rather stout, inserted towards the apex of the head on a level 

 with the insertion of the antennse, reaching or passing the base 

 of the posterior legs ; basal joint passing the base of the head, 

 but not reaching the anterior coxae, as long as the third and 

 fourth together; second longest, third rather longer than the 

 fourth. Rostral canal with the walls very high, especially towards 

 the anterior portion. Thorax with the lateral margins denticu- 

 lated, the humeral angles more or less spinous. Scutellum of 

 moderate size, triangular, with the apex rather broad. Coria- 

 ceous portion of the elytra much longer than the membrane, 

 with the apical margin very oblique, but with the outer angle 

 abruptly truncated ; membrane reticulated with strong black ner- 

 vures. Abdomen and metasternum with a distinct central fur- 

 row, which reaches the posterior margin of the fourth ventral 

 segment. Legs rather long; tarsi with the basal joint as long

Genus 14. SPUD^EUS, n. g. 



Head rather elongated, somewhat pointed in front, central lobe 

 much longer than the lateral and projecting considerably beyond 

 them at the apex of the head. Antennae rather stout, nearly as 

 long as the body, inserted near the middle of the lateral lobes of 

 the head, five-jointed; basal joint thickest, somewhat clavate, 

 reaching beyond the apex of the head; second joint not much 

 longer than the first. Rostrum very long, reaching the posterior 

 margin of the fourth segment of the abdomen, inserted about on 

 a level with the base of the antennae ; first joint not passing the 

 base of the head, entirely enclosed within the canal of the under 

 side of the head ; second and third joints very long, about equal, 

 the tip of the third reaching the posterior margin of the second 

 ventral segment; fourth joint about equal to the first. Body 

 ovate, somewhat elongate. Thorax with the lateral margins 

 denticulated or crenulated anteriorly, the lateral angles produced 

 into acute spines. Scutellum triangular, rather elongate, with
