leiigtli). In successive examples the fuscous scales become paler 

 and the light scales more greyish till they come to almost the 

 same colour, when the surface presents a pale fawn colour with 

 the markings not much paler, and then in other examples all the 

 markings of the elytra except the lateral ones are nearly wanting. 

 I have examples before me in which the groundcolour is dark 

 fuscous and there is only the feeljlest indication of the markings, 

 but I think these are all more or less abraded, or at least old and 

 faded. It is quite possible that I am mistaken in associating all 

 these forms, especially as tliere seems to Ije some variation (apart 

 from sex) in the transversity of the prothorax, but after a good 

 deal of consideration I find myself quite unable to discover stable 

 characters for subdividing them.

mixtis et setis erectis sat brevibus sat validis vestitus, antennis 



pedibusque (femoribus subinfuscatis exceptis) sordide testa-

truncato antice subemarginato ; scutello vix manifesto ;

The examples examined appear all to be females, and none of 



them have any distinct markings, the scales being dull grey 



obscurely mottled with a paler tint. None of them are very 



fresh, and it is likely that freshly taken specimens are more or 



less distinctly and probaV)ly very variably marked with a pattern ; 



probably also the convexity of the elytral interstices is little 



apparent in quite fresh specimens. The characters of this species, 



however, are quite independent of the squamosity, which is 



probably too variable to be available for identification. The 



scape of its antennae is evidently longer than in P. comosics, 



Germ., and considerably longer than in P. Hopei, Schonh,, reach-
