 the ria<^elluni is fully as loiig as the third. Tlie broad forni 

 of the seventh dorsal sejiiiient is remarkable.

I had idontitied this species as xantJiopns, BruUe, in my 

 recent paper on Pison (Froc. Zool. Soc. 191()), but since 

 then have found otiier specimens answering much better to 

 Brulle's description. The present species may possibly be 

 obscuruSf Siiuck., but the t} pe of that species is lost and 

 the description gives the pubescence of the front as golden, as 

 in xanthopus.

Four females in the National Collection answer well to the 

 description. They differ from carinatuin and strigulosum in 

 the bright golden pul)escence of the front and in the red 

 colour of the two or three apical abdominal segments. There 

 is no basal carina on the cly{)eus as in cariiiatus, which it 

 resembles in the sculpture of the median segment, and differs 

 in the latter point trom strigulosum. The cly|)eus is more 

 distinctly truncate at the apex than in either of the other 

 species. P. c/gpealus, Cam., seems to belong to the same 

 group. I do not think that Shuckard's description of 

 obscurus can be meant for the present species.
