rugose anteriorly. Scute/him widely triangular. Elyti a as wide 

 as protliorax at base, slioulders subaiigulate but rounded, sides 

 parallel to half-way, widely rountled at apex, convexity strongly 

 inereasing posteriorly, apical declivity abrupt, margins widely 

 hdiizontal at shoulders, soon narx'owed and becoming deflexed 

 apically; each elytron with the suture carinate throughout and 

 with four strongly raised equidistant costte, the suture less raised 

 than tlie adjacent costae; the first costa? parallel to suture, diverg- 

 ing at extreme base and joining the fourth costje near aj^ex; 

 second and thirtl costje con\'erging at base and terminating in 

 diminishing nodules independently towards apex (the third 

 longer than second) ; the fourth interrupted before half-way, 

 then a line of more or less elongate nodules at the junction of 

 disc with margins, the third costae only slightly interrupted : 

 on each side of suture and costae are rows of large punctures ; 

 those outside the fourth costae larger than the rest ; the inter- 

 vals between the costae also irregularly impressed with smaller, 

 shallower punctures than the preceding, and less obvious on 

 account of the short, yellow, hairy derm on the elytra. 

 AJxlomeii punctate and covered with a similar but shorter 

 clothing than that on the upper surface. Epvphune nearly 

 smooth, but with large, round, irregularly scattered punctures. 

 Femora and tihicf covered like the abdomen with hairy derm. 

 Procter nu HI raised, scarcely carinate, with the produced por- 

 tion received into the mesosternuni in a wide U-shaped re- 

 ceptacle. Anterior tibiae with a short blunt spine at apex.

Specimens of the above occur in the Macleay Mviseum ; and 

 two specimens have been given me by Mr. Masters. It differs 

 markedly from all hitherto described species with costate 

 elytra by its distinct chocolate colour, caused by the yellowish 

 derm on a darker ground. This derm covers the whole insect, 

 except the disc of pronotum. Its nearest ally is S. hicarinatua 

 Champ., which has only three costae on each elytron, is less 

 convex than, and differs in colour from N. novemrostafux.
