 reaching the third abdominal segment (rostrum mutilated). 



Tegmina and wings pale hyaline, their apical areas (espe- 

 cially those of tegmina) suffused with bronzy brown.

Hah. Borneo, Elopura {Pryer). Coll. Dist. 



Dunduhia tavoyana, n. sp. 



Above resembling in size, general hue, and markings D. 

 tripuraswa^ Dist., but differing remarkably from that species 

 by the size and shape of the opercula, which have their apices 

 somewhat acutely pointed and reaching the penultimate 

 abdominal segment, their lateral margins being concave near 

 base, convex about centre, and somewhat profoundly concave 

 towards the apices ; their colour is also pale olivaceous green. 



Long. excl. tegm. 30 millim., exp. tegm. 80 millim. 



Hah. Tavoy. Calc. Mus. 



Dunduhia similis, n. sp. 



Above very closely resembling D. radha, Dist,, the thoracic 

 markings similar, but the colour more olivaceous green. It 

 differs from D. radlia^ however, by the shape and length of 

 the opercula, which do not extend beyond the third abdominal 

 segment, and have their apices somewhat obtusely rounded. 



Long. excl. tegm. 50 millim., exp. tegm. 122 millim. 



Hah. Sikkim. Coll. Dist. 



Cosmojpsaltria nigra, n. sp. 



^ . Body above and beneath with the legs blackish ; eyes 

 and ocelli dark fuscous brown. Tegmina and wings smoky 

 hyaline, the venation fuscous, the tegmina with the transverse 

 veins at the bases of the second and third apical areas, and 

 the apices of the longitudinal veins to apical areas, infuscated. 



The rostrum about reaches the apices of the posterior coxas ; 

 the opercula are concavely sinuated a little before centre, 

 their apices convexly rounded and almost reaching apex of 

 fourth abdominal segment. 



Long. excL tegm. 44 millim., exp. tegm. 110 millim.
