King George's Sound, West Australia ; Bateman's Bay, New 

 Soutli "Wales. Under bark. 



This fine Xanthophcea will readily be recognised by its uniform 

 testaceous colour, smooth surface and narrowly margined pro- 

 thorax. 



Genus Plagiotelum. 



Solier in Gay's Hist, de Chile, Zool. IV., p. 132 (1849). 



The species which I here refer to this genus, hitherto only 

 known from Chili and Port Famine, near the Straits of Magellan, 

 is interesting as being a new and striking example of an 

 Australian form, finding its nearest ally in a genus from the west 

 coast of South America. 



Plagiotelum opalescens, n. sp. 



Testaceous, shining, with bright green reflections ; head and 

 prothorax bright metallic green, the latter with the sides only 

 slightly narrowed behind ; elytra iridescent, moderately strongly 

 striate, the apex dark green. 



Head considerably longer than broad, narrowed behind, 

 impunctate, the antennal impressions distinct ; . epistoma truncated 

 in front. Antennae reddish testaceous, the basal joint moderately 

 long, the second very short, the third longer than the following 

 joints which are covered with fine pubescence. Prothorax a little 

 broader than long, slightly narrowed behind, finely aciculate near 

 the sides; anterior angles very slightly produced; the lateral margins 

 rather strongly reflexed ; the median line not very distinct. 

 Elytra moderately convex, about twice as long as the head and 

 prothorax together, a little narrower in front than behind, rather 

 strongly striate, the interstices moderately broad, slightly raised 

 and impunctate ; humeral angles rather prominent ; the lateral 

 margins reflexed. Underside bright metallic green, with bluish 

 reflections ; the sides of the head and sterna extremely finely
