Heterodactylus, Guerin. 

 Labrum transverse, entire ; mandibles not very promi- 

 nent, bent, without teeth on the inside, much widened at 

 the base and ha\Hng on the outer side a wide fossa which 

 receives the first joint of antennae; palpi elongated, fili-

 notch wide, in the middle with a rounded projection ; 

 tongue wide, very prominent between the labial palpi ; 

 antennae filiform ; anterior tibiae strongly notched beneath 

 only, with the four first joints of the tarsi strongly dilated 

 in the males, rounded on the sides, much contracted be- 

 hind and very distinctly cordate, the fourth having the 

 inner lobe much more elongated than the outer ; interme- 

 diate tarsi with triangular joints not so much dilated as 

 the anterior, but wider than those of hind legs ; these four 

 tarsi have their fourth joint much prolonged on the outer 

 side ; thorax cordate ; body apterous.

Shining black ; head smooth, with two wide fossae 

 in front ; mandibles with one tooth, margins widened,

 transverse impression in front and two rather deep fossae 

 behind, near the hind angles ; scutellum rounded, slightly 

 rugose ; elytra oval, of the width of thorax at base, without 



humeral projections, feebly margined, widest in the middle, 

 smooth, and with nine stria3, distinct on the disk but nearly 

 obliterated on the sides ; these striae do not all reach the
