370 LAMELLICOKNIA. 



Velvety-opaque ; generally green, but sometimes coppery ; elytra often concolorous, 

 but in most examples with a few or numerous transverse tawny-red spots ; when thickly 

 spotted the thorax is also obscure tawny-red, with the disc or two vague dorsal vittse 

 green. The clypeus is nearly square, i. e. parallel-sided, with the margins raised and 

 the apex more or less sinuated.

Differs from E. mystica in its much smaller size and opaque thorax and scutellum, the 

 latter being smooth, with the exception of a puncture or two near the base. In most 

 respects it is much more nearly allied to E. vestita, from which it differs in the 

 clypeus being narrower, much longer, and more reflexed-sub-bidentate at the apex. 

 E. avita is of rather smaller and more slender form, and offers a somewhat different 

 range of variation ; some examples being dull dark green, a triangular spot on the basal 

 lobe of the thorax and a few transverse undulating spots on the elytra only being 

 fulvous, in which state it resembles a small E. suhnacuhsa. The clypeus in both 

 sexes is as described under E. mystica. In the great majority of examples the elytra 

 are fulvous, with very numerous blackish spots, the thorax blackish with a dorsal 

 line, and a discal spot on each side, and the base fulvous, and in many the lateral and 

 anterior margins are also of the same colour. The antennal club in the male is rather 

 longer than joints 1-7 taken together. The anterior tibiae are tridentate in both sexes, 

 the upper tooth sometimes very short in the male.

The rather clearer orange-tawny colour distinguishes this species from E. vestita, 

 besides the striking difference in the size of the antennal club and armature of the 

 anterior tibiee in the male. The shorter, broader, and squarer clypeus distinguishes it 

 from E. avita. The markings of the thorax are the same as in the clear-coloured 

 examples of both the other allied species. There is scarcely any difference in colour 

 or markings in the seven examples examined.
