Shuckard states that the carina in the longitudinal groove 

 on the median segment is obsolete in this species. In a 

 series of twenty specimens collected by myself the carina is 

 usually quite distinct near the base of the segment, but there 

 is considerable variation in this character. I have recorded 

 the continental form of this species as P, I'ridipeune, Sm. 

 (Proc. Zool. Soc. p. 512, 1908), but the form of tiie clypeus 

 differs in that Hawaiian species, being broadly and evenly 

 rounded, whereas in westwoodi it is distinctly produced in the 

 middle. The two forms are, however, very close. The 

 posterior ocelli are nearer to the eyes in tridipenne than in 

 typical westwoodi, but North Queensland specimens of west- 

 woodi come very near iridipenne in this point. P. icestwoodi 

 is probably spread over the whole of Australia.
