Caput pauUo exsertum, antice brevissimum, latum, 

 fronte convexa, subverticali, hand impressa. Oculi 

 laterales, supra distantes, valde emarginati, fere 

 divisi. Antennce breviusculee, extus gradatim cras-

 late ovato, depresso. Prothorax subquadratus, basi 

 constrictus. Elytra subparallela, abdomen tegentia, 

 marginibus externis serratis. Pedes antici et inter- 

 medii breves, postici multo longiores; fennora cla- 

 vata; tibice posticae arcuatas, extus denticulatae, 

 apice calcaratae ; tarsi postici articulo basali elongato. 

 Prosternutn depressum, sat latum. Mesosternum 

 latum, vix declive, postice truncatum. Processus 

 intercoxalis late rotundatus. Abdomen ut in Merio- 

 noeda. 



This genus differs from Merionceda in its head and 

 elytra, the latter serrate or denticulate at their outer 

 margins, in the presternum and mesosternum being 

 nearly on the same plane, the former broad and the latter 

 truncate behind, in the rounded intercoxal process, and 

 the short broad porrect head without any frontal im- 

 pression, and the eyes nearly entirely divided. On the 

 other hand, it has the same habit and coloration, as well 

 as the same remarkable structure of the abdomen, and 

 denticulate posterior tibiae.
