BY THE REV. T. BLACKBURN. 467 



N.B. — I have before me three specimens, — from another locality 

 on Yorke's Peninsula, — which differ from the above in being 

 smaller (long. 2i lines) and differently coloured, the colour vary- 

 ing from deep copper to a dull green, but they are all clothed with 

 pubescence similar to that of T. negligens ; the antennae seem a 

 little shorter than in that species, but as I do not observe any well- 

 defined structural distinction it will be better to regard them as 

 merely vars. 



TOMYRIS OBSCURA, sp.nov. 



Oblonga ; minus nitida ; nigra ; antennarum articulis (ultimis 

 2 exceptis) basi obscure ferrugineis ; corpore supra crebre sub- 

 fortiter aspere punctulato, brevissime sparsius albido-pubescenti, 

 subtus sparsim punctulato sparsim albido-pubescenti ; oculis for- 

 titer convexis ; elytris postice sat abrupte declivibus. 



[Long. 2g, lat. I5 lines. 



This species differs from all others known to me of the genus 

 by its uniform black colour, varied only by a brassy green front 

 of the clypeus, by very short white pubescence which is neither 

 very close nor conspicuous, and by the ferruginous colour of parts 

 of the antennae. It is also notable for having its puncturation 

 decidedly more rugulose on the elytra than on other parts, these 

 organs presenting a slight appearance of striation on the disc and 

 being strongly punctulate-striate, with elevated interstices, in the 

 hinder half of the portion near the lateral margin, and their 

 pubescence tending to run a little in longitudinal lines. The 

 prosternum is evidently wider between the anterior coxae than in 

 T. rasa and most of its congeners. If this species be compared 

 with T. rasa it will be seen that the eyes are slightly less promi- 

 nent, that the prothorax is less convex and less rounded on the 

 sides and that the elytra are much rougher in appearance with 

 indications of striation which is entirely absent in T. rasa. The 

 two or three joints of the antennae preceding the last are some- 

 what compressed, and dilated from the base to the apex.
