at apex, part of abdomen, legs (basal parts of tibiae excepted), 

 palpi, and most of anennae. 



Three specimens from Adelaide River (in the British 

 Museum) belong to this species : one is coloured exactly as the 

 type, except that a greater portion of the apex of the elytra 

 is pale ; on the other two the apex is as on the type, but the 

 basal markings are reduced to an elongate spot on each 

 shoulder, where the black is diluted to red. 



Rhyparida militaris, n. sp. 

 PI. vi., fig. 43. 



Reddish-brown, palpi and parts of antennae and legs 

 paler; elytra conspicuously striped. 



Head shagreened and minutely punctate; with a narrow, 

 deep, medio-frontal impression, connected with clypeal suture ; 

 clypeus with fairly dense and rather large punctures. Eyes 

 moderately large and widely separated. Prothorax across 

 middle almost twice the median length, all angles armed ; with 

 fairly dense and rather small, but clearly-defined punctures, 

 disappearing from close to all the margins. Elytra of the same 

 shape as in the preceding species, and with similar but slightly 

 smaller punctures. Flanks of 'prosternum conspicuously 

 striated about base, but feebly elsewhere. Femora edentate. 

 Length, 4 mm. 



Z^a 6.— Melville Island (W. D. Dodd). Type (unique), 

 I. 3121. 



In sculpture rather close to the preceding species, but 

 strikingly different in colours. I have not been able to see 

 the claws clearly. The flanks of the prosternum are conspicu- 

 ously striated about the base, but the major portion of each 

 side is shining and smooth, about one-fourth from each margin 

 to the coxa there are fine striae that are traceable to the apex, 

 but discernible practically only by the surface appearing 

 opaque. On each elytron the suture and margin, and the 

 fourth, sixth, and eighth interstices are conspicuously darker 

 than the others, these being almost flavous. 



Rhyparida polymorpha, n. sp. 

 PI. vi., figs. 44 and 45. 

 Black, some parts reddish, or reddish some parts black, or 

 reddish, parts of antennae infuscated. 



Head with fairly dense but small punctures about base, 

 becoming very feeble in front ; with a narrow medio-frontal 

 impression, connected with an irregular clypeal suture ; clypeus 

 with dense and rather coarse punctures. Eyes large, promi- 

 nent, and widely separated. Prothorax about twice as wide
