356 COLEOPTERA. 
3792. Mecodema indiscretum sp. noy. 
Oblong, slightly nitid. 
Head without frontal striae and interocular rugae, the occiput finely 
but not closely punctured. Thorax with simple and rather narrow margins, 
smooth above. Elytra rather broader behind than in M. affinum, not at all 
distinctly punctate-striate. 
Distinguishable from M. latulum by its emarginate base, narrow lateral 
margins, and smooth dise of the thorax. The elytral sculpture is nearly 
similar, being finely substriate-punctate near the suture, but the 6th striae 
are deeper, broader, and more distinctly and regularly punctate, and, before 
the middle, are obviously and coarsely quadripunctate. The labrum, 
instead of being plane, has a broad, oblong, central groove. 
These are not sexual variations, as the types of M. latulum, M. affinum, 
as well as this species are females. 
Q. Length, 24 mm.; breadth, 8 mm. 
Mount Earnslaw, north of Lake Wakatipu. A single specimen found 
by Mr. T. Hail on the 6th February, 1914. 
3793. Mecodema trailli sp. nov. 
Elongate, only moderately convex, nitid; black, antennae and legs 
piceous. 
Head iather narrower than thoracic apex, with deep longitudinal 
frontal sulci, those near the eyes also deep but irregular, and between these 
latter there are some fine transversal ones ; it 1s closely and distinctly pune- 
tured behind the eyes but smooth at its base. Thorax a fifth broader than 
long, base and apex subtruncate, its sides slightly crenulate, moderately 
rounded from the front to bey ond the middle, more curvedly narrowed 
behind, its base more contracted, with almost straight sides and obtusely 
rectangular angles ; the surface with very fine striae across it, basal and 
apical longitudinal striae quite obsolete; there is a foveiform impression 
near each anterior angle, mesial groove nearly entire, basal fossae deep 
and moderately elongate. Elytra elongate-oval, a good deal narrowed 
posteriorly, nearly thrice as long as the thorax, and rather wider than it 
is at the base; their striae regular, almost equally finely punctured from 
the suture to the sides, the 7th with 3 or 4 rather larger setigerous punc- 
tures, their sides nearly vertical, with shallow indefinite impressions ;_ in- 
terstices nearly plane near the suture, moderately convex towards the sides. 
the apical sculpture irregular. 
Legs, antennae, and palpi normal. The eyes, owing to a slight orbital 
dilatation underneath, appear less prominent than usual. 
Underside shining. Prosternum smooth on the middle, its flanks 
moderately punctured, sides of mesosternum more closely, abdomen finely 
and irregularly wrinkled, longitudinally at the sides, its last segment trans- 
versely, its apex with 3 setigerous punctures near one side but only 2 at 
the other. 
This bears more resemblance to the northern M. seitulwm (2593), measur- 
ing 29 mm. by 9 mm., than to any South Island species. The present species 
is much more slender, its thorax is rélatively broader, more contracted at the 
base, and the lateral channels are no wider in front than behind the middle ; 
the antennae and legs are a little stouter, and the sculpture of the under- 
side differs considerably.
