Genus HEMIOPTICA. 



Hemioptica, Roger, Berl. ent. Zeit. vi (18G2), p. 238, . 

 Polyrhachis, pt., Forel, Jour. Bomb. N. H. Koc. viii (1893), p. 17. 



Type, H. scissa, Eoger, from Ceylon. 

 Range. The Indo-Malayan region. 



. Characters very like those of Polyrhachis, Smith, but the 

 compound eyes, instead of being round and com- 

 plete, are incised or truncate posteriorly. In the 

 typical species, H.' scissa, the thorax is almost 

 divided into two parts by a deep and comparatively 

 broad furrow at the meso-metanotal suture, the 

 pronotum is triangular, the apex pointing back- 

 wards ; the mesonotum is attenuate, consisting 

 virtually of two triangular points, one on each 

 side, sunk below the level of the pronotum ; the 

 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 2 , 

 however, the peculiar deep furrow succeeding the mesonotutn 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 ffemioptica are identical with those of the genus 

 Polyrhachis. 



Key to the Species.

. Black, shining, very minutely reticulate-punctate, the cheeks 

 posteriorly a little more coarsely rugulose, and the sides of the 

 thorax behind the meso-metanotal suture finely obliquely striatej:
