anal area with only vestiges of anal veins. The veins and inter- 

 calated ridges are well preserved, and the form of branching of 

 R, M, and Cu is not unlike that of S. reticulata, n.sp. But M 

 had certainly less than seven branches, while Cu, which is com- 

 pletely preserved in this fossil, shows only six.

Samaroblatta blabelloides, n.sp. (Text-fig. 37). 



A well preserved fragment of a left tegmen, with the apical 

 third missing, broken off along a very irregular line. There are 

 also small portions missing from the anal area and extreme base. 



Greatest length of fragment, 9-3 mm., indicating a tegmen of 

 total length 13 mm. Greatest breadth, 5 mm., being the total 

 breadth of the tegmen. 



Costal area fairly wide, sharply pointed at apex, 6 mm in 

 length from base to apex; bounded distally by the straight vein 

 Sc, from which a less distinct branch comes off within the area; 

 slight signs of a series of oblique costal veinlets towards the 

 base. Sc, R and its branches consisting of very thick veins; M 

 and Cu only moderate. Primary branches of R seven, excluding 

 the forked end of the main stem; the first four straight, simple
