C'arnlt'v Harbmii' ; luund uiidt'r a stone ; one imly. Preserved in tlie Canterbury 

 Museum. 



This species has lieen named in liduour of its discoverer. The description was 

 pnblislied ahinjf with that of the preredinif one ; the type I liave not seen since 1901. 



Croup ANCHOMENIDAE. 



Pristancylus, Blanchard. 



Bodi/ oblong, perceptibly convex. Head short and broad. Mandibles stout, 

 flattened above, moderately acute at the extremity. Terminal joint of the palpi 

 oval, somewhat truncate at the extremity. Mentum. trilobate, the median shorter 

 than the others and rounded at the apex. Antennae moderately thick, the 1st 

 articulation stout, the 3rd as short as the succeeding ones. Thorax cordate. Eli/fra 

 oval, rounded at the extremity. Anterior tibiae strongly notched. 



This genus, formed for the reception of two species collected at the Auckland 

 Islands, approaches Pristonychus and Sphodrus, but is distinguished from both by 

 the enlarged head and the abbreviation of the 1st articulations of the antennae. 



Pristancylus castaneus, Blanchard. 



Obloix/. slightly convex, ))rilliant dark chestnut. 



Head almost as broad as long, with 2 small unec^ual interocular foveae. An- 

 tennae nigro-fuscous, the 1st articulations shining, the others dull. Thorax cordate, 

 smooth, its sides finely margined, with a fine median groove joining an anterior 

 one, which is transverse and moderately distant from the margin. Elytra oblong, 

 a little broader than the thorax, finely striated and feebly punctured, with 1 row of 

 large marginal punctures ; the interstices perfectly smooth. Legs of the same colour 

 as the body, or slightly brighter. 



Length, 16 mm. 



Hab. — Auckland Islands. 



Pristancylus brevis, Blanchard. 



Shorter and relatively broader than the preceding, especially posteriorly. Wholly 

 rather brilliant black. 



Head as broad as long, with a very feeble depression near each eye. Antennae 

 brownish-black. Thorax short, broad, more convex than in the preceding species, 

 with a very slight rather indistinct median groove. Elt/tra oval, nearly twice the 

 width of the thorax, with somewhat fine but little-punctured striae ; on each side 

 there is a row of large punctures ; interstices perfectly smooth and flat. Legs and 

 tarsi reddish-brown. 



Length, 1-1 mm. 



Hab. — Auckland Islands. 



Obs. — Neither of these species having been found by oiu- exjjedition, translations 

 of the original descriptions have been given. The generic diagnosis does not point 

 out very clearly how these species differ in structure from Pristoni/chus. 



Calathus, Bonelli. 

 Mentum large, deeply emarginated, with a strong bifid median tooth. Ijigula 

 rounded in front. Last joint of the palpi subcylindric, truncate at tlie extremity.
