484 PROCEEDINOS OF THE NATIONAL MUSEUM. vol.49. 



Venation of hind wings ordinary for the group. Epinotum 

 rounded; petiole formed as in modern Dolichoderus, as also the 

 gaster. 



Ohgocene at Gurnet Bay (Brodie). Lacoe Coll. 7578, and its 

 reverse 7641 (type). I also refer here 7584, although the first dis- 

 coidal cell is longer. This specimen is preserved as a lateral section, 

 showing the body cavities. The petiole, here seen in lateral profile, 

 agrees with Dolichoderus. A very similar species is Dolichoderus 

 oUiteratus (Hypoclinea oUiterata Scudder) from the Tertiary at 

 Quesnel, British Columbia.

DOLICHODERUS ANGLICUS, new species. 

 Plate 65, fig. 8. 



Femdle(f). — Anterior wing 5 mm. long to base of stigma, total 

 length probably about 8 mm.; venation differing from that of 

 D. hritannicus as follows: Second submarginal cell petiolate above, 

 not reaching marginal, and also failing to reach first discoidal. The 

 following measurements are in ix: Transversomedial to basal corner 

 of first discoidal cell, 640; length of first discoidal, 1,120; length of 

 second submarginal, 1,440. 



Ohgocene at Gurnet Bay (Brodie). Lacoe Coll. 7610. This is 

 considerably larger than the last and differs in the venation, so it 

 probably represents a distinct species.

DOLICHODERUS OVIGERUS, new species. 

 Plate 65, fig. 9. 



Female. — Length about 6.75 mm.; anterior wing about 5.25 mm., 

 hyahne, with ferruginous nervures. Structure, including petiole, 

 essentially as in D. hritannicus, from which it may not be distinct, 

 but the second submarginal cell goes beyond the base of the marginal, 

 and fails to reach the first discoidah The following measurements 

 are in ix: Transversomedial to basal corner of first discoidal cell, 480; 

 basal nervure on first discoidal, 464; basal nervure on first submargi- 

 nal, 208; first submarginal on first discoidal, 640; base of second 

 submarginal to apical corner of discoidal, 144; length of second sub- 

 marginal, 928; width of second submarginal at apex, 320. Anterior 

 femur about 1,200 n long; hind femur long and slender, 1,920 a» 

 long and 272 broad. The abdomen contains an eggshell, 432 /x long, 

 so perfectly preserved that I wondered whether it could have come 

 from some modern insect; but it appears to be part of the fossil, 

 along with numerous indications of the internal tissues.
