nie admissible, from such a specimen, to -establish the hypothesis that 

 the entire Protoblattaria^ had ovipositors and were accordingly derived 

 from locust-like ancestors; for it could not perhaps be shown that the 

 "ovipositor" in question is iiothino- but an excrement. Moreover, in 

 regard to this, let it here be pointed out that in the protoblattoid 

 Euca&nus vniaginale ovipositors are present, which suggests the idea 

 that this larval form, in case it actually possesses an ovipositor, may 

 belong to the Euca'nida\
