358 COLEOPTERA. 
Klytra oblong-oval, a little wider than thorax at the base, nearly thrice its 
length ; along each elytron there are three somewhat indefinite, irregular, 
smooth dorsal lines, these are distinct at the base but become obsolete 
behind; the sculpture between the suture and 2nd is irregularly but not 
deeply punctiform, that beyond consists of more or less transverse but 
very irregular impressions, these are sometimes divided into suboblong 
areas by smooth, transverse, linear connections between the 2nd and 3rd 
longitudinal lines; the common smooth costa near the side is narrow, it 
does not reach the apex, and, before the middle, is quite obliterated by the 
coarse lateral sculpture. 
At first sight, owing to the elytral sculpture, this may seem like M. lewisi 
(2604), but as the thoracic margins are crenulate it really belongs to a 
different section of the genus. The thorax is differently shaped, and instead 
of having rather thin, nearly flat lateral margins as in M. lewisi, they are 
thicker and slightly reflexed. 
Length, 34-37 mm.; breadth, 10-11 mm. 
Gordon’s Knob, near Belgrove. Four individuals received from Mr. 
T. Hall, who spent three days on the mountain in November, 1914. 
3796. Diglymma basale sp. nov. Dziglymma Sharp, Man. N.Z. Coleopt., 
p. 980. 
Elongate, narrow, moderately convex, nitid; black, mandibles, legs, 
and antennae rufo-piceous, tarsi and palpi more rufescent. 
Head nearly as broad as front of thorax, somewhat depressed and 
punctate behind the eyes, generally with a few finer punctures alongside 
the broad plica near each eye. Thorax apparently elongate, really of 
almost equal length and breadth, base and apex truncate, its sides dis- 
tinetly and evenly margined, moderately rounded, more strongly behind 
so that the straight-sided base seems a good deal contracted, posterior 
angles rectangular; disc almost smooth, having only some feeble, often 
obsolete striae across it, basal fossae elongate and deep and situated close 
to the sides, the mtervening space finely and sparingly punctured, the 
middle of the apex with similar punctures and obsolete longitudinal striae, 
mesial groove well marked but not reaching the base or apex. Elytra 
oblong-oval, double the length of thorax, broader near the middle, their 
shoulders gently curved, yet a little wider than the thoracic base and with 
rather thicker margins than the sides ; their finely but distinctly punctured 
striae are moderately deep near the suture, sometimes obsolete near the 
apices, the sides with several large punctures ; interstices almost plane. 
Intermediate tibae slender at the base, expanded below the middle. 
Underside shining. Flanks of prosternum rather distantly punctate, 
the abdomen less distinctly near the sides, apex of last segment quadri- 
punctate. 
D. marginale (3507) is distinguishable by the long sinuation of the side 
of the thorax towards the more sharply marked posterior angle, by the 
more strongly developed elytral margins and less convex body. Sharp’s 
D. ovipenne (1766) has apparently more deeply striate elytra, and the base 
of the thorax and its angles seem different. 
Length, 12-15 mm.; breadth, 4-5 mm. 
Ben Lomond, Mount Alfred, and Routeburn. Several specimens were 
found by Mr. T. Hall, at elevations of 2,000 ft. to 4,000 ft., during February, 
1914.
