Genus 33. DUADICUS, n. g. 



Head with the central lobe longer than the lateral. Ocelli 

 placed rather nearer to the eyes than to each other. Antennae 

 inserted a little before the eyes, about half the length of the 

 body, five-jointed; joints variable in length; basal joint longest, 

 reaching far beyond the apex of the head, thicker than the two 

 I following joints ; fourth and fifth joints thicker than the pre- 

 ceding ; fifth thickest, making the antennae slightly clavate. Ros- 

 trum scarcely reaching the posterior coxae, inserted near the apex 

 of the head ; basal joint short, not reaching the base of the head ; 

 second longest; third a little shorter than the second; fourth 

 shorter than the third, about equal to the first. Body broad and 

 short. Thorax with the lateral angles produced into strong acute 

 spines; the antero-lateral margins furnished with a distinct, some- 

 what membranaceous border, which is finely and regularly denti- 

 culated on the edge. Scutellum small, triangular, nearly equi- 

 lateral, scarcely reaching the centre of the abdomen. Coriaceous 

 portion of the elytra not much larger than the membrane, the 

 base of the outer margin furnished with an obtusely angular di- 

 latation. Ventral spine very long, passing the anterior coxae, 

 strong, compressed towards the apex, which is acute. Proster- 

 num with a shallow canal, formed by two slight keels continuous 

 with those of the under surface of the head ; meso- and meta-
