330. S. humeralis. Pering. 



I should have added to the orginal description that the outer sides 

 of the prothorax and of the elytra have a conspicuous white band. 

 Recorded from Darnaraland only. 



331. S. opalinus. spec. nov. 



Niger, squamis opalinis dense tectus ; prothorace antice angustato 

 lateribus hand rotundatis posticeque acute dentatis ; elytris elongatis 

 striato-punctatis, humeris in dentem parvum productis. 



Long. 9, lat. 3| mm . 



Shape and size of S. humeralis, black and totally covered with 

 opaline scales and thus distinguished from the former ; the prothorax 

 is also more elongated, narrowed in front, but not behind, with the 

 postical angles a little more acute ; elytra elongated, a little ampliated 

 past the middle, narrowed behind, very convex and narrowly striated 

 with the striae punctured. 



Peuenoderus. Gen. nov. near Siderodactylus. 



Head and antennae of Siderodactylus • prothorax trapeziform with 

 the outer posterior angles acute and very strongly developed in a 

 conical tubercle in the male ; elytra strangulated at the base and 

 narrower than the base of the prothorax, dilated a little past the 

 middle, very convex and acuminated behind ; anterior tibiae strongly 

 serrated in both sexes, male with a strong tooth at the apex of the 

 anterior femora. 



Judging from the description only, and also from Lacordaire's 

 remarks, Gener. d. Coleopt. Vol. 6. p. 103, the Siderodactylus denti- 

 collis, Thorns., will have to be included in this genus. 



332. P. distinctus. spec. nov. 



Mas. Niger, squamis sparsis aurantiaco-opalinis tectus ; capite 

 prothoraceque granuloso punctatis, hoc transverso, elevato, angulis 

 posticis dilatatis, sub-fasciculatis acuteque dentatis; elytris antice 

 augustatis, post medium sub-dilatatis, convexis, striato-punctatis, 

 squamis aurantiacis lateraliter balteatis. 



Femina a mare differt prothorace sub-rotundato femoribusque 

 anticis haud dent Mis. 



Long. 11-12^, lat. 3-3^ mm . 



B v lack, sparsely covered with golden, opaline scales, denser on the 

 outer sides of the elytra where they form a lateral band ; head faintly
