A single female specimen has an elytral pattern somewhat 

 as in latithorax, Thorns., or thoracica, Saund., with a darker 

 ground colour than either of these. The sculpture of the 

 elytra is somewhat like that of gigas, Gehin., or latithorax, 

 Thorns., but the smaller more attenuate, concolorous pro- 

 thorax easily distinguishes it from these. The surname and 

 Christian name of the distinguished naturalist in whose col- 

 lection the type is contained being both preoccupied in 

 Stigmodera I have used a Latinized form of his name to 

 denote this fine species.
