Meso7nphalia laUssima. < 



Rotundata, longitudine distincte latior, modice con- 

 vexa, obscure nigro-senea, subopaca^ subtus niagis 

 nitida, antennis nigris ; thorace longitudine fere duplo 

 latiori^ apice distincte emarginato, lateribus pone apicem 

 fere ad medium oblique rotundato-ampliatis, deinde 

 rotundatis, pone medium ad basin rectis, parallelis ; dorso 

 medio convexo, longitudinaliter canaliculate, utrinque 

 concave, lateribus late reflexis ; disco dense argenteo- 

 sericeo, lineis duabus, una longitudinali, altera transversa, 

 disci medio positis, crucis figuram formantibus glabris ; 

 elytris longitudine distincte latioribus, basi truncatis, 

 fere transversis, humeris late rotundatis, non prominulis, 

 lateribus pone humeros rotundatis, pone medium ad 

 apicem angustato-rotundatis, apice late rotundatis ; disco 

 modice convexis, pone basin citius elevatis, pube ad- 

 pressa cinerea sparsissime vestitis ; subcrebre sed tenuiter 

 punctatis, interstitiis Isevibus, prope suturam obsolete 

 elevato-reticulatis ; margine laterali latissimo, fere piano, 

 obsolete transversim strigoso, plaga magna a basi ad 

 longe ultra medium producta, postice attenuata, ante 

 apicem desinente, rufo-testacea, ornato. 



Long. 8^, lat. 9 lin. 



Hah. — Ecuador. 



Very closely allied to M. lateviitata, Boh., and pos- 

 sibly only a variety of that species ; differing principally 

 in its transverse form, and in the absence of the reticu- 

 lations, which in the former insect are spread over the disc 

 of the elytra; the nigro-£eneous edge of the lateral mar- 

 gin of the elytron is also broader, and the rufo-testaceous 

 vitta terminates much sooner. 



Mesomphalia consociata. 



Late rotundato-ovata, postice attenuata, leviter con- 

 vexa, nigro-genea, subnitida, pube subdepressa cinerea 

 sparse vestita, antennis nigris ; thorace longitudine plus 

 duplo latiori, lateribus pone apicem ad longe ultra medium 

 oblique ampliatis, hinc ad basin rectis ; dorso opaco, 

 pube sericea depressa sparsissime adsperso, medio con- 

 vexo, utrinque concave et ibi unifoveolato, lateribus late 

 reflexis ; elytris thorace multo latioribus, a basi fere ad 

 medium rotundato-ampliatis, hinc ad apicem rotundato-
