Criodion quadrimaculatum, sp. n. 
Fuscum; capite prothoraceque griseo-pubescentibus ; prothoracis 
dorso lateribusque rugoso-punctatis, illo medio carina brevi paullo 
elevata ; elytris testaceo-fulvis, subopacis, sparsim setosis, utrisque 
marginibus externis maculisque duabus (una sub humerum oblonga 
parum nitida marginem attingente, altera discoidali rotundata 
paullo pone medium) fuscis ; apicibus truncatis, utrisque bispi- 
nosis ; corpore subtus griseo-pubescente ; antennis quam corpore 
sesqui-longioribus. 
do. Long. 38, lat. 10 mm. 
Hab. Brazil. 
Dark brown, with a greyish pubescence. Prothorax 
strongly and somewhat rugosely punctured ; the sides nearly 
arallel ; the disk with a short feeble carina in the middle. 
ilptrat fulvous, opaque, sparsely punctulate, with very short 
yellowish sete springing trom the punctures, with the extreme 
lateral and apical margins and two spots on each dark brown ; 
of these spots one (oblong) is placed under the shoulder in 
contiguity with the outer margin, the other (rounded) is situ- 
ated on the disk a little behind the middle; apices of the 
elytra truncate, each with two moderate-sized spines. _ Inter- 
mediate femora unidentate ; posterior bidentate at their distal 
extremity. ‘libize spined at their outer termination. Inter- 
mediate cotyloid cavities open externally. 
This species seems nearly enough related to the preceding 
one, and for similar reasons must be placed in Crtodion.

Criodion Sommeri (Dej. Cat.). 
Nigro-fuscum ; capite prothoraceque griseo-fulvo pubescentibus ; 
prothoracis dorso lateribusque rugoso-punctatis, medio disco tuber- 
culo glabro plano antice in carinam prolongato; elytris fulvo- 
testaceis, pilis fulvis erectis dispersis, maculis septem fuscis—una 
elongata utrinque sub humerum, una communi subcordata pone 
scutellum, duabus utrinque pone medium obliquiter dispositis ; 
marginibus externis suturaque angustim infuscatis ; apicibus trun- 
catis, ad suturam breviter spinosis ; corpore subtus fulvo-villosis ; 
pedibus fuscis, fulvo sparsim setosis, femoribus utrisque macula 
dorsali rufo-testacea; antennis sparsim pilosis, quam corpore 
sesquilongioribus.
