494 Mr. J. SFBaly’s Descriptions of 
purpureo tinctis, limbo laterali, apice fasciaque mediali 
fulvis. Long. 53 lin. 
Hab. Brazil; a single specimen from Deyrolle’s 
collection. 
Face excavated between the eyes; vertex and front 
distinctly punctured ; clypeus shining impunctate ; eyes 
subreniform, concave-emarginate, shining black; an- 
tenne nearly equal to the body in length, slender, 
filiform, the four lower joints fulvous, the rest black. 
Thorax nearly twice.as broad as long; sides diverging 
from the base to just beyond the middle, where they are 
produced into an ill-defined tooth, from thence they 
obliquely converge towards the apex; disk strongly and 
irregularly punctured, impressed on either side with a 
deep transverse excavation. Elytra much broader than 
the thorax, parallel, conjointly angulate at the apex, 
convex, transversely excavated below the basilar space, 
the latter thickened; each elytron with nine strongly- 
elevated longitudinal cost, the first next the suture 
short ; interspaces irregularly gemellato-punctate. 
This species agrees in coloration with M. fasciata, 
Lef.; it differs from that insect (judging from the 
author’s description) in the angular sides of the thorax, 
and in its disk being transversely excavated on either 
side, a character not mentioned by M. Lefévre. 
Metaxyonycha pretiosa. 
Subelongata, convexa, fulva, nitida, antennis, basi 
exceptis, tibiis tarsisque, nigris; thorace transverso, 
disco rude punctato, utrinque profunde transversim 
excavato, lateribus subangulatis, medio breviter tyri- 
dentatis; elytris anguste oblongis, apice conjunctim 
angulato-rotundatis ; convexis, infra basin vix excavatis, 
callo humerali prominenti; rugoso-punctatis, longi- 
tudinaliter costatis, costis fere omnino deletis, ad apicem 
confusis; viridi-cyaneis, margine laterali, apice fasciaque 
prope medium, fulvis. Long. 6 lin. 
Hab. Ecuador; collected by Mr. Buckley.
