Rah.— New South Wales: C'ooma district (Dr. Black- 

 burn). 



Dr. E. W. Ferguson has kindly given me a specimen 

 (female) taken by the son of the late Canon Blackburn, which 

 evidently differs from its allies as follows : — From B. koscius- 

 koanus, Cart, (its nearest ally), in wider and more depressed 

 form, more opaque colour, finer punctures on head and thorax, 

 the lateral border of the latter much thicker, anterior angles 

 wider and less acute at apex; from B. reticulatus, Pasc, it 

 differs more widely in its finer punctuation of head and thorax, 

 much wider but less reflected lateral border, and in the less 

 raised sculpture (both costae and reticulation) of the elytra; 

 from B. ovensensis, Cart., in its non-dentate posterior angles, 

 inter multa alia. Type in author's collection. 



Promethis opaca, n. sp. 



S . Elongate-parallel ; opaque-black, apical half of fore 

 tibiae and under-side of all tarsi clothed with red tomentum, 

 antennae and palpi reddish. 



Head coarsely, unevenly punctate, the punctures largest 

 and less close between the eyes, more finely punctured towards 

 the neck; canthus strongly raised and subcornute, making a 

 distinct angle with the sides of epistoma; antennas as in P. 

 angulata, Erichs. Prothorax 5x6 mm., considerably widest 

 in front; apex bisinuate, produced in middle; anterior angles 

 forming a rounded lobe, renexed at border, more produced 

 forward and outward than in P. angulata; sides angulately nar- 

 rowed behind these, again narrowed before the widely obtuse 

 posterior angles, these not at all produced ; base bisinuate, with 

 raised lateral and basal border, the former thickened at the 

 anterior angles, obsolete on apex, the latter coarsely punctate ; 

 disc coarsely, unevenly, but in general rather closely punctate, 

 the punctures round and deep at centre, the sculpture more 

 obscure and rugose towards sides, medial line wide and deep 

 throughout. Scutellum semi-circular, coarsely punctate. 

 Elytra wider than prothorax at base and two and a half times 

 as long; sides parallel, more convex than in P. angulata; 

 punctate sulcate, with ten rows (including a short scutellary 

 and the extreme lateral row) of large punctures placed in 

 moderately deep sulci ; intervals crenulate and strongly raised, 

 under a microscope seen to be minutely punctured and 

 shagreened. Mentum fringed, submentum very rugose (sub- 

 pustulose), sternum punctate and finely rugose, anterior coxae 

 covered with short reddish hair, three anterior segments of 

 abdomen rather closely covered with large round punctures, 

 the apical segments finely punctate; legs long, the anterior
