C; one in the pterostigmatic space; one between I?] and ]!..■; 

 one hot ween R.. and Pt 4 , closing the radial cell distally; one from 

 R4-I-5 toMi_o: one from R 5 to M } ; a short one connecting Rs with 

 M, quite close to the origin of the former; one between M 2 and 

 M 3 , closing the median cell distally; one from near the origin of 

 M 4 to Cu|, with a second somewhat distad from it; an oblique 

 one (possibly a branch veinlet) from ]A to Cu„; and three be- 

 tween lAand 2 A. The two oblique veins running from Cuj 

 downwards are very strongly marked, and quite different from 

 the other cross-veins; so that I have little doubt that they repre- 

 sent true branches of this vein. 



Type, Specimen No. 148a. (Coll. Queensland Geological 

 Survey). 



Horizon : Upper Triassic, Ipswich, Q. 



Genus Neuropsyche, n.g. (Text- fig. 26). 

 Characters of forewing : — A moderate-sized wing with narrow 

 costal area and very narrow, elongated radial cell; pterostigma 

 very long, without any veinlets. Numerous veinlets in costal 

 area, also a number of excess cross-veins scattered irregularly. 

 Sc and R very close together. First and second apical forks 

 very narrow and close together; third and fourth broad and 

 normally placed. Cuj a straight vein without any branches in 

 the preserved part; the same is true of Cu 2 and 1 A. Both radial 

 and median cells closed, the first, second, and fourth apical forks 

 sessile, the third very definitely stalked. 



Genotype, Neuropsyche elongata, n.sp. (Upper Triassic, 

 Ipswich, Q.). 



Evidently closely allied to Mesopsyche from the same horizon. 

 It differs from the latter genus in lacking the subdivision of 

 the second apical fork into three separate cells, but possesses 

 instead two cross-veins in the first apical fork. In Mesopsyche 

 the costal area is not crossed by numerous veinlets, nor is the 

 third apical fork stalked, but arises exactly from the upper distal 

 angle of the median cell. Mesopsyche also lacks the excess cross- 

 veins which are so conspicuous in the new genus.
