fourth to the eleventh inclusive, slightly compressed, of equal width. 

 Thorax twice as broad as long, sides narrowly margined, nearly straight 

 and parallel behind their middle, obliquely converging in front, anterior 

 angles thickened, slightly inflexed ; surface smooth, the impressed 

 groove on either side deeply punctured near its inner end. 



Genus Mesodonta. 

 Corpus elougatum, fere parallelum, supra pube brevi adpressa 

 vestitum. Caput modice exsertum, perpeudiculare ; antennis corpore 

 brevioribus, robustis, articulo prime curvato, a basi ad apicem incrassato, 

 secundo brevi, tertio prime longitudine sequali, subcylindrico, ad apicem 

 incrassato, cseteris compressis, modice dilatatis, quatuor ultimis 

 latitudine paullo decrescentibus ; ociilis prominulis, integris ; palpis 

 maxillaribus ovatis, apice acuminatis. Thorax transversus, lateribus 

 obtuse angulatis, postice parallelis, autice convergentibus ; disco 

 irregulariter excavate. Elytra thorace latiora, parallela, convexa, infra 

 basin non transversim depressa, confuse punctata. Pedes robusti, sub- 

 elongati, simplices ; coxis anticis erectis, contiguis ; femoribus posticis 

 non incrassatis ; tihiis intermediis apice spina acuta armatis ; unguieulis 

 bifidis. Prosternum fere obsoletum. 



Type, Mesodonta (Glitena, olim) limbata, Baly. 

 On examination, I have been compelled to separate this species 

 from CUtena, and to place it in a separate genus, owing to the singular 

 character presented by the intermediate tibise, the apices of which are 

 armed by an acute spine, the anterior and hinder pairs being unarmed ; 

 this (as far as I have at present examined) is peculiar to the genus 

 of GallerucidcB before us. In all other known cases where a single pair 

 of tibiae are furnished with spines, they are attached to the hinder pair 

 alone ; in Glitena (of which CUtena melancJiolica must be considered 

 the type) all the tibia? are unarmed, the elytra are more or less dilated, 

 and have a transverse depression below the basilar space. In my 

 diagnosis of CUtena, I find that I have erroneously written " Caput 

 thorace insertum ; " it ought to read " exsertum."
