it may not be a variety of P. sophor. The same remark applies to P. rufescens, 
Broun. The other species described by Broun, P. simplex, ellipticus, and basalis, 
are, I am pretty sure, unknown to me, and distinct from any I have described. 
Pycnomerus longulus, n. sp.—Elongatus, angustulus, nitidus, piceus, antennis 
pedibusque rufis ; interdum rufescens; antennarum clava evidenter divisa; prothorace 
angustulo, angulis anterioribus nullo modo prominulis, disco vage impresso; 
elytris striatis, striis fortiter punctatis, interstitiis planis. Long. 31 m.m. (Plate 
x, ns. 21.) 
Antennz moderately stout ; thorax narrowed behind, slightly longer than broad, 
closely and coarsely punctate, the dise vaguely depressed, the depression duplicate 
behind, single in front. Shoulders of elytra free, not at all prominent. 
This is closely allied to P. minor, though very distinct by reason of the 
evidently divided club of the antenna. It is also more elongate, and the thoracic 
impression is a little less obsolete. Ido not think the rufescent form is distinct 
from the dark one.

Pycnomerus helmsi, n. sp. 
Parum elongatus, nitidus, piceus; capite elongato, 
oculis minoribus ; prothorace oblongo, disco impressione oblonga magna et profunda 
anguste divisa; elytris suleatis, sulcis leviter flexuosis, haud punctatis, post 
scutellum transversim depressis. Long. 35 m.m. 
Antenne stout, with club large and only very indistinctly divided, the terminal 
or pubescent portion small; head densely punctate; thorax scarcely perceptibly 
narrowed behind the sides, a little contracted near the front angles, which are not 
prominent, the surface shining but rather closely and coarsely punctate, the disc 
occupied by a large and deep oblong depression, which is only divided by a slight 
carina along the middle; elytra with very deep strize, which are not sculptured, 
though their edges are a little flexuose, the base is emarginate but the humeral 
angles are not acute, and immediately behind the scutellum the surface is 
depressed ; metasternum rather short. 
This interesting species is an intermediate form between the normal and 
ordinary New Zealand Pycnomeri as represented by P. sophore, and the blind 
forms of which P. sulcatissimus may be taken as the type. The only examples I 
have seen are the three sent by Mr. Helms, after whom I have consequently 
named it. 
Greymouth. Helms, No. 291. 
Pycnomerus sulcatissimus, n. sp.—Nigerrimus, nitidus, oculis minutis, antennis 
pedibusque rufis; prothorace oblongo, fortius punctato, disco profunde impresso, 
impressione anguste divisa; elytris profunde sulcatis, sulcis leviter flexuosis. 
Long. 34 m.m. (Plate xu, fig. 22.)
