 with sliort and sparse white liairs, which are denser at the inner margins of the eyes, 

 and at the front margins of tlie cheeks. Upperside with a narrow longitudinal white 

 streak at eacli side, rnnning from behind the npper lobes of the eyes along the sides 

 of the prothorax to the shonlders, and from here oblicpiely to the middle of the 

 snture, then going parallel to the snture and ending at the beginning of the a])ical 

 fonrth of tlie elytra, where it is united or nearly united with a transverse band. The 

 latter is also white and runs from the sides of the elytra above the base of the 

 second abdominal .segment somewhat oblicjnely towards the snture. The longitudinal 

 band is broadest on the prothorax, and includes the black lateral tooth as well as a 

 lilack basal spot behind the tooth. Spots at the sides of the abdominal segments 

 small, those of the last segment larger. Anterior and intermediate legs clothed 

 with a sparse white pubescence, which is somewhat denser in the middle of the 

 femora and tibiae ; hind femora entirely white, hind tibiae with a white ring. 

 Upperside of the two basal joints of all tarsi more or less white. Front of the 

 head with a dense and very fine punctuation. Lateral teeth of the prothorax placed

 basal white spot. Elytra coarsely, towards the tip more finely punctuated, with the 

 punctures very dense in the middle towards the sides : tip of each elytron somewhat 

 truncate. Process of the prosternum narrow, bearing a rather sharp tubercle 

 between the coxae ; process of the mesosterunm strongly produced underneath and 

 distinctly compressed, rounded at the tiji. The white bands are sometimes tinged 

 with yellow.
