480 Mr. T, D. A. Cockerell — Descriptions and 



colour. Other characters are: abdomen brilliant crimson- 

 purple, with some golden tints; clypeus with large well- 

 separated punctures on a shining ground ; mesothorax olive- 

 green, strongly punctured; second s.m. broad, receiving the 

 first r. n. about its middle ; third s.m. not very much larger 

 than second, receiving the second r. n. very near its end ; 

 sides of metathoracic enclosure with numerous raised lines ; 

 hind spur of hind tibia pectinate with five long spines ; all 

 the tarsi, hind tibiae, parts of the other tibiae, and the knees 

 red. 



Ilab. Queensland (Gilbert Turner, Ridg. 11. 93, 863). 



The typical P. cuprms came from Adelaide ; it is very 

 likely that the Queensland insect should be regarded as a 

 distinct species, but it has all the principal characters of 

 ciqjveus, and for the present I treat it as a subspecies. Its 

 colours remind one of some of the Neotropical species of 

 Augochlura.

In all respects this is very similar to P. plumosiis (Sm.), 

 described from a female. Were it not that the venation 

 ditters somewhat, I should think plumosdlus to be the male 

 of plumosus ; and as it is, I am not wholly without doubt. 

 Australian students must settle the matter by collecting the 

 sexes together.
