OF NEW ZEALAND. 979 



Larger than my example of M. monllifcr, the thoracic margins 

 and channels different, and distinguished from all the other recorded 

 species by the two large interocular punctm-es. The minute 

 asperities on the hinder portion of the wing-cases may be detected 

 on M. mfipes, but that insect is altogether more brilliant and other- 

 wise dissimilar. 



^ . Length, 9^ ; breadth, 3 lines. 



One, found by Mr. S. W. Fulton, 9th November, 1882, at the 

 sea-beach, Taieri. 



1763. M. junctum, ^^-s. Black, not glossy, legs rufo-piceous ; 

 palpi, tarsi, and antenna? paler. 



Very much like M. aspcrum, but the thorax is relatively broader 

 and of much more rounded outline, the marginal channels are 

 diminished, and its base is truncate. The hind tibiae are less 

 asperate, and not so much prolongated apically. 



Length, 8 ; breadth, 2f lines. 



I am indebted to Mr. S. W. Fulton for my specimen, which was 

 found at Strath-Taieri. 



Note. — Metaghjmvia lyuncticcps (No. 1323) and ill. csneoniger 

 (No. 1453) must be placed in the genus Mecodema. Li both these 

 species the seven terminal articulations of the antennte are pubes- 

 cent, and the tibite are not dilated apically. 



1764. M. sulcatum, ^i-s- {Sharp; Trans. Botj. Dublin Soc, 

 Nov., 1886.) Nigrum, antennis pedibusque piceis ; prothorace im- 

 punctato, canalicula longitudinali impresso; ehjtris fortiter pro- 

 fundeque punctato-sulcatis. 



Long., 18mm. 



Head without punctures or wrinkles ; with prominent eyes, and 

 very indistinct postocular constriction. Tliorax with a length nearly 

 seven-eighths of the width, a little rounded at the sides, considerably 

 narrowed behind, and with a gentle, not abrupt, basal sinuation ; 

 tlie surface without sculpture, transversely convex ; the side margin 

 not crenate, but infringed on by the punctures bearing the intra- 

 marginal tactile setge, of which there are six on each side ; hind 

 angles rather obtuse, the lateral foveae indistinct. Elytra large, 

 parallel-sided, with regular, very broad, deep strite, bearing coarse 

 punctures. Front tihice with moderately long apical prolongation ; 

 middle tibia} a little, hind tibiaj scarcely at all, incrassate at tip. 



This bears a considerable resemblance to M. monilifer, Bates, the 

 typical species of the genus, but is distinct by some important 

 characters ; the antennoe are shorter, and the pubescent areae on 

 their upper and lower margins are greater ; the thorax has a basal 

 prolongation ; the elytra are deeply sulcate, and the tibiae much less 

 dilated at the extremity. 



Picton. Helms ; three examples, in bad condition. 



Note. — Dr. Sharp states that he considers Castelnau's Mcfa- 

 glymma clivinoides, No. 29, to be a Diglymma. — T.B.
