544 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



feebly punctate. Leg>i long; femora, especially the anterior, 

 thickened; tarsi simple. Length to apex of elytra 2^, of abdomen 

 5^ mm. 



^a6._Windsor, N.S.W. 



Numerous specimens obtained during a flood in the Hawkes- 

 bury River. This species very strongly resembles olivaceus, 

 Macleay, from which, however, its black palpi will at once serve 

 to distinguish it, that species (as noted by M. Fauvel) having pale 

 palpi; it also differs in the margining of the abdominal segments. 

 My specimens were compared with all the t3'pes of Macleay's 

 Gayndah Steni, so that I can be certain that the species was not 

 described by.him. From the description of atrovirens, Fauvel, 

 it differs in colour and puncturation, and M. Fauvel could scarcely 

 have avoided mentioning the loni; and distinct abdominal 

 clothing. 



Stbnus ianthinipennis, n.sp. 



Shining, finely pubescent. Black; elytra violet, abdomen with 

 a violet gloss; legs j^ellow, apical half of femora, apex of tibise and 

 tarsi infuscate; antenme pale, apical joints infuscate; palpi very 

 pale. 



//ead finely punctate ; a longitudinal excavation in middle, 

 carinate on each side behind antennte. Antennas extending 

 almost to intermediate cox?e. Prothorax slightly wider at base 

 than at apex, finely punctate, base and apex wrinkled. Elytra, 

 slightly longer than prothorax, densely and rather strongly 

 punctate, apsx widely emarginate. Abdomen with five basal 

 segments strongly margined, almost impunctate. Leys long; tarsi

//„6.— Upper Ord River, E. Kimberley, W.A. (Mr. R. Helms). 



In build much^resembling cupreipennis, Macleay, but, besides 

 colour, differs in having the head less excavated between the eyes, 

 and the el3^tral puncturation denser and less coarse. Mr. Helms 

 obtained numerous specimens.
