Apart from the carinae of the mesonotum Mnemosyne and 

 Oliarus appear to differ only in the width of the vertex, and as 

 the width of the vertex varies in the different species of Oliarus it is 

 difficult to draw the line between them. Until the type species of 

 Mnemosyne is redescribed I shall consider that it has three meso- 

 notal carinae and describe all those having five, and only differing 

 in the width of vertex, as Oliarus. 



Oliarus kempi, sp. nov. 



Female. Length 43 mm. ; tegmen 5-3 mm. 



Length of vertex 3 # 3 times the width at base, base slight^ 

 wider than apex, inner carinae leaving lateral carinae one-third 

 from base, gradually converging to apex where they meet and 

 touch the apical transverse carina. Face very narrow at base ; 

 median carina forked at base. Fronto-clypeal suture straight at 

 sides, the middle half rounded. Median ocellus present a little 

 distance before apex of face. Forking of Sc and R slightly distad 

 of fork of Cu. 



Pygofer oblong, broader than long (i"8 to 1). Anal segment 

 small, half the width of pygofer, ovate, anus at apex. p Genital 

 styles not quite so long as anal segment. Hind margin of pregeni- 

 tal plate slightly emarginate in middle, the corners forming a small 

 angular projection. 



Dark brown ; carinae of head and pronotum, abdominal 

 pleura and hind margin of segments yellow. Tegmina hyaline 

 very slightly infuscous, darker over apical portion ; veins brown 

 with small tubercles bearing small, black macrotrichia. 



Described from one female specimen from Talewadi, near 

 Castle Rock, North Kanara District, Bombay Pres. (S. Kemp, 

 October, 1916). 



Oliarus kierpurensis, sp. nov. 



Male. Length 37 mm. ; tegmen 5 mm. 



Vertex a little longer than width at base (1*3 to i), base 1*4 

 times the width at apex. Latero-median carinae leaving lateral 

 carinae about one-third from apex, converging and meeting 

 together a little before apical transverse carina to which they are 

 joined by a short carina ; base angularly emarginate. Fronto- 

 clypeal suture forming a half circle. Median ocellus present at 

 apex of face. Cu forking slightly basad of Sc and R. 



Lateral margins of pygofer rounded, medio- ventral margin 

 produced into a small, sublanceolate process. Anal segment large, 

 dorsal surface tectiform, ventral surface concave, anus at apex 

 which is slightly narrowed and emarginate. Genital styles large, 

 flattened, elongate, S-shape with the apex widened. 



Dark brown ; carinae of head and pronotum and the middle 

 of pronotum, legs and basal half of abdominal segments yellow or 

 light brown; carinae of mesonotum slightly lighter than disc. 

 Tegmina clear hyaline, veins light yellow, tubercles small, yellow,
