CNEMACANTHIDAE. 355 
Mount Alfred, near Paradise, north of Lake Wakatipu, 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 punctured, 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 punctate 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 punctured, sides of mesosternum more closely, meta- 
sternum nearly smooth, sides of abdomen with fine irregular wrinkles, apex 
of last segment bipunctate at each side of the middle. 
In 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 related to M. latulum, but differimg therefrom as detailed 
below. 
Body less shinmg. Thorax rather more rounded, slightly wider at the 
middle than elsewhere, abruptly contracted at the base; smooth above, 
with very few fine punctures near its anterior angles. Elytra 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 rather broader than the others, and, like the suture, 
subcostate behind, 6th and 7th quite.costiform, 8th still narrower, all more 
or less confluent behind. 
2. Length, 23mm.; breadth, 74 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.
