It is similar in size and colour to A. pauxillus, Blackb., as 

 well as in its general appearance, but there is no trace of 

 thoracic depression or tubercle, while the very feeble 

 ])uncturation of the pronotum, elytra, and pygidium also 

 distinguish it immediately. Tlie clypeus.on the other hand, 

 is more strongly puncturt-d ami of different shape, being 

 rather long, narrow, and strongly rounded in front. The 

 pronotum is less convex, less deeply sinuated at the base, 

 with the front angles less sliarp and tlie liiiid angles dis- 

 tinctly indicated. 



I have received specimens from ^lessrs. Staudinger and 

 Bang-Haas. 



Ligyrus amozoni'cus, sp. n. 



Nigro-piceus, vel supra toto niger, nitidus, clongato-ovalis, capita 

 transverse rugoso, clypeo antice acutissime bidentato, postice 

 bituberculato ; pronoto fortiter sat crebre punctato, antice ad 

 marginem minute tuberculato et impresso ; scutello subtiliter 

 punctulato ; elytris undique fortiter et crebre punctatis, punc- 

 torum lineis nonnuUisgeminatis ; pygidio baud fortiter punctato, 

 angulis anticis rugulosis ; utriusqiie sexus pedibus omnibus 

 siraplicibus.

Lijyrus ebenus, inaa;ivius,iin(\. omazonicus have been found 

 all togetlier in various localities in the Amazons region. 

 They are closely related and exceedingly similar in shape 

 and sculpture. In the last two the front tarsus of the male 

 is not thickened, the clypeus is much more sharply bidentate 

 and the pronotum more strongly punctured than in L.ehenu'i, 

 Deg. From L. maaimiis, Arrow, the new species is easily 

 distinguished by its smaller size and the very feeble de- 

 pression at tlie I'ront edge of the |)ronotiim. 



Ligyrus latus, sp. n. 



Nigro-piceus, vel supra toto niger, nitidus, robustus, late ova] is, 

 capite transverse rugoso, clypeo antice acute bidentato, postice 

 bituberculato; pronoto fortiter sat crebre punctato, margine 

 antico medio minute tuberculato et longitudinaliter impresso, 

 lateribus rcgulariter arcuatis, angulis postieis toto obsoletis, basi 

 medio fere exciso ; scutello perpaulo punctulato ; elytris undique 

 fortiter et crebre punctatis, punctorura lineis nonnullis geminatis ; 

 pygidii basi subtiliter rugoso, apice parce punctulato ; utriusque 

 sexus pedibus omnibus simplicibus. 



Long. 27-31 mm.; lat. max. 15-17 mm.
