288 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



terminates in a moderately large spot, at about a third from the 

 apex a moderately large irregular transverse spot. Meso-, sides 

 and middle of metasternum, and abdominal segments, and ba.se of 

 aculeus with griseous pubescence. 



Scutellum with a shallow depression at its base. Aculeus 

 rather long, very broad at the base, suddenly triangularly lessened, 

 apical half almost parallel-sided, truncate at apex. Posterior 

 spurs unequal, the longest half as long as first tarsal joint, and 

 fully twice as long as its fellow. Length 4J-5, width 14. 



Hah. — North West Australia (Macleay Museum). 



A broad rol^ust species with a very broad head. I have 

 examined seven specimens, but they have all been very dirty; 

 the species is very distinct, and an examination of fresh specimens 

 would probably discover additional markings. 



MoRDELLA AUSTRALis, Boisd. (?); Mast. Cat. Sp. No. 4314. 



Black; muzzle, base of antennae, anterior legs and intermediate 

 femora testaceous. Head with greyish pubescence at the base on 

 each side appearing almost bare. Prothorax with silvery pubes- 

 cence, with a median and two lateral vittse. Elytra at the base 

 with four stripes, one on each side of the suture projecting out- 

 wardl}", the others midway between suture and sides; a narrow 

 zigzag fascia at the middle composed of three Vs, the central one 

 somewhat irregular; near the apex a narrow fascia — not always 

 complete. Meso-, sides and apex of metasternum, sides and 

 middle of abdominal segments, and base of aculeus with greyish 

 pubescence. 



Aculeus moderate, suddenly lessened at about its middle, apex 

 pointed. Posterior spurs unequal, the longest not quite half as 

 long as the first tarsal joint. Length 2|-3J, width 4-14 mm. 



The above is the description of a widely distributed species 

 which I take to be M. australis; it is the species labelled by the 

 late Sir W. Macleay as such in his own museum (though not the 

 species he named as such from Gayndah). Boisduval's description 

 is very brief (12 words), certainl}^ insufficient for its positive 

 identification.
