strongly punctate, punctures larger and more widely spaced in front ; intervals 

 almost flat, each finely and irregularly punctured in about two indefinite series.

Possibly the insect recorded by Gebien as Palorus, sp. from Dr. Friederich's 

 collection. 



In its broad form and non-parallel elytra this insect more closely approaches 

 the Australian P. pygmaeus Cart, than any other species known to me, but is 

 smaller, with longer antennae and relatively broader clypeus. P. austrinus 

 is relatively much longer, more than three times as long as wide, with the elytral 

 intervals fairly regularly uniseriate-punctate. The specimen from Apia (type) 

 is a little larger than those from Malololelei, and more darkly coloured, the 

 latter having the elytra near the tip and towards the shoulders indistinctly 

 paler.

The locality " Sandw. Is." on a male in the Fry Collection is no doubt a 

 misreading for " Samoa Is." 



Fairmaire's type of U. cavicollis from the Doue Collection is now in the 

 British Museum, and agrees exactly with a rather poorly developed <$ from 

 Samoa. The specimens forming the short series from the Ellice Is. differ from 

 Samoan examples in having a much smaller excavation on the thorax of the 

 with the prominences very poorly developed ; also in the thorax being com- 

 pletely immarginate at the base. In U. cavicollis there is a fine but more or 

 less entire margin. The Ellice Is. form agrees with the typical one in having
