 dilated, elliptical, very thin at base and apex ; apical joint shortest, 

 rather more than half as long as the first. Rostrum reaching the 

 base of the intermediate coxae, of four joints ; basal joint reaching 

 the base of the head, enclosed at its base in a short canal ; second 

 and fourth joints about equal, about as long as the first ; third 

 joint shortest, half as long as the first. Body oblong ovate. 

 Thorax with the lateral margins irregularly serrated, produced on 

 each side into broad, flat, strongly-toothed processes. Membrane 

 of the elytra with longitudinal nervures, occasionally anastomo-
