58 Dr. H. Woodward — British Carboniferous Coclcroaches. 



appears to occupy tbe largest area, and gives off very numerous, 

 branches which fork near the margin of the w^ing. The venation is. 

 most distinct upon the under wings, but these, although the most 

 interesting, cannot be seen so fully as the upper ones, being partly 

 covered by the latter. 



Detached limh. — Near the extremity of the abdomen of Fig. 3 

 lie the detached tibia and tarsus of one of the limbs. It can be just 

 made out with its numerous distal segments. 



There can, I think, be no doubt that these two specimens from the 

 Dudley Coal-field, which, in the narrow elongated form of the 

 abdominal somites, present so remarkable a divergence from the 

 living Cockroaches, are very closely related to (though probably not 

 specifically identical with) Dr. F. Goldenberg's Blattina insignis, 

 figured and described by him in his work, entitled " Fauna Sarepon- 

 tana Fossilis " (4to, 1873, I. Heft, taf. ii. fig. 14, p. 17), from the 

 Coal-measures of the Skalley Shaft, Saarbriick. 



Dr. Groldenberg's Blattina insignis has the same general form of 

 the pronotum and wings, and is characterized by the same slender 

 abdominal somites, but it is very much, smaller in size than our 

 English specimens ; and if reliance may be placed upon the sketch 

 of the venation of one of its wings (sent by Goldenberg to Scudder, 

 and reproduced by the latter author in his Memoir, 1879, op. cit. 

 pi. iv. fig, 9), the details of the wings do not agree; but this, like- 

 the outline given of the wing itself, may very well be subject to 

 revision. 



Mr. S. H. Scudder has arranged all his American Blattince and 

 also all the old-world forms under new genera, and has placed Golden- 

 berg's iJZaiima insignis with a note of interrogation uudev Etohlattina. 

 This seems waste of energy merely to remove a species from one 

 genus to place it doubtfiiUy in another. Now that its characters are 

 more fully revealed to us, it is apparent that its place is not in 

 Etohlattina, but in a distinct genus which might be appropriately 

 designated Zeptohlattina, for the reason sufficiently apparent in the 

 foregoing remarks. 



Leptohlattina. exilis, like Etohlattina Jolinsoni, was obtained by the 

 late Mr. Henr}^ Johnson, F.G.S., from the clay-ironstone of Coseley, 

 near Dudley, and the specimens are now, with the rest of the treasures 

 of the Johnson Collection, preserved in the British Museum of 

 Natural History, Cromwell Eoad, London, S.W.
