Many examples. 



In general form this elegant insect resembles Euderces 

 and other genera of the sub-family TillomorphincB, from 

 all of which it is distinguished by its slender, grooved and 

 spined antenna?, and carinated tibiae. The ground colour 

 is black, but is veiled by a dense silvery-gray pubescence ; 

 and on each elytron there is a large naked black patch, 

 the inner margin of which is curved and does not reach 

 the suture ; on this patch the thick punctuation of the 

 integument is visible, and the middle is crossed by an 

 ornamental belt of an orange or tawny-brovmish colour, 

 near the anterior and posterior m.argins of Avhich runs a 

 fine transverse yellow line. The basal margin is also 

 black, so that the silvery-gray pile is limited in reality to 

 two large triangidar patches, one basal and the other
