.G.S,, in the carboniferous deposits of the 

 .Sydnej' coal-field, Cape Breton, and placed in Dr. Dawson's, 

 hands for determination of the fossil plants. When more species, 

 and specimens of this ancient group shall have been discovered^ 

 I hope to undertake a revision of the whole, meanwhile describ- 

 ing new forms under the generic name Blatfina, a somewhat 

 heterogeneous group to which most fossil cockroaches have, for 

 convenience' sake, been referred. 



Three fossil cockroaches have already been described from the 

 carboniferous formations of America : Blattmi. venusta, Lesq., 

 from Arkansas, ArchimiiJacris acadicus, Scudd., from Pictou, 

 N.S., and Mylacris antJiracophilus, Scudd., from Illinois. With 

 the exception of the last, where the pronotum is also preserved, 

 each of these fossils is represented by a single upper wing. The 

 two additional species now described are also similarly repre- 

 sen ted ; thus every specimen yet dis3overed in America is 

 referable to a distinct species.
