DiflFers from longirostris in the rostrum being distinctly 

 sliorter than the elytra ; prothorax less dilated to the base, 

 and with three conspicuous lines of white scales, &c. The 

 resemblance to species of Idotasia is much less pronounced, 

 but the scrobes, lateral sulci, and legs convince me that the 

 species should be g^enerically associated with longirostris. 

 On the side of each elytron there is a row of punctures in a 

 stria, then three seriate rows, and then rows in regular stripe 

 to the suture. 



There are three specimens of this species in the British 

 Museum from the Richmond River, but they have been 

 I'ather dirt}'^ and the prothoracic strip(>s from one have been 

 abraded, and partially so from the others. 



Phaunceus medio albus, sp. n. 



Black, shining ; parts of antennae and of tarsi obscurely 

 diluted with red. White scales forming a continuous 

 median line on prothorax, several spots on elytra, dense on 

 middle of sterna and of basal segment of ab lomeu, and 

 irregularly distributed on legs. 



Head with dense, clearly defined punctures. Rostrum 

 moderately thin, slightly longer than prothorax, moderately 

 curved, with fairly large punctures, more or less seriate in 

 arrangement behind antennae. Thesa inserted about one- 

 third from apex of rostrum ; first joint of funicle as long as 

 second and third combined. Prothorax strongly convex, 

 distinctly longer than wide, sides rather strongly rounded, 

 with dense and rather coarse punctures. Elytra subcordate, 

 almost twice the width of base of prothorax, with rows of 

 deep punctures in narrow stripe, the seventh and eighth rows 

 not in string. Legs long, four front tibiae strongly curved. 



Length 2{-2\ mm. 



Hab. Queensland : Cairns, Endeavour River {Macleay 

 Museum) . 



In build, except that it is smaller, rather close to the 

 preceding species, but clothing different and prothoracic 

 punctures distinctly larger. The wliite scales appear to be 

 rather easily abraded, as the median line of the prothorax is 

 sometimes traceable only at its ends ; on each elytron there 

 are normally three spots : two about middle, on the second 

 and third interstices, and one at apex, but occasionally they 

 arc all absent.
