Genus APORESTHUS, nov. gen. 
Corpus sub-depressum, glabrum. Caput ovatum. Antenne filiformes, 
articulis 4—11 dense pubescentibus. Labrum antice truncatum, angulis rectis. 
Mandibule anguste, elongate, apice leviter falciformes. Mawville anguste, 
intus sparsim spinulose, lobo exteriori equaliter bi-articulato. —Palpi omnes 
elongati, graciles, nudi, articulo ultimo sublineari, precedenti sub-equalt. 
Liguia elongata, angusta, antice sinuato-truncata, bisetosa, angulis truncatis, 
liberis ; paraglossis angustis brevior.  Mentum angustum, sub-equaliter, 
acute trilobum. Thorax parvus, cordatus. Elytra ovata, sub-depressa, apice 
late truncata ; stria marginali per apicem continuata. Pedes graciles, viz 
setosi ; tarsi lineares, supra nudi, unguiculis simplicibus ; maris articulis 3 
anticis vie dilatatis, subtus bi-seriatim squamulosis. Epimera mesothoracica 
angusta, parallela, covas haud attingentia. 
The genus is distinct from the Coptoderine, Lebiine, and allied 
groups by the paraglosse being non-adherent to the upper angles of the 
ligula. In the form of head and trophi it has much resemblance to Diplo- 
harpus (Anchomening), but the form of the mentum and other parts 
of the mouth, added to the truncated elytra, seem to point to the Oda- 
canthine as its approximate position.
