PACHYTERIA CALUMNIAÏA. 167 



Head, prothorax and elytra black, the latter with vio- 

 laceous and bluish or greenish tints ; the antennae , meso- 

 and metasternum , legs and abdomen steely blue ; the 7th 

 and succeeding antenual joints yellow, the base of the 

 7th and the narrowed apical portion of the 11th black '); 

 the elytra provided , somewhat before the middle , with a 

 yellow transverse band, which has nearly parallel margins; 

 sometimes, however, the hind margin is, on each elytron, 

 slightly oblique or even faintly emarginate. 



The head is glabrous, remotely and deeply punctured, 

 more densely so on the vertex ; the clypeus hollowed , with 

 raised margins and divided by a raised keel along the 

 middle; the frontmargin of the clypeus minutely notched 

 in the middle ; the interantennary ridge divided by a deeply 

 impressed line. 



The pronotum glabrous, uitid, sparsely punctured, es- 

 pecially on the middle of the disk; the prosternum scar- 

 cely at all punctate , sericeous in the cT, the intercoxal part 

 rounded, without tubercle ; the intercoxal part of the meso- 

 sternum without V-shaped recess; the mesosternum ^) and 

 the sides of the metasternum covered with a dense silvery 

 grey pubescence ; on the glabrous middle portion of the 

 metasternum a longitudinal line and a few punctures are 

 to be observed. 



The scutellum very acutely triangular, flat, glabrous and 

 provided with a few very fine punctures. 



The elytra slightly tapering towards the end , the apices 

 separately rounded and consequently somewhat dehiscent 

 at the suture; pubescent and very finely and densely punc- 

 tured all over. 



The abdomen with a few scattered fine punctures, the 

 sides covered with a silvery grey pubescence. In the male 

 the 5th segment is broadly and deeply emarginate , the 6th 



1) In the single female I have seen (from the collection of Mr. Neervoort 

 van de Poll) only the extreme tip of the 11th joint is dark coloured. 



2) In the female the middle portion of the mesosternum is glabrous.
