HEMIPTERA, 161 



ellum rather small, triangular, scarcely passing the middle of the 

 abdomen. Coriaceous portion of the elytra much longer than 

 the membrane, rounded at the apex; membrane with a large 

 basal cell, from which numerous forked nervures arise. Abdo- 

 men with a distinct, but not very strong, furrow, which attains 

 the posterior margin of the antepenultimate segment.

Entirely deep black, opaque, finely and not very thickly punc- 

 tured. Body beneath rather pitchy. Legs pitchy black, with 

 the apices of the tibiae and the tarsi ferruginous. Rostrum with

Genus 8. MAZIUM, n. g. 



Head broad at the base, narrowed, rounded in front, central 

 lobe as long as the lateral ; lateral margins waved. Ocelli mi- 

 nute, distant, placed close to the anterior margin of the thorax. 

 Antenniferous tubercles slightly spinous on the outside. An- 

 tennae about half the length of the body, rather slender, five- 

 jointed ; basal joint stout, very short, not reaching the anterior 

 margin of the head ; second joint longer ; third, fourth and fifth 

 joints nearly equal, longer than the second. Rostrum reaching 

 the posterior margin of the second segment of the abdomen. 

 Body rounded ovate, rather wider behind, convex. Thorax tra- 

 pezoidal, the anterior margin broadly emarginate for the reception 

 of the head, lateral margins straight. Scutellum reaching rather 

 beyond the centre of the abdomen, triangular, broad at the base, 

 with the lateral margins nearly straight. Coriaceous portion of 

 the elytra reaching the apex of the scutellum, with the apical 

 margin rounded ; membrane nearly rudimentary, forming scarcely 

 more than a narrow border round the apex of the corium. Ab- 

 domen with a strong furrow towards the base. Legs rather stout ; 

 tarsi three-jointed, basal joint longest.
