Genus ^Iesopsyche, n.g. (Text-fig. 2, and Plate vii., fig.l). 



To tlie characters of the family, as given above, we add the 

 following generic characters : — Two costal cross-veins preserved 

 (probably three or more in complete wing). 8c and K run 

 parallel and very close together. Pterostigmatic region long 

 and narrow, the proximal cross-vein descending oV)liquely from 

 Sc at its distal end. Rj joined to Kg by a single backwardly 



Text-tig. -2.

For 



slanting cross-vein above Af.l. Discoidal cell (dc) elongated, 

 hexagonal, with Af.l and Af.2 both sessile upon it. Beyond 

 distal side of dc, an extra cross-vein connects Kg with R4. In 

 Af.2, three separate cells (Text-fig.2, /^c^c) are formed by means 

 of two connecting cross-veins and weak zig-zaggingof K4 and Kg. 

 Wing-point (6!;>) placed in Af.2 not far from the forking of K4 

 from Rg. 8ubdiscoidal cell {sdc) elongated, hexagonal. Median 

 cell (mc) an irregular pentagon, with Af.4 strongly sessile upon 

 it, Af.3 just arising from its upper distal angle. Thyridium (t) 

 placed directly under the main forking of Rs. Thyridium-cell (tg) 

 absent. Cu apparently fused with M basally, aij' placed well 

 basad (under second costal cross-vein) and consequently Af.5 of 

 great lengtli. 



So much of this wing is preserved, with the details of venatioii 

 beautifully clear, that there is no difficulty in restoring it to
