is next related to the Ephemerina. The parts of the mouth 

 have nothing of the Hemiptera about them and they are even 

 more related to 

 the Diptera." 

 While we would

 judgment of 

 these distin-

 have actually 

 studied the fos-

 judging from 

 Dohrn' s draw-

 refer the insect

ters we are strongly reminded of certain more abnormal genera 

 of Hemerobidce and the Panorpidce. The wings while 

 closely resembling the Ephemerids, as Dr. Hagen has sug- 

 gested to us, also, in our opinion, recall those of an African 

 species of Palpares, and of the fore wings of Nemoptera, and 

 the antennae and beak-like mouth-parts seem analogous to 

 those of Pauorpa and Boreus.*

*Erichsou and Siebold have grouped the Termiticlce, Psocidce, Embidee, . 

 Ep h e in e r i d (e and Libellulid <x under the name of " false " Neuroptera, and con- 

 sidered them as Orthoptera, restricting the Neuroptera to the Sialidce, Ilemero- 

 lidce, Panorpidce and Pliry ganeid(e,nn(\ this classification has been adopted 

 by most continental entomologists. Now while believing in the unity of the Neu- 

 ropterous type, and that the so called "false" Neuroptera (especially the May-flies 

 and the dragon-flies) are really the most typical of the suborder, being the most 

 unlike other insects, do not we have many characters in these palaeozoic net- 

 veined insects, which unite more intimately the so called false and true Neurop- 

 ters ? We would not forget the analogies shown in these fossil net-veiued insects
