 The faintly defined markings on the eh'tra of this species Ijear 

 a general resemblance to those of /'. obliterata (as described 

 above) except the subapical one, which consists of a dark patch 

 on the 8th interstice, the middle of which is slenderly connected 

 (in some examples not connected) with another and similar patch 

 on the 4th interstice. The markings are quite traceable in all 

 the specimens I have seen, though very faint in some. Apart 

 from colour and markings, P. Galatea differs, inter alia, from 

 obliterata, Er., and pulceriilenta, Blackb., by its notably shorter 

 and more robust antenna, from minor, Marsh., by its considerably 

 less convex form, and from all of them by the puncturation of its 

 elytra, the seriate punctures becoming somewhat finer near the 

 apex than they are in front, and the interstitial punctures being 

 closer and stronger than in the other species, so that some of the 

 series (especially the 3rd) are in their subapical portion not ver}^ 

 distinct from the general puncturation of the interstices, which 

 are absolutely flat.

P. INTERRUPTA, Chp. 



This species is readily recognisable by the characters indicated 



in the foregoing tabulation. It is of very small size (long. H 



lines), with robust antennae, some of the external joints of which 



are very little longer than wide, and of testaceous-brown colour 



with the suture of the elj^tra (except close to the base) widely 



and two wide vittfe (these coalescing at the base and apex) of a 



much darker brown colour. I have seen only one example, which 



was named by Dr. Chapuis. The insect is said to be found in 



N.S. Wales.
