[Read 6th Nov. 1865, 5th Feb, 1866.] 
Genus SypuaAxta. 
Corpus robustum, ovatum, postice paullo ampliatum, valde con- 
vexum, sericeo-pubescens. Caput modice exsertum, facie 
perpendiculari; antennis corporis dimidio zqualibus, robus- 
tis, vix fusiformibus, articulis cylindricis, primo a basi ad 
apicem incrassato, curvato, secundo brevi, tertio quam primo 
longiori, quarto quam tertio paullo breviori, czteris ad 
apicem brevioribus et inter se fere equalibus. Thorax trans- 
versus, transversim excavatus. LElytra ovalia, confuse punc- 
tata. Pedes robusti; covis anticis erectis, contiguis ; femori- 
bus posticis non incrassatis ; tibiis omnibus apice muticis; 
tarsorum posticorum articulo basali duobus sequentibus con- 
junctis vix breviori; wunguiculis muticis, basi incrassatis. 
Prosternum fere obsoletum. 
Type, Syphaxia (Monocesta) spectanda, Clark. 
Syphaxia may be known from Monocesta by its unarmed ungui- 
culi and its much shorter antennze ; and the body is shorter and 
more convex, as well as more regularly ovate, than in the majority 
of the species of Monocesta. 
Sp. 1. Syphaxia spectanda, Clark. 
Monocesta spectanda, Clark, Ann. & Mag. Nat. Hist. 1865, p. 315. 
In the Rev. H. Clark’s specimens, the antenna are wanting ; 
in the specimen before me (which also came from Cayenne) the 
antennze are nigro-fuscous, with the exception of the bases of the 
four lower joints, which are flavous. 
Genus Cuorina. 
Corpus elongatum, parallelum, convexum, sericeo-pubescens. 
Caput exsertum, facie perpendiculari; an/ennis modice ro- 
bustis, corporis longitudine brevioribus, filiformibus, apicem 
versus vix incrassatis, articulis cylindricis, primo a basi ad 
apicem incrassato, curvato, secundo brevi, tertio elongato, 
quatuor sequentibus longitudine perparum decrescentibus,
