tlie Ilcmiptera collected in the Amazons, §^c. 273 



Unfortunately, all the specimens I have seen are 2 s, 

 and therefore I know nothing of the structure of the 

 $ abdomen, and cannot say Avhether it is asymmetrical or 

 whether a strigil exists. Though the facies of the insect 

 is quite that of Corixa, the form of tlie eyes and the 

 structure of the left hemelytron brings it into relation 

 with Signra, and the short pronotum somewhat resembles 

 that of Cymatia. When the structure of the i is ascer- 

 tained, it may be necessary to give Heterocorixa generic 

 rank.
