neio genera and species of Cri/ptuceplialldcB. 221 



Cryptocephalus histrionicus. 



Anguste oblongus, subcylindricus, subtus cum capite 

 sordide fiilvus, pectore pallide piceo, vertice, antennis 

 extrorsum oculisque nigris; supra pallide jiiceus, thoracis 

 margiuibus antico et laterali maculisque duabus baseos, 

 sordide fulvis ; eljtris fortiter punctato-striatis ; utrisque 

 fascia transversa vix pone medium, utrinque abbreviata, 

 postice leviter emarginata, macula ante apicem lineaque 

 subapicali prope suturam posita, albis, ornatis ; his signa- 

 turis la^vibus, impunctatis. 



Long. 1 lin. 



Ilah. — Brazil, New Friburg. 



Eyes, large, sej^arated at their apices by a narrow line ; 

 antennae more than three-fourths the length of the body, 

 lour lower joints fulvous, the fifth piceous, the rest black. 

 Thorax nearly twice as broad at the base as long ; sides 

 rounded and converging from base to apex, rather more 

 obliquely converging before the middle, hinder angles pro- 

 duced posteriorly, acute ; basal margin scarcely sinuate on 

 either side, medial lobe not produced, slightly concave ; 

 upper surface convex, slightly impressed transversely on 

 either side just behind the middle, coarsely but not very 

 closely punctured. Scutellum wedge-shaped, its apex ob- 

 tuse. Elytra oblong, sides slightly lobed; each elytron 

 transversely excavated just below the basal margin, im- 

 pressed with eleven rows of coarse deep punctui-es, rather 

 smaller and less deeply impressed towards the apex ; on the 

 white markings these punctui-es are entirely obsolete ; inter- 

 spaces plane, convex and subcostate near the outer margin. 



Crypi tocephaliLS amazonus. 



Elongatus, subcylindricus, niger, nitidus, capite (an- 

 tennis extrorsum oculisque exceptis), thoraceque rufb- 

 fulvis, pedibus flavo-fulvis ; thorace subconico, utrinque 

 oblique impressio, subremote pvmctato; elytris basi ti-ans- 

 versim excavatis, sat fortiter punctato-striatis ; inters2)atiis 

 planis, ad apicem convexiusculis, ad marginem exte- 

 riorem subcostatis. 



Long. 1^ lin. 



//o6.— Para. 



Head rather strongly punctiu'cd ; eyes nearly con- 

 tiguous, being only se})arated by a fine line ; antenn;ii 

 rather more than half the length of the body, slender, the 

 four lower joints pale flavous, the rest black. Thorax 

 rather broader at the base than long, subconic; sides
