numerous long erect hairs on the upper surface (they are almost 

 wanting in heterodactyla and soror) and by the markedly stronger 

 and more asperate puncturation of its prothorax, and from soror 

 also by the much less strongly rounded sides of that segment. 

 The antennae of the male are very similar to those of the two 

 species just named but the female has the club of its antennae 

 only 5-jointed (in soror it is 6-jointed, — ^I do not know the female 

 of heterodactyla, but Germar implies that its antennal club is 7- 

 jointed). 



N.S. Wales. 

 R. morbillosa, sp. nov. R. Mussoni affinis. Minus elongata ; 

 supra breviter sparsim pubescens; testacea vel fusco-testacea;, 

 capita rugulose inaequaliter, prothorace fortiter vix crebre 

 (quam heterodactylce multo minus crebre), elytris rugulose 

 sat grosse, pygidio confertim aspere, punctulatis ; prothoracis 

 conformatione fere ut R. hirtuosce sed angulis posticis 

 rectis bene determinatis ; elytris subcostatis (fere ut 

 R. heterodactyloi). 

 Maris antennarum flabello elongate 5-articulato, flabelli arti- 

 culis 1° 2° que quam ceteri multo brevioribus (hoc quam ille 

 longiori ad apicem profunde emarginato). 

 Fem. latet. 



The club of the antennae in the male having only three long 

 joints at once separates this species from all its described con- 

 geners. In other respects it is very much like R. Mussoniy 

 Blackb., but differs inter alia in its prothorax considerably more 

 closely, and its elytra evidently more coarsely, punctured.
