S. Skusei, sp. nov. Tota lete cerulea certo adspectu viridi- 
micans, elytris antice ad latera et postice ante apicem trans- 
versim flavis exceptis ; capite longitudinaliter concavo sat 
crebre sat fortiter punctulato ; prothorace quam longiori (et 
postice quam antice) paullo plus quam dimidio latiori, basin 
versus in medio fortiter minus crebre punctulato (hine 
antrorsum et latera versus gradatim magis crebre magis 
rugulose, antrorsum magis subtiliter punctulato ; prothorace 
ut S. S-spilote, Saund., sculpturato), lateribus fere a basi ad 
apicem arcuatim convergentibus, basi fortiter bisinuata, 
angulis posticis acutis; elytris punctulato-striatis, basi 
antrorsum late sat fortiter arcuatim prominulis, apice 
oblique emarginatis, intus breviter extus fortiter spinosis, 
lateribus pone humeros late minus fortiter dilatatis postice 
denticulatis, interstitiis sparsim minus subtiliter punctulatis, 
antice suturam versus subplanis, latera apicemque versus sat 
convexis ; corpore subtus sat crebre sat fortiter punctulato, 
breviter sparsim albido-pubescenti. Long., 63 1. ; lat., 24 1. 
A very pretty and distinct species, entirely (except the yellow 
parts of the elytra) of a rich blue colour with greenish reflections 
in certain lights. The elytra are more easily described if the 
yellow be regarded asthe ground colour. The blue then appearse 
asa very wide common sutural vitta (about as wide as each of th 
yellow lateral spaces) extending from the base to slightly beyond 
the middle of the length, where it merges in a straight fascia of 
the same colour (both margins of which, however, are sinuous), the 
front of which is a little behind the middle of the elytra; each 
elytron also bears a small blue spot occupying its inner apex.

S. hostilis, sp. nov. Nigro-enea, elytris flavo-brunneis nigro- 
trifasciatis, externe rubro marginatis; fasciis in sutura 
conjunctis ;  prothorace quam elytra multo angustiori 
creberrime subtilius (basin mediam versus sparsius magis 
fortiter) punctulato ; elytris punctulato-striatis, interstitiis 
crebre punctulatis antice suturam versus sat planis latera 
apicemque versus convexis, ad apicem singulatim trispinosis; 
corpore subtus dense sat longe piloso. Long., 54 1. ;

The base of the elytra, which is narrowly black, is very 
distinctly wider than the base of the prothorax, and is distinctly 
and minutely dentiform at its humeral angles; it is widely 
arcuately and somewhat evenly arched forward. The front fascia 
is a little behind the base and is straight, its lateral apices a 
littie produced forward, its middle with a small triangular projec- 
tion nearly touching the scutellum ; it does not reach the lateral
