extending on the sntnro td the scutenum, iiud incliidiuga lyriform grey marking, the 

 tip of which does not qnite reach tlie scntellnm ; tlie pubescenee denser beyond the 

 middle than at the apex, so that there is an ill-defined postmedian transverse grey 

 band ; each elytron has, moreover, a humeral longitudinal black streak, the inside 

 of wbicli is connected with the largo autemedian black macula by a very fine 

 black line.

 second segment is black.

Black, clothed with an ashy grey pubescence. Scape of the antennae as long 

 as the third joint. Prothorax finely granular, a little more rounded posteriorly than 

 before the middle. Jlarkings of fhe elytra similar to tliose of the jjreceding species, 

 but the humeral line is short, and the large black sidj-basal baud sends out on each 

 elytron a fine and short line which does not (piite extend to fhe basal margin.

Long. 7 mm., elytr. 4^, lat. 2. 



Black, clothed with an ashy grey pubescence. Front densely and rugosely 

 punctured; antennae reaching the nuddle of the elytra, feebly pitchy, chiefly at the 

 base ; third joint elongate. Prothorax regularly and rather strongly reticulated. 

 Scntellnm triangular, black. Elytra obliquely truncate at the apex, rather strongly 

 toothed at the outer angles, and feebly so at the inner ones, with a broad black 

 transverse median band, which is narrowly dilated on the suture towards the 

 scntellnm and is bordered with white hairs, chiefly in front ; before the baud in the 

 middle of the base of each ilyti-on is a small inconspicuous black spot ; the grey 

 pubescence sparse at tlie apex, the latter almost black. The first abdominal 

 segment bears a white spot at eacli side, or its whole posterior part is wliite.
