Readily distinguished from all other described species by the 

 remarkable process on the metasternum, which is very distinct 

 from the sides; the process is somewhat similar to that on the 

 males of several species of Mandalotus (M. hoplostethus, M. inter- 

 coxalis, etc.), only it is placed on the metasternum, instead of on 

 the mesosternum. There were two males of the species, in the 

 Maclciiy Museum, standing under the name of H. o^jfata, but they 

 are not even close to the description of that species, differing in 

 the abdomen, metasternum, prothorax, antennje, ifec.
