present in the Upper Triassie fauna of Ipswich. The more primitive condition 

 of the fossil wing, compared with recent forms, and especially noticeable in the 

 less rounded apex, less expanded costal area, and absence of any definite or 

 complete gradate series of cross-veins, makes it necessary to place Triassopsy chops 

 by itself in a new subfamily Triassopsycbopinae, which may possibly also in- 

 clude the genus Archepsychops, when more of the venation of that genus is 

 made known. 



Triassopsychops superba, n.sp. (Plate lii., fig. 32; Text-fig. 89.) 



Greatest length of fragment (obliquely along lower branches of Rs), 29 mm., 

 representing a total length of 32 mm. Greatest breadth of fragment, 22 mm., 

 representing a true greatest breadth of the complete wing, nea» tornus, of about 

 23.5 mm. The fossil is beautifully preserved, but the apical portion of the wing

is missing, and there are also irreg-nlar breaks along the costal and posterior 

 margins. The more important details of venation have been included in the 

 generic definition; the lesser details of the branching of the veins may be 

 gathered from Plate lii., fig. 32. Text-fig. 89 shows a restoration of the com- 

 plete wing, based on the photograph shown in the Plate.

Order COLEOPTEEA. 



The numerous specimens belonging to this Order, chiefly separate elytra, 

 but some few showing the body of the insect with the wings in situ, are being 

 worked up by Mr. Dunstan, and will be dealt with in a separate part. There 

 is, however, one specimen of great interest which may be dealt with here, since
