and more evenly tlian is usual in the genus ; the whole surface 

 being minutely coriaceous gives it a dull appearance. It is 

 almost entirely concolorous, except that the thorax is a little 

 the darkest part. The head and thorax are rather coarsely and 

 closely punctured ; the latter is strongly convex in front. Im- 

 mediately behind the front the lateral margins are curved 

 pretty strongly inwards for a short distance, and then curve 

 outwards very slightly to the base, so that their outline is 

 concave, the widest part being the anterior margin. The sur- 

 face of the thorax is a little uneven, the most evident depression 

 being elongate, wide and shallow, and occupying the hinder part 

 of the disc. Between the suture and what would be the fourth 

 interstice if the puncturation ran evenly in rows there is no 

 distinct puncturation at all. This fourth interstice is slightly 

 elevated and continuously distinct, except at the extreme base 

 and apex ; then follow five rows of punctures, clearly traceable 

 under a good lens, the interstices between the second and third 

 and between the fourth and fifth of them being similar to that 

 which precedes them. Hence to the lateral margin the sculpture 

 becomes quite faint and confused again, but there are indica- 

 tions of two obscure costae near the margin. The sculpture is 

 so slight that under a lens of only moderate power none of it 

 is noticeable except the three slender raised interstices. The 

 anterior coxae are about as far apart as in L. hrunneus, and the 

 front part of the prosternum is evenly convex as in that 

 species. 



Larger than L. hrunneus^ much less shining, differently 

 coloured, the prothorax more coarsely punctured, and more 

 noticeably at its widest in front ; the elytra much more 

 obscurely punctured, and with the raised interstices very much 

 more conspicuous. 



A single example occurred at Port Lincoln. 

 L.parallelocollis, ^^.noY. Sat nitidus ; elongatus ; rufo-piceus; 

 prothoracis lateribus subparallelis, sub-crenulatis ; elytris 

 subtiliter striato-punctatis ; inters titiis vix convexis.

More shining and less pubescent than L. costatus. Head and 

 prothorax very strongly but not closely punctured. The latter 

 transverse, its front margin strongly convex, its sides nearly 

 straight, the hinder portion of its disc widely flattened. The 

 elytra are distinctly striated, the striae almost strongly punc- 

 tured, the sculpture best defined on the disc, where and towards 

 the apex the interstices have a tendency to be convex. The 

 anterior coxae are separated a little more decidedly than in 

 L. hrunneus. The anterior part of the prosternum is widely 

 flattened in the middle. In some specimens (perhaps males)
