and of uncharacterized species of Ilalticince. 307 



joints stained with piceous ; labrum and jaws sometimes 

 piceous. Thorax nearly twice as broad as long; sides 

 parallel, very slightly rounded, anterior angles thickened, 

 obliquely truncate, hinder angles acute ; upper surface 

 granulose, finely but distinctly punctured. Scutellum 

 semirotundate. Elytra broader than the thorax, oblong- 

 ovate, attenuated towards the apex, convex, regularly punc- 

 tate-striate, intersj^aces finely granulose, faintly wrinkled, 

 each impressed with a single row of very fine j^imctures. 



The punctuation both of the thorax and elytra varies 

 somewhat in degree in different individuals ; the species 

 is apparently common. 



Chatocnema hraziliensis. 



Anguste ovata, convexa, nitida, subtus nigra, pedibus 

 fulvo-piceis, femoribus posticis piceo-cupreis ; supra cu- 

 prea, seneo tincta, antennis fulvis, extrorsum rufo-j)iceis ; 

 thorace granuloso, evidenter, minus remote punctato ; 

 elytris sat fortiter punctato-striatis, interspatiis nitidis, 

 convexiuscidis, externis convexis. 



Long. I lin. Hah. — Brazil. 



Head not longer than broad, subtrigonate ; vertex and 

 front gi-anulose, impressed on either side with four or 

 five round punctures ; oblique grooves separating the in- 

 terocular spaces from the front distinct, deeply impressed ; 

 carina oblong, Avell defined on the sides, its surface plane, 

 not raised above the disk of the clypeus ; its apex sepa- 

 rated fi'om the face by a transverse groove; antennae more 

 than half the length of the body, fulvous, slightly stained 

 with rufo-piceous towards the apex ; second joint mode- 

 rately thickened, nearly as long as the first, equal in 

 length to the third. Thorax twice as broad as long; sides 

 rounded and converging fi-om base to apex, nearly parallel 

 at the extreme base ; anterior angles thickened, oblique ; 

 upper surface coarsely granulose, impressed with distinct, 

 aciculate, subremote punctures. Elytra broader than the 

 thorax, ovate, attenuated at the apex ; convex, regularly 

 punctate-striate ; interspaces nitidous, irregularly wrinkled 

 at the extreme base near the suture, slightly convex, more 

 strongly so near the outer margin ; on each intersjjace 

 (when viewed under a strong lens) are seen a few minute 

 punctures.
