instructis. 
Antenne 11-articulate, extrorsim crassiores, rostro paull6 ante medium insidentes, 
articulo primo longiusculo subarcuato extrorsim crassiore, secundo brevi obconico, 
tertio quartoque subzqualibus, quinto prioribus duobus breviore, insequentibus 
quinque magnitudine crescentibus obconicis extrorsim crassioribus, ultimo pre- 
cedenti paulld longiore ad apicem conico. Labrum vix distinctum. Labium anticé

1"Ioos, equalis; dxavOa, spina. The two spines on each of the anterior femora are of equal size. 
* To another nearly allied and novel genus, lately received from the same country, I have given the name of 
Pachyura: it may be thus briefly characterized :— 
Isacanthe affinis; antennis extrorstm crassioribus ; rostro deflexo ; thorace anticé angustiore ; elytris posticé 
valde dilatatis ; pedibus inermibus. 
The species on which this genus is founded I have named Pach. Australis.
