The connection between nymphs and imagoes appears to me in no 

 case proved. Moreover we have as yet far too few stages to enable us 

 to determine the genus of nymphs, t)ecaiise hitherto a relatively very 

 small number of such fossils have been found and described. I there- 

 fore consider it advisable to cite here all the previously observed forms 

 and leave their interpretation to the future.

This fossil reallv looks very similar to an e^^^ sack. Moreover, 

 such forms have already been found in Europe.

Even though the blattoid nature of this fossil can not be questioned, 

 it still seems to me unproved that the specimen pertains to a mylacrid
