-582 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



•such an attempt would probaVjly cause even greater confusion. 

 The following species are all very distinct; there are many others 

 an my collection which for the present must remain undescribed. 



Adelium regulare, n.sp. 



Bronzy-black, shining; head and prothorax less polished than 

 elytra, under surface and legs black, knees feebly tinged with red, 

 antennse blackish-brown with a feeble greenish reflection. 



Head regularly, finely but not densely punctate; frontal impres- 

 sions straight, deep, at sides touching longitudinal depressions; 

 Tertex with two shallow impressions, usually longitudinal or 

 slightly oblique, sometimes transverse or circular, occasionally 

 absent. Antennae passing base of prothorax, 3rd joint slightly 

 shorter than 4th-5th combined, 11th about once and one-half 

 longer than 10th and considerably wider. Prothorax not twice 

 as wide as long, finely and rather sparsel}'- punctate and without 

 larger punctures or fovese, but occasionally with very shallow 

 'depressions; apex shallowly emarginate, base feebly incurved; 

 ■sides regularly rounded both at apex and base, finely margined, 

 with or without a feeble median line. Elytra scarcely wider 

 than prothorax; striate-punctate, punctures regular, subquadrate, 

 not large; interstices regular, feebly convex, feebly and sparsely 

 punctate; epipleurse minutely and obsoletely punctate. Under 

 mrface sparsely and minutely punctate. Length 7, width 3^ ram. 



//a6.— Forest Reefs, N.S.W. 



This species somewhat resembles inconspicuiim, Blackburn, but 

 may be distinguished by its larger and more finely punctured 

 prothorax, sparser and finer puncturation of head and elycral 

 interstices, and different colour; from neopTiijta, Pascoe, it is still 

 more distinct. I have numerous sjDecimens. 



Adelium heterodoxum, n sp. 



Highly polished; head and prothorax of a dark blackish-green, 

 •elytra violet-bronze; abdomen black with a feeble greenish-bronze 

 reflection; legs with distinct greenish reflections; antennae piceous- 

 brown, basal joints darker. Abdomen and legs sparsely pubescent.
