Ipsviciopsis magna^ n.sp. (Text-fig. 86.) 

 This species is represented by a fragment of a right teg-men, reverse im- 

 pression, measuring 10 mm. in length, and obviously belonging to a large teg- 

 men, probably about 26 mm. in total length. It is very much cracked and

broken transversely, possibly owing to its toughness and may have been cracked 

 under pressure. It differs markedly from the previous species in possessing a 

 series of transverse veinlets ranning from Rs across Ri to the eosta. Ri ends 

 up on the fourth of these, which is joined near the costa by the fifth, these two 

 arising one on each side of the strong cross-vein connecting Rs with M. A sixth 

 veinlet is shown distally from Rs to the costal margin. R is also connected 

 more basally with M by a short cross-vein, absent in the previous species; and 

 a small-, cross-vein, obliquely placed, connects Cui with Cu2 at about the same 

 level. Clavus and distal portion of the wing missing, as well as the extreme 

 base.

Family DUNSTANIIDAE. 



Specimen 119a is a hemelytron belonging to this family, probably to 

 Dunstaniopsis triassica Till., but not well enough preserved for accurate deter- 

 mination. The greater portion of the eorium is visible, with tlie stems and 

 branches of M and Cu, but all the margins are destroyed. Tlie clavus and mem- 

 brane are mostly obliterated.
