warrant a generic separation in my opinion. It is no un- 

 common thing to find the apical veins differing on each tegmen 

 of a specimen. 



The group of genera to which this genus belongs forms a 

 distinct division of the Cixiidae and could form a subfamily, 

 Meenoplinae. The following nine genera, perhaps with some 

 others, would come into the subfamily: Mecnophis Fieb., 

 Anignis Stal, Nisia Mel., Phaconenra Kirk., Suva Kirk., 

 Eponisia Alats., Paranisia Mats., Inxwula Dist., Paramgrus 

 Bergr. 



Dr. E. Bergroth * has recently written on this group and 

 it is hoped that in the near future he will give us a critical 

 survey of the genera composing it. 



My interpretation of the venation of some of these genera 

 is shown in figures 2 and 3. In A', atrovcnosns ( Leth. ) from 

 Ceylon M2 is missing, ]\r3 and Cul are fused for some 

 distance. Cula is strongly angled near the base and there are 

 two cross-veins, one of which is diagonal. M. albosignatiis 

 Fieb. appears to be similar but for the presence of M2. The 

 first claval and the Sc -}- R are granulate. Paranisia is similar 

 to Nisia in venation and Eponisia- to Meenoplus. Suva differs 

 from Meenoplus in having junction of M3 and Cul nearer 

 the base of the former. Phaconenra agrees with Suva with 

 the exception that M3 and Cul remain together to the margin 

 of tegmen in the type species, but in P. laratica Muir they part 

 company before the apex. In some specimens, including the 

 type of this last species, there are three apical veins to the 

 radius. It is to be hoped that the tracheation of these tegmina 

 will be worked out in the nymph. 



Meenoplus langlei sp. n. Fig. 3, 3a. 



Male. Length 1.7 mm. ; tegmen 3.4 mm. M2 present, Cul touching 

 M3 at its base then free, one cross vein between Cul and Cula, 

 granulate along Sc + R and Al (first claval), Al and A2 meeting near 

 apex of clavus. Anal segment short, curved, apex produced into two 

 rounded processes ; aedeagus fairly long, curved ; genital styles long, 

 thin, curved inward, their apices meeting on middle line, apices slightly
