466 COLEOPTERA. 



broad as long, apex widely emarginate, base feebly sinuate or oblique near 

 eacb side, with i-ectaugular angles ; its sides finely margined, slightly 

 curvedly narrowed towards the obtuse anterior angles ; the surface finely, 

 iri'egularly, and distantly punctate. Scutolluni smooth, distinct, tri- 

 angular. Elytra of the same width as thorax at the base, more than double 

 its length, distinctly margined and curvedly narrowed behind ; they are 

 irregularly and moderately coarsely subseriate-punctate nearly to the 

 apices, the base, however, is nearly smooth at the middle, the intervals 

 between the series are more finely, irregularly, and distantly punctured. 



Legs stout, tibiae arcuate externally and, at the extremity, bearing 

 some yellowish pubescence. Basal joint of tarsi moderately enlarged, 

 that of the anterioi' subcordate, the 2nd very small. Underside con- 

 colorous. 



At first sight I thought this might be Sharp's C. globosus (2297), but 

 the form seemingly is less rotimdate, whilst the nigrescent sternum and 

 underside of the head, and irregular sculpture of the elytra, prove it to be 

 distinct. 



S- Length, 3 mm. ; breadth, 2J mm. 



HoUyford. A single male found by Mr. T. Hall, on the 19th February, 

 1914, amongst decaying vegetable matter. 



3964. Caccomolpus hallianus sp. nov. 



Convex, broadly oval, nitid ; aeneo-niger, antennae and legs rufo- 

 testaceous. 



Head fii\ely punctate and iisually bi -impressed between the eyes, and 

 with a median longitudinal depression behind. Thorax nearly thrice as 

 broad as long ; disc distinctly and moderately fuiely punctate, the sides 

 obsoletely. Scutellum smooth. Elytra rather more than thrice the length 

 of thorax, with irregular series of fine pimctures, these are not coarser 

 than those on the thorax and are nearly absent from the sides, middle 

 of the base, and apices, the interstices even more finely, distantly, and 

 irregularly punctate ; pygidium somewhat exposed. 



Underside nigro-aeneous and somewhat iridescent, more oi' less finely 

 punctate and, femora inclusive, with fine depressed setae ; prosternum 

 obtusely convex between the coxae. 



Considerably larger than C. nigrivetitris, less glossy and aeneous, and 

 with manifestly finer elytral punctation, that of the thorax, however, is 

 more distinct. 



Tibiae strongly arched externally, but not angulate, the anterior 

 distinctly punctate and pubescent below the middle ; basal tarsal joints 

 of the male dilated, that of the anterior rather longer than broad and 

 therefore less broadly cordiform than in C. nigriventris. 



Length, 5 mm. ; breadth, 3J mm. 



Mount Dick, Lake Wakatipu. A female, taken by Mr. T. Hall from 

 decaying leaves on the 29th January, 1914, and three others, including the 

 male, duiiiig two days collecting on that mountain during March. 



3965. Caccomolpus fuscicornis s]). nov. 



Nitid, aeneo-niger ; legs and antennae fuscous, the former more 

 rufescent. 



This most nearly resembles the same sex of C. liaUidinis. but is 

 differentiated by the narrowei- elytral apices, which cover the pygidium,
