364 DESCRIPTIONS OP NEW SPECIES OF ACSTR.\LIAN COLEOPTERA, 



narrowly margined. Elytra with outlines continuous with those of prothorax, 

 widest at about basal third. Abdomen with coxal lines enclosing a distinct plate 

 on each side. Length, 1.75 mm. 



Hab. — New South Wales: Tamworth, Clarence River (A. M. Lea). 



Much the size and shape of E. vulneratus, but upper surface entirely black 

 except for the tips of elytra. Under a hand-lens the prothorax and elytra ap- 

 pear to be impunetate. 



Var. ?. Two specimens from the Nepean River (A. J. Coates), and Clar- 

 ence River (Lea), are possibly varieties of this species, they are of a livid-brown 

 colour with a large infuscate blotch on the elytra, and another on the metasternum, 

 both blotches quite conspicuous, although not sharply limited. 



DiPHYLLUS flavoxotatus, n. sp. 



Black, apical third of elytra and six spots across the middle flavous, legs, 

 antennae, and palpi flavo-testaceous. Densely clothed with short, suberect 

 pubescence, varying in colour with the derm. 



Head with small and crowded punctures. Antennae scarcely passing base 

 of prothorax; club two-jointed. Prothorax more than thrice as wide as long, 

 with a sharply defined stria near each side, and a less distinct one near it ; punc- 

 tures much as on head, except on sides, where they are somewhat larger. Elytra 

 with outlines continuous with those of prothorax; with regular rows of punc- 

 tures, fairly large at base, becoming smaller posteriorly; interstices with small, 

 partially concealed punctures. Length, 2 mm. 



Hab. — New South Wales: Ourimbah (A. M. Lea). Unique. 



An evenly elliptic species, shorter and more compact than D. ornatellus, and 

 elytral markings very different; the spots across the middle are not in a straight 

 line, but so placed that the median one on each elytron is slightly posterior to 

 the others; the pale apical portion is triangularly advanced on the suture. 



DiPLOCOELDS XANTHORRHOEAE, n. sp. 



Reddish-brown or castaneous, appendages not much paler. Densely clothed 

 with short, depressed, greyish pubescence, the upper surface in addition with 

 rows of short, semi-erect setae. 



Head with small and dense punctures. Antennae short, club three-jointed. 

 Prothorax slightly more than twice as wide as long, sides gently rounded, front 

 angles scarcely produced, with (excluding the margins) ten slightly elevated, 

 parallel lines, of which the four median ones are, except for their clothing, scarcely 

 traceable; punctures much as on head, but slightly larger towards sides. Elytra 

 parallel-sided to near apex, the width of widest part of prothorax; with regular 

 rows of punctures of moderate size, becoming smaller towards suture; interstices 

 with small punctures. Length, 2.75-3.25 mm. 



Hab. — Western Australia: Swan River, Darling Ranges; New South Wales: 

 Sydney; Tasmania: Huon River (A. M. Lea). 



The species may be taken at the bases of the leaves of several species of 

 Xanthorrh^ea. It is allied to D. opaeior (specimens of which have also been 

 taken on spiecies of Xanthorrhoea) , but is larger, paler, and the prothoracic lines 

 of clothing are much more evident; D. punctattis has the prothorax with much 

 coarser punctures and lines of pubescence scarcely evident, although with distinct 

 grooves; D. lattis is wider, with coarser punctures, etc.; D. decemlineatits has 

 median line of prothorax distinct, and elj^tra not parallel-sided; D. dilataticollis
