(S . Feniinte siniilis ; clypeo apice truncate, couvexo. 



5. Clypeus concave on the apical half, broadly truncate at the apex, 

 Antenn£e inserted a little nearer to the base of the clypeus than to the an- 

 terior ocellus, the second joint of the flagellum equal to the third. Cheeks a 

 little more than half as broad as the eyes. Pronotum not depressed in the 

 middle, rounded at the angles ; mesopleurse without spines. Basal abdominal, 

 segment a little longer than broad, constricted at the apex. Second ventral 

 segment with a raised area at the base ; pygidial area elongate ovate, 

 narrowly truncate at the apex. Strongly punctured, more closely on the 

 head than elsewhere ; the enclosed area at the base of the median segment 

 punctured, obliquely striated in the angles and at the apex, with a deep 

 median groove. First recurrent nervure received at one-fifth from the base 

 of the 2nd cubital cell. Black ; mandibles, except at the apex, clypeus, 

 front, a spot on each side of the pronotvim, tegulee, a small spot at the 

 anterior angles of the scutellum, a narrow apical band on the third dorsal 

 abdominal segment, another on the fifth, the whole of the third ventral 

 segment, a spot on each side of the fifth, tibiee and tarsi yellow ; first 

 abdominal segment and second ventral segment ferruginous red, antennae 

 testaceous brown, the scape yellow beneath. Wings hyaline, with a very 

 faint fuscous cloud at the apex, nervures testaceou.s. 



cJ . As in the female ; but the clypeus is longer than broad, narrowly 

 truncate at the apex ; the pygidial area very small, coarsely punctured, 

 truncate at the apex, twice as long as the greatest breadth, very 

 slightly narrowed towards the apex. 



Habitat. — Ceylon, Colombo {Wickicar) . July to September, March 

 to April. 



In structure this resembles the last species (allopicta), but the second 

 ventral segment is not evenly punctured, being almost smooth at the apex. 

 The size and colour are also difi'erent.
