Group Anc'homenid^. 

 Anchomenus chathamensis, sp. nov. 



Suhoblong, slightly convex, nitid, piceous ; the legs, antennae, and palpi 

 rufo-piceous ; lateral margins of thorax and elytra similarly rufescent. 



Head oviform and, including the large eyes, rather broader than front 

 of thorax ; irregularly rugose behind the inter-antennal groove, smooth 

 on the back part. Labrum large, entire. Antennae with the basal 3 joints 

 shining and glabrous, 2nd joint half the length of the 3rd. Thorax one- 

 fourth broader than long, its sides with well-developed margins, moderately 

 rounded, very gradually narrowed behind the middle, posterior angles 

 nearly rectangular but obtuse, the base feebly rounded towards the sides, 

 apex incurved ; disc moderately convex, with feebly impressed stria? across 

 it, dorsal furrow indistinct near the base and apex, near the front there is 

 an indistinct transverse impression, basal fossae large. Scutellum smooth. 

 Elytra oblong, slightly and gradually widened backwards, slightly sinuate 

 but evidently obliquely narrowed towards the apices ; shoulders a little 

 curvedly narrowed, yet rather wider than the base of thorax ; the suture 

 is somewhat elevated posteriorly, the 4 discoidal stria? on each elytron are 

 well marked but impunctate, the outer ones are finer, 3rd interstices tri- 

 puncta te. 



Tarsi setose, the anterior spongy underneath, their basal 2 joints 

 moderately dilated and oblong, the 3rd also dilated but shorter and more 

 narrowed near the base, 4th small and cordiform, basal joint of the posterior 

 grooved along the outside. Palpi rather short, terminal articulation sub- 

 cylindric. 



Underside shining piceous, last ventral segment very broadly rounded, 

 almost truncate, with a single setigerous puncture near each side at the 

 apex.
