262 Mr.J.S. Baty on new Genera and Species of Hispide. 
to draw up at some future period, either in the Rev. H. Clark’s 
proposed catalogue or elsewhere, a synopsis of the genera, and 
thus complete, although imperfectly, the monographie arrange- 
ment of this interesting group. 
Genus HisPo.Leptis. 
Corpus elongatum, parallelum, modice convexum, dorso sub- 
depressum. Caput porrectum, facie brevi transversa, inter antenna- 
rum insertionem crebre elevata instructum ; antennis modice robustis, 
corporis dimidio eequalibus, filiformibus, ad apicem attenuatis, arti- 
culis cylindricis, 1™° subgloboso, paullo incrassato, 24° sat brevi, vix 
incrassato, 3%° elongato, 4° illo fere dimidio breviore, caeteris ad 9°"™ 
longitudine perparum decrescentibus, 10-11™° fere sequalibus, utro- 
que 9"° paullo longiore ; mento subhastato ; oculis vix prominulis, 
elongatis, postice leviter sinuatis. Thoraw elongatulus, apice trun- 
cato, basi utrinque sinuata, lateribus fere rectis, a basi ad apicem 
angustatus, angulis anticis vix productis, acutis, dorso transversim 
convexo. Scutellum latum, pentagonum. lytra thorace vix la- 
tiora, lateribus parallelis, muticis, apice conjunctim rotundata, ser- 
rata; supra modice convexa, dorso subdeplanata, punctato-striata. 
Pedes validi, mediocres, simplices, farsorum anticorum articulo ba- 
sali sequentibus latiore ; waguiculis distantibus. 
Type, Hispoleptis (Promecotheca) diluta, Guér. Amazons, 
Cayenne. 
Genus ACANTHODES. 
Corpus elongatum aut subelongatum, dorso depressum, postice 
paullo dilatatum. Caput porrectum, inter oculos productum ; an- 
tennis rigidis, apice acutis, articulis duobus basalibus brevibus, fere 
zequalibus, vix incrassatis, 34°--11™"™" plerumque inter se coalescen- 
tibus, articulationibus seepe obsoletis, 3%°-6""™ rarius distinetis mo- 
niliformibus ; mento elongato. Thoraw basi transversus, medio de- 
pressus, ad apicem angustatus, subcylindricus, margine basali utrin- 
que profunde excavato. Scutellum transversum, apice obtusum. 
Llytra thorace latiora, subparallela, apicem versus paullo ampliata, 
apice truncata, angulo postico spina valida acuta armato; dorso 
costata, interspatiis profunde bifariam punctatis. Pedes validi; 
unguiculis contiguis. 
Type, deanthodes generosa. Amazons. 
This singular genus is remarkable for the small number of 
joints in its antenne. It ought to stand near Odontota: m some 
species no less than nine joints coalesce. 
1. Antenne with all their joints, from the third inclusive, coalescent; 
the sutural lines between them almost or entirely obsolete. 
Acanthodes generosa, ni. sp. 
A. elongata, subdepressa, rufa, oculis antennisque nigris ; elytris 
costatis, utroque sutura antice, margine exteriore macula infra
