another in length, -witli the last three or four somewhat thicker 

 than those preceding them. Femora unarmed. 



This species and the preceding one differ from nearly all the 

 Australian species of Rhyj^nrida in having the second joint of 

 the antennae less than half as long as the third. In this respect 

 they resemble certain Indo-Malayan species, and agree with those 

 •of the ffenus Limlinia, Lefcv. 



90. Demotina lateralis, Gahan, sp.n. 



Parva, tcstacca, setis decumbentibus fulvis sat dense vestita ; 

 ■capite supra linea media glabra a clypeo ad occiput extensa, 

 clypeo glabro transverso sub-semilunare ; prothorace transverso, 

 lateribus rotundatis, margine omnino deleta ; elytris crebre sat 

 fortiter punctatis, disco paullo convexo, lateribus valde deflexis, 

 costa utrinque inter discum latusque ; antennis basin elytrorum 

 vix siiperantibus, articulis 1°, 2° que crassis, subovalibus, 3° 

 angusto, cylindrico, quani 2° baud longiore, articulis 7° ad 11"™ 

 paullo dilatatis. 



Long. 2"5 mm. 



Colour testaceous, with the middle of thoracic disk and spots 

 on the elytra dark brown ; the whole rather thickly covered with 

 decumbent tawny setae. Prothorax broader than long, slightly 

 rounded at the sides, which are wholly without a sharp carinate 

 margin. Elytra thickly and rather strongly punctured, abruptly 

 deflexed at the sides ; the latter being vertical and marked off each 

 from the disk by a slightly projecting costa or line. 



In the abruptly deflexed and vertical sides of the elytra this 

 species differs from all others belonging to the genus Demotina. 



In general appearance it most resembles D. howringi, Paly, 

 a species occurring in Hongkong, Formosa, and Chusan ; and it is, 

 perhaps, more nearly allied to this than to any other described 

 species. The genus Demotina has a distribution ranging from 

 ■China and Japan to New Guinea. 



91. Scelodonta nitidula, Paly, var. ? 



One example, taken on Phosphate Hill; November, 1897. 



This example may possibly represent a distinct species ; it differs 

 from nitidula in having the elytra of a uniform dark coppery- 

 brown colour, slightly tinged with metallic green ; smoother on 

 the middle of the disk ; and furnished with shorter setae. 

 S. nitidula, Paly, occurs in Pomeo, Sumatra, Java, Malacca, and 

 in North and South India. In every example I have seen there 

 are two or more spots of a purplish or steel-blue colour on each 

 elytron ; but these spots are sometimes very small and faint.
