CNEMACANTHIDAE. 355 



Mount Alfred, near Paradise, north of Lake Wakatipii, at elevations 

 •of from 200 ft. to 3,000 ft. Three examples from Mr. T. Hall between 

 the 4th and 9th February, 1914, and another from Harris Saddle farther 

 north-west. 



3790. Mecodema latulum sp. nov. 



Oblong, slightly convex, nitid ; black, legs and antennae piceous. 



Head, including the moderately prominent eyes, equalling the thoracic 

 apex in width ; vertex minutely and distantly, occiput distinctly and 

 closely punctate ; interocular striae subtransversal and shallow, epistome 

 very minutely and densely pimctured, its longitudinal grooves not deep. 

 Thorax moderately incurved in front, quite truncate at the base, a sixth 

 broader than long in the middle ; its sides indistinctly crenulate and 

 moderately rounded, distinctly but not abruptly narrowed behind the 

 middle, the base with straight sides and rectangular angles ; disc nearly 

 plane, with shallow striae across it, base and apex without well-marked 

 longitudinal ones, the latter with a few punctiform impressions near its 

 angles, basal fossae deep but not elongate. Elytra more than double the 

 length of thorax, a sixth broader, slightly narrowed towards, yet rather 

 broader than, the base of the thorax, hardly at all narrower behind ; they 

 are finely substriate-punctate near the suture, with plane interstices ; the 

 •outer 4 series, 6th and 7th particularly, are more deeply, though not 

 very coarsely, punctate-striate, with convex interstices ; sublateral space 

 smooth above, but rather coarsely and irregularly pimctate below ; apical 

 sculpture irregular and coarser than that of the disc. 



Legs, antennae, and palpi normal. 



Prosternum nearly smooth along the middle, its flanks distinctly and 

 moderately closely pimctured, sides of mesosternum more closely, meta- 

 sternum nearly smooth, sides of abdomen Avith fine irregular wrinkles, apex 

 of last segment bipimctate at each side of the middle. 



Li shape somewhat similar to M. huttense (3680), but much less narrowed 

 posteriorly, and with very different sculpture. 



2. Length, 22 mm. ; breadth, 7 mm. 



Ben Lomond. One discovered by Mr. T. Hall on the 3rd March, 1914, 

 at a height of about 4,000 ft. 



3791. Mecodema affinum sp. nov. 



Nearly lelated to 31. latulum, but differing therefrom as detailed 

 below. 



Body less shining. Thorax rather more rounded, slightly wider at the 

 middle than elsewhere, abruptly contracted at the base ; smooth above, 

 with very few fuie punctures near its anterior angles. El}i;ra rather more 

 narrowed behind, with well-marked regular striae ; these are quite dis- 

 tinctly and regularly punctured throughout, the outer ones rather more 

 coarsely ; 3rd interstices lather broader than the others, and, like the suture, 

 subcostatc behind, 6th and 7th quite costiforra, 8th still narrower, all more 

 or less confluent behind. 



?. Length, 23 mm. ; breadth, 7| mm. 



Mount Dick, west of Lake Wakatipu, near Kingston. Unique. Found 

 by Mr. T. Hall, at an elevation of 2,500 ft., on the 27th February, 1914.
