446 AUSTRALIAN COLEOPTERA, WITH DESCRIPTIONS OF NEW SPECIES, 



margins except in front is of a fiery copper colour changing inter- 

 nally to bright green, while the disc is occupied by a large black 

 triangle, the front being its base and its apex falling behind the 

 middle. The colour of the elytra is across the base (widely) 

 brilliant golden which changes gradually backward to green ; a 

 large common purplish-black patch occupies the middle part, — its 

 front considerably before, its apex a little behind, the centre of 

 the suture ; in some lights a smaller common subapical patch of 

 similar colour is apparent. 



The insect is evidently a Eutoma. The head across the eyes is 

 scarcely narrower than the prothorax which is of the same width 

 as the elytra (by measurement; it looks decidedly wider at a 

 casual glance). The frontal sulci are very strong, diverge strongly 

 hindward to the level of the back of the eyes, and are connected 

 behind by a very strong transverse impression ; there are two 

 supra-orbital punctures. The prothorax is slightly transverse (as 

 7 to 6), its front truncate, its base slightly concave ; the lateral 

 margins bear three strong setiferous punctures on either side. 

 The basal cluster on each elytron consists of five strong punctures ; 

 the anterior discal puncture is about a fifth the length of the 

 elytron distant from the base.

CaNTHYDRUS BOVILLiE, Sp.UOV. 



Ovalis ; convexus ; posterius attenuatus ; nitidus ; niger, capite 

 anterius prothoraceque ad angulos anticos rufo-testaceis ', elytris 

 gutta transversa pone medium testacea, punctis sparsis sat con- 

 spicuis ; antennis testaceis ; pedibus rufis, posterioribus magis 

 obscuris. [Long. If, lat. 4 line. 



This species must be very near C. yuttula, Aube (from Mada- 

 gascar and Mauritius), but difiers apparently in having the red 

 mark on each elytron in the form of a somewhat irregular trans- 

 verse line, rather than of a round spot. 



Northern Territory of S. Australia ; taken by Mrs. Bovill and 

 dedicated to that lady.
