prothorax latitudine postica quarto brevior, lateribus vix arcuatus 

 antice leviter attenuatus, basi apice fere tertio latior angulis posticis 

 obtuse rotundatis, basi distincte marginatus, supra corivexiusculus, 

 in medio anguste canaliculatus, impunctatus ; elytra prothorace 

 baud latiora, duplo longiora, oblonga, postice conjunctim rotundata, 

 apice vix singulatim sinuata, supra-convexa, anguste punctato 

 striata, interstitiis levibus, convexis ; corpus subtus fere glabrum,

Long. 6 mm. ; lat. 2^ mm. 



This species is most probably allied to M. amoenula, Boh., but it 

 differs in several points, such as the convex intervals of the elytra, 

 the sutural black band, and also the marginal ones, which are of the 

 same length and surround both sides of the yellowish postical 

 macules, each of which extend from the second to the sixth interval.

Intermediate in shape between T. iMllipes, Boh., and T. tabula, 

 Per. The elytra are less broadly rounded at the shoulders than in 

 the latter, and are therefore less ovate ; they are more broadly 

 rounded there than in T. iKtlUpes.

 Nigro piceus, nitidissimus ; antennae infuscatge articulis basalibus 

 duobus rufescentibus ; pedes rufo brunnei ; caput impunctatum,
