VOL. 68 TERTIAEY INSECTS FROM SIBERIA COCKERELL 3 



more so than in P. cinerea, etc. • There is an approach to the Floris- 

 sant Miocene P. wlckhmni Cockerell. In the Tertiary rocks at 

 Posiet, Siberia, Doctor Kryshtofovich obtained cases of Phryganea 

 {P. hryshtofovichi Cockerell), about 7 mm. wide, made of pieces of 

 Sequoia langsdorffl spirally arranged exactly as in the living P. 

 grandis. The pieces are about 5 mm. long and 1.2 wide. On the 

 other hand, the cases from the Miocene of Oeningen, which Heer 

 named Pki^ganea aritiqua^ do not belong to this genus. 



Amagupsychinae, new subfamily 



Wings very broad ; anterior wing similar in most respects (in- 

 cluding characteristic region at end of cubitus) to that of Phig- 

 ganea, but possessing a complete median cell, and two simple anals; 

 media four-branched, but the fourth branch arises very obliquely 

 close to the base of the median cell, and after a short distance is con- 

 nected with the cubitus by a transverse cross vein ; thus all five forks 

 are present. 



Type. — Amagu'psyche., new genus. 



This might be regarded as the type of a new family, but the 

 structure so closely simulates Phryganeidae that I believe there is 

 actual affinity, the fossil representing a branch of the phryganeid 

 stem which has not persisted. 



AMAGUPSYCHE, new genus 



Anterior wing broad, mothlike, shaped approximately as in Neuro- 

 ma ruficrus^ not hairy, veins pale-brownish; subcosta apparently 

 quite simple, ending very acutely on margin at about level of end of 

 median cell; radius (RJ stout, simple, not in the least undulate 

 subapically, connected with R, by a transverse cross vein a short 

 distance beyond discoiclal cell, the vein R, bent at the cross vein; 

 discoidal cell large, about as long as its stem, but not nearly so long 

 as the distance from its end to apex of wing; side of discoidal be- 

 tween first and second forks somewhat oblique, face on first fork 

 twice as long as that on second; median cell long-cuneiform, about 

 as long as discoidal, cross vein to radius at a less distance from its 

 end than the length of its apical side; first tAvo branches of media 

 (third fork) separating just before end of median cell; M3 contin- 

 uous to margin in line with lower side of median cell; M4 leaving 

 median cell obli(]uely very neai" its base, and connected Avith cubitus 

 by a cross vein nearly as long as face of discoidal cell on first fork; 

 end of cubitus forming a short triangular fork exactly as in Phry- 

 ganea; first anal ending at base of cubital fork ; second anal quite 

 simple (it is also simple in iT/c/zvY/V?, PalaeolepkloHtoma^ Maniconeu- 

 rodes and Ogmomyla)., ending at same point as end of C\\.,. 



Type. — Amagupi<y('h(' perlata^ new species.
