(^ ? . l^lack or piecous, with inconspicuous and easily 

 al)raded dark scalinj^ on the disk of the elytra, and with the 

 f()ll()\vin<i: markings formed of pale metallic-j^reen scales : — 

 A stripe alonj^ tlie inner edge of each eye and the whole 

 side of the head and rostrum ; a narrow median stripe on 

 the ])rothorax, a broader lateral one behind the eye, and 

 another above the coxa ; elytra with a stripe on interval 1 

 from behind the scutellum to about the middle, a short 

 humeral stripe on 7 from the base to about one-third, a 

 romi)letc marginal stri[)e rcachir)g stria 9, but broader at 

 tlie apex and emitting at the midille a more or less dentate 

 broad oblique Ijand, which reaches the suture at the top of 

 the declivity and is united by a sutural stripe to the ai)ical 

 ))atch ; a very short isolated stripe at the apex of interval o, 

 and occasionally a still shorter one at the apex of 7 ; in the 

 ? only there is a round spot at the middle of interval 3 and 

 a trace of another on 5. The lower surface rather thinly 

 clothed with ])ale greenish scales. 



Head with strong, longitudinally confluent pnnctation, a 

 deeply impressed line along the itnier margin of the eye, and 

 a large central fovea; eyes rather less prominent than usual, 

 (leei)est in the middle. Rostrum a little longer than broad 

 [7 -.(S), parallel-sided, almost flat on the disk, coarsely and 

 coufluently punctate, with a low smooth median costa (rather 

 broader and flatter in the ? ) which widens anteriorly, a low 

 })unctate costa forming the margin of the dorsal area, and 

 l)eneaih it a longitudinal impression in front of the eye. An- 

 tenuic with the two basal joints of the funiele equal, joints 3-7 

 snl)0(jual and about as long as broad, the flrst joint of the 

 club narrow and subcvliudrical in its basal half. Protfioiox 

 about as long as the apical width, the sides subparallel from 

 the base to the middle, then gradually narrowed to the apex, 

 the apical margin broadly sinuate (as seen from above) 

 owing to a markeil thickening behind the eye, the base very 

 .shallowly bisinuate, the longitudinal outline nearly flat; the 

 upper surface with close shallow punctures of varying sizes, 

 each Hllcd with a flat scale, the median line often very 

 shallow ly impressed in the basal half. Elytra narrowly
