ORTHOPTERA— BLATTARI^. 217 



ZETOBORA Burmeister. 



This genus has not before been found fossil, and the species at hand in 

 some particulars more nearly resembles a Blabera ; but its size accords so 

 much better with the species of this genus that it would seem more properly- 

 placed here. Both Zetobora and Blabera are American types and charac- 

 teristic of the warmer regions. 



Zetobora brunneei. 

 PI. 17, Fig. 12. 



A species is indicated about the size of Z. monastica Sauss. It differs 

 from the ordinary forms of Zetobora in the regular form of its pronotum, 

 which resembles that of a Blabera, and is scarcely broader behind than in 

 front, very broadly rounded in front, rounded and not angulate laterally, and 

 a little less than half as broad again as long ; it is narrowly and delicately 

 marginate but nowhere distinctly reflexed, perfectly smooth, and completely 

 covers the orbicular head ; it is light colored but edged narrowly with black. 

 The tegmina are thin and provided with closely approximate multitudinous 

 dark veins ; their exact length can not be determined. The legs are moder- 

 ately slender and show a few signs of delicate spines in such a way as to 

 indicate that others not seen existed, and therefore nothing can be said of 

 them. 



Length of body, 17'"'"; of pronotum, 4.6'"'"; breadth of same, G""""; 

 length of tegmina, 20"'°'?; of middle femora, S""". 



Named for the distinguished orthopterologist. Dr. Carl Brunner von 

 Wattenwyl, of Vienna.

HOMCEOGAMIA Burm. 



A single fossil species is referred here, and it is interesting to find that 

 one of the few species described from the European Tertiaries has been re- 

 ferred by Heer to Heterogamia, a name then used to include both Poly- 

 phaga and Homoeogamia. The species of Homoeogamia are few in number 

 and found only in the warmer parts of America.
