■ COLEOPTERA.—LEA. 237 



Close to D. leai, but distinctly larger, less hairy, and as a result the punc- 

 tures appear more distinct and the derm shinier, with the median line of the 

 prothorax not traceable throughout, but represented by a short impression joining 

 the basal line. The setre on the elytra, when viewed from behind or in front, 

 are seen to be in regular lines, rows of longer ones on the interstices alternating 

 with somewhat shorter ones set in the seriate punctures. 



DIPLOCCELUS SERICEUS sp. nov. 



Blackish ; legs, antenna?, and palpi obscurely reddish. Densely clothed 

 with short, depressed, brownish or greyish sericeous pubescence; upper surface, 

 in addition, with dense, fairly long, erect, reddish seta?. 



Head' with fairly large but partially concealed punctures, a transverse 

 impressed line at base. Antenna? slightly passing base of prothorax ; club three- 

 jointed, apical joint almost as long as the two preceding combined. Prothorax 

 about twice as wide as long, sides strongly rounded, front angles produced, rest 

 of apex straight, with three deep somewhat curved lines on each side, a deeper 

 and somewhat sinuous line across base ; punctures minute, and more or less 

 concealed. Elytra v/ith sides gently rounded, widest at about basal third ; with 

 rows of fairly large, sub-oblong punctures, becoming much smaller and rounded 

 near suture; interstices with minute punctures. Length, 7-7-75 mm.

 Lea). — Type, /. 11788 in South Australian JMuseum ; cotype, C/2075 in Queens- 

 land IMuseum. 



About the size and shape of Z>. Icai, but with very different clothing; the 

 elytra have a curious mottled appearance, owing to numerous sericeous-looking 

 patches, which alter their positions with the point of view; the arrangement of 

 the elytral setse is much as on the preceding species, but the pubescence is 

 different, and the punctures are m_uch smaller; from the prothorax, owing to 

 the denser pubescence, they appear at first to be absent ; the transverse basal 

 line of the prothorax is also without a median projection. 



Vars. ? — Two other specimens, from Cairns, probably belong to this 

 species ; they have the seta? on the upper surface much denser than on the typical 

 form, scarcely half their length, and not at all seriate in arrangement; the 

 pubescence has a mottled appearance, but on one of them is even denser than on 

 the types, and on the other sparser, with the result that on one the derm appears 

 to be sub-opaque, and on the other more polished. 



DIPLOCIJLUS DILATATICOLLIS sp. nov. 



Dull reddish brown or castaneous, appendages slightly paler. Densely 

 clothed Avith short, depressed pubescence, denser and paler on under surface 

 than on upper, the latter in addition with lines of short, semi-erect seta?. 



Head with dense and rather small punctures ; a shallow depression on 

 each side of clypeus. Antenna? short; club three-jointed. Prothorax more than
