SENOCLIA BILANGA, new species. 



This species is closely allied to caerulea Cameron, but may be dis- 

 tinguished by the characters used in the foregoing key. The female 

 is very like Cameron's species, and the differences are comparative 

 and hard to express. The male is, however, easily distinguished. 



Female. — Length, 11 mm. Clypeus flat; supraclypeal area very 

 slightly convex, triangular in outline; antennal furrows well defined, 

 complete; middle fovea large, shallow, and with a median tubercle; 

 ocellar basin deep, well defined, U-shaped, extending behind ante- 

 rior ocellus, as a furrow, to the postocellar furrow; postocellar line 

 distinctly shorter than the ocellocular line; postocellar furrow well 

 defined, curved; postocellar area gently convex, about one-third 

 wider than long; front, especially the ocellar area, with setiguous 

 punctures; third and fourth antennal joints subequal, joints six and 

 seven slightly wider than the preceding or following; sheath broad, 

 straight above, obtuse apically, rounding to base; cerci short. Dark 

 metallic blue, with a purplish tinge; antennae and legs black; wings 

 deep violaceous. 



Male. — Length, 9 mm. Hypopygidium truncate. Structure as in 

 female. 



Type locality. — Kollegal, 2,000 feet (about 606 meters), Coimba- 

 tore, S. India.
