Type, H. scissa, Roger, from Ceylon. 

 Range. The Indo-Malayan region. 



^ . Characf-ers very like those of PohjrJuichis, Smith, but the 

 compound eyes, instead of being round and com- 

 plete, are incised or truncate posteriorly. In the 

 ^^. X typical species, H. scissa, the thorax is almost 

 ^- 1 divided into two parts by a deep and comparatively 

 broad furrow at the nieso-metanotal suture, the 

 prouotum is triangular, the apex pointing back- 

 wards ; the mesonotum is attenuate, consisting 

 p-^ J.,., virtually of two triangular points, one on each 



Heidiop'fica, side, sunk below the level of the pronotum ; the 

 g head. basal portion of the metanotum is roundly curved, 



the apical portion, separated from the basal por- 

 tion by a distinct transverse carina, slightly concave. In the 5 > 

 however, the peculiar deep furrow succeeding the mesonotum is 

 placed behind the scutellum ; in the ^ of the two other Indian 

 species belonging to this genus it is wanting. The rest of the 

 characters of Hcmioptica are identical with those of the genus 

 Polyrhachis. 



Key to the Species.
