360 COLEOPTERA. 
the suture, with slightly convex interstices there, especially behind, the 3rd 
usually bipunctate ; the outer striae more slender, with flatter interstices, 
lateral margins reflexed, with narrow channels before the middle, and just 
above these there is an irregular series of large punctiform impressions on 
each ; scutellar striae well marked. 
The strongly sinuate sides, and unusually prominent posterior angles of 
the thorax, rather convex hind-body, and the individually broadly rounded 
apices render this species abundantly distinct. 
Q. Length, 9-10 mm. ; breadth, 3}-4 mm. 
Routeburn and Hollyford, north-west of Lake Wakatipu. Two females 
obtained by Mr. T. Hall in February, 1914. 
Obs—At Scarcliff, Mistake Basin, and Mount Algidus, over fifty miles 
west of Methven, in Canterbury, Mr. Hall found three specimens, one of 
them a male, measuring 10mm. by 44mm. These are not satisfactorily 
differentiated from the larger type of D. thoracica (2662), and are therefore 
labelled “‘ var. 2662.’ All the species of the genus are very rare. 
3799. Dichrochile rugicollis sp. nov. 
Subdepressed, oblong, nitid ; black, tarsi rufo-piceous. 
Head and large eyes slightly broader than front of thorax, nearly smooth 
on the middle, with numerous fine yet distinct irregular striae. Thorax 
transverse, a third broader than long, widest just before the middle, a little 
rounded there, gradually and slightly narrowed behind, its base subtruncate 
but slightly curved and oblique at the sides so that its angles are obtuse, 
apex widely but not deeply emarginate ; disc with fine transverse striae, 
the base densely finely irregularly longitudinally striate, the apex more 
deeply but less closely ; basal fossae large but not sharply limited so that 
the sides appear unevenly depressed. Elytra oblong, more than thrice the 
length of thorax, a fourth broader, with curvedly narrowed shoulders, and 
oblique, distinctly sinuate apices; each has 6 moderately deep, obsoletely 
punctate striae, and slightly convex interstices, the 3rd are bipunctate. 
Doubtless closely allied to D. aterrima (37), but as Bates in his descrip- 
tion does not allude to the sculpture of the head and thorax, which he 
would not be likely to disregard, and as the elytral apices are evidently 
sinuate, I think this must be a valid species. 
9. Length, 10 mm.; breadth, nearly 4mm. 
Oakden, near Mount Algidus. One found by Mr. T. Hall or Mr. 
Roderick Urquhart when collecting together on the latter’s property on 
the 9th October, 1913. 
3800. Dichrochile flavipes sp. nov. 
Oblong-oval, subdepressed, nitid, head and thorax rather less so; these 
are infuscate-black, elytra fusco-castaneous, sides of the latter and of 
the thorax flavo-fuscous; legs, antennae, palpi, and labrum more or less 
testaceous, mandibles rufescent. 
Head longer but rather narrower than thorax, with a single setigerous 
puncture near the inner and back part of each eye. Thorax widely emar- 
ginate in front, the base more deeply in the middle, the length between 
these only half of the greatest width, at or just before the middle, mode- 
rately curvedly narrowed anteriorly, gradually narrowed behind ; posterior 
angles obtuse but not broadly rounded, the anterior somewhat prominent ; 
disc fecbly irregularly striate, sometimes longitudinally near the middle of
