Genus 2. BARDISTUS. 



Head small, filled up between the antenniferous tubercles ; 

 eyes small ; ocelli placed close to the anterior margin of the 

 thorax, rather more distant from each other than from the eyes. 

 Antennae cylindrical, about two-thirds the length of the body, of 

 four joints ; basal joint rather long and stout, thickened towards 

 the apex; second joint shorter than the first, longer than the 

 third, which is cylindrical ; fourth longest, thicker than either the 

 second or third, twice as long as the latter. Rostrum short, 

 reaching the middle of the mesosternum, of four joints; basal 

 joint stout, reaching the base of the head ; second and fourth 

 joints about equal ; third shorter. Body ovate, broad, with the 

 sides of the thorax considerably dilated and rounded, with the 

 margins denticulated. Scutellum short, triangular. Membrane of 

 the elytra ample, with numerous, longitudinal, more or less ana- 

 stomosing nervures. Abdomen ovate, broad, projecting on each 

 side beyond the elytra, with the margins entire ; the male has a 

 distinct longitudinal central furrow, which is not perceptible in 

 the female ; the last segment is more or less cleft longitudinally 

 in both sexes. Legs moderate ; four anterior in both sexes with 

 two spines close to the apex of the thighs, and the tibiae prismatic ; 

 in the male, the posterior thighs are considerably thickened, with 

 a large spine beneath before the middle, two smaller ones between 

 this and the apex, and a spine on each side of the knee-joint ; 

 tibiae slightly compressed, furrowed on each side and along the 

 outer margin, slightly curved outwards at the apex, and armed 

 on the inner margin with two spines ; in the female the posterior 

 thighs and tibiae are nearly of the same form as the others, but 

 longer ; tarsi three-jointed, posterior pair longest ; basal joint as 

 long as the other two together ; second joint shortest ; claws 

 moderate.
