branches, and the stroii^'ly devoloped ru])itus gives off al)oat 8 in part 

 eompoimd offshoots ohliciuely back\vai"d. Tlie anal area is defined by 

 an arcuate fold, and contains numerous veins continuing to the poste- 

 rior border. Between many of the principal branches accessory veins 

 iire to be noted.

Family ADIPHLEBID^T], new family. 



In this family I place two forms with highly specialized wings and 

 enlarged, shield-shaped prothorax. The habit of these forms is 

 decidedh' blattid like, but the venation departs so widely from that 

 of all known Paleozoic blattids that it can be hardly possil)le for its 

 derivation to be traced from a l)lattid wing. The branches of the 

 radius, the media, and the cubitus, as well as those of the subcosta, 

 run off almost ray like from the base of the wing, and are separated by 

 numerous intercalar}" veins; the interspaces are bridged over by many 

 cross veins. 



In my opinion, we may be dealing with a highly aberrant side branch 

 of the Protoblattoidea, which probably again disappears in the 

 Paleozoic.

ADIPHLEBIA LONGITUDINALIS (Scudder). 



Termes longitudinals Scudder, Mem. Boston See, III, 1885, p. 850. 

 Goldenbergia longitndinalis JiRo^G^XARr, Bull. Soc. Rouen (8), XXT, 18S5, p. T)!. 



Locality.— Isi'Azon Creek, near Morris, Illinois. Pennsylvanian; 

 Kittanning 'i (Allegheny) stage. 



This form may possibly coincide with Adiplthhin hicoana. The 

 original distinctly shows the form of the thorax and the Avings folded 

 over one another, the neuration of which appears to have great simi- 

 larity with that of the foregoing species. 



Later, Scudder himself recognized that this fossil was not a termite.

Famti.v AN1T1RACOTHREMMID.E, new family. 



I establisl' this family on one of the remarka])le insects described by 

 Scudder, the wings of which essentially differ from those of all other 

 Carboniferous insects hitherto known; its chief relations are neverthe- 

 less still with the ])lattieform series. Tli(> ])()dv of this insect is i-obust.
