N. B. Attempts have been made of late to use the name Tri- 

 atoma Lap., instead of ConorJmius. As the name Triatoma was 

 proposed under the misconception that the antennae are three- 

 jointed in this genus, and as it therefore was rejected by Laporte 

 himself as inappropriate and misleading and altered to Conorhinus 

 in the same paper, there is, however, no sufficient reason to 

 discard the name by which the genus has been known nearly 

 eighty years.
