4. S. equinociialis, n. sp. 
Oblongo-ovalis, subparallela, leviter canaliculata, flava, nigro- 
ornata: caput nigrum apparet, labro etiamque in fronte 
macula insulata flavis; ad frontem fovea est media obsoleta, 
a basi usque ad antennarum basin; thorax transversus est, 
latitudine (ad medium) vix duplo longitudine majori; apex 
modice excavatus est, basis transversa, Jatera rotundata et 
haud apicem versus constricta; sculptura ut in specie prace- 
denti; undiqne laté depressus (ad medium fovea longitu- 
dinalis apparet); quoad colorem niger, lateribus undique 
laté etiamque vitta media flavis; scutedlum rotundato-triangu- 
lare, pube densa flava vestitum; elylra subparallela, thorace 
paululum Jatiora, apice rotundata (elytrorum apicibus vix 
dehiscentibus); juxta suturam carina haud apicem attingens 
patet, et altera a humeris vix ad medium extendit; quoad 
colorem fascia media nigra (ad basin vitté communi nigra 
juncta) etiamque apex laté niger elytra flava ornant; an- 
tenne robust, nigre ; pedes nigri, femorum basibus fusco- 
adumbratis ; abdomen corpusque subtus nigra. 
Long. corp. lin. 4; Jat. lin. 12. 
This beautiful species is allied to S. vicina, but is readily 
separated from it by its different sculpture, as well as by its 
pattern of colours. I have a single specimen in my Collection 
received from Columbia. 
5. S. venusta, n. sp. 
Oblengo-ovalis, subparallela, leviter costata, nigra, flavo-ornata ; 
caput ad medium foveolatum, nigrum; thorax transversus, 
latitudine vix duplo longitudinem superans, lateribus ro- 
tundatis, flavus, vittis duabus latis nigris mediis, parallelis ; 
scutellum semicirculare, nigro-fuscum ; elytra subparallela, 
elongata, leviter costata, nigra, fascia media ineequaliter mar- 
ginata, macula ad humeros longitudinali, alteraque apud scu- 
tellum minori, communi, flavis: corpus subtus, pedes et an- 
tenne nigri. 
Long. corp. lin. 33; lat. lin. 14. 
Of the same size and generally of the same pattern as S. equi- 
noctialis ; it differs however from that species by its less distinctly 
marked costa on the elytra, as well as by the difference of 
details of coloration: the two thoracic vitte are broader, the 
humeral flavous markings are much smaller, and the flavous 
fascia of the elytra is medial, and not, as in S, @quinoctialis, post-
