The synonymy of Typhlocyba Germar tee ree at to these authors, 
stand as follows: Erythroneura Fitch, Idia Fieber, Zygina Fieber, Anomia 
Fieber, Aidola Melichar, Empoa Fitch mii Zyginelia Low. The splitting 
of this unweildy genus becomes, therefore, an obvious desideratum, and 
Typhlocyba (sens. strict. and as by me) the fourth apical vein of 
tegmen curves to the radial pes cad the second apical cell is triangular 
and usually stalked, while in Erythroneura (sens. strict.) the fourth apical 
vein of tegmen runs parallel to the radial margin and ends in the apical 
on the eross-vein. Examination of very large series of New Zealand 
specimens has shown this to be a vertes constant character so far as

this difference more clearly than a printed description. Should further 
study demonstrate instability in this venational character, all the species 
I have described under Erythroneura must be placed in Typhlocyba, which 
will then have the complete synonymy given above. In all the species 
of both genera which I have examined the male genitalia, and especially 
the aedeagus, differ fundamentally, and thus afford a sounder distinc ion 
between the two genera than the venation alone could supply. The figures 
will show this clearly. 
Genus 1. -DrxgaNEURA Hardy. 
An almost cosmopolitan genus. 
Jee maorica n. sp. (Figs. 16-18.) 
9. X, pronotum, and seutellum sulphur-yellow. Tegmina paler. 
Eyes black. Wings hyaline, somewhat opalescent. Underside and legs 
uniform yellow. Oasis black. Tarsi often green. Rostrum tipped with 
crimson. Vertex rather more than twice as wide as medianly long. Fore- 
border rounded. Pronotum T anteriorly ; posterior angles somewhat 
produced but truncate ; posterior border moderately excavated. vecina 
concolorous with rest of body, “seat ovipositor, which is shining br

Female, 3 mm. 
Male unknown. 
This beautiful little species is near to D. flavipennis (Zett.), which it 
resembles also in weed bores sedges in ege. places). It is distinguished 
by the fore-border x, which in our species is rem instead of 
angular, and by the nisi of black же on the hind t
