This species is near J/, communis, AVaterh., but is narrower 



and more elongate, and with markings so different that even if 



the discovery of intermediate forms should bring the two together 



it would be convenient to call it by a distinctive name. The 



silvery markings of the elytra are extremely sharply defined and 



conspicuous, consisting of a short narrow vitta on the front part 



of the suture, and on each elytron the following : — A short wide 



vitta running hindward from the middle of the base, a semilunar 



spot (its convex side forward) close in front of the middle, and a 



round spot distant from the suture considerably in front of the 



apex. The markings differ from tliose of communis in there 



being no isolated spot behind the base, in a large semilunar spot 



taking the place of the two small spots in front of the middle, 



and in the hindmost spot being larger, rounder, not nearly so 



close to the suture, and not quite so near the apex. This is not 



the " var. ?" of communis from Sydney mentioned by Mr. 



Waterhouse (Tr. E. S., 1878, p. 231). 



N.S. Wales ; near Sydney. 



31. Bnldiensis, Blackb. (Tr. R. Soc. S.A., 1891, p. 341). I 

 have taken specimens of a Mordella near Sydney, and also on 

 the Blue Mountain Range, which I cannot separate from this 

 Victorian species except by their very small size (long., 11.). I 

 suspect, however, that they represent a distinct species, especially 

 as some examples have the antennae and front legs decidedly 

 rufescent — probably a sexual character which I find scarcely 

 marked in Bakliensis.
