the lateral band of a silvery-white colour. The upper maro-in 

 of this band rises from the front extremity of the lateral marifin 

 and runs obliquely hindward, and towards the suture to a point 

 immediately behind the black humeral callus, whence it runs in a 

 straight line (parallel with the suture) to the apex ; it is marked 

 with about a dozen sharply-defined little indentations, each of 

 which is occupied by a granule or large puncture. Several 

 species previously described resemble this one more or less closely, 

 especially in the combination of a prothorax devoid of strong- 

 transverse folds with elytra ornamented laterally with snowy- 

 white pubescence. I have in my collection examples of nearly 

 all of them, but as in the instance of one or two there is a pos- 

 sible doubt of their being correctly identified, I will content 

 myself with mentioning the following characters in which (accord- 

 ing to their description) they ditter inter alia' from the present 

 insect. S. Bathursti, Pasc, has two small central tubercles on 

 the prothorax, decipienn, Pasc, is of a greyish-green colour and 

 has a small triangular dark spot behind each eye, derasus, Pasc, 

 has SIX feeble tubercles on tlie prothorax, Duboulayi, Pasc, has 

 tlie lateral snowy pubescence of the elytra in the form of an 

 oblong spot, iliacus, Pasc, is a smaller insect of dark olive-green 

 colour, lateralis, Pasc, has the general pubescence of the\ead 

 fulvous.

C. australica, sp. no v. Elongata j parallela ; nitida; convexa ; 



:enea, labro palpis antennis pedibus elytrorumque epipleuris 



rufescentibus ; capito lato minus convexo, sat crebre sat

oculis obsoletissime nee subtiliter granulatis : prothorace 



transversini subquadrato, quam elytra parum angustiori,

This species is clearly, T think, a member of 'Dr. Baly's genus 



tarystea, which Dr. Chapuis regards as inseparable fi-om 



thnjsomela. If the eyes of all the previously described species 



are like those of the present one, I think Dr. Baly's genus may
