is strong evidence that we have to deal with a hind wing. The absence of a de- 

 finite elaviis points in the same direction. 



Specific characters in the venation are the positions of the cross-veins: two, 

 close together, connec^t Ri with the costal margin ; a curved cross-vein connects 

 Eg+swith R4, and, just beyond it, a straiglit one connects R4 with Ri; another 

 cross-vein desc«nds from the fork of R4^5 on to Mi; a short curved cro.ss-vein 

 bridges the fork between Mi and M2, and, almost exactly below it, a straight 

 cross-vein runs from M2 to M3^4. This latter vein is connected with Cuu, by 

 two straight cross-veins, the more distal of which, placed slightly obliquely, fall^ 

 directly on to the fork of Cuu; just before the middle of its length, Cuit sends 

 a straight cross-vein to Cu2. 



The peculiar formation of vein 2A is very noticeable. Probably owing to 

 an overfolding of the weak membrane, this vein appears to cross lA at about 

 the middle of its length, and then begins to give off a series of short, irregular 

 •^tump-veins which (|uickly fade away into the membi'ane without joining up any- 

 wliere or reaching tlie wing margin. Possibly these are the last remnants of a 

 weak archedictyon. 



The missing parts of the wing are : the basal half of the costal margin, a 

 small piece cut out of the middle of Ri, just distad from the free end of Sc, 

 most of the basal half of M, almost the whole of Cu2, and a naiTow, irregular 

 portion of the wing along the posterior margin, from just before the end of lA 

 right round to the apex.

A monotypic family, with characters as given for the genus Lophicneura 

 below. 



Genus L o P H 1 o x k u r a, n.g. ( Plate xxxv., fig. 2 ; Text-fig. 3. ) 



Fore wing: Size very small, shape elongate oval, about three times as 

 long as broad. R and Cui forming two high, sharj) ridge-veins, strongly convex, 

 nud mucli stouter than the other veins, which are all flat and weakly formed. Sc 

 short, ending on costal margin at about one-tliird from base. R arising from 

 middle of base, and having the i)a.sal portions of M and Cui fused with it ; Ri 

 nmning nearly straiglit, obliquely upwards, to end on the costa about three- 

 fifths from base; Sc and Ri are rouglily )>arallel. Rs a weak vein, arising 

 from R at about one-sixth from base, and running in a gentle double-curve to 

 beyond the level of the end of Ri, where it forks widely ; the upper fork, R2+3, 

 runs parallel to Ri to the costa; the lower fork, R^^s, runs obliquely down- 

 wards to end up at apex. M arises from R a little before origin of Rs, and 

 runs below it in a single concave curve nearly to the level of the end of Ri, 

 when it forks similarly to Rs; the upper fork. Mi ^2, arches upwards, and then 

 curves to ran below and parallel to Ri+jto a point well below apex; the lower 

 fork, M:;: 4, makes a very weak double-curve, and ends on the posterior margin 

 a little beyond the level of the fork of Rs. Cui arises from R a little before 

 M, and runs as a high ridge to al)out half-way along the wing; this part of it 

 makes a single continuous curve below and sub-parallel to M. At the point
