352 COLEOPTERA 



natus. Elytra convexa, subcordata ; epipleurce, latae, integrse. Pedes 

 tenuati ; tibiae cylindricae, apice breviter bispinosse. Coxm posticse sub- 

 approximatae. 



The head is slightly concave between the antennae ; the latter are 

 nearly free at the base, owing to the small size of the antennary orbits ; 

 for the same reason the eyes preserve their rounded outline. The 

 clypeus is rather narrowed anteriorly, and shows no trace of any line of 

 separation from the front. The tarsi are filiform, and the claw-joint is 

 nearly as long as the rest together, especially of the anterior pair. 



640. S, marginatUS, Pascoe ; Ann. Mag. Nat. Hist., September, 

 1875. ^- ovalis, fuscescens, squamis silaceis sat dense tectus ; antennis 

 articulo tertio quam secundo duplo longiore ; clava tomentosa ; pro- 

 thorace inaequato, apice bifido, angulis anticis acute productis, lateribus 

 explanatis ; scutello valde transverso, fusco ; elytris prothorace latioribus, 

 punctis parvis in seriebus irregularibus impressis, dorso tuberculis pluri- 

 mis instructis, marginibus explanatis, transversim sulcato-punctatis ; 

 pedibus albido variatim maculatis. 



Long., 5 lin. 



The exact habitat is unknown ; my specimens I owe to the kindness 

 of Major Parry. 



641. S. CrenatUS, n.s. Body uneven, fuscous, clothed with small 

 scale-like setae. Antennce scarcely as long as the head and thorax, 

 setose, club not well-defined, pubescent, the third joint quite twice the 

 length of the second. Head scarcely depressed, with moderately eleva- 

 ted antennal orbits ; eyes transverse, somewhat truncated in front and 

 behind ; its surface densely squamose. Thorax transverse, with expla- 

 nated sides ; apex emarginated, with an obtuse lobe at each side of the 

 central excision, and deeply sinuated towards the acute prominent 

 porrected front angles (they are not bent inwards as in S. viarginatus) ; 

 it is widest at the middle, where the sides are obtusely angulated, 

 sinuously narrowed in front and behind, with an uneven suface, the 

 anterior portion being depressed, so that the hinder part seems to be 

 rather abruptly elevated ; it is clothed, like the rest of the body, with 

 testaceous scales. Scutelliini large, very transverse. The elytra are 

 much broader than the thorax, convex, with explanated margins, rather 

 gradually declivous, and a good deal narrowed behind ; each elytron 

 bears a row of three tubercles, the smallest near the base, the largest, 

 laterally compressed, close to the posterior declivity, and other smaller 

 ones near them ; their anterior portion is irregularly and coarsely punc- 

 tured, the posterior more finely and regularly ; the lateral explanated 

 spaces are divided by transverse elevations into several large cavities 

 (eight or ten at each side), and the margins, as are those of the pro- 

 thorax, are finely crenated. Legs squamose. Underside rugulosely 

 sculptured and squamose. 



Length, 4-| lines. 



My specimen is from Capt. Hutton, who found it at Martyn's Bay, 

 on the west coast of Otago. The species differs from S. niarginatus in 

 the form of the thoracic angles, elytral sculpture, &c.
