124 Description of Australasian Tridioptcrygia. 



Legs rather long and slender, the tibiae moderately 

 dilated towards their apex, bright yellow. 



Underparts castaneous, with the mouth, prothorax, and 

 terminal segments of the venter paler. 



A very distinct and pretty species. In its foveolate 

 punctuation it resembles Pt. punctatum, but is easily recog- 

 nized by its bright castaneous colour and more ovate form, 

 and especially by the absence of the smooth impunctate 

 and very shining space on the disk of the thorax, so con- 

 spicuous in the latter species. Three specimens were 

 found near Auckland, in New Zealand, by Mr. Lawson, 

 and forwarded by him to Dr. Sharp, through whose kind- 

 ness I received the pair from which this description has 

 been made.
