place this interesting fossil in the genus Inoeellia, this course -would 

 be suggested chiefly by the presence of the distal subcostal cross-vein. 

 In any event, it should be noted that here characters of both recent 

 raphidian genera are mingled. This fact will probably warrant the 

 establishment of a new genus ; especially as the fossil form described 

 by Seudder cannot be admitted in the recent genei^a. 



' Baphidia ' erigena, Hazen, from the lower Oligocene of Europe 

 (amber), is a tiypical Inoeellia. On the other hand, it seems to me 

 that 'Inoeellia' veterana, Seudder, from the Miocene of Florissant, 

 represents a distinct genus, which is characterized by the much 

 greater development and ramification of the sector radii, by the 

 much more numerous cross-veins, and consequently by the far 

 greater number of cells; hence, for this genus I propose the name 

 Dictyoraphidia. 'Inoeellia' iumulaia, Seudder, from Florissant, 

 appears to be most closely allied to the new form above described; 

 but is distinguished by a somewhat more profuse branching of the 

 sector and by three cells between the riadius and sector. ' Baphidia ? ' 

 tranquilla, Seudder, from Florissant, may also be a form most nearly 

 related to iumulaia; for it distinctly shows the distal cross-vein in 

 the subcostal areia, and likewise three cells anterior to the sector. 



Eegarding 'Inoeellia' somnolenia, Seudder, from Florissant, I 

 can express no opinion without having seen the original; for in the 

 drawing the venation of the superimposed wing is not sharply de- 

 fined. A definite opinion concerning the unfigured 'Inoeellia' 

 eventa, Seudder, from Florissiant, must likewise be withheld; yet 

 from Scudder's statements relative to its great similarity to iumu- 

 laia, Seudder, one may conclude that it also belongs to the same 

 group as the latter form. 



Should these views be confirmed, it will probably become neces- 

 sary to establish new genera for these complex extinct specie3, which 

 are intermediate between the two recent genera ; hence, for the form 

 above described I propose the name Archiinocellia, and for the others 

 mentioned I suggest the name Archiraphidia. 



In addition to the foregoing forms and a larva from the amber, 

 only one other has become known — Megaraphidia elegans, Cockerel!, 

 from Florissant, which is undoubtedly a well-founded genus. Present 

 knowledge of the fossil raphidians may, therefore, be expressed as 

 follows: — •■
