•*254 NEW SPECIES OF AUSTRALIAN COLEOPTERA, II., 



Tibice straight, hind tarsi with 1st joint much longer than the 

 4th. Dimensions — £ 12 x 35 mm.; 2 14 x 4 mm. 



Hab.— Byron Bay, N.S.W. 



The £ is smaller, narrower, and more convex, especially as to 

 the pronotum. Antennae are relatively longer, hind tarsi shorter. 

 I have examined three specimens of this insect (one £, two 9)- 

 In colour and shape it is most like 0. Jacksoni (mihi), from which 

 it may be easily distinguished by size, shape of prothorax (much 

 more cordate than in 0. Jacksoni) and by the widely different 

 sculpture of the elytra, e.g., the sharp edge of the interstices, the 

 number of strise inter alia. The £ and one £ have been returned 

 to Mr. R. Helms, to whom 1 am indebted for the third specimen, 

 and who called my attention to this species. 



Possibly a new genus may hereafter be required for this 

 insect. The complete absence of any foliaceous margin to pro- 

 thorax prevents its inclusion in Cardiothorax, while it differs 

 structurally from the typical 0. Behri Germ., in its truncate base 

 to pronotum and in its less elevated mesosternum. 



Daedrosis hirsuta, n.sp. (Plate xx., fig. 14). 



Elongate-ovate, hirsute; head, pronotum, elytra and legs dark 

 TDronze; tarsi and antennae dark castaneous; underside bronze- 

 black. 



Head very similar to that of D. crenato-striata Bates, but the 

 division between front and epistoma more strongly marked; in 

 other words, the irregular frontal depression is deeper, and the 

 punctures thereon are deeper and more widely separated. Pro- 

 thorax more widely rounded than in D. crenato-striata, as wide 

 -as long, widest about the middle and nearly equally obtusely 

 rounded before and behind, the angles in both cases obsolete. 

 The disc is even more deeply punctate, the punctures with less 

 tendency to coalesce (to become rugose) than in the above. 

 Medial line indicated by a slight depression, with fewer punc- 

 tures than the rest of disc, widest towards base. On the disc, 

 which is more convex than D. crenato-striata, are two irregular 

 depressions on each lobe, the larger about the centre, the smaller 

 -one directly in front of this. Elytra punctate-striate, stria?
