the elytral strize and also on the interstices are much stronger, 
the interstices are very much more convex ; the underside is of a 
bright blue colour, and the pectoral excavation (receiving the 
prosternal process) is strongly elevated ; the pubescence of the 
underside and legs is very thin and inconspicuous. The external 
angle of the base of the elytra is strongly defined and directed 
outward. The apical spot on the elytra is not connected on the 
suture with the transverse fascia.

S. Macleay2, sp. nov. Sat lata; subtus modice albido-pubescens ; 
obscure viridis ; elytris testaceis, basi anguste viridi, sutura 
late viridi (colore viridi pone scutellum dilatato, mox pone 
medium fasciam externe violaceam ad latera emittenti, 
paullo ante apicem in macula magna transversa dilatato, 
circa apicem recurvato), macula sat parva violacea pone 
humeros oblique posita; capite prothoraceque creberrime 
subtilius punctulatis; illo inter oculos longitudinaliter 
concavo ; hoc quam longiori vix dimidio (postice quam antice 
fere duplo) latiori, lateribus a basi ad apicem rotundatim 
convergentibus, basi media angulatim lobata, angulis posticis 
acutis; elytris striatis (striis subtiliter punctulatis), basi 
antrorsum late trisinuatim minus fortiter prominulis, apice 
oblique emarginatis et bidentatis, dentibus externis majoribus, 
lateribus pone humeros modice dilatatis, interstitiis fere ut 
S. sternalis set multo magis crebre punctnlgeee corpore 
subtus confertim punctulato. Long., 61; lat., 221 
The colour of the markings on the elytra is peculiar, the base 
and extreme suture being green, all the other markings deep 
violet. The markings on the elytra are almost exactly (save that 
the post-humeral spot and the post-scutellar dilatation are smaller) 
as depicted in the figure of S. awdax, Saund. (Ins. Saund., IIL, 
1, t. 1, fig. 7), which, however, is a very different insect in other 
respects. The base of the elytra is of the same width as the base 
of the prothorax, their humeral angle is acute, but scarcely 
dentiform. The puncturation of the head and prothorax i is as In 
S. ocellagera, L. & G. Perhaps near S. Muasteri, Macl., which, 
however, is described as a smaller species of a brassy or bluish-black 
colour, the anterior spots on the elytra as adjoining the scutellum, 
the apices of the elytra strongly bispinose and not marked with 
dark colour, &c. The description of puncturation, &c.,is not definite 
enough for comparison. Also near cyamnicollis, Boisd., differing 
inter alia by its prothorax at the widest across the base and 
more closely punctulate.
