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 puiictifoim impressions on 

 each ; scutellar striae well marked. 



The strongly sinuate sides, and uiuisually prominent |)osterior angles of 

 the thorax, ratlier convex hind-body, and the individually broadly rounded 

 apices render this species abundantly distinct. 



$. Length. 9-10 mm. ; breadtli, 3^4 mm. 



Routeburn and Hollyford, north-west of Lake Wakati))u. Two females 

 obtained by Mr. T. Hall in February, 1914. 



Obs. — At Soarclifi, Mistake Basin, and Mount Algidus. over fifty miles 

 west of Methven, in Canterbury, Mr. Hall found three specimens, one of 

 them a male, measuring 10 mm. by 4|mm. These are not satisfactorily 

 difEerentiated 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 rugicoUis 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 sHghtly 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 Hkely to disregard, and as the elytral apices are evidently 

 sinuate, I think this nuist be a valid species. 



?. Length, 10 mm. ; breadth, nearly 4 mm. 



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 feebly irregularly striate, sometimes longitudinally near the middle of
