Allied to hicarinata and with somewhat similar legs, but 

 fourth segment of abdomen of male shorter, carinated along 

 middle, and with but feeble elevations at the positions of the 

 acute carinae of that species; the third segment is also different, 

 as it has a short acute ridge (from the side it appears almost as 

 a subconical tubercle) at about one-third the width of the 

 segment from the side ; the second appears to have remnants 

 of similar elevations in a line with those on the third. The 

 femora, palpi, and antennae are mostly flavous ; parts of the 

 under-surface are paler than other parts, but the various 

 shades of colour are not sharply limited.

PI. viii., fig. 161. 



S . Brassy-brown, or bronzy, or brassy-green ; under- 

 surface blackish, with a bluish or greenish gloss, but tip of 

 abdomen diluted with red ; labrum, front of clypeus, and 

 appendages more or less reddish, but apical joint of palpi and 

 apical half (or less) of antennae blackish. 



Head shallowly depressed between eyes, median line 

 rather feeble ; with irregularly distributed punctures of 

 moderate or rather small size, becoming very small on front 

 of clypeus. Antennae rather long and thin, third and fourth 

 joints subequal. Frothorax about twice as wide as the median 

 length ; with large and not very dense punctures, becoming 

 sparse towards middle. Elytra with punctures and striae 

 much as on anomogastra. Flanks of frosternum with some 

 punctures about base only, elsewhere shining and with a few 

 wrinkles. Third segment of abdomen with a rather short 

 median ridge, fourth distinctly longer than third, with a con- 

 spicuous subtriangular median ridge, behind same oblique to 

 apex, fifth irregularly transversely depressed, and with a 

 median fovea. Front femora strongly dentate ; hind tibiae 

 feebly dilated from base to middle, and then gently curved 

 to apex ; basal joint of four front tarsi rather strongly dilated, 

 of the hind ones elongate-triangular. Length, 6-7 mm. 



9 . Differs in being more compact, abdomen more convex 

 and simple, legs shorter, hind tibiae gently dilated from base 

 to apex, and in the tarsi.

Fairly close to elegantula, but male with basal joint of 

 four front tarsi less conspicuously inflated, and of the hind 

 ones much shorter and differently shaped. Heroni is of 

 smaller average size, with the abdomen of the male very 

 different, and basal joint of hind tarsi distinctly longer
