390 Suarp—On New Zealand Coleoptera. 
This is distinguished amongst the allies by the very deep oblong impression on 
the middle of the thorax, which is divided only by a narrow carina, extending all 
along the depression, but less distinct in its anterior part. The eyes are very 
minute, but still are very easily detected. The eleventh joint of the antenna 
appears merely as a pubescent apex to the tenth. The thorax has the anterior part 
of the sides slightly narrowed, the front angles slightly prominent, and the hind 
angles also distinct. The striation of the elytra is very strong, even the sutural 
stria being broad and deep, and the strize not irregular. The metasternum is very 
short. 
I am not sure but that there may still be two species mixed under this name ; 
some of the individuals are only 2} m.m. long, and are piceous in colour, the 
thoracic depression less, and more distinctly separated into two by a broader space ; 
I have not, however, seen enough examples of the two forms to enable me to come 
to a decision, and prefer treating these smaller specimens merely as a variety. 
Greymouth. I have retained for this species the trivial name under which it has been distributed 
by Herr Reitter. 
Pycnomerus latitans, n. sp.—Nigerrimus, nitidus, oculis minutissimis, antennis 
pedibusque rufis; prothorace oblongo, fortius punctato, disco leviter biimpresso ; 
elytris profunde sulcatis, sulcis flexuosis. Long. 34 m.m. 
This is very similar to P. sulcatissimus, but is distinguished by some good 
characters; the lateral margin of the thorax just before the front border becomes 
thimer, and thus the thorax has an appearance of being suddenly though 
slightly narrowed in front, and there is no prominence of the front angle; the disc 
has only two slight impressions, separated by a rather broad space; there is no 
transverse depression on the wing cases behind the scutellum, whereas in P. 
sulcatissimus the second stria on each elytron is connected by a transverse 
depression extending behind the scutellum, so that its hind margin is raised; and 
in P. latitans the sculpture of the grooves or striz is not so effaced as it is in P. 
sulcatissimus, and the eyes are even more minute. 
Greymouth. Helms, No. 205. 
BoTHRIDERES. 
Bothrideres cognatus, n. sp.—Niger, antennis elytris pedibusque ferrugineis, 
prothorace subquadrato, fortiter punctato, dorso foveolato, angulis posterioribus 
argute rectis; elytris apicem versus subcostatis. Long. 43 m.m. 
Very closely allied to B. meestus, though readily distinguished by the colour of 
the legs and elytra; the sculpture is almost identical in the two species, except 
that it is a little more obsolete on the elytra in B. cognatus; the latter is, however,
