Pycnomerus Erichson. Man. N.Z. Coleopt,, p. 208. 

 4182. Pycnomerus parvulus sp. nov. 



Elongate, subparallel, slightly convex, subopaque, with some minute 

 inconspicuous setae ; nigro-piceous, antennae and legs piceo-rufous. 



Head subquadrate, its punctation moderately coarse and close, rather 

 shallow, less distinct in front. Thorax slightly longer than broad, base and 

 apex subtruncate, a little wider before the middle than elsewhere, very 

 gentlv narrowed backwards ; anterior angles not acutely prominent, the 

 posterior obtuse and indefinite ; lateral margins, in front especially, much 

 less distinct than the basal ; disc coarsely but only moderately closely 

 punctured, less deeply near the sides, the broad and rather shallow longi- 

 tudinal impression indistinctly divided along the middle. Scutellum indefi- 

 nite. Elytra oblong-oval, double the length of thorax, rather broader 

 than it is at the base, which is slightly incurved, humeral angles not 

 prominent ; the punctation of the deep striae is not sharply defined but 

 appeals elongate ; interstices finely punctate, slightly convex, scarcely 

 broader than the striae, the second bent outwardly at the extremity. 



Antennae shorter than thorax, with short slender setae ; basal joint 

 hardly visible above, the next thick and strongly transverse ; third almost 

 as broad, narrowed at its base, slightly longer than the following six, all 

 of which are strongly transverse ; tenth large, quadrate, but not at all 

 transverse, eleventh very short. 



Resembles P. frontalis (2504), in which the tenth antennal joint is trans- 

 verse, its head is rather shorter and broader with more rotundate frontal 

 impressions, and the eyes and anterior angles of the thorax are more 

 prominent. Both species belong to Section I.

Chaetosomodes gen. nov. 



Elongate, subdepressed, bearing numerous erect slender setae. Head 

 nearly as long as thorax and, including the eyes, not as broad as it is. 

 Labium short, widely e marginate. Eyes entire, prominent, somewhat 

 transversal. Antennae stout, equalling the head and thorax in length, 

 with many slender setae ; basal joint thickest, slightly longer than broad, 

 the next very short ; joints 3-8 subequal, moderately elongate, somewhat 

 narrowed towards the base, ninth and tenth slightly broader, eleventh 

 subovate. Thorax transverse, a fourth broader than long, rather wider 

 behind the middle than elsewhere, its sides moderately curved, without 

 perceptible margins ; apex truncate, the base also in the middle, but 

 marginate, and so broadly rounded towards the sides that there are no traces 

 of posterior angles. Scutellum oblong, convex, smooth. Elytra almost 

 thrice the length of thorax, finely marginate. broadly rounded at the 

 extremity, with obtuse, not at all prominent humeral angles. Pygidium 

 exposed, rounded behind. Legs moderate : femora much thicker near 

 the base than at the extremity : anterior tibiae slightly and gradually 

 expanded, each with a short calcar at the inner extremity and only about
