It is not unusual to come across this representative of the family

more coarsely pitted and the elytra marked with parallel punctured 

 stria?, the ventral surface and legs also being finely pitted. It was 

 described by the Rev. T. Blackburn 17 in 1900. Mr. Walter "W. 

 Froggatt 18 gives a brief account of this species and figures an adult. 

 He states that the insects were bred from the pseudo-bulbs or thick- 

 ened leaf stalks of Dendrohium canalicidatum and gives the follow- 

 ing description of the larva and pupa.
