BOLBOPHANES SERICATUS, 11. Sp. 



Shortly ovate, very convex, (longitudinally and transversely) 

 glabrous, moderately nitid; above, rich dark purple, underside, 

 metallic blue; elytral suture greenish, pronotum with some vari- 

 coloured reflections; legs and antenna? violet. 



Head densely punctate, epistomal suture straight, eyes sepa- 

 rated by a distance equal to the diameter of one, antennae rather 

 fine, scarcely reaching base of prothorax, its joints slightly 

 enlarging outwards. Prothorax 2'5 x 5mm., widest at base, apex 

 strongly emarginate, anterior angles rounded but prominent, 

 base strongly Insinuate, median lobe widely produced ; sides 

 rounded, posterior angles rectangular, lateral margins thick on 

 basal two-thirds, evanescent on anterior third. A rather wide 

 concavity within this margin; disc densely and uniformly finely 

 punctate; without trace of medial line. Scutellum equilatero- 

 triangular, finely punctate. Elytra of same width as prothorax 

 at base, slightly gibbous at shoulders; the whole surface with a 

 satiny gloss, finely wrinkled and lined; the lines in the sutural 

 region irregular; those on the disc and lateral regions becoming 

 wavy but longitudinal (substiiate), with transverse wrinkles of a
