with a bluish shade ; regularly and rather strongly punc-

 bus fulvis ; supra nigro-cgerulea, metallica, antennis fulvis, 

 extrorsum nigris ; thorace remote punctato ; elytris sat 

 fortiter striatim punctatis, punctis in striis confuse dis-

Long. 1 — 1^ lin. Hab. — Brazil, New Friburg. 



Head trigonate ; vertex nitidous, sparingly impressed 

 with a few fine punctures ; front impressed along its loAver 

 edge on either side with four or five stronger punctures, 

 its medial portion with a faint longitudinal depression ; 

 encarp^ very distinct, narrow, elongate, obliquely trans- 

 verse, separated by a deep fovea ; carina obsolete ; clypeus 

 subtrigonate, its upper portion thickened ; labrum and 

 jaws piceous ; antennte half the length of the body, six 

 lower joints fulvous, the apices of the fifth and sixth 

 stained with piceous, the five outer ones black ; the second 

 joint short, ovate, the third nearly twice as long as the 

 second. Thorax nearly three times as broad as long ; 

 sides rather broadly margined, regularly rounded, anterior 

 angles obtuse, the hinder ones acute ; upper surface re- 

 motely impressed with fine but deep punctures. Elytra 

 broader than the thorax, narrowly oblong, convex, slightly 

 flattened along the suture, rather strongly punctate-striate, 

 the punctures on each stria very irregularly arranged, 

 those near the suture very confused ; interspaces smooth 

 and shining, sparingly impressed with minute punctures. 



Aphtliona fulvipes. 



Anguste ovata, convexa, nigra, nitida, antennis pedi- 

 busque fulvis, femoribus posticis piceis ; thorace sat remote, 

 tenuiter punctato ; elytris convexis, utrisque infra basin 

 leviter transversim depressis, fortiter punctato-striatis, 

 interspatiis planis, externis obsolete convexiusculis.
