The description of E. sfriafuf!, Shp., is so brief that it is 

 not practicable to specify the distinctions between it and the 

 present insect further than by mentioning that the larger size 

 of E. Mauricei and the red colouring of the basal two-thirds of 

 its elytra no doubt sufficiently distinguish it. I have called the 

 front area (of the three areas into which the head is divided) 

 the "labrum," although I am doubtful whether that area is 

 really a true labrum. Dr. Sharp calls it the labrum, while 

 Lacordaire considers it a part of the clypeus. The sculpture 

 of the front tibise (which have only a single external tooth 

 above the apical projection) is not usual in the Australian 

 Melolonf hides. The Systellopides form a most interesting and 

 isolated group of LameUicornts.
