Genus Schematiza. 261 
tertiam elytrorum nigrescit ; antenne satis elongate et late, 
nigree ; ita quoque pedes et corpus inferius. 
Long. corp. lin. 6—53 ; lat. lin. 3—23. 
It is probable that 8. Lycoides is subject to some variation of 
pattern in the anterior part of the elytra: in one of the examples 
before me there is a trace of dark colouring between the 2nd and 3rd 
costa, and also again near the margination; even, however, should 
the anterior part be in any examples entirely dark, the difference 
of the form of the elytra, which are more parallel, or rather less 
broadly rounded behind the middle, will abundantly separate this 
from the following species. 
In the Collections of Mr. Baly and the Rev. H. Clark. The 
insect is taken in Brazil. 
2. S. amplicornis, n. sp. 
Lata, undique quinque-costata, subtiliter granulata, nigra, fascia 
flava media: caput subtiliter granulatum, nigrum; thorax de- 
pressus, laté transversus, antice modice excavatus, ad latera 
rotundatus, et apicem versus contractus; margo basalis trans- 
versus est; apud latera thorax longitudinaliter laté et haud 
profundé excavatur, hac fovea undique flava est, disco medio 
corrugato et nigro ; scuteldum triangulare est, colore nigrum; 
elytra versus medium rotundato-ampliata, ad apicem rotundata 
(vix dehiscentia), depressa et apud apicem declivia, ad hume- 
ros thorace paululum latiora, gradatim ad post medium ampli- 
antur; in utroque elytro coste quinque apparent, una com- 
munis suturalis, una marginalis, tresque aliae mediz intervallis 
zequis, his haud apicem attingentibus, sed costis 2 et 3 juxta 
apicem sese attingentibus ; marginatio undique ad apicem laté 
ampliatur ; quoad faciem elytra leviter et seepissime punctis 
confertis ornantur (punctis haud profundis et inordinatis), quoad 
colorem nigrescunt, humeris anguste flavis, fascidque media 
lata transversa flava ; hujus fascize margines anterior et pos- 
terior inaquales in intervallis singulis costarum subcirculares 
deflectuntur; antenne robuste sunt et nigra, articulis ad 
medium antennarum valde ampliatis ; pedes et corpus infra 
nigrescunt. 
Long. corp. lin. 6; lat. lin. 33. 
S. amplicornis differs from S$. Lycoides in being broader and 
less parallel as well as different in coloration; its much larger 
size will distinguish it from all other species of the genus before 
me. I have a single specimen from the Chevrolat Collection, re- 
ceived by M. Chevrolat from Brazil.
