Hah. West Australia (Nicol Bay). 



This species is allied to P. miliaria, which, with scenica, 

 picta, sectator, and cra^sicollis, seem to constitute a group some- 

 what different from the ordinary Pentheie. Lacordaire (Gen. 

 X. p. 560) says the genus is easily known by two tomentose 

 depressions of the abdomen in both sexes ; and in a note he 

 adds, " No autlior that I know of has mentioned this cha- 

 racter." I had, however, previously called attention to it in 

 a species of a closely allied genus, SymjyJiyletes puhiventris 

 (Joum. of Entom. i. p. 339), but in which the two patches 

 were so close together as to cover nearly the whole of the 

 segment. Subsequently I found that this character miglit or 

 might not exist in the same species, or in either sex ; and it 

 seemed to me so unsatisfactory, that, as a rule, I have ceased 

 to nicutioii it.
