Metaxyonycha tetrasticta, sp. ined. 



M. elongata, cyliridrica, testacea; oculis, antennarum articulis 3-12, 



tarsis, maculis in utroque elytro binis rotundis nigris. 

 Long. lin. 4\, lat. hum. 1^ lin. 



More elongate and cylindrical than the preceding, the elytra 

 less convex, parallel for four-fifths of their length, more broadly 

 rounded, and less suddenly deflexed posteriorly. Punctuation 

 similar, but somewhat coarser; the interstices less conspicuous, 

 except towards the costated apex. Eyes large and prominent. 

 Uniformly reddish testaceous, the elytra paler and yellowish. 

 Each elytron with two circular black spots, the anterior and 

 larger situated near the base, equidistant from the suture and 

 the outer margin ; the other behind the middle, at the distance 

 of two-thirds from the exterior margin, and one-third from the 

 suture. 



Hob. Brazil. Common in collections. 



Metaxyonycha Tejucana, sp. ined. 



M. maxima, castanea; oculis, mandibulis apice, antennarum articulis 

 4-12, tibiis extremis, tarsis nigris: oculis intus emarginatis ; 

 thorace mutico ; elytris 8-costatis, inter costas seriatim punctatis; 

 tibiis intermediis fortiter emarginatis. 



Long. lin. 7, lat. hum. 2f lin. 



Cognate with M. tricolor : front marked as in that species, 

 with the addition of an impressed line upon the vertex, reaching 

 the interocular fovea. Head and thorax with scattered punc- 

 tures ; the latter subquadrate, as broad in front as behind, mo- 

 derately rounded at the sides, where it is broadly margined ; 

 only slightly convex, truncate anteriorly and at the base. Elytra 

 broader than the thorax, more than four times its length, with 

 eight smooth costse visible from the base to the apex. The 

 humeral callus shining and prominent. The fifth, sixth, and 

 eighth costse reach the callus, the seventh is abbreviated ante- 

 riorly. All the costse are more distinct towards the sides and 

 apex. Interstices punctate-striate, the punctures in single rows 

 near the suture, afterwards doubled, tripled, and finally confused 

 in the lateral spaces. Entirely castaneous, beneath paler ; tibise 

 darker, blackish at the apex. 



It strongly resembles Colaspis acuminipennis, Blanch., figured 

 in D^Orbigny^s ' Voyage,^ pi. 24. fig. 10.
