 deep black. Brassy-green, irrorated golden, shining, closely punc- 

 tured : head beneath and feet lighter brassy-green, very shining : venter 

 deep black, smooth, slightly shining. Head much inclined, obtusely 

 triangular, rounded at the apex ; except the tylus, irrorated golden : 

 eyes, ocelli, antennaa and rostrum, black ; 3-5 joints of antennae some- 

 what flattened ; rostrum reaching almost the apex of the second ventral 

 segment, extremity of tip brownish : thorax with three black spots 

 towards the anterior margin, the lateral subovate- oblong, transverse 

 impressed, smoothish, the median irregularly triangular, smallest ; to- 

 wards the posterior margin three larger spots, of which the lateral oblong, 

 longitudinal, and the median obtusely triangular, smallest ; lateral 

 margins reflexed, a very small black spot on the slightly prominulous 

 posterior angles : scutellum with the basal elevation smooth, shining, 

 and with seven black spots ; on each side three lateral, of which the two 

 first are ovate-oblong, transverse, and the third is somewhat rounded 

 posteriorly, also one subbasal median, obtusely- triangular, having its 

 apex pointing hindwards. Head beneath and pectus very bright, shinine* 

 brassy-green ; antennae black : entire venter intensely black, smooth 

 slightly shining ; barely traces, under the microscope in the sun, of a 

 slightly purplish limbus and a slightly brassy-green margin to the 

 stigmata : feet blackish, femora tinted brassy-green towards the apex ; 

 tibiae finely ciliated, externally of a blue-steel colour. Long 14 j breadth
